12d89a2e | 46 | ;; About ps-print |
ef2cbb24 | 47 | ;; -------------- |
bcc0d457 | 48 | ;; |
ef2cbb24 RS |
49 | ;; This package provides printing of Emacs buffers on PostScript |
50 | ;; printers; the buffer's bold and italic text attributes are | |
51 | ;; preserved in the printer output. Ps-print is intended for use with | |
00aa16af RS |
52 | ;; Emacs 19 or Lucid Emacs, together with a fontifying package such as |
53 | ;; font-lock or hilit. | |
12d89a2e | 54 | ;; |
87a16a06 RS |
55 | ;; ps-print uses the same face attributes defined through font-lock or hilit |
56 | ;; to print a PostScript file, but some faces are better seeing on the screen | |
57 | ;; than on paper, specially when you have a black/white PostScript printer. | |
58 | ;; | |
59 | ;; ps-print allows a remap of face to another one that it is better to print, | |
60 | ;; for example, the face font-lock-comment-face (if you are using font-lock) | |
61 | ;; could have bold or italic attribute when printing, besides foreground color. | |
62 | ;; This remap improves printing look (see How Ps-Print Maps Faces). | |
63 | ;; | |
bcc0d457 | 64 | ;; |
12d89a2e | 65 | ;; Using ps-print |
ef2cbb24 | 66 | ;; -------------- |
ef2cbb24 | 67 | ;; |
12d89a2e RS |
68 | ;; The Commands |
69 | ;; | |
70 | ;; Ps-print provides eight commands for generating PostScript images | |
71 | ;; of Emacs buffers: | |
72 | ;; | |
73 | ;; ps-print-buffer | |
74 | ;; ps-print-buffer-with-faces | |
75 | ;; ps-print-region | |
76 | ;; ps-print-region-with-faces | |
77 | ;; ps-spool-buffer | |
78 | ;; ps-spool-buffer-with-faces | |
79 | ;; ps-spool-region | |
80 | ;; ps-spool-region-with-faces | |
81 | ;; | |
82 | ;; These commands all perform essentially the same function: they | |
83 | ;; generate PostScript images suitable for printing on a PostScript | |
84 | ;; printer or displaying with GhostScript. These commands are | |
85 | ;; collectively referred to as "ps-print- commands". | |
86 | ;; | |
87 | ;; The word "print" or "spool" in the command name determines when the | |
88 | ;; PostScript image is sent to the printer: | |
ef2cbb24 | 89 | ;; |
12d89a2e RS |
90 | ;; print - The PostScript image is immediately sent to the |
91 | ;; printer; | |
ef2cbb24 | 92 | ;; |
12d89a2e RS |
93 | ;; spool - The PostScript image is saved temporarily in an |
94 | ;; Emacs buffer. Many images may be spooled locally | |
95 | ;; before printing them. To send the spooled images | |
bcc0d457 | 96 | ;; to the printer, use the command `ps-despool'. |
ef2cbb24 | 97 | ;; |
12d89a2e RS |
98 | ;; The spooling mechanism was designed for printing lots of small |
99 | ;; files (mail messages or netnews articles) to save paper that would | |
100 | ;; otherwise be wasted on banner pages, and to make it easier to find | |
101 | ;; your output at the printer (it's easier to pick up one 50-page | |
102 | ;; printout than to find 50 single-page printouts). | |
06fb6aab | 103 | ;; |
1061ff16 | 104 | ;; Ps-print has a hook in the `kill-emacs-hook' so that you won't |
a7acbbe4 | 105 | ;; accidentally quit from Emacs while you have unprinted PostScript |
12d89a2e RS |
106 | ;; waiting in the spool buffer. If you do attempt to exit with |
107 | ;; spooled PostScript, you'll be asked if you want to print it, and if | |
108 | ;; you decline, you'll be asked to confirm the exit; this is modeled | |
109 | ;; on the confirmation that Emacs uses for modified buffers. | |
110 | ;; | |
111 | ;; The word "buffer" or "region" in the command name determines how | |
112 | ;; much of the buffer is printed: | |
