The RTF standard provides a format for text and graphics interchange that can be used with different output devices, operating environments, and operating systems. RTF uses the ANSI, PC-8, Macintosh, or IBM PC character set to control the representation and formatting of a document, both on the screen and in print. With the RTF standard, you can transfer documents created under different operating systems and with different software applications among those operating systems and applications. Software that takes a formatted file and turns it into an RTF file is called a "writer." An RTF writer separates the applicationÆs control information from the actual text and writes a new file containing the text and the RTF groups associated with that text. Software that translates an RTF file into a formatted file is called a "reader." RTF SYNTAX ========== An RTF file consists of unformatted text, control words, control symbols, and groups. For ease of transport, a standard RTF file can consist of only 7-bit ASCII characters. However, Word for Windows uses 8-bit characters in the RTF stream given to converter DLLs. A "control word" is a specially formatted command that RTF uses to mark printer control codes and information that applications use to manage documents. A control word takes the following form: \<LetterSequence>[<NumericParameter>]<delimiter> For example: A B C | | | | ----- | \ r t f 1 A A backslash begins each control word B Letter sequence C Numeric parameter The "Letter Sequence" is made up of uppercase or lowercase alphabetic characters between A and Z inclusive. The "Numeric Parameter" begins with a digit or a minus sign (-). The range of the values for the numeric parameter is -32,767 through 32,767. However, Microsoft Word for Windows, Word for OS/2, and Word for the Macintosh restrict the range to -31,680 through 31,680. If a numeric parameter immediately follows the control word, this parameter becomes part of the control word and the delimiter follows the parameter. The "delimiter" marks the end of an RTF control word or symbol. A delimiter can be one of the following: - A space. If a space delimits a control word, the space does not appear in the document. Any characters following the delimiter, including spaces, do appear in the document. For this reason, you should use spaces only where necessary; do not use spaces merely to break up RTF code. - A backslash (\), opening brace ({), or closing brace (}). These characters are used to mark the beginning of a new control word or symbol, the beginning of a group, and end of a group, respectively. More information about control symbols and groups is provided later in this document. - Any character other than a letter or a digit. In this case, the character terminates the control word but is not actually part of the control word. The character is considered part of the document text. Some control words govern properties that have only two states (for example, bold, which is either turned on or turned off). When such a control word has no parameter or has a nonzero parameter, it is assumed that the control word turns on the property. When such a control word has a parameter of 0 (zero), it is assumed that the control word turns off the property. For example, \b turns on bold, whereas \b0 turns off bold. A "control symbol" consists of a backslash followed by a single, nonalphabetic character. For example, \~ represents a nonbreaking space. Control symbols take no delimiters. A "group" consists of text and control words or control symbols enclosed in braces ({ }). The opening brace indicates the start of the group and the closing brace indicates the end of the group. Each group specifies the text affected by the group and the different attributes of that text. The RTF file can also include groups for fonts, styles, screen color, pictures, footnotes, annotations, headers and footers, summary information, fields, and bookmarks, as well as document-, section-, paragraph-, and character-formatting properties. If the font, style, screen color, and summary information groups and document formatting properties are included, they must precede the first plain- text character in the document. These groups form the RTF file header. If the group for fonts is included, it should precede the group for styles. If any group is not used, it can be omitted. The groups are discussed in the following sections. Certain groups, referred to as "destinations," mark the beginning of a collection of related text that could appear at another position, or destination, within the document. Destinations can also be text that is used but should not appear within the document at all. Destinations are sometimes distinguished from other groups by a \* control symbol immediately following the opening brace of the group. The \* is followed by a control word that defines the type of the destination. This control symbol identifies destinations whose related text should be ignored if the RTF reader does not recognize the destination. (RTF writers should follow the convention of using this control symbol when adding new control words.) Destinations whose related text should be inserted into the document even if the RTF reader does not recognize the destination should not use \*. An example of a destination is the \footnote group, where the footnote text follows the control word. Formatting specified within a group affects only the text within that group. Generally, text within a group inherits the formatting of the text in the preceding group. However, Microsoft implementations of RTF assume that the footnote, header and footer, and annotation groups (described later in this document) do not inherit the formatting of the preceding text. Therefore, to ensure that these groups are always formatted correctly, you should set the formatting within these groups to the default with the \sectd, \pard, and \plain control words, and then add any desired formatting. The control words, control symbols, and braces constitute control information. All other characters in the file are plain text. The following is an example of plain text that does not exist within a group: ... \linex0endnhere \pard\plain \fs20 This is plain text. ... The phrase, "This is plain text" is not part of a group and is treated as document text. As previously mentioned, the backslash (\) and braces ({ }) have special meaning in RTF. To use these characters as text, precede them with a backslash, as follows: \\ \{ \} CONVENTIONS OF AN RTF READER ============================ The reader of an RTF stream is concerned with the following: - Separating control information from plain text - Acting on control information - Collecting and properly inserting text into the document, as directed by the state of the current group The process of acting on control information is designed to be relatively simple. Some control information only contributes special characters to the plain text stream. Other information changes the "program state," which includes properties of the document as a whole, or changes a collection of "group states," which applies to parts of the document. As previously mentioned, a group state can specify the following: - The "destination," or part of the document that the plain text is constructing - Character formatting properties, such as bold or italic - Paragraph formatting properties, such as justified or centered - Section formatting properties, such as the number of columns - Table formatting properties, which define the number of cells and dimensions of a table row An RTF reader performs the following procedure: 1. The reader reads the next character. 