ef2cbb24 | 46 | ;; -------------- |
bcc0d457 | 47 | ;; |
ef2cbb24 RS |
48 | ;; This package provides printing of Emacs buffers on PostScript |
49 | ;; printers; the buffer's bold and italic text attributes are | |
50 | ;; preserved in the printer output. Ps-print is intended for use with | |
00aa16af RS |
51 | ;; Emacs 19 or Lucid Emacs, together with a fontifying package such as |
52 | ;; font-lock or hilit. | |
12d89a2e | 53 | ;; |

12d89a2e | 55 | ;; Using ps-print |
ef2cbb24 | 56 | ;; -------------- |
ef2cbb24 | 57 | ;; |
12d89a2e RS |
58 | ;; The Commands |
59 | ;; | |
60 | ;; Ps-print provides eight commands for generating PostScript images | |
61 | ;; of Emacs buffers: | |
62 | ;; | |
63 | ;; ps-print-buffer | |
64 | ;; ps-print-buffer-with-faces | |
65 | ;; ps-print-region | |
66 | ;; ps-print-region-with-faces | |
67 | ;; ps-spool-buffer | |
68 | ;; ps-spool-buffer-with-faces | |
69 | ;; ps-spool-region | |
70 | ;; ps-spool-region-with-faces | |
71 | ;; | |
72 | ;; These commands all perform essentially the same function: they | |
73 | ;; generate PostScript images suitable for printing on a PostScript | |
74 | ;; printer or displaying with GhostScript. These commands are | |
75 | ;; collectively referred to as "ps-print- commands". | |
76 | ;; | |
77 | ;; The word "print" or "spool" in the command name determines when the | |
78 | ;; PostScript image is sent to the printer: | |
ef2cbb24 | 79 | ;; |
12d89a2e RS |
80 | ;; print - The PostScript image is immediately sent to the |
81 | ;; printer; | |
ef2cbb24 | 82 | ;; |
12d89a2e RS |
83 | ;; spool - The PostScript image is saved temporarily in an |
84 | ;; Emacs buffer. Many images may be spooled locally | |
85 | ;; before printing them. To send the spooled images | |
bcc0d457 | 86 | ;; to the printer, use the command `ps-despool'. |
ef2cbb24 | 87 | ;; |
12d89a2e RS |
88 | ;; The spooling mechanism was designed for printing lots of small |
89 | ;; files (mail messages or netnews articles) to save paper that would | |
90 | ;; otherwise be wasted on banner pages, and to make it easier to find | |
91 | ;; your output at the printer (it's easier to pick up one 50-page | |
92 | ;; printout than to find 50 single-page printouts). | |
93 | ;; | |
bcc0d457 | 94 | ;; Ps-print has a hook in the `kill-emacs-hooks' so that you won't |
a7acbbe4 | 95 | ;; accidentally quit from Emacs while you have unprinted PostScript |
12d89a2e RS |
96 | ;; waiting in the spool buffer. If you do attempt to exit with |
97 | ;; spooled PostScript, you'll be asked if you want to print it, and if | |
98 | ;; you decline, you'll be asked to confirm the exit; this is modeled | |
99 | ;; on the confirmation that Emacs uses for modified buffers. | |
100 | ;; | |
101 | ;; The word "buffer" or "region" in the command name determines how | |
102 | ;; much of the buffer is printed: | |
103 | ;; | |
104 | ;; buffer - Print the entire buffer. | |
105 | ;; | |
106 | ;; region - Print just the current region. | |
107 | ;; | |
108 | ;; The -with-faces suffix on the command name means that the command | |
109 | ;; will include font, color, and underline information in the | |
110 | ;; PostScript image, so the printed image can look as pretty as the | |
111 | ;; buffer. The ps-print- commands without the -with-faces suffix | |
112 | ;; don't include font, color, or underline information; images printed | |
113 | ;; with these commands aren't as pretty, but are faster to generate. | |
114 | ;; | |
115 | ;; Two ps-print- command examples: | |
116 | ;; | |
117 | ;; ps-print-buffer - print the entire buffer, | |
118 | ;; without font, color, or | |
119 | ;; underline information, and | |
120 | ;; send it immediately to the | |
121 | ;; printer. | |
122 | ;; | |
123 | ;; ps-spool-region-with-faces - print just the current region; | |
124 | ;; include font, color, and | |
125 | ;; underline information, and | |
