         18.6. TYPESETTING CODES

           Typesetting codes can be embedded in a text block to
         change its text parameters "locally." For example, the font
         of a single word or phrase can be changed (perhaps to
         italic) without exiting the editor. A typesetting code
         consists of a filled-in less-than character (signifying
         "turn on the code," and obtained by pressing Ctrl A or Ctrl
         a), followed by some letters and numbers (the code itself),
         and ending with a filled-in greater-than character
         (signifying "turn off the code," and obtained by pressing
         Ctrl Z or Ctrl z). For example, if the text block you are
         editing has a point size of 20 and you want to write "x
         subscript 1 + y superscript 2," you might type the
         following: "x" Ctrl A "PS10" Ctrl Z Ctrl A "DP6" Ctrl Z "1"
         Ctrl A "PS20" Ctrl Z Ctrl A "UP6" " + y" Ctrl A "PS10" Ctrl
         Z Ctrl A "UP12" Ctrl Z "2" Ctrl A "PS20" Ctrl Z Ctrl A
         "DP12" Ctrl Z (where Ctrl A can be replaced by Ctrl a and
         Ctrl Z can be replaced by Ctrl z). Key this into the editor
         to see: x<PS10><DP6>1<PS20><UP6> +
         y<PS10><UP12>2<PS20><DP12> (well, almost -- the less-than
         and greater-than characters are FILLED IN SOLID in the
         editor). (Note that there is an automatic subscript and
         superscript feature that makes this operation much easier.)
           What do the codes do? See the table below.

         CODE           MEANING
         <PSnnn>        Change current text point size to nnn = 1 to
                          999

         <FTnnnn>       Change current font number to nnnn = 1 to 9999

         <LSnnn.n>      Change current line spacing (in points) to

         <GRnnn>        Change current text gray percentage to nnn = 0
                          to 100

         <PCnnn>        Change current text point size to nnn times
                          previous text point size (rounding to
                          nearest point) (nnn = .1 to 100)

         <FPnnn>        Move forward nnn points (nnn = 1 to 999)

                          subsequent go to

         <GOn>          Go to position n (= 0 to 9) previously marked
                          and insert the following text

         <GOX>          End text to be inserted with go to; text
                          following this code begins at the position
                          just before the <GOn>; <GOX> isn't needed if
                          all of the text following <GOn>, to the end
                          of the text block, is to be inserted

         <TK[+][-]nnn>  Turn on track kerning with spacing between all
                          character pairs reduced (if nnn is negative)
                          or increased (if nnn is positive; the + sign
                          is optional) by nnn units, with nnn = -999
                          to 999

         <TKX>          Turn off track kerning

         <PKO>          Turn on pair-wise kerning

         <PKX>          Turn off pair-wise kerning

         <SBO>          Turn on subscripting with default settings for
                          subscript character size and baseline
                          positioning (that is, settings in the
                          current font's width information file,
                          which can be altered by using the utility
                          program MODFONT.EXE (see Section 18.10))

         <SBmmm,nnn>    Turn on subscripting with subscript character
                          point size mmm% of current character point
                          size (mmm = 1 to 100), and with subscript
                          character baseline position nnn% of current
                          character point size below current baseline
                          position (nnn = 0 to 100)

         <SBX>          Turn off subscripting

         <SPO>          Turn on superscripting with default settings
                          for superscript character size and baseline
                          positioning (that is, settings in the
                          current font's width information file,
                          which can be altered by using the utility
                          program MODFONT.EXE (see Section 18.10)

                                        68

         <SPmmm,nnn>    Turn on superscripting with subscript
                          character point size mmm% of current
                          character point size (mmm = 1 to 100), and
                          with superscript character baseline position
                          nnn% of current character point size above
                          current baseline position (nnn = 0 to 100)

         <SPX>          Turn off superscripting

         <HYO>          Turn on automatic hyphenation

         <HYX>          Turn off automatic hyphenation

           Note: In each case, the code letters can be upper (as
         shown) OR lower case.
           Note: If text to be inserted with a go to code is not
         ended with <GOX> before a carriage return or a wrap, the
         results are unpredictable, and marks within go to text don't
         always work correctly, especially if the justification is
         full, right, or centered.
           Note: Subscripts and superscripts can be nested to several
         levels.
           To make repeated use of some codes easier, and to
         facilitate the use of keyboard macro programs for
         "automated" input of text, the following codes also can be
         used:

         CODE           MEANING

         <PSD>          Use current text block's default point size
                          (that is, the point size specified when the
                          editor was entered)

         <PSP>          Use immediately previous point size

         <FTD>          Use current text block's default font number
                          (that is, the font number specified when the
                          editor was entered)

         <FTP>          Use immediately previous font number

         <LSD>          Use current text block's default line spacing
                          (that is, the line spacing specified when
                          the editor was entered)

         <GRD>          Use current text block's default text gray
                          percentage (that is, the text gray
                          percentage specified when the editor was
                          entered)

