Apple II File Type Notes _____________________________________________________________________________ Developer Technical Support File Type: $54 (84) Auxiliary Type: $DD3E Full Name: Medley Desktop Publishing Document Short Name: Medley Document Written by: Matt Deatherage & Eric Soldan May 1989 Files of this type and auxiliary type contain documents for Medley(TM). _____________________________________________________________________________ Medley is a WYSIWYG application that integrates word processing, paint, and page layout programs, with the addition of a spelling checker and thesaurus. The page layout function supports various shapes for art and text areas. Text automatically wraps around or within these areas, including irregularly shaped regions. The word processor is full-featured, as is the paint program. The dictionary has 80,000 words. For more information on Medley, contact: Milliken Publishing Company 1100 Research Blvd. St. Louis, MO 63132 Attention: Medley Technical Support (314) 991-4220 The Medley file format is copyrighted (C) 1988 by Milliken Publishing Company and is printed here with permission. Definitions The following definition is used in this document in addition to those defined for all Apple II file types: C String A series of ASCII bytes terminated with a byte of $00. There is no count byte at the beginning, as is the case for the String type (also referred to as a "Pascal string"). File Structure Medley files are basically standard, single-linked tree structures. There is a single object at the top of the tree, and other objects may branch off this parent object. Each child object is linked to the parent by a pointer to the child contained within the parent object. A non-standard thing about the Medley tree structure is that some objects may have regions or polygons associated with them. The handles to these objects are stored in the parent object when in memory, but on disk these handles are quite meaningless. Because of this difference, the regions or polygons are simply appended to the parent object itself when written to disk. The size of the region or polygon is added to the size of the parent object, giving an aggregate size for the complex object on disk. The file is written to disk in an order based on a simple tree-walking algorithm. This algorithm starts with the highest parent object and writes it to disk. The parent object is checked for child objects. If one exists, it is written to disk, and then it is checked for child objects. This tree- walking continues until an object runs out of children. When that occurs, Medley backs up one tree level, writes the next child object to disk, and scans it for children. This method continues until all objects are written to disk. For example, if a parent object named A had two child objects named B and C, where B had children E and F, and C had children G and H, the objects would be written to disk in the following order: A, B, D, E, C, F, G. Figure 1 illustrates this structure. _________ | | | A | |_________| |---------------|---------------| ____|____ ____|____ | | | | | B | | C | |_________| |_________| |-------|-------|---------------|-------|-------| ____|____ ____|____ ____|____ ____|____ | | | | | | | | | D | | E | | F | | G | |_________| |_________| |_________| |_________| Figure 1-Example of Parent and Child Tree Structure Some Medley objects, when in memory, have handles to other objects (such as regions or polygons) in them. Since handles are meaningless on disk, Medley stores these complex objects in an aggregate form by writing the contents of each associated handle to disk following the regular object. The Objects and Their Formats All objects have a common 13-byte header, which is as follows: type (+000) Byte The type of the object. Possible values are: 0 = Null Object (never saved to disk) 1 = Root Object (never saved to disk) 2 = File Object 3 = Page Object 4 = Paragraph Object 5 = Area Object 6 = Art Object 10 = Document Dictionary Object. Objects 7, 8 and 9 are for posting undo events. Since these are not saved to disk, they are irrelevant for the file format. numChildren (+001) Word The number of children for this object. Children of the children are not included. endData (+003) Long The size of this object on the disk, not counting associated handles (such as regions and polygons). reserved (+007) Long Reserved; set to zero when creating files. objRefNum (+011) Word The reference number of this object, generally zero. Each object has the header listed above followed by object-specific data. For this reason, the description of each object will start with offset +013 (the byte following the header). The File Object rect (+013) 4 Words Standard QuickDraw II rectangle, giving the boundary rectangle for the entire file. pathName (+021) 129 Bytes Class zero pathname for the file on disk (used by the save command). saved (+150) Byte This byte is 1 if no changes have been made to the file since the last save. windowPtr (+151) Long Pointer to the window for this file. When creating files, set to zero. wndwNameIndx (+155) Byte Index into table of window names. Set to zero when creating files windowOrigin (+156) 2 Words QuickDraw II point representing the global origin of this file's window. windowSize.h (+160) Word Height of window in pixels. Add to top edge of window to get bottom edge of window. windowSize.v (+162) Word Height of window in pixels. Add to left of window to get right edge of window. COrigin (+164) Long QuickDraw II point representing the scroll bar origin of