12d89a2e | 48 | ;; About ps-print |
ef2cbb24 | 49 | ;; -------------- |
bcc0d457 | 50 | ;; |
ef2cbb24 RS |
51 | ;; This package provides printing of Emacs buffers on PostScript |
52 | ;; printers; the buffer's bold and italic text attributes are | |
d3ab8dac | 53 | ;; preserved in the printer output. ps-print is intended for use with |
00aa16af RS |
54 | ;; Emacs 19 or Lucid Emacs, together with a fontifying package such as |
55 | ;; font-lock or hilit. | |
12d89a2e | 56 | ;; |
87a16a06 RS |
57 | ;; ps-print uses the same face attributes defined through font-lock or hilit |
58 | ;; to print a PostScript file, but some faces are better seeing on the screen | |
59 | ;; than on paper, specially when you have a black/white PostScript printer. | |
60 | ;; | |
61 | ;; ps-print allows a remap of face to another one that it is better to print, | |
62 | ;; for example, the face font-lock-comment-face (if you are using font-lock) | |
63 | ;; could have bold or italic attribute when printing, besides foreground color. | |
64 | ;; This remap improves printing look (see How Ps-Print Maps Faces). | |
65 | ;; | |
bcc0d457 | 66 | ;; |
12d89a2e | 67 | ;; Using ps-print |
ef2cbb24 | 68 | ;; -------------- |
ef2cbb24 | 69 | ;; |
d3ab8dac | 70 | ;; ps-print provides eight commands for generating PostScript images |
12d89a2e RS |
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 | ;; |
d3ab8dac | 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) | |

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 | ;; | |
d3ab8dac KH |
184 | ;; The variable `ps-printer-name' determine the name of a local printer for |
185 | ;; printing PostScript files. | |
186 | ;; | |
bcc0d457 RS |
187 | ;; NOTE: `ps-lpr-command' and `ps-lpr-switches' take their initial values |
188 | ;; from the variables `lpr-command' and `lpr-switches'. If you have | |
189 | ;; `lpr-command' set to invoke a pretty-printer such as `enscript', | |
190 | ;; then ps-print won't work properly. `ps-lpr-command' must name | |
12d89a2e | 191 | ;; a program that does not format the files it prints. |
d3ab8dac KH |
192 | ;; `ps-printer-name' takes its initial value from the variable |

bcc0d457 RS |
199 | ;; All dimensions are floats in PostScript points. |
200 | ;; 1 inch == 2.54 cm == 72 points | |
201 | ;; 1 cm == (/ 1 2.54) inch == (/ 72 2.54) points | |
12d89a2e | 202 | ;; |
bcc0d457 RS |
203 | ;; The variable `ps-paper-type' determines the size of paper ps-print |
204 | ;; formats for; it should contain one of the symbols: | |
205 | ;; `a4' `a3' `letter' `legal' `letter-small' `tabloid' | |
206 | ;; `ledger' `statement' `executive' `a4small' `b4' `b5' | |
12d89a2e | 207 | ;; |
bcc0d457 RS |
208 | ;; The variable `ps-landscape-mode' determines the orientation |
209 | ;; of the printing on the page: | |
210 | ;; nil means `portrait' mode, non-nil means `landscape' mode. | |
211 | ;; There is no oblique mode yet, though this is easy to do in ps. | |
87a16a06 | 212 | ;; |
bcc0d457 RS |
213 | ;; In landscape mode, the text is NOT scaled: you may print 70 lines |
214 | ;; in portrait mode and only 50 lignes in landscape mode. | |
215 | ;; The margins represent margins in the printed paper: | |
216 | ;; the top margin is the margin between the top of the page | |
217 | ;; and the printed header, whatever the orientation is. | |
043620f4 | 218 | ;; |
bcc0d457 RS |
219 | ;; The variable `ps-number-of-columns' determines the number of columns |
220 | ;; both in landscape and portrait mode. | |
221 | ;; You can use: | |
222 | ;; - (the standard) one column portrait mode | |
223 | ;; - (my favorite) two columns landscape mode (which spares trees) | |
224 | ;; but also | |
225 | ;; - one column landscape mode for files with very long lines. | |
226 | ;; - multi-column portrait or landscape mode | |