113 | ;; | |
114 | ;; buffer - Print the entire buffer. | |
115 | ;; | |
116 | ;; region - Print just the current region. | |
117 | ;; | |
118 | ;; The -with-faces suffix on the command name means that the command | |
119 | ;; will include font, color, and underline information in the | |
120 | ;; PostScript image, so the printed image can look as pretty as the | |
121 | ;; buffer. The ps-print- commands without the -with-faces suffix | |
122 | ;; don't include font, color, or underline information; images printed | |
123 | ;; with these commands aren't as pretty, but are faster to generate. | |
124 | ;; | |
125 | ;; Two ps-print- command examples: | |
126 | ;; | |
127 | ;; ps-print-buffer - print the entire buffer, | |
128 | ;; without font, color, or | |
129 | ;; underline information, and | |
130 | ;; send it immediately to the | |
131 | ;; printer. | |
132 | ;; | |
133 | ;; ps-spool-region-with-faces - print just the current region; | |
134 | ;; include font, color, and | |
135 | ;; underline information, and | |
136 | ;; spool the image in Emacs to | |
137 | ;; send to the printer later. | |
138 | ;; | |
139 | ;; | |
140 | ;; Invoking Ps-Print | |
bcc0d457 | 141 | ;; ----------------- |
ef2cbb24 | 142 | ;; |
12d89a2e | 143 | ;; To print your buffer, type |
ef2cbb24 | 144 | ;; |
12d89a2e | 145 | ;; M-x ps-print-buffer |
ef2cbb24 | 146 | ;; |
12d89a2e RS |
147 | ;; or substitute one of the other seven ps-print- commands. The |
148 | ;; command will generate the PostScript image and print or spool it as | |
149 | ;; specified. By giving the command a prefix argument | |
150 | ;; | |
151 | ;; C-u M-x ps-print-buffer | |
152 | ;; | |
153 | ;; it will save the PostScript image to a file instead of sending it | |
154 | ;; to the printer; you will be prompted for the name of the file to | |
155 | ;; save the image to. The prefix argument is ignored by the commands | |
156 | ;; that spool their images, but you may save the spooled images to a | |
bcc0d457 | 157 | ;; file by giving a prefix argument to `ps-despool': |
12d89a2e RS |
158 | ;; |
159 | ;; C-u M-x ps-despool | |
160 | ;; | |
bcc0d457 | 161 | ;; When invoked this way, `ps-despool' will prompt you for the name of |
12d89a2e RS |
162 | ;; the file to save to. |
163 | ;; | |
bcc0d457 RS |
164 | ;; Any of the `ps-print-' commands can be bound to keys; I recommend |
165 | ;; binding `ps-spool-buffer-with-faces', `ps-spool-region-with-faces', | |
166 | ;; and `ps-despool'. Here are the bindings I use on my Sun 4 keyboard: | |
12d89a2e RS |
167 | ;; |
168 | ;; (global-set-key 'f22 'ps-spool-buffer-with-faces) ;f22 is prsc | |
ef2cbb24 RS |
169 | ;; (global-set-key '(shift f22) 'ps-spool-region-with-faces) |
170 | ;; (global-set-key '(control f22) 'ps-despool) | |

173 | ;; The Printer Interface | |
bcc0d457 | 174 | ;; --------------------- |
12d89a2e | 175 | ;; |
bcc0d457 | 176 | ;; The variables `ps-lpr-command' and `ps-lpr-switches' determine what |
12d89a2e | 177 | ;; command is used to send the PostScript images to the printer, and |
bcc0d457 RS |
178 | ;; what arguments to give the command. These are analogous to |
179 | ;; `lpr-command' and `lpr-switches'. | |
87a16a06 | 180 | ;; |
bcc0d457 RS |
181 | ;; Make sure that they contain appropriate values for your system; |
182 | ;; see the usage notes below and the documentation of these variables. | |
183 | ;; | |
184 | ;; NOTE: `ps-lpr-command' and `ps-lpr-switches' take their initial values | |
185 | ;; from the variables `lpr-command' and `lpr-switches'. If you have | |