this file's window. When creating files, set this to whatever origin you wish Medley to display. Make sure that the coordinate is valid. editHndl (+168) Long Handle to the paragraph containing the cursor. This is converted to a child number on disk, since handles on disk are meaningless. editOffset (+172) Word Offset to the cursor within the paragraph pointed to by editHndl. cursor (+174) 4 Words Standard QuickDraw II rectangle, giving the rectangle used for the insert cursor. This can be set to a null rectangle when creating files, and will be calculated when the file is loaded. showAllBorders (+182) Byte If this is set to one, then all area borders will display, regardless of each area's border display setting. updateRect (+183) 4 Words Standard QuickDraw II rectangle used for posting specific updates for the interruptible word processor. When creating files, set this to a null rectangle. topMrgn (+191) Fixed The top margin in inches. bottomMrgn (+195) Fixed The bottom margin in inches. leftMrgn (+199) Fixed The left margin in inches. rightMrgn (+203) Fixed The right margin in inches. gutterMrgn (+207) Fixed The gutter margin in inches. pageWidth (+211) Fixed The width of the page in inches. pageHeight (+215) Fixed The height of the page in inches. selectPage (+219) Word The active page for area editing. numSelected (+221) Word The number of areas currently selected by the user. sizingDot (+223) Word The sizing dot number of an area that was last clicked. This sizing dot will be used as the current sizing dot when the arrows are used to size an area. effectivePage (+225) Word The page number of the page the user was effectively editing. This is different from selectPage when the user was editing global areas at save time, for global areas are treated as on page zero. printRecord (+227) 140 Bytes A standard IIGS Print Manager print record; the one in use for this document at save time. This field can be undefined, if the printRecordDefined field is zero. interruptMode (+367) Word Currently undocumented. (Set to zero.) editScroll (+369) Byte Currently undocumented. (Set to zero.) firstHndl (+370) Long Handle where wrap-around regions should actually start; i.e., where an update is needed. When creating files, set this to zero. firstMrn (+374) Word MiniRect number (line number of paragraph) where wrap-around regions should actually start; i.e., where an update is needed. When creating files, set this to zero. selectMode (+376) Word Some text is selected if this is 1. Each paragraph will indicate the range of characters selected within that paragraph. This allows the screen update routine to quickly determine which characters in a paragraph should be drawn selected. showPgphMarks (+378) Byte Indicates whether paragraph marks are currently being shown. showSpaces (+379) Byte Indicates whether spaces are shown with marks and tabs are shown with arrows. showMoveChangeInfo (+380) Byte Indicates whether the Move/Change window is active. moveChangeInfoRect (+381) 4 Words Standard QuickDraw II Rectangle giving the position of the Move/Change window. addNewUndo (+389) Byte Currently undocumented. revNum (+390) Word Revision number of the version of Medley that created this file. For files created following this standard, use $0100 (for Medley 2.0). showRulers (+392) Byte Indicates whether the rulers are showing. windowType (+393) Word The type of window this is. 0 = document, 1 = clipboard. When creating files, set this to zero. auxDictPath (+395) 129 Bytes Class zero GS/OS pathname to the auxiliary dictionary file for this document. When creating files, set this to a null pathname (a length byte of zero). grayScale (+524) Word Whether or not grayScale mode is active. Zero for color, one for grayScale. printRecordDefined (+526) Word Non-zero if a print record is defined. This is used because the Printer and Port drivers must be loaded before calling PrDefault or PrValidate, and that means the boot disk must be on line. If Medley knows the print record is good, it proceeds without calling the Print Manager. evenPageNumText (+528) 48 Bytes The text for even-numbered pages to be displayed by the page number. oddPageNumText (+576) 48 Bytes The text for odd-numbered pages to be displayed by the page number. pageNumInfo (+624) 32 Words A word for each of the pages possible in the file, through the absolute maximum of thirty-two. affectPageRange(+688) 2 Bytes The range of pages affected by the Medley "Change Page Numbers" command. The first byte is the beginning page; the second byte is the ending page. pageNumFont (+690) 4 Bytes A Font Manager FontID, identifying the font used for the page numbers. This is a two-byte font family number, followed by a one-byte font style and one-byte font size. startPageNum (+694) Word The page number of the first page. This is a zero-based counter; page one is represented as zero. offsetFromEdge (+696) Word The distance in points that the page numbering text appears from the edge of the paper. Note: The following three fields are in Medley 2.0 files, but do not exist in Medley 1.0 files. If you are reading a 1.0 file, the value of revNum will be $0000. If reading a 1.0 File Object, resize it to 2.0 size (including the three fields below) and initialize their values to the values given below. maxNumPages (+698) Word The maximum number of pages in this document. When creating new files, initialize this to 32 ($20) unless condensed (below) is non- zero. If condensed is non-zero, you really have to hurt yourself to get this field right. Below is the algorithm