2. If the next character is: - An opening brace, the reader stores the current state of the document on the stack. - A closing brace, the reader retrieves the current state of the document from the stack. - A backslash, the reader marks the beginning of an RTF control. The reader collects the control word or control symbol and its parameter, if any, and carries out the action prescribed for that control. The meaning of each of the controls is discussed in the section "Contents of an RTF File" in this document. The read pointer is left on the next nonspace delimiter following the control. - Anything other than an opening brace, closing brace, or backslash, the reader assumes that the character is plain text and writes the character to the current destination using the current formatting properties. 3. The reader then reads the next character. If the RTF reader does not recognize a particular control word or control symbol, the reader ignores it. When the reader encounters a control word or control symbol preceded by an opening brace, the reader recognizes the control as part of a group. The reader saves the current state on the stack but does not change the state. When the reader encounters a closing brace, the reader retrieves the current state from the stack, thereby resetting the current state. If the \* control symbol precedes the unknown control word, \* defines a destination group and is preceded by an opening brace. The RTF reader will discard all text and subgroups up to and including the brace that closes this group. For control words or control symbols recognized by the RTF reader, the possible actions are as follows: Action Description ------ ----------- Change The RTF reader changes the destination to destination the destination described in the table entry. Destination changes are legal only immediately after an opening brace. (Other restrictions may also apply; for example, footnotes cannot be nested.) Many destination changes imply that the current property settings will be reset to their default settings. Examples of control words that change the destination are \footnote, \header, \footer, \pict, \info, \fonttbl, \stylesheet, and \colortbl. Change The RTF reader changes the property as formatting described in the table entry. The entry property specifies whether a parameter is required. Insert special The reader inserts into the document the character character code or codes described in the table entry. Insert special The reader inserts into the document the character and character code or codes described in the perform action table entry and performs whatever other action the entry specifies. For example, when Microsoft Word interprets \par, Word inserts a paragraph mark in the document, along with the paragraph properties belonging to that paragraph mark. CONTENTS OF AN RTF FILE ======================= An RTF file can contain combinations of the following elements: THE RTF VERSION =============== An entire RTF file is considered a group and must be enclosed in braces. The control word \rtf<N> must follow the opening brace. The numeric parameter <N> identifies the version of the RTF standard used. The RTF standard described in this document is version 1.0. THE CHARACTER SET ================= After specifying the RTF version, you must declare the character set. The control word for the character set must precede any plain text or any table control words. The RTF specification currently supports the following character sets: Control Word Character Set ------------ ------------- \ansi ANSI (the default) \mac Apple Macintosh \pc IBM(R) PC Code Page 437 \pca IBM PC Code Page 850, used by IBM Personal System/2(R) (not implemented in version 1.0 of Microsoft Word for OS/2) The Font Table -------------- This group begins with the control word \fonttbl and contains descriptions of fonts. All fonts available to the RTF writer can be included in the font table, even if the document doesnÆt use all the fonts. A font is defined by a font number, a font family, and a font name as shown in the following example: A B C D | | | | -------- | ------- --------- {\fonttbl\f0\froman Tms Rmn;}... A Control word B Font number C Font family D Font name Semicolons separate one font from the next. The font numbers represent the full font definitions in the group and vary with each document. The font families are listed below: Control Word Font Family ------------ ----------- \fnil Unknown or default fonts (the default) \fRoman Roman, proportionally spaced serif fonts (for example, Times Roman(R) and Palatino(R)) \fswiss Swiss(TM), proportionally spaced sans serif fonts (for example, Swiss Helvetica(R)) \fmodern Fixed-pitch serif and sans serif fonts (for example, Courier and Pica) \fscript Script fonts (for example, Cursive) \fdecor Decorative fonts (for example, Old English and ITC Zapf Chancery(R)) \ftech Technical, symbol, and mathematical fonts (for example, Symbol) If an RTF file uses a default font, the default font number is specified with the \deff<N> control word, which must precede the font- table group. The RTF writer supplies the default font number used in the creation of the document as the numeric argument <N>. The RTF reader then translates this number through the font table into the most similar font available on the readerÆs system. THE STYLE SHEET =============== The style sheet group begins with the control word \stylesheet. This group contains definitions and descriptions of the various styles used in the document. The style sheet is declared only once, before any document text. All styles in the documentÆs style sheet can be included, even if not all the styles are used. Control Word Meaning ------------ ------- \sbasedon<N> Defines the number of the style on which the current style is based. Word for Windows defaults to the Normal style--style number 222--if \sbasedon is omitted. \snext<N> For paragraph styles, \snext defines the style automatically assigned to a paragraph created following the paragraph with the current style. If \snext omitted, the next paragraph is given the same style as the current paragraph. \keycode Specified within the description of a style in the style sheet in the RTF header. The syntax for this group is {\*\keycode <Keys>} where <Keys> are the characters used in the key code. For example, a Normal style may be defined {\s0 {\*\keycode \shift\ctrl n}Normal;} within the RTF style sheet. See the "Special Characters" control words for the characters outside of the alphanumeric range that can be used. An example of an RTF style sheet and styles follows: ... -- | {\stylesheet{\fs20 \sbasedon222\snext10{keycode \shift...} A---| {\s1 \ar \fs20 \sbasedon0\snext1 FLUSHRIGHT}{\s2\fi...