186 | ;; `lpr-command' set to invoke a pretty-printer such as `enscript', | |
187 | ;; then ps-print won't work properly. `ps-lpr-command' must name | |
12d89a2e RS |
188 | ;; a program that does not format the files it prints. |
189 | ;; | |
190 | ;; | |
bcc0d457 RS |
191 | ;; The Page Layout |
192 | ;; --------------- | |
12d89a2e | 193 | ;; |
bcc0d457 RS |
194 | ;; All dimensions are floats in PostScript points. |
195 | ;; 1 inch == 2.54 cm == 72 points | |
196 | ;; 1 cm == (/ 1 2.54) inch == (/ 72 2.54) points | |
12d89a2e | 197 | ;; |
bcc0d457 RS |
198 | ;; The variable `ps-paper-type' determines the size of paper ps-print |
199 | ;; formats for; it should contain one of the symbols: | |
200 | ;; `a4' `a3' `letter' `legal' `letter-small' `tabloid' | |
201 | ;; `ledger' `statement' `executive' `a4small' `b4' `b5' | |
12d89a2e | 202 | ;; |
bcc0d457 RS |
203 | ;; The variable `ps-landscape-mode' determines the orientation |
204 | ;; of the printing on the page: | |
205 | ;; nil means `portrait' mode, non-nil means `landscape' mode. | |
206 | ;; There is no oblique mode yet, though this is easy to do in ps. | |
87a16a06 | 207 | ;; |
bcc0d457 RS |
208 | ;; In landscape mode, the text is NOT scaled: you may print 70 lines |
209 | ;; in portrait mode and only 50 lignes in landscape mode. | |
210 | ;; The margins represent margins in the printed paper: | |
211 | ;; the top margin is the margin between the top of the page | |
212 | ;; and the printed header, whatever the orientation is. | |
043620f4 | 213 | ;; |
bcc0d457 RS |
214 | ;; The variable `ps-number-of-columns' determines the number of columns |
215 | ;; both in landscape and portrait mode. | |
216 | ;; You can use: | |
217 | ;; - (the standard) one column portrait mode | |
218 | ;; - (my favorite) two columns landscape mode (which spares trees) | |
219 | ;; but also | |
220 | ;; - one column landscape mode for files with very long lines. | |
221 | ;; - multi-column portrait or landscape mode | |

224 | ;; Horizontal layout |
225 | ;; ----------------- | |
12d89a2e | 226 | ;; |
bcc0d457 RS |
227 | ;; The horizontal layout is determined by the variables |
228 | ;; `ps-left-margin' `ps-inter-column' `ps-right-margin' | |
229 | ;; as follows: | |
12d89a2e | 230 | ;; |

234 | ;; | | | | | | | | | |
235 | ;; ------------------------------------------ | |
12d89a2e | 236 | ;; |
bcc0d457 RS |
237 | ;; If `ps-number-of-columns' is 1, `ps-inter-column' is not relevant. |
238 | ;; Usually, lm = rm > 0 and ic = lm | |
239 | ;; If (ic < 0), the text of adjacent columns can overlap. | |
12d89a2e | 240 | ;; |
12d89a2e | 241 | ;; |
bcc0d457 RS |
242 | ;; Vertical layout |
243 | ;; --------------- | |
244 | ;; | |
245 | ;; The vertical layout is determined by the variables | |
246 | ;; `ps-bottom-margin' `ps-top-margin' `ps-header-offset' | |
247 | ;; as follows: | |
248 | ;; | |
249 | ;; |--------| |--------| | |

263 | ;; If `ps-print-header' is nil, `ps-header-offset' is not relevant. | |
264 | ;; The margins represent margins in the printed paper: | |

266 | ;; and the printed header, whatever the orientation is. | |
12d89a2e RS |
267 | ;; |
268 | ;; | |
269 | ;; Headers | |
bcc0d457 | 270 | ;; ------- |
12d89a2e | 271 | ;; |
bcc0d457 | 272 | ;; Ps-print can print headers at the top of each column; the default |
12d89a2e RS |
273 | ;; headers contain the following four items: on the left, the name of |
274 | ;; the buffer and, if the buffer is visiting a file, the file's | |
bcc0d457 RS |
275 | ;; directory; on the right, the page number and date of printing. |