Medley uses to calculate this field (in something close but not exactly related to pseudo-code). Please recall that all variables relating to the margins (taken from the file object) are Fixed. workHeight := topMrgn + bottomMrgn if [condensed is non-zero] then workHeight := workHeight * 2 workHeight := pageHeight - workHeight workHeight := workHeight * [pixels per vertical inch] workHeight := workHeight + $0000FFFF [this counts a fractional point as a whole point] i := HiWord(workHeight) [this gives the integer portion] i := i + 3 [accounts for 3-pixel page breaks] i := (16384 - 208) / i [gives number of pages in conceptual drawing space. Since Medley allows 48-point characters plus leading, the tallest a text rectangle may be is 208 pixels. Text that does not fit in maxNumPages is kept around in a non- displayable, non-editable, non-printable page. Any shortening of the document will cause some or all of the previously non- displayed text to flow up into the document.] i := min(32,i) [32 is the absolute maximum number of pages Medley allows due to QuickDraw's conceptual drawing space limitations.] maxNumPages := i condensed (+700) Word Indicates whether the document is designed to use condensed printing. If non-zero, the document is designed to use condensed printing. When creating files, it is easiest not to deal with condensed printing, so set this field to zero. However, if you wish to create a document that Medley may edit and print as condensed, you must correctly relate this field to the previous one by the algorithm given above. reserved (+702) 6 Bytes These six bytes should be set to zero. The Page Object Pages are the first-level children of files. There is one page object for each page in a document (file object). rect (+013) 4 Words Standard QuickDraw II rectangle giving the boundary rectangle for this page. wrapDir (+021) Byte The direction of word-wrapping. 1 = Down, 2 = across. rgn (+022) Long Handle to the region for this page in memory. The region is the page rectangle less any areas on that page. Global areas are not subtracted from this region. They are subtracted from the page rectangle for the global page (page zero). On disk, where the page region would be written, you can write a 10, followed by the rectangle for the page. This is a rectangular region. The aggregate size of the page object on disk must include these 10 bytes. This is assuming, of course, that there are no areas on that page to make the page region non-rectangular. hideGlobalArt (+026) Byte A non-zero value indicates that global art is not displayed on this page. hideGlobalPageParts (+027) Byte A non-zero value indicates that global page parts are not displayed on this page. The Paragraph Object Paragraphs are the children of the file object; they are not the children of page objects since a paragraph may be seen on more than one page or page part. Paragraph objects are, however, stored on disk immediately following page objects and their children. Paragraph objects are first-level objects also. wrapHere (+013) Word Insertion offset point in paragraph data where wrapping should continue. For wrapping from beginning of paragraph, set this field to zero. fullWrap (+015) Word Same as wrapHere, but indicates at what point miniRect construction or reconstruction must continue. Again, for full-wrapping of a paragraph, set to zero. rulerOffset (+017) Word Offset in bytes from beginning of paragraph object to indicate where the ruler starts. (The ruler is just before the character data, just after the miniRects.) If there is no ruler, then the default ruler is used by Medley. (If the dataOffset value is the same as the rulerOffset, then there is no ruler, and the default ruler will be used.) The default ruler has tabs at each 1/2 inch mark, no indent or paragraph indent, and the right margin is at maximum. dataOffset (+019) Word Offset in bytes from beginning of paragraph object to indicate where character data starts. If there are no miniRects built yet (probable if file is being created outside Medley) and there is no ruler, then this value will be a 32. numRects (+021) Word The number of discrete text rectangles in this paragraph. When creating a file, set fullWrap to zero, and numRects to zero, and place your character data starting at byte 32 of a paragraph object, and the rectangles will be built when the file is loaded by Medley as wrap occurs. begInvOffset (+023) Word Offset from the beginning of the character data where inverse text starts in this paragraph. endInvOffset (+025) Word Offset from the beginning of the character data where inverse text ends in this paragraph. topLeading (+027) Byte The number of pixels leading above each line in this paragraph. botLeading (+028) Byte The number of pixels leading below each line in this paragraphs. begPgphGap (+029) Byte The number of pixels extra leading above this paragraph. endPgphGap (+030) Byte The number of pixels extra leading below this paragraph. flags (+031) Flag Byte Bits 0 and 1 are used to indicate justify mode. 00 = left justify. 01 = right justify. 10 = center justify. 