         <TKD>          Set track kerning to 0

         <TKP>          Turn on track kerning and use immediately
                          previous setting (= 0 if not set previously)

         <SBD>          Turn on subscripting and use default settings
                          of current font

         <SPD>          Turn on superscripting and use default
                          settings of current font

                                        69

           No doubt you're still wondering what the codes REALLY
         do... and what "units" are. Look again at the "x subscript 1
         + y superscript 2" example above. Initially, the text point
         size is 20, so the "x" is a 20-point character. Then <PS10>
         changes the point size to 10, and <DP6> moves down 6 points,
         so the "1" is a 10-point character (smaller than the "x," as
         a subscript should be) placed with its baseline 6 points
         lower than the baseline of the "x" (also as a subscript
         should be). The <PS20> and <UP6> codes restore the initial
         settings so that the " + y" has the same baseline and point
         size as the "x." And similarly for the (superscript) "2."
           You can use typesetting codes to change fonts for only a
         few characters (allowing italicized phrases and special
         symbols, for example), to make a few characters gray, to
         change the spacing between certain lines, etc., etc. If you
         use PictureThis much, you'll probably soon become proficient
         at using the codes.
           Now, what are "units"? They allow us to measure distances
         RELATIVE TO THE CURRENT TEXT POINT SIZE: for PictureThis,
         there are 1000 units per em width. In typesetting, a dash or
         hyphen which is as wide as the text point size is known as
         an emdash. So an emdash for 10-point text is 10 points wide,
         and an emdash for 30-point text is 30 points wide. (An
         aside: typically, most fonts have capital letters which are
         about two-thirds as tall as their point sizes, so an "A" in
         a 100-point font is likely to be around 60 to 70 points
         tall. That gives you an idea of how big characters REALLY
         are when their font has a certain point size, even though
         some fonts have characters "large" for their point size, and
         others have characters "small" for their point size)
           By extension from the emdash, the em width of a font is
         equal to the font's point size. So, for a 10-point
         PostScript font used in PictureThis, there are 100 units per
         point (1000 units per em width divided by 10 points per em
         width); for a 30-point PostScript font, there are about 33
         units per point (1000 units per em width divided by 30
         points per em width); for a 100-point PostScript font, there
         are 10 units per point; for a 300-point PostScript font,
         there are about 3 units per point; and for a 1000-point
         PostScript font, there is 1 unit per point. In other words,
         the ABSOLUTE size of a unit is PROPORTIONAL to the current
         text point size. One unit for a 100-point font is 10 times
         as big (as measured in points, inches, centimeters, etc.) as
         one unit for a 10-point font.
           The proportional relationship between units and text point
         size is useful for positioning characters relative to one
         another "the same way" (proportionally!) REGARDLESS OF TEXT
         POINT SIZE -- just use units instead of points in the
         typesetting codes used for the positioning. For example,
         suppose you want to set a "P" followed by a 3-point space
         and then a "T" at a 10-point text size. One way to do this
         is to key in "P" Ctrl A "FP3" Ctrl Z "T" in the editor.
         That's fine if you need ONLY 10-point text. But what if you
         also want the same output at, say, 20 points? (Yes, you
         could scale the PostScript output, or you could scale the
         text block as an object (as described in Section 17.3) but
         we're concerned only with the editing operations here.) You
         could change the point size to 20 and key in "FP6" instead
         "FP3," but you also could have BEGUN (at the 10-point size)
         by keying in "FU300" instead of "FP3," and then, just by

                                        70

         changing the text point size to 20, you would get what you
         wanted at the bigger size (because for the 10-point font,
         there are 100 units per point, and <FU300> means "move
         forward 3 points," while for the 20-point font, there are 50
         units per point, and <FU300> means "move forward 6 points").
           Units also are convenient because of their small size
         relative to text point size, allowing extremely fine
         adjustments in character placement.