} | \sbasedon0snext2 IND:}} -- ... -- | \widowctrl\ftnbj\ftnrestart \sectd \linex0\endnhere | \pard\plain \fs20 This is Normal style. B---| \par \pard\plain \s1 | This is right justified. I call this style FLUSHRIGHT. | \par \pard\plain \s2 | This is an indented paragraph. I call this style IND... -- \par} ... A Style sheet B Styles applied to text This is Normal Style. This is right justified. I call this style FLUSHRIGHT. This is an indented paragraph. I call this style IND. It produces a hanging indent. In this example, PostScript(R) is declared but not used. Some of the control words in this example are discussed in the following sections. THE COLOR TABLE =============== Screen colors, character colors, and other color information are contained in the color table group. The control word \colortbl begins this group. Additional control words for red, green, and blue and the foreground and background colors then use parameter values (0-255) corresponding to the color indexes used by Microsoft Windows to define the amount of red, green, and blue that makes up a color. For more information on color setup, see your Windows documentation. The following are valid control words for this group: Control Word Meaning ------------ ------- \red<N> Red index \green<N> Green index \blue<N> Blue index \cf<N> Foreground color (the default is 0) \cb<N> Background color (the default is 0) Each definition must be delimited by a semicolon, even if the definition is omitted. If a color definition is omitted, the RTF reader uses its default color. In the example that follows, three colors are defined. The first color is omitted, as shown by the semicolon following the \colortbl control word. ... {\colortbl;\red0\green0\blue0;\red0\green0\blue255;} ... The following example defines a block of text in color (where supported). Note that the cf/cb index is the index of an entry in the color table, which represents a red/green/blue color combination. ... {\f1\cb1\cf2 This is colored text. The background is color 1 and the foreground is color 2. ... If the file is translated for software that does not display color, the reader ignores the color table group. PICTURES ======== An RTF file can include picture files created with other applications. These files are in hexadecimal (the default) or binary format. The control word \pict begins this group. Control words that define and describe the picture parameters follow the \pict control word. These control words are listed in the following table (some measurements in this table are in twips; a twip is one-twentieth of a point): General -------------------------------------------------------------------- Control Word Meaning ------------ ------- \macpict The source file of the picture is QuickDraw(TM). \pmmetafile<N> The source file of the picture is an OS/2 metafile; the <N> argument identifies the metafile type. \wmetafile<N> The source file of the picture is a Windows metafile; the <N> argument identifies the metafile type (the default is 1, meaning the metafile type is MM_TEXT). \dibitmap<N> The source file of the picture is a device independent bitmap; the <N> argument identifies the bitmap type (the default is 0). \wbitmap<N> The source file of the picture is a bitmap; the <N> argument identifies the bitmap type (the default is 0, meaning that the bitmap is a logical bitmap). Bitmap Information -------------------------------------------------------------------- Control Word Meaning ------------ ------- \wbmbitspixel<N> The number of bitmap bits per pixel (the default is 1). \wbmplanes<N> The number of bitmap planes (the default is 1). \wbmwidthbytes<N> The bitmap width in bytes. Picture Size, Scaling, and Cropping -------------------------------------------------------------------- Control Word Meaning ------------ ------- \picw<N> The <xExt> field if the picture is a metafile; the picture width in pixels if the picture is a bitmap or is from QuickDraw. \pich<N> The <yExt> field if the picture is a metafile; the picture height in pixels if the picture is a bitmap or from QuickDraw. \picwgoal<N> The desired width of the picture in twips. \pichgoal<N> The desired height of the picture in twips. \picscalex<N> The horizontal scaling value; the <N> argument is a value representing a percentage (the default is 100). \picscaley<N> The vertical scaling value; the <N> argument is a value representing a percentage (the default is 100). \picscaled Scales the picture to fit within the specified frame; used only with \macpict pictures. \piccropt<N> The top cropping value in twips; a positive value crops toward the center of the picture; a negative value crops away from the center, adding a space border around the picture (the default is 0). \piccropb<N> The bottom cropping value in twips; a positive value crops toward the center of the picture; a negative value crops away from the center, adding a space border around the picture (the default is 0). \piccropl<N> The left cropping value in twips; a positive value crops toward the center of the picture; a negative value crops away from the center, adding a space border around the picture (the default is 0). \piccropr<N> The right cropping value in twips; a positive value crops toward the center of the picture; a negative value crops away from the center, adding a space border around the picture (the default is 0). Picture Border -------------------------------------------------------------------- Control Word Meaning ------------ -------- \brdrs A single picture border. \brdrdb A double picture border. \brdrth A thick picture border. \brdrsh A shadow picture border. \brdrdot A dotted picture border. \brdrhair A hairline picture border. \brdrw<N> <N> is the width in twips of the picture border line. This control should follow the picture border controls \brdrt, \brdrr, \brdrb, and \brdrl. \brdrcf<N> <N> is the color of the picture border from the color table in the RTF header. This control should follow the picture border controls \brdrt, \brdrr, \brdrb, and \brdrl. Picture Background Shading -------------------------------------------------------------------- Control Word Meaning ------------ ------- \shading<N> <N> is the shading of the picture in hundredths of a percent. \bghoriz Specifies a horizontal background pattern for the picture. \bgvert Specifies a vertical background pattern for the picture. \bgfdiag Specifies a forward diagonal background pattern for the picture (\\\\). \bgbdiag Specifies a backward diagonal background pattern for the picture (////). \bgcross Specifies a cross-hatched background pattern for the picture. \bgdcross Specifies a diagonal cross-hatched background pattern for the picture. \bgdkhoriz Specifies a dark horizontal background pattern for the picture. \bgdkvert Specifies a dark vertical background pattern for the picture. \bgdkfdiag Specifies a dark forward diagonal background pattern for the picture (\\\\). \bgdkbdiag Specifies a dark backward diagonal background pattern for the picture (////). \bgdkcross Specifies a dark cross-hatched background pattern for the picture. \bgdkdcross Specifies a dark diagonal cross-hatched background pattern for the picture. \cfpat<N> <N> is the line color of the background