273 | ;; | |
274 | ;; Headers | |
bcc0d457 | 275 | ;; ------- |
12d89a2e | 276 | ;; |
d3ab8dac | 277 | ;; ps-print can print headers at the top of each column or at the top |
12b88fff RS |
278 | ;; of each page; the default headers contain the following four items: |
279 | ;; on the left, the name of the buffer and, if the buffer is visiting | |
280 | ;; a file, the file's directory; on the right, the page number and | |
281 | ;; date of printing. The default headers look something like this: | |
12d89a2e RS |
282 | ;; |
283 | ;; ps-print.el 1/21 | |
284 | ;; /home/jct/emacs-lisp/ps/new 94/12/31 | |
06fb6aab | 285 | ;; |
12d89a2e | 286 | ;; When printing on duplex printers, left and right are reversed so |
bcc0d457 | 287 | ;; that the page numbers are toward the outside (cf. `ps-spool-duplex'). |
12d89a2e | 288 | ;; |
bcc0d457 RS |
289 | ;; Headers are configurable: |
290 | ;; To turn them off completely, set `ps-print-header' to nil. | |
291 | ;; To turn off the header's gaudy framing box, | |
292 | ;; set `ps-print-header-frame' to nil. | |
293 | ;; | |
12b88fff RS |
294 | ;; To print only one header at the top of each page, |
295 | ;; set `ps-print-only-one-header' to t. | |
296 | ;; | |
bcc0d457 | 297 | ;; The font family and size of text in the header are determined |
06fb6aab | 298 | ;; by the variables `ps-header-font-family', `ps-header-font-size' and |
bcc0d457 RS |
299 | ;; `ps-header-title-font-size' (see below). |
300 | ;; | |
301 | ;; The variable `ps-header-line-pad' determines the portion of a header | |
302 | ;; title line height to insert between the header frame and the text | |
303 | ;; it contains, both in the vertical and horizontal directions: | |
304 | ;; .5 means half a line. | |
305 | ||
306 | ;; Page numbers are printed in `n/m' format, indicating page n of m pages; | |
307 | ;; to omit the total page count and just print the page number, | |
308 | ;; set `ps-show-n-of-n' to nil. | |
12d89a2e RS |
309 | ;; |
310 | ;; The amount of information in the header can be changed by changing | |
bcc0d457 | 311 | ;; the number of lines. To show less, set `ps-header-lines' to 1, and |
12d89a2e | 312 | ;; the header will show only the buffer name and page number. To show |
bcc0d457 | 313 | ;; more, set `ps-header-lines' to 3, and the header will show the time of |
12d89a2e RS |
314 | ;; printing below the date. |
315 | ;; | |
316 | ;; To change the content of the headers, change the variables | |
bcc0d457 RS |
317 | ;; `ps-left-header' and `ps-right-header'. |
318 | ;; These variables are lists, specifying top-to-bottom the text | |
319 | ;; to display on the left or right side of the header. | |
320 | ;; Each element of the list should be a string or a symbol. | |
321 | ;; Strings are inserted directly into the PostScript arrays, | |
322 | ;; and should contain the PostScript string delimiters '(' and ')'. | |
12d89a2e RS |
323 | ;; |
324 | ;; Symbols in the header format lists can either represent functions | |
325 | ;; or variables. Functions are called, and should return a string to | |
326 | ;; show in the header. Variables should contain strings to display in | |
327 | ;; the header. In either case, function or variable, the PostScript | |
a7acbbe4 | 328 | ;; string delimiters are added by ps-print, and should not be part of |
12d89a2e RS |
329 | ;; the returned value. |
330 | ;; | |
331 | ;; Here's an example: say we want the left header to display the text | |
332 | ;; | |
333 | ;; Moe | |
334 | ;; Larry | |
335 | ;; Curly | |
336 | ;; | |
337 | ;; where we have a function to return "Moe" | |
338 | ;; | |
339 | ;; (defun moe-func () | |
340 | ;; "Moe") | |
341 | ;; | |
342 | ;; a variable specifying "Larry" | |
343 | ;; | |
344 | ;; (setq larry-var "Larry") | |
345 | ;; | |
bcc0d457 | 346 | ;; and a literal for "Curly". Here's how `ps-left-header' should be |
12d89a2e RS |
347 | ;; set: |
348 | ;; | |
349 | ;; (setq ps-left-header (list 'moe-func 'larry-var "(Curly)")) | |
350 | ;; | |
351 | ;; Note that Curly has the PostScript string delimiters inside his | |
bcc0d457 | 352 | ;; quotes -- those aren't misplaced lisp delimiters! |
87a16a06 | 353 | ;; |
bcc0d457 RS |
354 | ;; Without them, PostScript would attempt to call the undefined |
355 | ;; function Curly, which would result in a PostScript error. | |
87a16a06 | 356 | ;; |
bcc0d457 RS |
357 | ;; Since most printers don't report PostScript errors except by |
358 | ;; aborting the print job, this kind of error can be hard to track down. | |
87a16a06 | 359 | ;; |
bcc0d457 | 360 | ;; Consider yourself warned! |