         18.7. SCREEN FONTS

           Consider the characters as represented on the drawing
         screen when you set a text block by pressing F5. The default
         setting for how the characters are shown is "text," meaning
         that each character on the drawing, view, and Quickshow
         screens is shown using a screen font: an APPROXIMATION to
         the actual PostScript output; however, the POSITION and
         WIDTH of each character, if not always its FORM, are shown
         quite accurately. PictureThis Release 4 screen fonts are
         vector-mapped, not bit-mapped, so they can be scaled as
         needed.
           To change the setting for how characters are shown, press
         J (mnemonic: "jabber"), which cycles among the following
         settings: "text" on drawing, view, and Quickshow screens
         (the default, as described above); "greeked" (text
         represented by dotted ascender lines (showing the height of
         h's and k's) and baselines) on drawing, view, and quickshow
         screens; and "greeked" on drawing and view screens, but
         "text" on the Quickshow screen. Drawing is slower with the
         "text" setting than with the "greeked" setting, but, of
         course, the former provides more information. When you are
         doing a full text page, especially for a small point size
         text and especially when viewing on the 50% screen (which is
         the only screen on which you can see a full 8-1/2 by 11
         page), we recommend using the "greeked" setting since it is
         much faster and you can't read the small text anyway. (It
         also uses much less pixel memory - see Section 31.) In such
         a case, view the "text" only on the Quickshow screen, or
         when you need a closeup of a section of a page.
           Standard-encoding PostScript fonts (those sometimes
         referred to as having an "International" character set)
         shown with the "text" (screen font) setting all are
         represented with the same simple "block character" screen
         font (adjusted, of course, to show correct character
         widths), and that screen font is SLANTED (at 10 degrees,
         unless the font has been slanted with the MODFONT.EXE
         utility program, as described in Section 18.10) for italic
         fonts and DOUBLE-WRITTEN for bold fonts.
           With the "text" setting, if the appropriate screen font
         files (STANDARD.SFT, SYMBOL.SFT, and/or ZAPFDB.SFT) cannot
         be accessed by PictureThis or do not fit in available
         memory, characters are represented as boxes; each box
         extends from the baseline to the ascender height (actually,
         an APPROXIMATE ascender height for the Symbol and
         ZapfDingbat fonts, since their AFM files don't provide
         "official" ascender heights) and has the width of its
         character. Boxes also are used in screen fonts when a
         character has a valid width (in the font's width file), but
         there is no corresponding screen character in the screen
         font file (an example is given by the Symbol font, in which

                                        71

         the character associated with Alt 240 prints as a
         (trademark) apple-with-a-bite-out-of-it on a few PostScript
         printers (you can guess which ones!), but as NOTHING on
         other PostScript printers; the Symbol font width information
         file FONT81.FIN on one of the PictureThis distribution disks
         includes a width for the character, since it is given in the
         Symbol AFM file, but we decided, given the extremely
         litigious stance of a certain computer company with respect
         to its intellectual properties, NOT to make an apple screen
         character in the screen font file SYMBOL.SFT -- thus, a box,
         not an apple, appears on the drawing screen). You can see
         what your PostScript-compatible printer shows as the
         character associated with Alt 240 by sending the file
         ENCODING.PS, included on one of the distribution disks, to
         the printer.
           The Symbol and ZapfDingbat fonts have their own special
         screen fonts, since their encodings are special. Drawing
         files showing the standard, Symbol, and ZapfDingbat screen
         fonts (at 50-point size) are on one of the PictureThis
         distribution disks, as listed below.

         FILE NAME              FONT(S)
         STANDARD.DRW           standard-encoding
         SYMBOL.DRW             Symbol
         ZAPFDBLO.DRW           ZapfDingbats (typewriter keys:
                                  [space] through ~)
         ZAPFDBHI.DRW           ZapfDingbats (high-order keys: Alt 161
                                  through Alt 254)

           If, when setting text, you see the error message "NOT
         ENOUGH MEMORY TO DRAW TEXT" and/or "OUT OF MEMORY: PRESS J
         OR SAVE DRAWING," press any key and then press D (redraw
         screen) or J (jabber). Redrawing frees up some memory. One
         alternative when memory is low is to "greek" the text, using
         the J key. "Greeked" text requires significantly less memory
         than does text shown with screen font characters. (You can
         still use the "jabber" setting that shows the characters on
         the Quickshow screen, since these use no memory.) Other
         alternatives are to turn off the Background-save for text
         (see Section 31.) or save and get (export then import) the
         drawing.

         18.8. CUTTING TEXT BLOCKS FOR RE-EDITING

           Now that you can put text on the drawing screen, what if
         you want to edit it again? The text menu (accessed via F8)
         allows (prompted) deletion of entire text blocks, but if you
         have less drastic editing in mind, press C (for "cut") at
         the edit menu. The cursor STAYS WHERE IT IS, the text (or
         greeking lines) of a nearby block become dashed (if on the
         screen), and an information box containing the text
         parameters of the dashed text block appears at the bottom of
         the screen. To edit the dashed block, press Enter; the text
         is "cut" from the drawing, and placed back in the editor. If
         you want to edit a different text block, press + (same as
         Space) and/or - to cycle through all of the text blocks on
         the drawing, then choose one with Enter. The chosen text is
         returned to the editor, as you can see by pressing E or
         Enter or F8.
           If there already was text in the editor, then the cut text

                                        72

         goes AHEAD OF it, and a "quit set text" marker is placed
         between the cut text and the original text (this allows you
         to quickly remove, edit, and replace text without affecting
         existing text in the editor). WARNING: IF THE CUTTING
         OPERATION BRINGS IN MORE TEXT THAN THE EDITOR CAN HOLD, THE
         END OF THE EXISTING TEXT IS LOST IRRETRIEVABLY! Note: An
         easy way to move existing text blocks around is to place the
         cursor where you want a text block to start, cut the text
         block from its old position, enter the editor, and press F5
         to set the text block at the new position. A text block that
         is moved in this way draws on the screen faster than one
         that is moved by the object moving operation.
           During the cutting operation, if the cut text block has a
         different margin than the current margin, you are asked
         whether you want to change the current margin to that of the
         cut block; if the cut text block has different text
         parameters than the current ones, you are asked whether you
         want to change the current parameters to those of the cut
         block.