276 | ;; The default headers look something like this: | |
12d89a2e RS |
277 | ;; |
278 | ;; ps-print.el 1/21 | |
279 | ;; /home/jct/emacs-lisp/ps/new 94/12/31 | |
06fb6aab | 280 | ;; |
12d89a2e | 281 | ;; When printing on duplex printers, left and right are reversed so |
bcc0d457 | 282 | ;; that the page numbers are toward the outside (cf. `ps-spool-duplex'). |
12d89a2e | 283 | ;; |
bcc0d457 RS |
284 | ;; Headers are configurable: |
285 | ;; To turn them off completely, set `ps-print-header' to nil. | |
286 | ;; To turn off the header's gaudy framing box, | |
287 | ;; set `ps-print-header-frame' to nil. | |
288 | ;; | |
289 | ;; The font family and size of text in the header are determined | |
06fb6aab | 290 | ;; by the variables `ps-header-font-family', `ps-header-font-size' and |
bcc0d457 RS |
291 | ;; `ps-header-title-font-size' (see below). |
292 | ;; | |
293 | ;; The variable `ps-header-line-pad' determines the portion of a header | |
294 | ;; title line height to insert between the header frame and the text | |
295 | ;; it contains, both in the vertical and horizontal directions: | |
296 | ;; .5 means half a line. | |
297 | ||
298 | ;; Page numbers are printed in `n/m' format, indicating page n of m pages; | |
299 | ;; to omit the total page count and just print the page number, | |
300 | ;; set `ps-show-n-of-n' to nil. | |
12d89a2e RS |
301 | ;; |
302 | ;; The amount of information in the header can be changed by changing | |
bcc0d457 | 303 | ;; the number of lines. To show less, set `ps-header-lines' to 1, and |
12d89a2e | 304 | ;; the header will show only the buffer name and page number. To show |
bcc0d457 | 305 | ;; more, set `ps-header-lines' to 3, and the header will show the time of |
12d89a2e RS |
306 | ;; printing below the date. |
307 | ;; | |
308 | ;; To change the content of the headers, change the variables | |
bcc0d457 RS |
309 | ;; `ps-left-header' and `ps-right-header'. |
310 | ;; These variables are lists, specifying top-to-bottom the text | |
311 | ;; to display on the left or right side of the header. | |
312 | ;; Each element of the list should be a string or a symbol. | |
313 | ;; Strings are inserted directly into the PostScript arrays, | |
314 | ;; and should contain the PostScript string delimiters '(' and ')'. | |
12d89a2e RS |
315 | ;; |
316 | ;; Symbols in the header format lists can either represent functions | |
317 | ;; or variables. Functions are called, and should return a string to | |
318 | ;; show in the header. Variables should contain strings to display in | |
319 | ;; the header. In either case, function or variable, the PostScript | |
a7acbbe4 | 320 | ;; string delimiters are added by ps-print, and should not be part of |
12d89a2e RS |
321 | ;; the returned value. |
322 | ;; | |
323 | ;; Here's an example: say we want the left header to display the text | |
324 | ;; | |
325 | ;; Moe | |
326 | ;; Larry | |
327 | ;; Curly | |
328 | ;; | |
329 | ;; where we have a function to return "Moe" | |
330 | ;; | |
331 | ;; (defun moe-func () | |
332 | ;; "Moe") | |
333 | ;; | |
334 | ;; a variable specifying "Larry" | |
335 | ;; | |
336 | ;; (setq larry-var "Larry") | |
337 | ;; | |
bcc0d457 | 338 | ;; and a literal for "Curly". Here's how `ps-left-header' should be |
12d89a2e RS |
339 | ;; set: |
340 | ;; | |
341 | ;; (setq ps-left-header (list 'moe-func 'larry-var "(Curly)")) | |
342 | ;; | |
343 | ;; Note that Curly has the PostScript string delimiters inside his | |
bcc0d457 | 344 | ;; quotes -- those aren't misplaced lisp delimiters! |