11 = full justify. Bit 7 indicates a page-break after this paragraph. miniRects (+032) MiniRects Any miniRects, if any, are contained here. The number of miniRects is given by numRects above. MiniRects have the following format: miniRect.rect (+000) 4 Words Standard QuickDraw II rectangle that is calculated by the wordWrap routine to bound a line of text. mr.begOffset (+008) Word Offset from start of character data to the first character this miniRect bounds. mr.endOffset (+010) Word Offset from start of character data to just past the last character this miniRect bounds. A Ruler in the document will be after the miniRects, if there are any. The offset to the Ruler is given by rulerOffset. Rulers are formatted as follows: leftPgphMrgn (+000) Byte The left margin for this paragraph, in sixteenths of an inch. rightPgphMrgn (+001) Byte The right margin for this paragraph, in sixteenths of an inch. This is an offset from the default right margin from Medley's "Set margins" command. For example, the value 16 represents a right margin one inch to the left of the default right margin. pgphIndent (+002) Byte The indentation for this paragraph, in sixteenths of an inch. numTabs (+003) Byte The number of tabs in this ruler. tabs (+004) Tabs There are numTabs of these. Tabs are formatted as follows: tab Flag Word Tabs consist of a high byte of flags and low byte of position. The bits are assigned as follows: Bits 15-12 = Reserved; set to zero. Bits 11-10 = Tab Leader style: 00 = No leader 01 = Leader of dots (.......) 10 = Leader of dashes ( - - ) 11 = Solid Leader (_________) Bits 9-8 = Tab Type: 00 = Left Tab 01 = Right Tab 10 = Center Tab 11 = Decimal Tab Bits 7-0 = Byte value; the position of this tab as an offset from the left margin in sixteenths of an inch. A value of sixteen indicates a tab one inch to the right of the left margin. Following miniRects and rulers is the actual character data for this paragraph. This is all Bytes. However, a Byte value of $01 through $07 indicates the beginning of a Font Escape. Font Escapes indicate changes in style or size of the text, and are formatted as follows: FontEscape (+000) Byte An indication of the type of text the following fontID affects: 1 = Regular Text 2 = Superscript Text 3 = Subscript Text 4-7 = Reserved; do not use fontID (+001) 4 Bytes A Font Manager FontID, identifying the font used for the page numbers. This is a two-byte font family number, followed by a one-byte font style and one-byte font size. The text portion of a paragraph always begins with a Font Escape and ends with the end-of-paragraph character Byte $A6. This makes the minimum size of a paragraph (assuming no miniRects or rulers) thirty-eight bytes (32 bytes for the Paragraph Object, five bytes for the Font Escape and one byte for the $A6). The Area Object Area Objects are the children of pages or paragraphs. type (+013) Byte The type of area this area object describes. Possible values are: 0 = Null Area 1 = Group Area 2 = Rectangular Area 3 = Round Rectangular Area 4 = Oval Area 5 = Polygon Area select (+014) Byte This value is one if this area is selected. showBorder (+015) Byte This value is one if the border of this area is showing. contentType (+016) Byte 0 = Art, 1 = Wrap Down, 2 = Wrap Across. rgn (+017) Long Handle to the region that describes the shape of this area. On disk, this region is at the end of this object (see the Reading The File section of this Note). interiorRgn (+021) Long Handle to the regions that describes the interior of this area. On disk, this region is at the end of this object (see the Reading The File section of this Note). sizingRgn (+025) Long Handle that contains all the sizing dots. It is too slow to draw them one at a time. Also, detecting that the user clicked in a sizing dot can be done quickly -- just not which one. flags (+029) Word Only bit zero of this word is significant; if set it indicates this area should be printed to LaserWriters in gray-scale. All other bits of this word should be zero. reserved (+031) Word Reserved for Milliken. Set to zero. At this point is the description of the area itself. This description varies on the type field above: For rectangles (type = 2): rect (+033) 4 Words Standard QuickDraw II rectangle describing the rectangle for this area. For round rectangle (type = 3): rect (+033) 4 Words Standard QuickDraw II rectangle describing the boundary rectangle for the round rect. height (+041) Word The height of the oval portion of the rectangle. width (+043) Word The width of the oval portion of the rectangle. For ovals (type = 4): oval (+033) 4 Words A standard QuickDraw II rectangle describing the bounding rectangle for this oval. The oval drawn is the ellipse inscribed in this rectangle. For Polygons (type = 5): polygon (+033) Bytes A handle to a QuickDraw II polygon. This handle may be passed to QD Polygon routines. On disk, this polygon is appended to the end of this object (see the Reading The File section on this Note). These objects are the last items in the area object. The Art Object Art Objects are the children of pages, paragraphs or areas. BBox (+013) 4 Words A standard QuickDraw II rectangle representing the bounding box of this art object. offsetFromRgn (+021) 2 Words Normally zero. The area containing an art image can be grown and shrunk. The art within it is not clipped to the bounding rectangle of the area until the user deselects the area. (If it is saved to disk while selected, then it is saved unclipped). This allows the user to experiment with different shapes without clipping the drawing within. If the drawing is to the left of the left edge of the area, or is above the top edge, then this offset indicates by how much. artImage (+025) Bytes The actual bitmap of the art image. The Document Dictionary Object The Document Dictionary Object is the very last child of the file object, and contains all the words the spelling checker should ignore even though they are not in the main dictionary. count (+013) Word The number of word