         18.9. TRANSFORMING TEXT BLOCKS

           In PictureThis, text blocks can be treated as objects:
         they can be subjected to any of the operations accessed via
         the object menu, including grouping with other objects (text
         blocks and/or trails), ungrouping, erasing, layering,
         moving, copying, scaling, rotating, flipping, and inclining.
         Use the object menu (via F7, see Sections 16 and 17) to
         perform any of these operations on any text block which has
         its beginning on the current drawing screen. Also note that
         text blocks can be saved (as objects) as clip art, for
         importing into other drawings.
           After a text block has been moved, copied, scaled,
         rotated, flipped, and/or inclined (several operations can be
         performed in succession), it has a new margin appropriate to
         the transformation(s) applied to it -- in other words, you
         can end up with non-rectangular margins! The old margin is
         DELETED, unless it happens to be the default margin or the
         current margin.
           Because the scaling, rotating, flipping, and inclination
         operations generally result in altered text size, shape,
         and/or orientation, not just altered position, when text
         transformed by any of these operations is cut back to the
         editor, "T" (for transformed) appears at the lower left of
         the editing screen to remind you that the editor's counting
         applies to the text as it was PRIOR to being transformed.
         Yes, you can still edit an upside-down, rescaled, inclined,
         and even flipped (so the letters are backwards!) text block
         -- but what you see in the editor will most definitely NOT
         be what you get on the drawing! The editor's "counting" WILL
         be PROPORTIONAL to the transformed result's dimensions,
         since all of the transformations are linear. Enough said.
         You can "play around" with transformations to discover
         exactly what all of this REALLY means, if you want. We do
         recommend that you spend at least a few minutes trying out
         text block transformations prior to trying them in a "real"
         drawing. That way, (most of) the surprises you find (when
         what you thought would happen DOESN'T!!) will be more
         instructive than catastrophic.
           Finally, note that DRAWINGS WITH TEXT CANNOT BE SCALED VIA

                                        73

         THE MISCELLANEOUS MENU. If you try, you'll get an error
         message. Sorry, but we don't think users would enjoy working
         in fractional text point sizes! It is sometimes important to
         scale a drawing to the desired dimensions BEFORE adding any
         text (see Section 22.2). DRAWINGS WITH TEXT STILL CAN BE
         SCALED WHEN AN ENCAPSULATED POSTSCRIPT FILE IS WRITTEN.

         18.10. MODIFICATION OF FONTS

           The MODFONT.EXE utility program (included on one of the
         distribution disks) allows you to begin with a particular
         set of "old" font information files (previously made with
         AFMTOPT.EXE (see Section 18.1), and having an identification
         number between 1 and 9999), and make a new set of font
         information files with various modifications (also having an
         identification number between 1 and 9999, which can be the
         same as that of the files to be modified, in which case the
         new files WRITE OVER the old files WITHOUT WARNING). The new
         font information files are written to the directory
         containing the old font files.
           Using MODFONT.EXE is self-explanatory. You can use the
         program to create modified fonts with any combination of the
         following:
           1. Characters slanted between -60 (counterclockwise) and
         +60 degrees (clockwise) from vertical, with the same height
         as the unmodified font characters. The slant angle is shown
         on-screen when "text" is toggled on (see Section 18.7); this
         slant angle does NOT add to the default 10 degree slant
         angle when an italic font is slanted.
           2. Outlined characters with the (black) outline thickness
         adjustable between 0 and 100 units. Note: Because of the way
         the PostScript language specifies outlined characters, a
         "limitcheck" error can occur if you attempt to print several
         outlined characters in sequence; a workaround is to make
         sure that there is a typesetting code (even one that
         effectively does nothing) after every few words having
         outlined characters. Also because of PostScript
         idiosyncracies, you cannot use non-zero track kerning (see
         Section 18.6) with outlined characters -- you'll see an
         error message if you attempt this. One use of outlined
         characters is to make bolder than normal characters (with
         text gray = 100%); too bad track kerning can't be used with
         these characters to space them a bit further apart! If you
         want to see an outlined character with a different color
         interior than exterior, set the text gray to the desired
         interior color (e.g., for white interior, text gray should
         be 0%). The outline is always black.
           3. Width of characters = 0.1 to 10 times base width
           4. Altered default settings for superscript character
         point size (1 to 100% of normal point size -- if you don't
         alter this, it is 70%) and for superscript character
         baseline position (0 to 100% of normal point size above the
         normal baseline -- if you don't alter this, it is 50%).
           5. Altered default settings for subscript character point
         size (1 to 100% of normal point size -- if you don't alter
         this, it is 70%) and for subscript character baseline
         position (0 to 100% of normal point size below the normal
         baseline -- if you don't alter this, it is 20%).
           6. Altered default settings for positioning of parts of
         accented (composite) characters.