126 | ;; spool the image in Emacs to | |
127 | ;; send to the printer later. | |
128 | ;; | |
129 | ;; | |
130 | ;; Invoking Ps-Print | |
bcc0d457 | 131 | ;; ----------------- |
ef2cbb24 | 132 | ;; |
12d89a2e | 133 | ;; To print your buffer, type |
ef2cbb24 | 134 | ;; |
12d89a2e | 135 | ;; M-x ps-print-buffer |
ef2cbb24 | 136 | ;; |
12d89a2e RS |
137 | ;; or substitute one of the other seven ps-print- commands. The |
138 | ;; command will generate the PostScript image and print or spool it as | |
139 | ;; specified. By giving the command a prefix argument | |
140 | ;; | |
141 | ;; C-u M-x ps-print-buffer | |
142 | ;; | |
143 | ;; it will save the PostScript image to a file instead of sending it | |
144 | ;; to the printer; you will be prompted for the name of the file to | |
145 | ;; save the image to. The prefix argument is ignored by the commands | |
146 | ;; that spool their images, but you may save the spooled images to a | |
bcc0d457 | 147 | ;; file by giving a prefix argument to `ps-despool': |
12d89a2e RS |
148 | ;; |
149 | ;; C-u M-x ps-despool | |
150 | ;; | |
bcc0d457 | 151 | ;; When invoked this way, `ps-despool' will prompt you for the name of |
12d89a2e RS |
152 | ;; the file to save to. |
153 | ;; | |
bcc0d457 RS |
154 | ;; Any of the `ps-print-' commands can be bound to keys; I recommend |
155 | ;; binding `ps-spool-buffer-with-faces', `ps-spool-region-with-faces', | |
156 | ;; and `ps-despool'. Here are the bindings I use on my Sun 4 keyboard: | |
12d89a2e RS |
157 | ;; |
158 | ;; (global-set-key 'f22 'ps-spool-buffer-with-faces) ;f22 is prsc | |
ef2cbb24 RS |
159 | ;; (global-set-key '(shift f22) 'ps-spool-region-with-faces) |
160 | ;; (global-set-key '(control f22) 'ps-despool) | |
161 | ;; | |
12d89a2e RS |

163 | ;; The Printer Interface | |
bcc0d457 | 164 | ;; --------------------- |
12d89a2e | 165 | ;; |
bcc0d457 | 166 | ;; The variables `ps-lpr-command' and `ps-lpr-switches' determine what |
12d89a2e | 167 | ;; command is used to send the PostScript images to the printer, and |
bcc0d457 RS |
168 | ;; what arguments to give the command. These are analogous to |
169 | ;; `lpr-command' and `lpr-switches'. | |
170 | ;; Make sure that they contain appropriate values for your system; | |
171 | ;; see the usage notes below and the documentation of these variables. | |
172 | ;; | |
173 | ;; NOTE: `ps-lpr-command' and `ps-lpr-switches' take their initial values | |
174 | ;; from the variables `lpr-command' and `lpr-switches'. If you have | |
175 | ;; `lpr-command' set to invoke a pretty-printer such as `enscript', | |
176 | ;; then ps-print won't work properly. `ps-lpr-command' must name | |
12d89a2e RS |
177 | ;; a program that does not format the files it prints. |
178 | ;; | |
179 | ;; | |
bcc0d457 RS |
180 | ;; The Page Layout |
181 | ;; --------------- | |
12d89a2e | 182 | ;; |
bcc0d457 RS |
183 | ;; All dimensions are floats in PostScript points. |
184 | ;; 1 inch == 2.54 cm == 72 points | |
185 | ;; 1 cm == (/ 1 2.54) inch == (/ 72 2.54) points | |
12d89a2e | 186 | ;; |
bcc0d457 RS |
187 | ;; The variable `ps-paper-type' determines the size of paper ps-print |
188 | ;; formats for; it should contain one of the symbols: | |
189 | ;; `a4' `a3' `letter' `legal' `letter-small' `tabloid' | |
190 | ;; `ledger' `statement' `executive' `a4small' `b4' `b5' | |
12d89a2e | 191 | ;; |
bcc0d457 RS |
192 | ;; The variable `ps-landscape-mode' determines the orientation |
193 | ;; of the printing on the page: | |
194 | ;; nil means `portrait' mode, non-nil means `landscape' mode. | |
195 | ;; There is no oblique mode yet, though this is easy to do in ps. | |
196 | ||
197 | ;; In landscape mode, the text is NOT scaled: you may print 70 lines | |
198 | ;; in portrait mode and only 50 lignes in landscape mode. | |
199 | ;; The margins represent margins in the printed paper: | |