entries in this dictionary object. wordList (+015) Word Entries List of dictionary word entries. The format of word entries is as follows: recordLength (+000) Byte The length of this record. replaceFlag (+001) Byte Reserved, set to zero. newWord (+002) C String The word in question. This word should be counted as spelled correctly, and is not in the Main or Auxiliary Dictionary. The length of a record is the length of string plus three bytes (one for recordLength, one for replaceFlag, and a zero termination byte). Reading the File When reading a Medley file, objects with regions or polygons will have to be treated specially, since the handles in the objects are invalid and the regions or polygons actually follow the object in the disk file. A sequence for reconstructing Medley files in memory is as follows: 1. Open the file, or set the mark to zero on an open file. 2. Start with a handle that is 13 ($0D) bytes long. Pass this handle to the routine starting in step three. 3. Save the handle passed to this routine, and read four bytes from disk. This Long is the total size of an object, including any regions or polygons appended. 4. Read the 13-byte object header into the handle passed to this routine. The endData field of the header gives the size of the object, minus any associated regions or polygons. Resize the object's handle (the handle passed to you) to this size. 5. Read the rest of the object (endData - 13 bytes) into the object's handle. 6. Save the value of numChildren in a local variable and set the numChildren field in the object header to zero. The field in the header represents the number of children read from disk; setting this to zero properly indicates that you haven't read any of the children yet. 7. Look at the object type field. If the object is a file, area, or page object, it may have a region associated with it. If the object is an area object, it may also have a polygon associated with it (if the area type field indicates this is so). You can tell if the object has any appended structures by comparing the total object size (read in step three) with the endData field (read in step four); if an object has no appended structures, the two values will be the same. If there are structures appended to the object, first zero all the handles to the regions inside the object. This allows elegant error recovery if an error occurs while reading the region or polygon. When the handles are zeroed, read the next two bytes from the disk. This Word is the size of the region or polygon in bytes. Create a handle of that size, place it in the object's field for this handle, and place the size Word in the first two bytes of the new handle. Now read the object from disk into the new handle starting at the beginning +002 (past the size Word). Continue in this fashion until all appended regions or polygons have been read from disk. Any appended structures will be stored in the same order as their handles occur in the object. Note: By zeroing the handles before reading the objects, you can return from this function with an error, and the calling routine will be able to dispose of all handles that were actually created. The calling routine will know if a handle was actually created or not by examining the handle field in the object; NIL handles were not created. 8. Execute a loop for the old number of children (0 to oldNumChildren-1): 9. Create an object that is 13 ($0D) bytes long. Add this handle to the end of the parent object that was last read. Increment the number of children. You have just added a child into the child table for an object. 10. Call the recursive subroutine beginning in step three, passing it the handle you just created. If it returns an error, return the error. This gets you out of the recursion with the correct error, no matter how many levels deep you are. 11. Keep looping until out of children to read. The EOF condition does not have to be checked, since you will run out of children when you reach the end of the file. If an EOF is reached before you read all the children, you did something wrong. 12. Return no error--the file was successfully read. 13. When done with all this, you will return to the code just beyond step two, where you first called the recursive subroutine at step three. If an error is returned, dispose of all the handles created by the recursive function. Even if the file read is aborted, the tree is complete for as much as was read. (This is why the numChildren field is incremented as you read the file.) An alternate way to handle this is to use a different userID for the handles created when reading the file; this allows you to dispose of all of them with one DisposeAll call. 14. Close the file if you opened it, or reset the mark to its previous position if it was already open. The entire file does not have to be read from disk. By using the size field, you can skip to the next object in the file. Using this technique, you can scan the file for whatever it is that interests you. Note: You may have noticed that objects successfully created in memory will have a table of handles to children at the end. Objects on disk will not have these handles, since the handles on disk are meaningless. The child handle table is reconstructed as the file is loaded into memory. Object Ordering The file object is the first you will encounter in a Medley file. Its children are ordered as follows: Page Object--Page #0. This is the global page object, containing all global areas. Page Object--Page #1. This is the page object for page #1; it must exist.