87a16a06 | 345 | ;; |
bcc0d457 RS |
346 | ;; Without them, PostScript would attempt to call the undefined |
347 | ;; function Curly, which would result in a PostScript error. | |
87a16a06 | 348 | ;; |
bcc0d457 RS |
349 | ;; Since most printers don't report PostScript errors except by |
350 | ;; aborting the print job, this kind of error can be hard to track down. | |
87a16a06 | 351 | ;; |
bcc0d457 | 352 | ;; Consider yourself warned! |

355 | ;; Duplex Printers | |
bcc0d457 | 356 | ;; --------------- |
12d89a2e RS |
357 | ;; |
358 | ;; If you have a duplex-capable printer (one that prints both sides of | |
bcc0d457 RS |
359 | ;; the paper), set `ps-spool-duplex' to t. |
360 | ;; Ps-print will insert blank pages to make sure each buffer starts | |
361 | ;; on the correct side of the paper. | |
362 | ;; Don't forget to set `ps-lpr-switches' to select duplex printing | |
363 | ;; for your printer. | |

366 | ;; Control And 8-bit Characters |
367 | ;; ---------------------------- | |
368 | ;; | |
369 | ;; The variable `ps-print-control-characters' specifies whether you want to see | |
370 | ;; a printable form for control and 8-bit characters, that is, instead of | |
371 | ;; sending, for example, a ^D (\005) to printer, it is sent the string "^D". | |
372 | ;; | |
373 | ;; Valid values for `ps-print-control-characters' are: | |
374 | ;; | |
375 | ;; '8-bit printable form for control and 8-bit characters | |
376 | ;; (characters from \000 to \037 and \177 to \377). | |
377 | ;; 'control-8-bit printable form for control and *control* 8-bit characters | |
378 | ;; (characters from \000 to \037 and \177 to \237). | |
379 | ;; 'control printable form for control character | |
380 | ;; (characters from \000 to \037 and \177). | |
381 | ;; nil raw character (no printable form). | |

426 | ;; Font managing |
427 | ;; ------------- | |
428 | ;; | |
429 | ;; Ps-print now knows rather precisely some fonts: | |
430 | ;; the variable `ps-font-info-database' contains information | |
431 | ;; for a list of font families (currently mainly `Courier' `Helvetica' | |
432 | ;; `Times' `Palatino' `Helvetica-Narrow' `NewCenturySchlbk'). | |
433 | ;; Each font family contains the font names for standard, bold, italic | |
434 | ;; and bold-italic characters, a reference size (usually 10) and the | |
435 | ;; corresponding line height, width of a space and average character width. | |
06fb6aab | 436 | ;; |
bcc0d457 RS |
437 | ;; The variable `ps-font-family' determines which font family |
438 | ;; is to be used for ordinary text. | |
439 | ;; If its value does not correspond to a known font family, | |
440 | ;; an error message is printed into the `*Messages*' buffer, | |
441 | ;; which lists the currently available font families. | |
442 | ;; | |
443 | ;; The variable `ps-font-size' determines the size (in points) | |
444 | ;; of the font for ordinary text, when generating Postscript. | |
445 | ;; Its value is a float. | |
446 | ;; | |
447 | ;; Similarly, the variable `ps-header-font-family' determines | |
448 | ;; which font family is to be used for text in the header. | |
449 | ;; The variable `ps-header-font-size' determines the font size, | |
450 | ;; in points, for text in the header. | |
451 | ;; The variable `ps-header-title-font-size' determines the font size, | |
452 | ;; in points, for the top line of text in the header. | |
453 | ;; | |
454 | ;; | |
455 | ;; Adding a new font family | |
456 | ;; ------------------------ | |
457 | ;; | |
458 | ;; To use a new font family, you MUST first teach ps-print | |