200 | ;; the top margin is the margin between the top of the page | |
201 | ;; and the printed header, whatever the orientation is. | |
043620f4 | 202 | ;; |
bcc0d457 RS |
203 | ;; The variable `ps-number-of-columns' determines the number of columns |
204 | ;; both in landscape and portrait mode. | |
205 | ;; You can use: | |
206 | ;; - (the standard) one column portrait mode | |
207 | ;; - (my favorite) two columns landscape mode (which spares trees) | |
208 | ;; but also | |
209 | ;; - one column landscape mode for files with very long lines. | |
210 | ;; - multi-column portrait or landscape mode | |

213 | ;; Horizontal layout |
214 | ;; ----------------- | |
12d89a2e | 215 | ;; |
bcc0d457 RS |
216 | ;; The horizontal layout is determined by the variables |
217 | ;; `ps-left-margin' `ps-inter-column' `ps-right-margin' | |
218 | ;; as follows: | |
12d89a2e | 219 | ;; |
bcc0d457 RS |
220 | ;; ------------------------------------------ |
221 | ;; | | | | | | | | | |
222 | ;; | lm | text | ic | text | ic | text | rm | | |
223 | ;; | | | | | | | | | |
224 | ;; ------------------------------------------ | |
12d89a2e | 225 | ;; |
bcc0d457 RS |
226 | ;; If `ps-number-of-columns' is 1, `ps-inter-column' is not relevant. |
227 | ;; Usually, lm = rm > 0 and ic = lm | |
228 | ;; If (ic < 0), the text of adjacent columns can overlap. | |
12d89a2e | 229 | ;; |
12d89a2e | 230 | ;; |
bcc0d457 RS |
231 | ;; Vertical layout |
232 | ;; --------------- | |
233 | ;; | |
234 | ;; The vertical layout is determined by the variables | |
235 | ;; `ps-bottom-margin' `ps-top-margin' `ps-header-offset' | |
236 | ;; as follows: | |
237 | ;; | |
238 | ;; |--------| |--------| | |
239 | ;; | tm | | tm | | |
240 | ;; |--------| |--------| | |
241 | ;; | header | | | | |
242 | ;; |--------| | | | |
243 | ;; | ho | | | | |
244 | ;; |--------| or | text | | |
245 | ;; | | | | | |
246 | ;; | text | | | | |
247 | ;; | | | | | |
248 | ;; |--------| |--------| | |
249 | ;; | bm | | bm | | |
250 | ;; |--------| |--------| | |
251 | ;; | |
252 | ;; If `ps-print-header' is nil, `ps-header-offset' is not relevant. | |
253 | ;; The margins represent margins in the printed paper: | |
254 | ;; the top margin is the margin between the top of the page | |
255 | ;; and the printed header, whatever the orientation is. | |
12d89a2e RS |
256 | ;; |
257 | ;; | |
258 | ;; Headers | |
bcc0d457 | 259 | ;; ------- |
12d89a2e | 260 | ;; |
bcc0d457 | 261 | ;; Ps-print can print headers at the top of each column; the default |
12d89a2e RS |
262 | ;; headers contain the following four items: on the left, the name of |
263 | ;; the buffer and, if the buffer is visiting a file, the file's | |
bcc0d457 RS |
264 | ;; directory; on the right, the page number and date of printing. |
265 | ;; The default headers look something like this: | |
12d89a2e RS |
266 | ;; |
267 | ;; ps-print.el 1/21 | |
268 | ;; /home/jct/emacs-lisp/ps/new 94/12/31 | |
269 | ;; | |
270 | ;; When printing on duplex printers, left and right are reversed so | |
bcc0d457 | 271 | ;; that the page numbers are toward the outside (cf. `ps-spool-duplex'). |
12d89a2e | 272 | ;; |
bcc0d457 RS |
273 | ;; Headers are configurable: |
274 | ;; To turn them off completely, set `ps-print-header' to nil. | |
275 | ;; To turn off the header's gaudy framing box, | |
276 | ;; set `ps-print-header-frame' to nil. | |
277 | ;; | |
278 | ;; The font family and size of text in the header are determined | |
279 | ;; by the variables `ps-header-font-family', `ps-header-font-size' and | |
280 | ;; `ps-header-title-font-size' (see below). | |
281 | ;; | |
282 | ;; The variable `ps-header-line-pad' determines the portion of a header | |
283 | ;; title line height to insert between the header frame and the text | |
284 | ;; it contains, both in the vertical and horizontal directions: | |
285 | ;; .5 means half a line. | |
286 | ||