pattern. \cbpat<N> <N> is the background color of the background pattern. Picture Data -------------------------------------------------------------------- Control Word Meaning ------------ ------- \bin<N> The picture is in binary format; the numeric parameter <N> is the number of bytes that follow. The \wbitmap control word is optional; if neither \wmetafile nor \macpict is specified, the picture is assumed to be a Windows bitmap. If \wmetafile is specified, the <N> argument can be one of the following types: Type <N> Argument ---- ------------- MM_TEXT 1 MM_LOMETRIC 2 MM_HIMETRIC 3 MM_LOENGLISH 4 MM_HIENGLISH 5 MM_TWIPS 6 MM_ISOTROPIC 7 MM_ANISOTROPIC 8 If \pmmetafile is specified, the <N> argument can be one of the following types: Type <N> Argument ---- ------------- PU_ARBITRARY 4 PU_PELS 8 PU_LOMETRIC 12 PU_HIMETRIC 16 PU_LOENGLISH 20 PU_HIENGLISH 24 PU_TWIPS 28 Be careful with spaces following control words when dealing with pictures in binary format. When reading files, RTF considers the first space after a control word the delimiter and subsequent spaces part of the document text. Therefore, any extra spaces are attached to the picture, with unpredictable results. RTF writers should not use the carriage-return/linefeed (CRLF) combination to break up pictures in binary format. If they do, the CRLF is treated as literal text and considered part of the picture data. The picture in hexadecimal or binary format follows the picture-group control words. The following example illustrates the group format: A B C D E | | | | | -------- ------- ------ ------------- ---------- {\pict\wbitmap0\picw170\pich77\wbmbitspixel1\wbmplanes1 F G | | --------------- ----------- \wmbwidthbytes22\picwgoal505 H--- \pichgoal221 I--- \picscalex172 J--- \picscaley172 - 49f2000000000273023d1101a030 | 3901000a000000000273023d98 | 0048000200000275 | 02040000200010275023e000000000 K--| 273023d000002b90002b90002 | b90002b90002b9 | 0002b90002b90002b90002b90002b90002 | b92222b90002b90002b90 | 002b90002b9 - 0002b90002b90002b90002b9000 ... A Source B Width C Height D Bits per pixel E Bitmap planes F Width of picture in bytes G Desired picture width H Desired picture height I Horizontal scaling value J Vertical scaling value K Hexadecimal data NOTE: The controls \pichgoal, \picscalex, and \picscaley in this example are on separate lines for the purpose of illustration only. In actual RTF code, they can be included on the same line. FOOTNOTES ========= The group containing footnote text begins with the control word \*\footnote. Footnotes are anchored to the character that immediately precedes the footnote group. If automatic footnoting is defined, the group can be preceded by a footnote reference character, identified by the control word \chftn. The following is an example of a group containing footnotes: ... \ftnbj\ftnrestart \sectd \\linemod0\linex0\endnhere \pard\plain \ri1170 \fs20 {pu6 Mead's landmark study has been amply annotated.\chftn A--| {\*\footnote \pard\plain \s246 \fs20 {\up6\chftn }See Sahlins, | Bateson, and Geertz for a complete bibliography.} It was her work in America during the Second World War, however, that forms the basis for the paper. As others have noted, \chftn A--| {\*\footnote \pard\plain \s246 \fs20 {\up6\chftn} | A complete bibliography will be found at the end of the | chapter.} this period was a turning point for Margaret Mead.} \par ... Mead's landmark study has been amply annotated.1 It was her work in America during the Second World War, however, that forms the basis for this paper. As others have noted,2 this period was a turning point for Margaret Mead. 1 See Sahlins, Bateson, and Geertz for a complete bibliography. 2 A complete bibliography will be found at the end of the chapter. A: Footnotes For other control words relating to footnotes, see the sections titled "Document Formatting Properties," "Section Formatting Properties," and "Special Characters" later in this document. ANNOTATIONS =========== The group containing annotation text begins with the control word \*\annotation. Annotations are anchored to the character that immediately precedes the annotation group. The group must be preceded by an annotation reference character identified by the control word \chatn. The annotation reference character must in turn be preceded by a group that begins with the control word \*\atnid and that contains the identification text for the author of the annotation. An example of annotation text follows: ... An example of a paradigm might be Newtonian physics or Darwinian biology.{\v\fs16 {\atnid bz}\chatn{\*\annotation \pard\plain \s224 \fs20 {field{fldinst page \\*"'Page: '#\line'"}{\fldrslt}}{\fs 16 \chatn } How about some examples that deal with social science? That's what this paper is about.}} ... HEADERS AND FOOTERS =================== Headers and footers are treated as separate groups in RTF. Different headers and footers can be defined for different sections in the document. If none is defined for a given section, the headers and footers from the previous section (if any) are used. These groups must precede the first plain-text character in the document section to which they apply. The control words \header and \footer begin these groups. These control words can be replaced by the following control words, as appropriate: Control Word Meaning ------------ ------- \headerl The header is on left pages only. \headerr The header is on right pages only. \headerf The header is on the first page only. \footerl The footer is on left pages only. \footerr The footer is on right pages only. \footerf The footer is on the first page only. The \headerl and \headerr and \footerl and \footerr control words are used in conjunction with the \facingp control word, and the \headerf and \footerf control words are used in conjunction with the \titlepg control word. For more information, see "Document Formatting Properties" and "Section-Formatting Properties" in this document. SUMMARY INFORMATION =================== The RTF file can also contain a summary information group, which is translated but not displayed with the text. This information can include the title, author, keywords, comments, and other information specific to the file. This information is for use by a document- management utility, if available. This group begins with the control word \info. Some applications, such as Word, ask the user to type this information when saving the document in its native format. If the document is then saved as an RTF file or translated into RTF, the RTF writer specifies this information using the following control words. These control words are destinations, and both the control words and the text should be enclosed within braces ({ }). Control Word Meaning ------------ ------- \title The title of the document \subject The subject of the document \author The author of the document \operator The person who last made changes to the document \keywords Selected keywords for the document \comment Comments; text is ignored \version<N> The version number of the document \doccomm Comments displayed in WordÆs Summary Info dialog box The RTF writer can automatically enter other control words, including the following: Control