         19. FILE OPERATIONS AND DOS SHELL

           All file input/output operations and the "shell" to the
         operating system are accessed by pressing F10. The state
         changes to "FILES," and a menu appears at the top of the
         screen, with eight options: GetDRW, SaveDRW, ImportCLP,
         ExportCLP, ReadTMP, WriteEPS, DOS, and UseDAT.

         19.1. GETTING A SAVED DRAWING

           At the file menu, the GetDRW option (for retrieving a
         PictureThis-format drawing file previously saved with the
         SaveDRW option (see Section 19.2)) is accessed by pressing
         G. A prompt appears at the top of the screen. The first line
         of this prompt states: "Enter filespec for DRW retrieval."
         The second line is a file specification using your current
         directory as the path, "*" for the filename and "DRW" for
         the file extension. (We strongly recommend using the file
         extension "DRW" for your drawing files.) If you press Enter,
         you see a directory list of all files matching the
         specification in the second line of the prompt. Press the
         cursor keys to highlight the drawing file which you want to
         retreive. Press Enter and that file is retrieved.
           If you want to view the directory for a different file
         specification, instead of pressing Enter at the file
         specification prompt, key in the desired file specification
         (with a "*" or "?" to indicate a "wild card").
           If you want to retrieve a specific file without viewing
         the directory, key in the filename (with extension and the
         appropriate path specification if necessary) of a drawing
         file saved previously with the SaveDRW option, then press
         Enter. PictureThis saves the path you enter and uses it as
         the path for your next drawing retrieval.
           Within a short time, the saved drawing should appear. If
         not, pay heed to any error messages and try again. Note:
         Drawings saved using PictureThis 1, 2, or 3 are retrieved
         correctly. Your current drawing is cleared when you bring in
         a new drawing; SAVE THE OLD DRAWING FIRST IF YOU DON'T WANT
         TO LOSE IT.

         19.2. SAVING A DRAWING

           At the file menu, the SaveDRW option (for saving the
         current drawing to disk for subsequent use in PictureThis)
         is accessed by pressing S. If you have previously retrieved
         or saved a drawing, a prompt appears asking if you want to
         use the most recent file specification. If you answer Y, the
         current drawing is saved with the file specification shown.
         If you answer N, or if you have not previously retrieved or
         saved a drawing, a different prompt appears at the top of
         the screen. The first line of this prompt states: "Enter
         filespec for DRW save." The second line is a file
         specification using your current directory as the path, "*"
         for the filename, and "DRW" for the file extension. (We
         strongly recommend using the extension "DRW" for your
         drawing files.) If you press Enter, the screen changes to a
         directory list of all files matching the specification in
         the second line of the prompt. Press the cursor keys to
         highlight the drawing file specification which you want to
         save the current drawing as and press Enter. The current

                                        75

         drawing is saved with the selected specification.
           If you want to view the directory for a different file
         specification, instead of pressing Enter at the file
         specification prompt, key in the desired file specification
         (with a "*" or "?" to indicate a "wild card").
           If you want to save your drawing file with a particular
         specification without viewing the directory, at the file
         specification prompt, key in the desired specification (with
         extension and the appropriate path if necessary), then press
         Enter. PictureThis saves the path you enter and uses it as
         the path for the next drawing retrieval or save. If a file
         with the specification which you keyed in already exists, a
         prompt appears, asking if you want to write over the
         existing file. If you do, press Y; if not, press N and you
         will be able to enter a different file specification.
           The saved drawing includes all of the curves and text
         blocks on the current drawing, not just those curves and
         text blocks visible on the current screen. It also includes
         the trail, object, and drawing sequence information. Along
         with the actual drawing, the current frame (see Section
         22.1), the current units (see Section 20.1), the current
         grid (see Section 21.2), the positions of all noted points
         (see Section 23.1), the scale of the drawing (see Section
         22.2), the slow and fast cursor speeds (see Section 21.1),
         the dash patterns (see Section 15.2), the margins (see
         Section 18.4), the text parameter sets (see Section 18.3),
         text block information (see Section 18.4), and the
         background save setting (see Section 31.) are all saved. The
         file saved DOES NOT include template information. Try to
         save the file again if you get an error message (after
         attempting to correct the problem). Note: Saving a drawing
         deletes from the drawing file all erased curves, endpoints,
         trails, text blocks, and objects (which have been erased
         directly or by various other operations). This can be useful
         when memory limits are being approached (see Section 31.).
         To free up some memory, save the drawing and bring it back
         in. WE RECOMMEND FREQUENT SAVING WHILE DRAWING, FOR
         SAFETY!!!