287 | ;; Page numbers are printed in `n/m' format, indicating page n of m pages; | |
288 | ;; to omit the total page count and just print the page number, | |
289 | ;; set `ps-show-n-of-n' to nil. | |
12d89a2e RS |
290 | ;; |
291 | ;; The amount of information in the header can be changed by changing | |
bcc0d457 | 292 | ;; the number of lines. To show less, set `ps-header-lines' to 1, and |
12d89a2e | 293 | ;; the header will show only the buffer name and page number. To show |
bcc0d457 | 294 | ;; more, set `ps-header-lines' to 3, and the header will show the time of |
12d89a2e RS |
295 | ;; printing below the date. |
296 | ;; | |
297 | ;; To change the content of the headers, change the variables | |
bcc0d457 RS |
298 | ;; `ps-left-header' and `ps-right-header'. |
299 | ;; These variables are lists, specifying top-to-bottom the text | |
300 | ;; to display on the left or right side of the header. | |
301 | ;; Each element of the list should be a string or a symbol. | |
302 | ;; Strings are inserted directly into the PostScript arrays, | |
303 | ;; and should contain the PostScript string delimiters '(' and ')'. | |
12d89a2e RS |
304 | ;; |
305 | ;; Symbols in the header format lists can either represent functions | |
306 | ;; or variables. Functions are called, and should return a string to | |
307 | ;; show in the header. Variables should contain strings to display in | |
308 | ;; the header. In either case, function or variable, the PostScript | |
a7acbbe4 | 309 | ;; string delimiters are added by ps-print, and should not be part of |
12d89a2e RS |
310 | ;; the returned value. |
311 | ;; | |
312 | ;; Here's an example: say we want the left header to display the text | |
313 | ;; | |
314 | ;; Moe | |
315 | ;; Larry | |
316 | ;; Curly | |
317 | ;; | |
318 | ;; where we have a function to return "Moe" | |
319 | ;; | |
320 | ;; (defun moe-func () | |
321 | ;; "Moe") | |
322 | ;; | |
323 | ;; a variable specifying "Larry" | |
324 | ;; | |
325 | ;; (setq larry-var "Larry") | |
326 | ;; | |
bcc0d457 | 327 | ;; and a literal for "Curly". Here's how `ps-left-header' should be |
12d89a2e RS |
328 | ;; set: |
329 | ;; | |
330 | ;; (setq ps-left-header (list 'moe-func 'larry-var "(Curly)")) | |
331 | ;; | |
332 | ;; Note that Curly has the PostScript string delimiters inside his | |
bcc0d457 RS |
333 | ;; quotes -- those aren't misplaced lisp delimiters! |
334 | ;; Without them, PostScript would attempt to call the undefined | |
335 | ;; function Curly, which would result in a PostScript error. | |
336 | ;; Since most printers don't report PostScript errors except by | |
337 | ;; aborting the print job, this kind of error can be hard to track down. | |
338 | ;; Consider yourself warned! | |
12d89a2e RS |
339 | ;; |
340 | ;; | |
341 | ;; Duplex Printers | |
bcc0d457 | 342 | ;; --------------- |
12d89a2e RS |
343 | ;; |
344 | ;; If you have a duplex-capable printer (one that prints both sides of | |
bcc0d457 RS |
345 | ;; the paper), set `ps-spool-duplex' to t. |
346 | ;; Ps-print will insert blank pages to make sure each buffer starts | |
347 | ;; on the correct side of the paper. | |
348 | ;; Don't forget to set `ps-lpr-switches' to select duplex printing | |
349 | ;; for your printer. | |
350 | ;; | |
351 | ;; | |
352 | ;; Font managing | |
353 | ;; ------------- | |
354 | ;; | |
355 | ;; Ps-print now knows rather precisely some fonts: | |
356 | ;; the variable `ps-font-info-database' contains information | |
357 | ;; for a list of font families (currently mainly `Courier' `Helvetica' | |
358 | ;; `Times' `Palatino' `Helvetica-Narrow' `NewCenturySchlbk'). | |
359 | ;; Each font family contains the font names for standard, bold, italic | |
360 | ;; and bold-italic characters, a reference size (usually 10) and the | |
361 | ;; corresponding line height, width of a space and average character width. | |