363 | ;; PostScript Prologue Header |
364 | ;; -------------------------- | |
365 | ;; | |
366 | ;; It is possible to add PostScript prologue header comments besides that | |
367 | ;; ps-print generates by setting the variable `ps-print-prologue-header'. | |
368 | ;; | |
369 | ;; `ps-print-prologue-header' may be a string or a symbol function which | |
370 | ;; returns a string. Note that this string is inserted on PostScript prologue | |
371 | ;; header section which is used to define some document characteristic through | |
372 | ;; PostScript special comments, like "%%Requirements: jog\n". | |
373 | ;; | |
374 | ;; By default `ps-print-prologue-header' is nil. | |
375 | ;; | |
376 | ;; ps-print always inserts the %%Requirements: comment, so if you need to insert | |
377 | ;; more requirements put them first in `ps-print-prologue-header' using the | |
378 | ;; "%%+" comment. For example, if you need to set numcopies to 3 and jog on | |

503 | ;; | |
d3ab8dac | 504 | ;; ps-print now knows rather precisely some fonts: |
bcc0d457 RS |
505 | ;; the variable `ps-font-info-database' contains information |
506 | ;; for a list of font families (currently mainly `Courier' `Helvetica' | |
507 | ;; `Times' `Palatino' `Helvetica-Narrow' `NewCenturySchlbk'). | |
508 | ;; Each font family contains the font names for standard, bold, italic | |
509 | ;; and bold-italic characters, a reference size (usually 10) and the | |
510 | ;; corresponding line height, width of a space and average character width. | |
06fb6aab | 511 | ;; |
bcc0d457 RS |
512 | ;; The variable `ps-font-family' determines which font family |
513 | ;; is to be used for ordinary text. | |
514 | ;; If its value does not correspond to a known font family, | |
515 | ;; an error message is printed into the `*Messages*' buffer, | |
516 | ;; which lists the currently available font families. | |
517 | ;; | |
518 | ;; The variable `ps-font-size' determines the size (in points) | |
915293a2 | 519 | ;; of the font for ordinary text, when generating PostScript. |
bcc0d457 RS |
520 | ;; Its value is a float. |

523 | ;; which font family is to be used for text in the header. | |
524 | ;; The variable `ps-header-font-size' determines the font size, | |
525 | ;; in points, for text in the header. | |