87a16a06 | 459 | ;; this font, i.e., add its information to `ps-font-info-database', |
bcc0d457 RS |
460 | ;; otherwise ps-print cannot correctly place line and page breaks. |
461 | ;; | |
87a16a06 | 462 | ;; For example, assuming `Helvetica' is unknown, |
bcc0d457 RS |
463 | ;; you first need to do the following ONLY ONCE: |
464 | ;; | |
465 | ;; - create a new buffer | |
466 | ;; - generate the PostScript image to a file (C-u M-x ps-print-buffer) | |
467 | ;; - open this file and find the line: | |
468 | ;; `% 3 cm 20 cm moveto 10 /Courier ReportFontInfo showpage' | |
a18ed129 | 469 | ;; - delete the leading `%' (which is the PostScript comment character) |
bcc0d457 RS |
470 | ;; - replace in this line `Courier' by the new font (say `Helvetica') |
471 | ;; to get the line: | |
472 | ;; `3 cm 20 cm moveto 10 /Helvetica ReportFontInfo showpage' | |
473 | ;; - send this file to the printer (or to ghostscript). | |
474 | ;; You should read the following on the output page: | |
475 | ;; | |
476 | ;; For Helvetica 10 point, the line height is 11.56, the space width is 2.78 | |
477 | ;; and a crude estimate of average character width is 5.09243 | |
478 | ;; | |
479 | ;; - Add these values to the `ps-font-info-database': | |
480 | ;; (setq ps-font-info-database | |
481 | ;; (append | |
482 | ;; '((Helvetica ; the family name | |
483 | ;; "Helvetica" "Helvetica-Bold" "Helvetica-Oblique" "Helvetica-BoldOblique" | |
484 | ;; 10.0 11.56 2.78 5.09243)) | |
485 | ;; ps-font-info-database)) | |
486 | ;; - Now you can use this font family with any size: | |
487 | ;; (setq ps-font-family 'Helvetica) | |
488 | ;; - if you want to use this family in another emacs session, you must | |
489 | ;; put into your `~/.emacs': | |
490 | ;; (require 'ps-print) | |
491 | ;; (setq ps-font-info-database (append ...))) | |
492 | ;; if you don't want to load ps-print, you have to copy the whole value: | |
493 | ;; (setq ps-font-info-database '(<your stuff> <the standard stuff>)) | |
494 | ;; or, if you can wait until the `ps-print-hook' is implemented, do: | |
495 | ;; (add-hook 'ps-print-hook '(setq ps-font-info-database (append ...))) | |
496 | ;; This does not work yet, since there is no `ps-print-hook' yet. | |
497 | ;; | |
498 | ;; You can create new `mixed' font families like: | |
499 | ;; (my-mixed-family | |
500 | ;; "Courier-Bold" "Helvetica" | |
501 | ;; "Zapf-Chancery-MediumItalic" "NewCenturySchlbk-BoldItalic" | |
502 | ;; 10.0 10.55 6.0 6.0) | |
503 | ;; Now you can use your new font family with any size: | |
504 | ;; (setq ps-font-family 'my-mixed-family) | |
505 | ;; | |
506 | ;; You can get information on all the fonts resident in YOUR printer | |
507 | ;; by uncommenting the line: | |
508 | ;; % 3 cm 20 cm moveto ReportAllFontInfo showpage | |
509 | ;; | |
a18ed129 RS |
510 | ;; The PostScript file should be sent to YOUR PostScript printer. |
511 | ;; If you send it to ghostscript or to another PostScript printer, | |
bcc0d457 RS |
512 | ;; you may get slightly different results. |
513 | ;; Anyway, as ghostscript fonts are autoload, you won't get | |
514 | ;; much font info. | |
515 | ;; | |
516 | ;; | |
517 | ;; How Ps-Print Deals With Faces | |
518 | ;; ----------------------------- | |
12d89a2e | 519 | ;; |
bcc0d457 RS |
520 | ;; The ps-print-*-with-faces commands attempt to determine which faces |
521 | ;; should be printed in bold or italic, but their guesses aren't | |
522 | ;; always right. For example, you might want to map colors into faces | |