ef2cbb24 | 362 | ;; |
bcc0d457 RS |
363 | ;; The variable `ps-font-family' determines which font family |
364 | ;; is to be used for ordinary text. | |
365 | ;; If its value does not correspond to a known font family, | |
366 | ;; an error message is printed into the `*Messages*' buffer, | |
367 | ;; which lists the currently available font families. | |
368 | ;; | |
369 | ;; The variable `ps-font-size' determines the size (in points) | |
370 | ;; of the font for ordinary text, when generating Postscript. | |
371 | ;; Its value is a float. | |
372 | ;; | |
373 | ;; Similarly, the variable `ps-header-font-family' determines | |
374 | ;; which font family is to be used for text in the header. | |
375 | ;; The variable `ps-header-font-size' determines the font size, | |
376 | ;; in points, for text in the header. | |
377 | ;; The variable `ps-header-title-font-size' determines the font size, | |
378 | ;; in points, for the top line of text in the header. | |
379 | ;; | |
380 | ;; | |
381 | ;; Adding a new font family | |
382 | ;; ------------------------ | |
383 | ;; | |
384 | ;; To use a new font family, you MUST first teach ps-print | |
385 | ;; this font, ie add its information to `ps-font-info-database', | |
386 | ;; otherwise ps-print cannot correctly place line and page breaks. | |
387 | ;; | |
388 | ;; For example, assuming `Helvetica' is unkown, | |
389 | ;; you first need to do the following ONLY ONCE: | |
390 | ;; | |
391 | ;; - create a new buffer | |
392 | ;; - generate the PostScript image to a file (C-u M-x ps-print-buffer) | |
393 | ;; - open this file and find the line: | |
394 | ;; `% 3 cm 20 cm moveto 10 /Courier ReportFontInfo showpage' | |
395 | ;; - delete the leading `%' (which is the Postscript comment character) | |
396 | ;; - replace in this line `Courier' by the new font (say `Helvetica') | |
397 | ;; to get the line: | |
398 | ;; `3 cm 20 cm moveto 10 /Helvetica ReportFontInfo showpage' | |
399 | ;; - send this file to the printer (or to ghostscript). | |
400 | ;; You should read the following on the output page: | |

402 | ;; For Helvetica 10 point, the line height is 11.56, the space width is 2.78 | |
403 | ;; and a crude estimate of average character width is 5.09243 | |
404 | ;; | |
405 | ;; - Add these values to the `ps-font-info-database': | |
406 | ;; (setq ps-font-info-database | |
407 | ;; (append | |
408 | ;; '((Helvetica ; the family name | |
409 | ;; "Helvetica" "Helvetica-Bold" "Helvetica-Oblique" "Helvetica-BoldOblique" | |
410 | ;; 10.0 11.56 2.78 5.09243)) | |
411 | ;; ps-font-info-database)) | |
412 | ;; - Now you can use this font family with any size: | |
413 | ;; (setq ps-font-family 'Helvetica) | |
414 | ;; - if you want to use this family in another emacs session, you must | |
415 | ;; put into your `~/.emacs': | |
416 | ;; (require 'ps-print) | |
417 | ;; (setq ps-font-info-database (append ...))) | |
418 | ;; if you don't want to load ps-print, you have to copy the whole value: | |
419 | ;; (setq ps-font-info-database '(<your stuff> <the standard stuff>)) | |
420 | ;; or, if you can wait until the `ps-print-hook' is implemented, do: | |
421 | ;; (add-hook 'ps-print-hook '(setq ps-font-info-database (append ...))) | |
422 | ;; This does not work yet, since there is no `ps-print-hook' yet. | |
423 | ;; | |
424 | ;; You can create new `mixed' font families like: | |
425 | ;; (my-mixed-family | |
426 | ;; "Courier-Bold" "Helvetica" | |
427 | ;; "Zapf-Chancery-MediumItalic" "NewCenturySchlbk-BoldItalic" | |
428 | ;; 10.0 10.55 6.0 6.0) | |
429 | ;; Now you can use your new font family with any size: | |
430 | ;; (setq ps-font-family 'my-mixed-family) | |
431 | ;; | |
432 | ;; You can get information on all the fonts resident in YOUR printer | |
433 | ;; by uncommenting the line: | |
434 | ;; % 3 cm 20 cm moveto ReportAllFontInfo showpage | |
435 | ;; | |