12b88fff | 530 | ;; Adding a New Font Family |
bcc0d457 RS |
531 | ;; ------------------------ |
532 | ;; | |
533 | ;; To use a new font family, you MUST first teach ps-print | |
87a16a06 | 534 | ;; this font, i.e., add its information to `ps-font-info-database', |
bcc0d457 RS |
535 | ;; otherwise ps-print cannot correctly place line and page breaks. |
536 | ;; | |
87a16a06 | 537 | ;; For example, assuming `Helvetica' is unknown, |
bcc0d457 RS |
538 | ;; you first need to do the following ONLY ONCE: |
539 | ;; | |
540 | ;; - create a new buffer | |
541 | ;; - generate the PostScript image to a file (C-u M-x ps-print-buffer) | |
542 | ;; - open this file and find the line: | |
543 | ;; `% 3 cm 20 cm moveto 10 /Courier ReportFontInfo showpage' | |
a18ed129 | 544 | ;; - delete the leading `%' (which is the PostScript comment character) |
bcc0d457 RS |
545 | ;; - replace in this line `Courier' by the new font (say `Helvetica') |
546 | ;; to get the line: | |
547 | ;; `3 cm 20 cm moveto 10 /Helvetica ReportFontInfo showpage' | |
548 | ;; - send this file to the printer (or to ghostscript). | |
549 | ;; You should read the following on the output page: | |
550 | ;; | |
551 | ;; For Helvetica 10 point, the line height is 11.56, the space width is 2.78 | |
552 | ;; and a crude estimate of average character width is 5.09243 | |
553 | ;; | |
554 | ;; - Add these values to the `ps-font-info-database': | |
555 | ;; (setq ps-font-info-database | |
12b88fff RS |
556 | ;; (append |
557 | ;; '((Helvetica ; the family key | |
558 | ;; (fonts (normal . "Helvetica") | |
559 | ;; (bold . "Helvetica-Bold") | |
560 | ;; (italic . "Helvetica-Oblique") | |
561 | ;; (bold-italic . "Helvetica-BoldOblique")) | |
562 | ;; (size . 10.0) | |
563 | ;; (line-height . 11.56) | |
564 | ;; (space-width . 2.78) | |
565 | ;; (avg-char-width . 5.09243))) | |
566 | ;; ps-font-info-database)) | |
bcc0d457 RS |
567 | ;; - Now you can use this font family with any size: |
568 | ;; (setq ps-font-family 'Helvetica) | |
569 | ;; - if you want to use this family in another emacs session, you must | |
570 | ;; put into your `~/.emacs': | |
571 | ;; (require 'ps-print) | |
572 | ;; (setq ps-font-info-database (append ...))) | |
573 | ;; if you don't want to load ps-print, you have to copy the whole value: | |
574 | ;; (setq ps-font-info-database '(<your stuff> <the standard stuff>)) | |
12b88fff RS |
575 | ;; or, use `ps-print-hook' (see section Hooks): |
576 | ;; (add-hook 'ps-print-hook | |
577 | ;; '(lambda () (setq ps-font-info-database (append ...)))) | |
bcc0d457 RS |
578 | ;; |
579 | ;; You can create new `mixed' font families like: | |
12b88fff RS |
580 | ;; (my-mixed-family |
581 | ;; (fonts (normal . "Courier-Bold") | |
582 | ;; (bold . "Helvetica") | |
583 | ;; (italic . "Zapf-Chancery-MediumItalic") | |
584 | ;; (bold-italic . "NewCenturySchlbk-BoldItalic") | |
585 | ;; (w3-table-hack-x-face . "LineDrawNormal")) | |
586 | ;; (size . 10.0) | |
587 | ;; (line-height . 10.55) | |
588 | ;; (space-width . 6.0) | |
589 | ;; (avg-char-width . 6.0)) | |
d3ab8dac | 590 | ;; |
bcc0d457 RS |
591 | ;; Now you can use your new font family with any size: |
592 | ;; (setq ps-font-family 'my-mixed-family) | |
593 | ;; | |
12b88fff RS |
594 | ;; Note that on above example the `w3-table-hack-x-face' entry refers to |
595 | ;; a face symbol, so when printing this face it'll be used the font | |
596 | ;; `LineDrawNormal'. If the face `w3-table-hack-x-face' is remapped to | |
597 | ;; use bold and/or italic attribute, the corresponding entry (bold, italic | |
598 | ;; or bold-italic) will be used instead of `w3-table-hack-x-face' entry. | |
599 | ;; | |
600 | ;; Note also that the font family entry order is irrelevant, so the above | |
601 | ;; example could also be written: | |
602 | ;; (my-mixed-family | |
603 | ;; (size . 10.0) | |
604 | ;; (fonts (w3-table-hack-x-face . "LineDrawNormal") | |
605 | ;; (bold . "Helvetica") | |
606 | ;; (bold-italic . "NewCenturySchlbk-BoldItalic") | |
607 | ;; (italic . "Zapf-Chancery-MediumItalic") | |
608 | ;; (normal . "Courier-Bold")) | |
609 | ;; (avg-char-width . 6.0) | |
610 | ;; (space-width . 6.0) | |
611 | ;; (line-height . 10.55)) | |
612 | ;; | |
613 | ;; Despite the note above, it is recommended that some convention about | |
614 | ;; entry order be used. | |
615 | ;; | |
bcc0d457 RS |
616 | ;; You can get information on all the fonts resident in YOUR printer |
617 | ;; by uncommenting the line: | |
618 | ;; % 3 cm 20 cm moveto ReportAllFontInfo showpage | |
619 | ;; | |
a18ed129 RS |
620 | ;; The PostScript file should be sent to YOUR PostScript printer. |
621 | ;; If you send it to ghostscript or to another PostScript printer, | |
bcc0d457 RS |
622 | ;; you may get slightly different results. |
623 | ;; Anyway, as ghostscript fonts are autoload, you won't get | |
624 | ;; much font info. | |