523 | ;; so that blue faces print in bold, and red faces in italic. | |
12d89a2e | 524 | ;; |
857686a6 RS |
525 | ;; It is possible to force ps-print to consider specific faces bold, |
526 | ;; italic or underline, no matter what font they are displayed in, by setting | |
527 | ;; the variables `ps-bold-faces', `ps-italic-faces' and `ps-underlined-faces'. | |
528 | ;; These variables contain lists of faces that ps-print should consider bold, | |
529 | ;; italic or underline; to set them, put code like the following into your | |
530 | ;; .emacs file: | |
12d89a2e | 531 | ;; |
bcc0d457 RS |
532 | ;; (setq ps-bold-faces '(my-blue-face)) |
533 | ;; (setq ps-italic-faces '(my-red-face)) | |
857686a6 | 534 | ;; (setq ps-underlined-faces '(my-green-face)) |
bcc0d457 RS |
535 | ;; |
536 | ;; Faces like bold-italic that are both bold and italic should go in | |
537 | ;; *both* lists. | |
538 | ;; | |
539 | ;; Ps-print keeps internal lists of which fonts are bold and which are | |
540 | ;; italic; these lists are built the first time you invoke ps-print. | |
541 | ;; For the sake of efficiency, the lists are built only once; the same | |
542 | ;; lists are referred in later invocations of ps-print. | |
543 | ;; | |
544 | ;; Because these lists are built only once, it's possible for them to | |
545 | ;; get out of sync, if a face changes, or if new faces are added. To | |
546 | ;; get the lists back in sync, you can set the variable | |
547 | ;; `ps-build-face-reference' to t, and the lists will be rebuilt the | |
857686a6 RS |
548 | ;; next time ps-print is invoked. If you need that the lists always be |
549 | ;; rebuilt when ps-print is invoked, set the variable | |
550 | ;; `ps-always-build-face-reference' to t. | |
bcc0d457 RS |
551 | ;; |
552 | ;; | |
553 | ;; How Ps-Print Deals With Color | |
554 | ;; ----------------------------- | |
555 | ;; | |
556 | ;; Ps-print detects faces with foreground and background colors | |
557 | ;; defined and embeds color information in the PostScript image. | |
558 | ;; The default foreground and background colors are defined by the | |
559 | ;; variables `ps-default-fg' and `ps-default-bg'. | |
560 | ;; On black-and-white printers, colors are displayed in grayscale. | |
561 | ;; To turn off color output, set `ps-print-color-p' to nil. | |
562 | ;; | |
563 | ;; | |
87a16a06 RS |
564 | ;; How Ps-Print Maps Faces |
565 | ;; ----------------------- | |
566 | ;; | |
567 | ;; As ps-print uses PostScript to print buffers, it is possible to have | |
568 | ;; other attributes associated with faces. So the new attributes used | |
569 | ;; by ps-print are: | |
570 | ;; | |
571 | ;; strikeout - like underline, but the line is in middle of text. | |
572 | ;; overline - like underline, but the line is over the text. | |
573 | ;; shadow - text will have a shadow. | |
574 | ;; box - text will be surrounded by a box. | |
a18ed129 | 575 | ;; outline - print characters as hollow outlines. |
87a16a06 | 576 | ;; |
06fb6aab | 577 | ;; See the documentation for `ps-extend-face'. |
87a16a06 RS |
578 | ;; |
579 | ;; Let's, for example, remap font-lock-keyword-face to another foreground color | |
580 | ;; and bold attribute: | |
581 | ;; | |
a18ed129 | 582 | ;; (ps-extend-face '(font-lock-keyword-face "RoyalBlue" nil bold) 'MERGE) |
87a16a06 | 583 | ;; |
6c8f2753 RS |
584 | ;; If you want to use a new face, define it first with `defface', |
585 | ;; and then call `ps-extend-face' to specify how to print it. | |
586 | ;; | |
87a16a06 RS |
587 | ;; |
588 | ;; How Ps-Print Has A Text And/Or Image On Background | |