436 | ;; The postscript file should be sent to YOUR postscript printer. | |
437 | ;; If you send it to ghostscript or to another postscript printer, | |
438 | ;; you may get slightly different results. | |
439 | ;; Anyway, as ghostscript fonts are autoload, you won't get | |
440 | ;; much font info. | |

443 | ;; How Ps-Print Deals With Faces | |
444 | ;; ----------------------------- | |
12d89a2e | 445 | ;; |
bcc0d457 RS |
446 | ;; The ps-print-*-with-faces commands attempt to determine which faces |
447 | ;; should be printed in bold or italic, but their guesses aren't | |
448 | ;; always right. For example, you might want to map colors into faces | |
449 | ;; so that blue faces print in bold, and red faces in italic. | |
12d89a2e | 450 | ;; |
bcc0d457 RS |
451 | ;; It is possible to force ps-print to consider specific faces bold or |
452 | ;; italic, no matter what font they are displayed in, by setting the | |
453 | ;; variables `ps-bold-faces' and `ps-italic-faces'. These variables | |
454 | ;; contain lists of faces that ps-print should consider bold or | |
455 | ;; italic; to set them, put code like the following into your .emacs | |
456 | ;; file: | |
12d89a2e | 457 | ;; |
bcc0d457 RS |
458 | ;; (setq ps-bold-faces '(my-blue-face)) |
459 | ;; (setq ps-italic-faces '(my-red-face)) | |
460 | ;; | |
461 | ;; Faces like bold-italic that are both bold and italic should go in | |
462 | ;; *both* lists. | |
463 | ;; | |
464 | ;; Ps-print keeps internal lists of which fonts are bold and which are | |
465 | ;; italic; these lists are built the first time you invoke ps-print. | |
466 | ;; For the sake of efficiency, the lists are built only once; the same | |
467 | ;; lists are referred in later invocations of ps-print. | |
468 | ;; | |
469 | ;; Because these lists are built only once, it's possible for them to | |
470 | ;; get out of sync, if a face changes, or if new faces are added. To | |
471 | ;; get the lists back in sync, you can set the variable | |
472 | ;; `ps-build-face-reference' to t, and the lists will be rebuilt the | |
473 | ;; next time ps-print is invoked. | |
474 | ;; | |
475 | ;; | |
476 | ;; How Ps-Print Deals With Color | |
477 | ;; ----------------------------- | |
478 | ;; | |
479 | ;; Ps-print detects faces with foreground and background colors | |
480 | ;; defined and embeds color information in the PostScript image. | |
481 | ;; The default foreground and background colors are defined by the | |
482 | ;; variables `ps-default-fg' and `ps-default-bg'. | |
483 | ;; On black-and-white printers, colors are displayed in grayscale. | |
484 | ;; To turn off color output, set `ps-print-color-p' to nil. | |
485 | ;; | |
486 | ;; | |
487 | ;; Utilities | |
488 | ;; --------- | |
489 | ;; | |
490 | ;; Some tools are provided to help you customize your font setup. | |
491 | ;; | |
492 | ;; `ps-setup' returns (some part of) the current setup. | |
493 | ;; | |
494 | ;; To avoid wrapping too many lines, you may want to adjust the | |
495 | ;; left and right margins and the font size. On UN*X systems, do: | |
496 | ;; pr -t file | awk '{printf "%3d %s\n", length($0), $0}' | sort -r | head | |
497 | ;; to determine the longest lines of your file. | |
498 | ;; Then, the command `ps-line-lengths' will give you the correspondance | |
499 | ;; between a line length (number of characters) and the maximum font | |
500 | ;; size which doesn't wrap such a line with the current ps-print setup. | |
501 | ;; | |
502 | ;; The commands `ps-nb-pages-buffer' and `ps-nb-pages-region' display | |
503 | ;; the correspondance between a number of pages and the maximum font | |
504 | ;; size which allow the number of lines of the current buffer or of | |
505 | ;; its current region to fit in this number of pages. | |
506 | ;; Note: line folding is not taken into account in this process | |
507 | ;; and could change the results. | |