Word Meaning ------------ ------- \vern<N> The internal version number \creatim The creation time \revtim The revision time \printim The last print time \buptim The backup time \edmins<N> The total editing time (in minutes) \yr<N> The year \mo<N> The month \dy<N> The day \hr<N> The hour \min<N> The minute \nofpages<N> The number of pages \nofwords<N> The number of words \nofchars<N> The number of characters \id<N> The internal ID number Entries without the <N> parameter have the \yr \mo \dy \hr \min format. An example of a summary information group follows: ... {\info{\title The Panda's Thumb}{\author Stephen J. Gould}{\keywords science natural history }} FIELDS ====== The field group contains the text of Word fields. For more detailed information on fields, choose Help in Microsoft Word for Windows. The field group begins with the control word \field. The following control words can follow the \field control word: Control Word Meaning ------------ ------- \flddirty A formatting change has been made to the field result since the field was last updated. \fldedit The text has been added to, or removed from, the field result since the field was last updated. \fldlock A field is locked and cannot be updated. \fldpriv A result is not in a form suitable for display (for example, binary data used by fields whose result is a picture). Two subgroups are available within the \field group. They must be enclosed within braces ({ }) and begin with the following control words: Control Word Meaning ------------ ------- \*\fldinst Field instructions \fldrslt The most recently calculated result of the field The \fldrslt control word should be included even if no result has been calculated because even readers that do not recognize fields can generally include the value of the \fldrslt group in the document. An example of field text follows: A B C | | | ----- -------------- ----------------- {\field\fldedit{\fldinst author}{\fldrslt Joe Smith}}\par\pard {\field{\fldinst time \\@ "h:mm AM/PM"}{\fldrslt 8:12 AM}} ----- ----------------------------- ----------------- | | | A B C A Begins field group B Field instructions C Field result INDEX ENTRIES ============= The index entry group begins with the control word \xe. Following this control word is the text of the index entry and other optional control words that further define the index entry. If the text of the index entry is not formatted as hidden text with the \v control word, the text is put into the document as well as into the index. For more information on the \v control word, see "Character Formatting Properties" in this document. Similarly, the text of the \txe subgroup, described later in this section, becomes part of the document if it is not formatted as hidden text. The following control words can also be used: Control Word Meaning ------------ ------- \bxe Formats the page number or cross-reference in bold \ixe Formats the page number or cross-reference in italic The following control words are destinations within the \xe group and are followed by text arguments. These control words and their arguments must be enclosed within braces ({ }) Control Word Meaning ------------ ------- \txe <Text> The text argument is to be used instead of a page number. \rxe <BookmarkName> The text argument is a bookmark for the range of page numbers. An example of an index entry follows: A B C D E F | | | | | | -- ------------- --------------- ------------- --- --- {\xe{\v Index Entry}{\rxe Index Range}{\txe See Index}\bxe \ixe } A Begins index-entry group B Entry text C Bookmark defining range of pages D Replacement for page number E Bold entry in index table F Italic entry in index table TABLE OF CONTENTS ENTRIES ========================= The table of contents entry group begins with the control word \tc. It is followed by the text of the table of contents entry and other optional control words that further define the group. As with index entries, text that is not formatted as hidden with the \v character-formatting control word is put into the document. The following control words can also be used in this group: Control Word Meaning ------------ ------- \tcf<N> The type of table being compiled; <N> is mapped by existing Microsoft software to a letter between A and Z (the default is 67, which maps to C and is used for tables of contents). \tcl<N> The level number (the default is 1). OBJECTS ======= Objects are structures in a document that contain a data portion and a result portion. The data portion generally appears hidden to the application that produced the document. A separate application uses the data and supplies the result or appearance of the data. This appearance is the result portion of the object. Some examples of objects include object linking and embedding (OLE) objects and Edition Manager Subscriber objects on the Macintosh platform. In RTF, the results of objects are represented so that RTF readers that donÆt understand objects or donÆt use a particular type of object are able to use the current result in place of the object. This allows the appearance of the object to be maintained through the conversion even though the object functionality is lost. For this reason, it is important for RTF writers to supply the object result. The format of the result should be standard RTF. The data portion of an OLE object is the structure produced from the OLE SaveToStream function. Some OLE clients rely on the OLE system to render the object, and a copy of the result is not available to the RTF writer for that application. For these cases, the object result can be obtained from the structure produced from the OLE SaveToStream function. An object group is defined by the control word \object. These objects can be either embedded objects, OLE links, or subscriber objects on the Macintosh platform. If the RTF readerÆs application does not use the type of object represented, then all the object information and data should be ignored and the object result should be inserted into the document in place of the object. Each object comes with optional information about the object, a required data group that contains the object data, and an optional result that contains the last display of the object. This result contains standard RTF. It is the responsibility of the RTF writer to provide the result so that existing RTF readers will be able to display the object without having full object support. The syntax for this group is as follows: {\object [\objemb|\objlink|\objautlink|\objsub|\objpub|\objicemb] [\linkself] [\objlock] [{\*\objclass <Name>}] [{\*\objname <Name>}] [\rsltmerge] [\rsltrtf|\rslttxt|\rsltpict|\rsltbmp] [\objsetsize] [\objalign<N>] [\objtransy<N>] [\objh<N> \objw<N>] [\objcropt<N>][\objcropb<N>][\objcropl<N>][\objcropr<N>] [\objscalex<N>][\objscaley<N>] {\*\objdata[{\*\objalias[\bin<N>] <Data>} {\*\objsect[\bin<N>] <Data>}] [\bin<N>] <Data>}<Result>} See the \result control word in the following table for a description of <Result>: Object Type -------------------------------------------------------------------- Control Word Meaning ------------ ------- \objemb An object type of OLE embedded object. If no type is given for the object, the object is assumed