589 | ;; -------------------------------------------------- | |
590 | ;; | |
591 | ;; Ps-print can print texts and/or EPS PostScript images on background; it is | |
592 | ;; possible to define the following text attributes: font name, font size, | |
593 | ;; initial position, angle, gray scale and pages to print. | |
594 | ;; | |
595 | ;; It has the following EPS PostScript images attributes: file name containing | |
596 | ;; the image, initial position, X and Y scales, angle and pages to print. | |
597 | ;; | |
598 | ;; See documentation for `ps-print-background-text' and | |
599 | ;; `ps-print-background-image'. | |
600 | ;; | |
601 | ;; For example, if we wish to print text "preliminary" on all pages and text | |
602 | ;; "special" on page 5 and from page 11 to page 17, we could specify: | |
603 | ;; | |
604 | ;; (setq ps-print-background-text | |
605 | ;; '(("preliminary") | |
606 | ;; ("special" | |
607 | ;; "LeftMargin" "BottomMargin PrintHeight add" ; X and Y position | |
608 | ;; ; (upper left corner) | |
609 | ;; nil nil nil | |
610 | ;; "PrintHeight neg PrintWidth atan" ; angle | |
611 | ;; 5 (11 . 17)) ; page list | |
612 | ;; )) | |
613 | ;; | |
614 | ;; Similarly, we could print image "~/images/EPS-image1.ps" on all pages and | |
615 | ;; image "~/images/EPS-image2.ps" on page 5 and from page 11 to page 17, we | |
616 | ;; specify: | |
617 | ;; | |
618 | ;; (setq ps-print-background-image | |
619 | ;; '(("~/images/EPS-image1.ps" | |
620 | ;; "LeftMargin" "BottomMargin") ; X and Y position (lower left corner) | |
621 | ;; ("~/images/EPS-image2.ps" | |
622 | ;; "LeftMargin" "BottomMargin PrintHeight 2 div add" ; X and Y position | |
623 | ;; ; (upper left corner) | |
624 | ;; nil nil nil | |
625 | ;; 5 (11 . 17)) ; page list | |
626 | ;; )) | |
627 | ;; | |
628 | ;; If it is not possible to read (or does not exist) an image file, that file | |
629 | ;; is ignored. | |
630 | ;; | |
631 | ;; The printing order is: | |
632 | ;; | |
633 | ;; 1. Print zebra stripes | |
634 | ;; 2. Print background texts that it should be on all pages | |
635 | ;; 3. Print background images that it should be on all pages | |
636 | ;; 4. Print background texts only for current page (if any) | |
637 | ;; 5. Print background images only for current page (if any) | |
638 | ;; 6. Print header | |
a18ed129 | 639 | ;; 7. Print buffer text (with faces, if specified) and line number |

642 | ;; Utilities |
643 | ;; --------- | |
644 | ;; | |
645 | ;; Some tools are provided to help you customize your font setup. | |
646 | ;; | |
647 | ;; `ps-setup' returns (some part of) the current setup. | |
648 | ;; | |
649 | ;; To avoid wrapping too many lines, you may want to adjust the | |
650 | ;; left and right margins and the font size. On UN*X systems, do: | |
651 | ;; pr -t file | awk '{printf "%3d %s\n", length($0), $0}' | sort -r | head | |
652 | ;; to determine the longest lines of your file. | |
87a16a06 | 653 | ;; Then, the command `ps-line-lengths' will give you the correspondence |
bcc0d457 RS |
654 | ;; between a line length (number of characters) and the maximum font |
655 | ;; size which doesn't wrap such a line with the current ps-print setup. | |
656 | ;; | |
657 | ;; The commands `ps-nb-pages-buffer' and `ps-nb-pages-region' display | |
87a16a06 | 658 | ;; the correspondence between a number of pages and the maximum font |
bcc0d457 RS |
659 | ;; size which allow the number of lines of the current buffer or of |
660 | ;; its current region to fit in this number of pages. | |