627 | ;; How Ps-Print Deals With Faces | |
628 | ;; ----------------------------- | |
12d89a2e | 629 | ;; |
bcc0d457 RS |
630 | ;; The ps-print-*-with-faces commands attempt to determine which faces |
631 | ;; should be printed in bold or italic, but their guesses aren't | |
632 | ;; always right. For example, you might want to map colors into faces | |
633 | ;; so that blue faces print in bold, and red faces in italic. | |
12d89a2e | 634 | ;; |
857686a6 RS |
635 | ;; It is possible to force ps-print to consider specific faces bold, |
636 | ;; italic or underline, no matter what font they are displayed in, by setting | |
637 | ;; the variables `ps-bold-faces', `ps-italic-faces' and `ps-underlined-faces'. | |
638 | ;; These variables contain lists of faces that ps-print should consider bold, | |
639 | ;; italic or underline; to set them, put code like the following into your | |
640 | ;; .emacs file: | |
12d89a2e | 641 | ;; |
12b88fff | 642 | ;; (setq ps-bold-faces '(my-blue-face)) |
bcc0d457 | 643 | ;; (setq ps-italic-faces '(my-red-face)) |
857686a6 | 644 | ;; (setq ps-underlined-faces '(my-green-face)) |
bcc0d457 RS |
645 | ;; |
646 | ;; Faces like bold-italic that are both bold and italic should go in | |
647 | ;; *both* lists. | |
648 | ;; | |
d3ab8dac | 649 | ;; ps-print keeps internal lists of which fonts are bold and which are |
bcc0d457 RS |
650 | ;; italic; these lists are built the first time you invoke ps-print. |
651 | ;; For the sake of efficiency, the lists are built only once; the same | |
652 | ;; lists are referred in later invocations of ps-print. | |
653 | ;; | |
654 | ;; Because these lists are built only once, it's possible for them to | |
655 | ;; get out of sync, if a face changes, or if new faces are added. To | |
656 | ;; get the lists back in sync, you can set the variable | |
657 | ;; `ps-build-face-reference' to t, and the lists will be rebuilt the | |
857686a6 RS |
658 | ;; next time ps-print is invoked. If you need that the lists always be |
659 | ;; rebuilt when ps-print is invoked, set the variable | |
660 | ;; `ps-always-build-face-reference' to t. | |
bcc0d457 RS |