         19.3. IMPORTING CLIP ART

           At the file menu, the ImportCLP option for importing into
         the current drawing a PictureThis-format clip art file
         previously saved with the ExportCLP option (see Section
         19.4) is accessed by pressing I. A prompt appears at the top
         of the screen. The first line of the prompt states: "Enter
         filespec for CLP retrieval". The second line is a file
         specification using your current directory as the path, "*"
         for the filename, and "CLP" for the file extension. (We
         strongly recommend using CLP as the file extension for your
         clip art files.) If you press Enter, you see a directory
         list of all files matching the specification in the second
         line of the prompt. Press the cursor keys to highlight the
         clip art file which you wish to import and press Enter. That
         file is retrieved.
           If you want to view the directory for a different file
         specification, instead of pressing Enter at the file
         specification prompt, key in the desired file specification
         (with a "*" or "?" to indicate a "wild card").
           If you want to retrieve a specific file without viewing the

                                        76

         directory, key in the filename (with extension and the
         appropriate path specification if necessary) of a clip art
         file saved previously with the ExportCLP option, then press
         Enter. PictureThis saves the path you enter and uses it as
         the path for the next clip art retrieval.
           When a clip art file is retrieved, the previously saved
         clip art object is added to your current drawing (without
         endpoints) and the prompt "OK? (Y/N)" appears. If you are
         satisfied with the imported object, press Y; the object is
         drawn with endpoints, and the state returns to "FREE." (Note
         that the imported object is placed wherever it was on the
         screen when it was exported. It can be moved easily (see
         Section 17.1).) If you are not satisfied with the imported
         object, press N in response to the prompt, and you can key
         in a different file specification.
           Notice that your current drawing is NOT cleared when you
         import a clip art object. The imported clip art object is
         placed at the front of the current drawing, but it can be
         relayered (see Section 16.4).
           If you import a clip art object which contains text and
         was saved when the scaling was different than the current
         scaling (see Section 22), the text might be of slightly
         different size than the original. This is because the text
         must be scaled, and the point size of the text cannot be
         fractional. This is quite noticeable with long text blocks
         and small point sizes, so try to avoid it in this case.

         19.4. EXPORTING CLIP ART

           While at the file menu, the ExportCLP option (for saving a
         clip art object to disk for subsequent importing into a
         PictureThis drawing) is accessed by pressing E. The cursor
         jumps to the closest initial point of an outermost object,
         trail, or text block, and that object is dashed. An
         instruction box appears ("Next: +, Space"/"Previous: -"/
         "Select: Enter").
           Press +, Space, and/or - repeatedly until the object which
         you want to save is dashed. Then press Enter. Pressing Esc
         returns the files menu. If only one object is available, it
         is chosen automatically.
           If you have previously retrieved or saved a clip art
         object, a prompt appears asking if you want to use the most
         recent file specification. If you answer Y, the selected
         object is saved with that file specification. If you answer
         N or you have not previously retrieved or saved a clip art
         object, a different prompt appears at the top of the screen.
         The first line of this prompt states: "Enter filespec for
         CLP save." The second line is a file specification using
         your current directory as the path, "*" for the filename,
         and "CLP" for the file extension. (We strongly recommend
         using the extension "CLP" for your clip art files.) If you
         press Enter, you see a directory list of all files matching
         the specification in the second line of the prompt. Press
         the cursor keys to highlight the desired clip art file
         specification and press Enter. The selected object is saved
         with the selected specification.
           If you want to view the directory for a different file
         specification, instead of pressing Enter at the file
         specification prompt, key in the desired file specification
         (with a "*" or "?" to indicate a "wild card").

                                        77

           If you want to save the selected object as with a
         particular file specification without viewing the directory,
         key in the filename (with extension and the appropriate path
         specification if necessary), then press Enter. PictureThis
         saves the path you enter and uses it as the path for the
         next clip art retrieval or save. If the file with the
         specification which you keyed in already exists, a prompt
         appears asking if you want to write over the existing file.
         If you do, press Y; if not, press N and you will be able to
         enter a different file specification.

         19.5. READING A TEMPLATE FILE

           At the file menu, the ReadTMP option (for retrieving a
         template previously captured with the CaptureThis or
         Alternate CaptureThis programs, as discussed in Section
         26.1) is accessed by pressing R. A prompt appears at the top
         of the screen. The first line of this prompt states: "Enter
         filespec for TMP retrieval." The second line is a file
         specification using your current directory as the path, "*"
         for the filename and "TMP" for the file extension. (We
         strongly recommend using the file extension "TMP" for your
         template files.) If you press Enter, you see a directory
         list of all files matching the specification in the second
         line of the prompt. Press the cursor keys to highlight the
         template file which you want to retreive and press Enter.
         That file is retrieved.
           If you want to view the directory for a different file
         specification, instead of pressing Enter at the file
         specification prompt, key in the desired file specification
         (with a "*" or "?" to indicate a "wild card").
           If you want to retrieve a specific file without viewing
         the directory, key in the filename (with extension and the
         appropriate path specification if necessary) of a template
         file saved previously with CaptureThis or Alternate
         CaptureThis program, then press Enter. PictureThis saves the
         path you enter and uses it as the path for the next template
         retrieval.
           The template is placed at the center of the 50% screen
         unless a previous template was moved. Templates can be moved
         around the screen easily (see Section 26.2).
           Note that templates saved from a CGA screen can ONLY be
         used when you are in CGA screen mode. Templates saved from
         EGA and VGA screens CANNOT be used in CGA screen mode. EGA
         and VGA templates can be used interchangeably, however if
         you use an EGA template in VGA mode or a VGA template in EGA
         mode, the template's aspect ratio will be wrong and it will
         either look streched or squashed. Also the bottom will lost
         off a VGA template in EGA mode.
           Importing a template in VGA screen mode ONLY requires some
         memory. If that memory is not available, you will only be
         able to see the top portion of the template. Even if you
         turn off the template by pressing "T" (see Section 25.3),
         this memory is not freed. If you no longer need the
         template, and you need extra memory, save your drawing, exit
         PictureThis, restart PictureThis, and import your drawing.