to be of type \objemb. \objlink An object type of OLE link. \objautlink An object type of OLE autolink. \objsub An object type of Macintosh Edition Manager subscriber. \objicemb An object type of MS Word for Macintosh Installable Command (IC) Embedder. Object Information -------------------------------------------------------------------- Control Word Meaning ------------ ------- \linkself The object is a link to another part of the same document. \objlock Locks the object from any updates. \objclass The syntax for the group is {\*\objclass <Name>} where <Name> is the name of the object class. This is optional in the \object group. \objname The syntax for group is {\*\objname <Name>} where <Name> is the name of the specific object instance. This is optional in the \object group. Object Size, Position, Cropping, and Scaling -------------------------------------------------------------------- Control Word Meaning ------------ ------- \objh<N> <N> is the original object height in twips. \objw<N> <N> is the original object width in twips. \objsetsize Forces the object server to set the objectÆs dimensions to those specified by the client. \objtransy<N> <N> is the distance in twips an object should be moved vertically with respect to the baseline. This control word is needed to place MathType(TM) equation objects correctly in line. This is an optional control of the \object group. \objcropt<N> <N> is the top cropping distance in twips. \objcropb<N> <N> is the bottom cropping distance in twips. \objcropl<N> <N> is the left cropping distance in twips. \objcropr<N> <N> is the right cropping distance in twips. \objscalex<N> <N> is the horizontal scaling percentage. \objscaley<N> <N> is the vertical scaling percentage. Object Data -------------------------------------------------------------------- Control Word Meaning ------------ ------- \objdata The \objdata subgroup is required to be in the \object group. The syntax for this group is {\*\objdata[{\*\objalias[\bin<N>] <Data>}{\*\objsect[\bin<N>] <Data>}][\bin<N>] <ObjectData>} where <ObjectData> represents the complete data of the object. If the \bin<N> option is used, then <N> represents the number of bytes of binary data. Otherwise, the <ObjectData >is in hexadecimal. \objalias This group contains the Alias Record for the publisher object for the Macintosh Edition Manager. If the \bin control is used, the data is in binary numerical format. Otherwise, it is represented in the RTF stream in hexadecimal. \objsect This group contains the Section Record for the publisher object for the Macintosh Edition Manager. If the \bin control is used, the data is in binary numerical format. Otherwise, it is represented in the RTF stream in hexadecimal. Object Result -------------------------------------------------------------------- Control Word Meaning ------------ ------- \rsltrtf Forces the result to be RTF, if possible. \rsltpict Forces the result to be a Windows metafile or MacPict image, if possible. \rsltbmp Forces the result to be a bitmap, if possible. \rslttxt Forces the result to be plain text, if possible. \rsltmerge Uses the formatting of the current result whenever a new result is obtained. \result The result group is optional in the \object group. It contains the last update of the result of the object. The data of the result group should be standard RTF so that RTF readers that donÆt understand objects or the type of object represented can use the current result in the objectÆs place to maintain the object's appearance. The syntax for this group is {\result <ResultData>} where <ResultData> is standard RTF syntax. BOOKMARKS ========= This group contains two control words: \*\bkmkstart, which indicates the start of the specified bookmark, and \*\bkmkend, which indicates the end of the specified bookmark. A bookmark is shown in the following example: ... \pard\plain \fs20 Kuhn believes that science, rather than discovering in experience certain structured relationships, actually creates (or already participates in) a presupposed structure to which it fits the data. {\bkmkstart paradigm} Kuhn calls such a presupposed structure a paradigm.{\bkmkend paradigm} ... If a bookmark covers a partial selection of columns of a table, \bkmkcolf<N> is used to denote the first column of a table covered by a bookmark and \bkmkcoll<N> is used to denote the last column. If \bkmkcolf is not included, the first column of the table is used as the first column for the bookmark. If \bkmkcoll is not included, the last column of the table is used for the bookmark. These controls are used within the \*\bkmkstart group following the \bkmkstart control. For example, {\*\bkmkstart\bkmkcolf2\bkmkcoll5 Table1} places the bookmark "Table1" on columns 2 through 5 of a table. MACINTOSH EDITION MANAGER PUBLISHER OBJECTS =========================================== These controls define the RTF controls used to define publisher objects for the Macintosh Edition Manager. The range of publisher objects are marked as bookmarks; therefore, these controls are all used within the \bkmkstart group. The RTF syntax for a publisher object is: {\*\bkmkstart\bkmkpub[\pubauto]{\*\objalias[\bin] <Data>}{\*\objsect[\bin] <Data>} <BookmarkName>} Control Word Meaning ------------ ------- \bkmkpub The bookmark marks a Macintosh Edition Manager publisher object. \pubauto The publisher object will automatically update all Macintosh Edition Manager subscribers of this object whenever it is edited. \objalias This group contains the Alias Record for the publisher object for the Macintosh Edition Manager. If the \bin control is used, the data is in binary format. Otherwise, it is in hexadecimal. \objsect This group contains the Section Record for the publisher object for the Macintosh Edition Manager. If the \bin control is used, the data is in binary format. Otherwise, it is in hexadecimal. DOCUMENT FORMATTING PROPERTIES ============================== This section specifies the attributes of the document, such as margins and footnote placement.

PARAGRAPH FORMATTING PROPERTIES =============================== This group specifies paragraph formatting properties. To ensure compatibility with previous versions of RTF, if border properties are specified, the border segment control word (\brdrt,\brdrb,\brdrl, \brdrr, or \box) must precede the control word(s) that specify the pattern for the border. Paragraph Formatting Control Words -------------------------------------------------------------------- Control Word Meaning ------------ ------- \pard Resets to the default paragraph properties. \s<N> Designates the reference number of the style in the RTF document; if a style is referenced within the document, style properties must be included along with the style reference in the document text. \intbl The paragraph is part of a table. \keep Keep the paragraph intact. \keepn Keep the paragraph with the next paragraph. \noline No line numbering. \pagebb Break the page before the paragraph. \sbys Side-by-side paragraphs.