         19.6. WRITING A POSTSCRIPT FILE

           At the file menu, the WriteEPS option (for saving an

                                        78

         encapsulated PostScript file to disk for subsequent delivery
         to a laser printer, imagesetter, or page layout program) is
         accessed by pressing W. PictureThis allows a great deal of
         flexibility in specifying how PostScript output appears. One
         or multiple ("tiled") pages are allowed. The printed drawing
         can be small or large, and it can be scaled irregularly.
         Also, the drawing can be placed anywhere on the page, in
         "portrait" or "landscape" orientation (see below). To
         specify these parameters, several prompts appear in
         succession. These prompts all have current values which are
         acceptable in many cases. If the current value is acceptable
         for a prompt, just press Enter. Changes to any parameter are
         made by typing a new value in. Esc backs out to the previous
         prompt (with its current value), so you can reset a
         parameter without starting from the beginning.
           When you press W at the file menu, a query appears: "Use
         current settings? (Y/N)." If you press Y, ALL current
         settings (see below for descriptions of each type of
         setting) are used for saving an EPS file, and a prompt for a
         file specification appears. The default current
         specification is *.EPS in the current directory. We strongly
         recommend that you use the extension "EPS" for PostScript
         files created using PictureThis -- some desktop publishing
         programs REQUIRE this extension to read an EPS file. If you
         previously saved an EPS file, the current specification is
         that of the last-saved EPS file. Either press Enter to see a
         list of files matching the current specification and then
         move the block cursor to the desired filename and press
         Enter to use it for saving, or key in a new specification
         and press Enter to use it for saving. Pressing any key
         (INCLUDING Esc) other than Y at the use current settings
         query shows the first in a series of prompts which allow
         changes to each setting, as described below.
           The first four prompts request information about the size
         and margins of the physical page on which you are printing.
         Initially, the size is set to 8.5 inches by 11 inches, and
         the margins are set to .25 inches all around. It is
         important to note that changing these parameters does NOT
         alter your output device (printer or imagesetter) to accept
         a different size paper or have different margins; those
         adjustments must be done independently, and the procedures
         vary with output device (see your output devive owner manual
         for more information). PictureThis uses the parameters to
         position drawings on individual pages, and to determine the
         printing area for multiple page drawings. The initial
         settings are acceptable in many cases, even if the margins
         of the printer you are using are slightly different. If you
         change any of these four parameters, the new values remain
         for the rest of your PictureThis session, unless they are
         changed by accessing the prompts again.
           Next a menu appears showing the current orientation
         (Portrait (the default) or Landscape). Press Enter to accept
         the current orientation or P or L to change it. "Landscape
         orientation" means that the printed output has the drawing's
         WIDTH (WHETHER OR NOT IT IS LONGER THAN THE DRAWING'S
         HEIGHT) oriented PARALLEL to the paper's height. The WIDTH
         direction always corresponds to the HORIZONTAL direction on
         your monitor screen, and the HEIGHT direction always
         corresponds to the VERTICAL direction on your monitor
         screen. "Portrait orientation" means that the drawing's

                                        79

         WIDTH is oriented PARALLEL to the paper's width. See the
         diagrams below.

         NOTE: THE DEFAULT DRAWING WIDTH IS LONGER THAN DRAWING
         HEIGHT.
           The next prompt requests the drawing width in inches. The
         first line of this prompt shows the current drawing width.
         Initially, it is set from your drawing's frame (see Section
         22.1) and scale (see Section 22.2). (Remember that parts of
         your drawing outside of the frame do NOT print.) If you have
         not changed the frame or the drawing's scale, the width is
         8.00 inches. If you want to change the drawing's width, key
         in a new value greater than 0 inches and less than 7500
         inches. Obviously, you seldom will want to scale the drawing
         near either of the two extremes! If you do change the width
         of the drawing, another prompt appears: "Scale line weights
         with width? (Y/N)";  otherwise, a box with instructions for
         changing the height appears (described in the next
         paragraph). Scaling line weights means that the thicknesses
         of curves on the printed output are scaled proportionally to
         the width; they have the values assigned when they were
         originally drawn if the width setting is not changed. To
         scale line weights with width, press Y. To use the line
         weight values originally assigned when the curves were
         drawn, regardless of width setting changes, press any other
         key.
           Next, another prompt appears, requesting you to set the
         height of the drawing. The first line of the prompt ("Height
         if scaled uniformly: XXX.XX"), shows the height of the
         drawing if it is scaled uniformly with the current width.
         (This depends on the drawing's frame (see Section 22.1) and
         the aspect ratio (see Section 24).) If you want to change
         the height setting for the printed drawing output (thus
         altering the proportional scaling of width to height), key
         in a new height. (Note: if you come back to this prompt via
         one or more presses of Esc or if you accept the current
         width in the previous step, the first line changes to
         "Current height of drawing:" followed by the height which
         you entered or accepted previously.) (Note that the drawing
         width and height are not saved as such, rather, a scale
         factor is saved for each, relating the default width/height

                                        80

         to the entered width/height. Thus, if you change the frame
         or rescale the drawing between EPS saves, the new
         width/height is its scale factor times the width/height of
         the frame. If you don't change the frame or scaling, the
         width/height doesn't change.)
           The next two prompts allow you to specify where the top
         left corner of the drawing's frame will appear on the paper.
         The first prompt requests the "horizontal indent": how far
         the left edge of the drawing's frame will be from the left
         edge of the paper. The initial value is the left margin of
         the paper (as set above). You can change this value to be
         anywhere between the left and right margins. The second
         prompt requests the "vertical indent": how far the top edge
         of the drawing's frame will be from the top edge of the
         paper. The initial value is the top margin of the paper (as
         set above). You can change this value to be anywhere between
         the top and bottom margins. (Note that if you indent too
         much, a drawing which normally would fit on one page extends
         to two or four pages.)
           From the settings, PictureThis calculates how many
         physical pages will be required for the drawing. If the
         result is more than one page, two more prompts appear. The
         first prompt asks if you want to overlap the page margins.
         If you answer Y, the separate page outputs have a .25 inch
         overlap -- the last 1/4 inch of the page also is the first
         1/4 inch on the next page, both horizontally and vertically.
         If you press any other key (except Esc), there is no
         overlap. Experiment to find which method is preferable for
         assembling multiple page drawings. After this prompt is
         answered, another prompt appears stating how many pages wide
         and high your output will be. It also warns you that the
         file to be saved is NOT an Encapsulated PostScript file.
         Only drawing outputs fitting on a single page are made into
         EPS files which can be incorporated into other programs.
         Drawings requiring multiple pages are simple, but not
         Encapsulated, PostScript programs which can be sent to
         PostScript-compatible printers. (Of course, you can make a
         single-page EPS file from any drawing, by proper scaling.)
         Now you are asked if you want to continue. If the number of
         pages is satisfactory, press Y. Otherwise, press any other
         key, and you will be taken back to the drawing width prompt,
         so you can respecify the parameters.
           Finally, a prompt for the specification for the file to be
         saved appears. If you have previously saved an EPS file in
         the current PictureThis session, you are asked if you want
         to use the last entered file specification. If you answer Y,
         that specification is used. If you answer N, or if you are
         saving an EPS file for the first time in this PictureThis
         session, you see a prompt asking you to enter a file
         specification. The second line of this prompt is a file
         specification with the current directory, "*" for the
         filename, and "EPS" for the extension. (We strongly
         recommend using the extension "EPS" for Encapsulated
         PostScript files created with PictureThis.) If you press
         Enter, a directory appears for the file specification on the
         second line. Use the cursor keys to move the block cursor,
         and press Enter when the filename which you wish to use is
         highlighted. If you press Esc, you back out to the previous
         prompt. To see the directory for a different "wild card"
         file specification, key in that specification at the file

                                        81

         specification prompt; an appropriate directory appears. The
         new specification becomes the current specification for the
         next EPS file save. Alternatively, at the file specification
         prompt you can key in the desired filename (with an
         extension and the appropriate operating system path
         specification if necessary) for saving. If this file already
         exists, you are asked if you want to write over it. An Esc
         from the file specification prompt backs out ALL THE WAY TO
         THE FILES MENU.
           After the file specification is selected in one of the
         above ways, two more prompts appear. "Created by?" is the
         first. Key in an appropriate response, then press Enter (or
         just press Enter). "Title?" is the next prompt that appears.
         Key in a title for your drawing, and press Enter (or just
         press Enter). These last two prompt answers have no effect
         on your printed drawing. They are put in the "comments"
         section at the beginning of the file you are saving (along
         with the date of file creation, as indicated by the
         operating system clock); they sometimes are used by page
         layout programs to aid in file identification.
           Wait until disk activity has stopped before you continue.
         (If you get an error message, attempt to correct the
         problem, then try again.)
           Encapsulated PostScript files (EPSFs) produced by
         PictureThis contain only ASCII characters, so they can be
         viewed with the operating system "TYPE" command, and they
         can be edited with most word processing programs; also, they
         can be merged with other PostScript files (see Section
         19.8), such as those produced by page layout programs (some
         of which have the ability to recognize EPSFs for positioning
         and scaling). PostScript files created by PictureThis can
         also be delivered directly to PostScript-compatible output
         devices to produce printed output.
           If you know how to program in PostScript, you can modify
         the output by appropriate editing of the PostScript files.