Spacing -------------------------------------------------------------------- Control Word Meaning ------------ ------- \sb<N> Space before (the default is 0). \sa<N> Space after (the default is 0). \sl<N> Space between lines. If this control word is missing or if \s1000 is used, the line spacing is automatically determined by the tallest character in the line; if <N> is a positive value, this size is used only if it is taller than the tallest character (otherwise, the tallest character determines the size); if <N> is a negative value, the absolute value of <N> determines the size, even if it is shorter than the tallest character. Tabs -------------------------------------------------------------------- Control Word Meaning ------------ ------- \tx<N> The tab position in twips from the left margin. \tqr A flush-right tab. \tqc A centered tab. \tqdec A decimal tab. \tb<N> A bar tab position in twips from the left margin. \tldot Leader dots. \tlhyph Leader hyphens. \tlul A leader underline. \tlth A leader thick line. \tleq A leader equal sign. Paragraph Borders -------------------------------------------------------------------- Control Word Meaning ------------ ------- \brdrt Border top. \brdrb Border bottom. \brdrl Border left. \brdrr Border right. \brdrbtw Consecutive paragraphs with identical border formatting are considered part of a single group with the border information applying to the entire group.

POSITIONED OBJECTS AND FRAMES ============================= The following paragraph-formatting control words specify the location of a paragraph on the page. Consecutive paragraphs with the same frame formatting are considered to be part of the same frame. For two framed paragraphs to appear at the same position on a page, they must be separated by a paragraph with different or no frame information. Control Word Meaning ------------ ------- \absw<N> <N> is the width of the frame in twips. \absh<N> <N> is the height of the frame in twips. A positive number indicates the minimum height of the frame, and a negative number indicates the exact height of the frame. A value of 0 indicates that the height of the frame adjusts to the contents of the frame. Zero is the default for frames where no height is given. Horizontal Position -------------------------------------------------------------------- Control Word Meaning ------------ ------- \phmrg Use the margin as the horizontal reference frame. \phpg Use the page as the horizontal reference frame. \phcol Use the column as the horizontal reference frame. This is the default if no horizontal reference frame is given. \posx<N> Positions the frame <N> twips from the left edge of the reference frame. \posxc Centers the frame horizontally within the reference frame. \posxi Positions the paragraph horizontally inside the reference frame. \posxo Positions the paragraph horizontally outside the reference frame. \posxr Positions the paragraph to the right within the reference frame. \posxl Positions the paragraph to the left within the reference frame. This is the default if no horizontal positioning information is given. Vertical Position -------------------------------------------------------------------- Control Word Meaning ------------ ------- \pvmrg Use the margin as the vertical reference frame. \pvpg Use the page as the vertical reference frame. \pvpara Positions the reference frame vertically relative to the top of the top-left corner of the next unframed paragraph in the RTF stream. This is the default if no vertical frame positioning information is given. \posy<N> Positions the paragraph <N> twips from the top edge of the reference frame. \posyil Positions the paragraph vertically to be in line. \posyt Positions the paragraph at the top of the reference frame. \posyc Centers the paragraph vertically within the reference frame. \posyb Positions the paragraph at the bottom of the reference frame. Text Wrapping -------------------------------------------------------------------- Control Word Meaning ------------ ------- \dxfrtext<N> Distance in twips of a positioned paragraph from the main text flow in all directions. In Word for Windows 2.0, this control affects only the horizontal distance from the text on each side of the frame. \dyfrtext<N> <N> is the vertical distance in twips from the text above and below the frame. The following is an example of absolute-positioned text in a document: A | ... ------------- \par \pard \pvpg\phpg\posxc\posyt\absw5040\dxfrtest173 abs pos para1 \par \pard \phmrg\posxo\posyc\dxfrtext1152 abs pos para2 ------------- | A A: Text to be positioned TABLES ====== There is no RTF table group. A table is a collection of paragraphs, and a table row is a continuous sequence of paragraphs partitioned into cells. The \intbl paragraph formatting control word identifies the paragraph as part of a table. This control is inherited between paragraphs that do not have paragraph properties reset with a \pard. The last paragraph of a cell is terminated by a cell mark (the \cell control word), and the row is terminated by a row mark (the \row control word). The following control words further define the table: Control Word Meaning ------------ ------- \trowd Sets the table row defaults. \trgaph<N> Half the space between the cells of a table row in twips. \cellx<N> Moves the right boundary of a table cell, including its half of the space between cells. \clmgf The first cell in a range of table cells to be merged. \clmrg The contents of the table cell are merged with those of the preceding cell. Cell Borders and Shading -------------------------------------------------------------------- Control Word Meaning ------------ ------- \clbrdrb The bottom table cell border. \clbrdrt The top table cell border. \clbrdrl The left table cell border. \clbrdrr The right table cell border. Row Formatting -------------------------------------------------------------------- Control Word Meaning ------------ ------- \trql Left-justifies a table row with respect to its containing column. \trqr Right-justifies a table row with respect to its containing column. \trqc Centers a table row with respect to its containing column. \trleft<N> The position of the leftmost edge of the table with respect to the left edge of its column. \trrh<N> The height of a table row in twips; when 0, the height is sufficient for all the text in the line; when positive, the height is guaranteed to be at least the specified height; when negative, the absolute value of the height is used, regardless of the height of the text in the line. Cell Shading and Background Pattern -------------------------------------------------------------------- Control Word Meaning ------------ ------- \clshdng<N> <N> is the shading of a table cell in hundredths of a percent. This control should be included in RTF along with cell border information. \clbghoriz Specifies a horizontal background pattern for the cell. \clbgvert Specifies a vertical background pattern for the cell. \clbgfdiag Specifies a forward diagonal background pattern for the cell (\\\\). \clbgbdiag Specifies a backward diagonal background pattern for the cell (////). \clbgcross Specifies a cross-hatched background pattern for the cell. \clbgdcross Specifies a diagonal cross-hatched background pattern for the cell. \clbgdkhor Specifies a dark horizontal background pattern for the cell. \clbgdkvert Specifies a dark vertical background pattern for the cell. \clbgdkfdiag Specifies a dark forward diagonal background pattern for the cell (\\\\). \clbgdkbdiag Specifies a dark backward diagonal background pattern for the cell (////). \clbgdkcross Specifies a dark cross-hatched background pattern for the cell. \clbgdkdcross Specifies a dark diagonal cross-hatched background pattern for the cell. \clcfpat<N> <N> is the line color of the background pattern. \clcbpat<N> <N> is the background color of the background pattern. The following example shows some table text: ... \par \trowd \trqc\trgaph108\trrh280\trleft36 \clbrdrt\brdrth \clbrdrl\brdrth \clbrdrb\brdrdb \clbrdrr\brdrdb \cellx3636\clbrdrt\brdrth ... CHARACTER FORMATTING PROPERTIES =============================== The last group controls character formatting properties. A control word preceding plain text turns on the specified attribute. Some control words (indicated in the following table by an asterisk following the description) can be turned off by the control word followed by 0 (zero). For example, \b turns on bold, whereas \b0 turns off bold. The character formatting control words are listed in the following table: Control Word Meaning ------------ ------- \plain Resets applicationÆs default character formatting properties. \b Turns on bold.* \caps Turns on all uppercase.* \deleted Marks the text as deletion revision marked.* \dn<N> Sets the subscript position in half-points (the default is 6). \expnd<N> Sets the expansion or compression of the space between characters in quarter-points; a negative value compresses the space (the default is 0). \f<N> Identifies the font number. \fs<N> Sets the font size in half-points (the default is 24). \i Turns on italic.* \outl Turns on outline.* \revised Indicates that text has been added since revision marking was turned on. \scaps Turns on small capitals.* \shad Turns on shadow.* \strike Turns on strikethrough. \ul Turns on continuous underline. \ul0 turns off all underlining. \uld Turns on dotted underline. \uldb Turns on double underline. \ulnone Turns off all underlining. \ulw Turns on word underline. \up<N> Sets the superscript position in half-points (the default is 6). \v Turns on hidden text.* \lang<N> Applies a language to a character. <N> is a number corresponding to a language. The following table defines the standard languages used by Microsoft. This table was generated by the Unicode group for use with TrueType(R) and Unicode. A \plain control resets the language property to the language defined by \deflang<N> in the document properties. Language Name Language ID ------------- ----------- No Language 0x0400 Albanian 0x041c Arabic 0x0401 Bahasa 0x0421 Belgian Dutch 0x0813 Belgian French 0x080c Brazilian Portuguese 0x0416 Bulgarian 0x0402 Catalan 0x0403 Croato-Serbian (Latin) 0x041a Czech 0x0405 Danish 0x0406 Dutch 0x0413 English (Aus.) 0x0c09 English (U.K.) 0x0809 English (U.S.) 0x0409 Finnish 0x040b French 0x040c French (Canadian) 0x0c0c German 0x0407 Greek 0x0408 Hebrew 0x040d Hungarian 0x040e Icelandic 0x040f Italian 0x0410 Japanese 0x0411 Korean 0x0412 Norwegian (Bokmal) 0x0414 Norwegian (Nynorsk) 0x0814 Polish 0x0415 Portuguese 0x0816 Rhaeto-Romanic 0x0417 Romanian 0x0418 Russian 0x0419 Serbo-Croatian (Cyrillic) 0x081a Simplified Chinese 0x0804 Slovak 0x041b Spanish (Castilian) 0x040a Spanish (Mexican) 0x080a Swedish 0x041d Swiss French 0x100c Swiss German 0x0807 Swiss Italian 0x0810 Thai 0x041e Traditional Chinese 0x0404 Turkish 0x041f Urdu 0x0420 To read negative \expnd values from Word for the Macintosh, an RTF reader should use only the low-order 6 bits of the value read. Word for the Macintosh does not emit negative values for \expnd. Instead, it treats values from 57 through 63 as -7 through -1, respectively (the low-order 6 bits of 57 through 63 are the same as -7 through 1). SPECIAL CHARACTERS ================== The RTF standard includes control words for special characters. If a special character control word is not recognized by the RTF reader, the control word is ignored, and the text following it is considered plain text. The RTF specification is flexible enough to allow new special characters to be added for interchange with other software. The special RTF characters are listed in the following table: Control Word Meaning ------------ ------- \chdate The current date (as in headers). \chdpl The current date in long format; for example, Tuesday, June 28, 1992. \chdpa The current date in abbreviated format; for example, Tue, Jun 28, 1992. \chtime The current time (as in headers). \chpgn The current page number (as in headers). \chftn An automatic footnote reference (the footnotes follow in a group). \chatn An annotation reference (the annotation text follows in a group). \chftnsep An anchoring character for the footnote separator. \chftnsepc An anchoring character for the footnote continuation. \cell The end of a table cell. \row The end of a table row. \par The end of a paragraph. \sect The end of a section and a paragraph. \page A required page break. \column A required column break. \line A required line break (no paragraph break). \tab A tab character; the same as ASCII 9. \emdash An em (--) dash. This is character 151 in the ANSI character set and character 208 in the Macintosh character set. \endash An en (-) dash. This is character 150 in the ANSI character set and character 209 in the Macintosh character set. \bullet A bullet character. This is character 149 in the ANSI character set and character 165 in the Macintosh character set. \lquote An opening single quotation mark. This is character 145 in the ANSI character set and character 212 in the Macintosh character set. \rquote A closing single quotation mark. This is character 146 in the ANSI character set and character 213 in the Macintosh character set. \ldblquote An opening double quotation mark. This is character 147 in the ANSI character set and character 210 in the Macintosh character set. \rdblquote A closing double quotation mark. This is character 148 in the ANSI character set and character 211 in the Macintosh character set. \| A formula character. \~ A nonbreaking space. \- An optional hyphen. \_ A nonbreaking hyphen. \: Specifies a subentry in an index entry. \* Marks a destination whose text should be ignored if not understood by the RTF reader. \'hh A hexadecimal value, based on the specified character set (may be used to identify 8-bit values). \alt The ALT modifier key. Used to describe shortcut-key codes for styles. \shift The SHIFT modifier key. Used to describe shortcut- key codes for styles. \ctrl The CTRL modifier key. Used to describe shortcut-key codes for styles. Specifies a function key where <N> is the function key number. Used to describe shortcut-key codes for styles. NOTE: An ASCII 9 is accepted as a tab character. A carriage return (character value 13) or linefeed character (character value 10) will be treated as a \par control if the character is preceded by a backslash. You must include the backslash, or RTF ignores the control word. (You may also want to insert a carriage- return/linefeed pair without backslashes at least every 255 characters for better text transmission over communication lines.)