663 | ;; How Ps-Print Deals With Color | |
664 | ;; ----------------------------- | |

bcc0d457 RS |
667 | ;; defined and embeds color information in the PostScript image. |
668 | ;; The default foreground and background colors are defined by the | |
669 | ;; variables `ps-default-fg' and `ps-default-bg'. | |
670 | ;; On black-and-white printers, colors are displayed in grayscale. | |
671 | ;; To turn off color output, set `ps-print-color-p' to nil. | |
672 | ;; | |
673 | ;; | |
87a16a06 RS |
674 | ;; How Ps-Print Maps Faces |
675 | ;; ----------------------- | |
676 | ;; | |
677 | ;; As ps-print uses PostScript to print buffers, it is possible to have | |
678 | ;; other attributes associated with faces. So the new attributes used | |
679 | ;; by ps-print are: | |
680 | ;; | |
681 | ;; strikeout - like underline, but the line is in middle of text. | |
682 | ;; overline - like underline, but the line is over the text. | |
683 | ;; shadow - text will have a shadow. | |
684 | ;; box - text will be surrounded by a box. | |
a18ed129 | 685 | ;; outline - print characters as hollow outlines. |
87a16a06 | 686 | ;; |
06fb6aab | 687 | ;; See the documentation for `ps-extend-face'. |
87a16a06 RS |
688 | ;; |
689 | ;; Let's, for example, remap font-lock-keyword-face to another foreground color | |
690 | ;; and bold attribute: | |
691 | ;; | |
a18ed129 | 692 | ;; (ps-extend-face '(font-lock-keyword-face "RoyalBlue" nil bold) 'MERGE) |
87a16a06 | 693 | ;; |
6c8f2753 RS |
694 | ;; If you want to use a new face, define it first with `defface', |
695 | ;; and then call `ps-extend-face' to specify how to print it. | |
696 | ;; | |
87a16a06 RS |
697 | ;; |
698 | ;; How Ps-Print Has A Text And/Or Image On Background | |
699 | ;; -------------------------------------------------- | |
700 | ;; | |
d3ab8dac | 701 | ;; ps-print can print texts and/or EPS PostScript images on background; it is |
87a16a06 RS |
702 | ;; possible to define the following text attributes: font name, font size, |
703 | ;; initial position, angle, gray scale and pages to print. | |
704 | ;; | |
705 | ;; It has the following EPS PostScript images attributes: file name containing | |
706 | ;; the image, initial position, X and Y scales, angle and pages to print. | |
707 | ;; | |
708 | ;; See documentation for `ps-print-background-text' and | |
709 | ;; `ps-print-background-image'. | |
710 | ;; | |
711 | ;; For example, if we wish to print text "preliminary" on all pages and text | |
712 | ;; "special" on page 5 and from page 11 to page 17, we could specify: | |
713 | ;; | |
714 | ;; (setq ps-print-background-text | |
715 | ;; '(("preliminary") | |
716 | ;; ("special" | |
717 | ;; "LeftMargin" "BottomMargin PrintHeight add" ; X and Y position | |

87a16a06 RS |
721 | ;; 5 (11 . 17)) ; page list |
722 | ;; )) | |
723 | ;; | |
724 | ;; Similarly, we could print image "~/images/EPS-image1.ps" on all pages and | |
725 | ;; image "~/images/EPS-image2.ps" on page 5 and from page 11 to page 17, we | |
726 | ;; specify: | |
727 | ;; | |
728 | ;; (setq ps-print-background-image | |
729 | ;; '(("~/images/EPS-image1.ps" | |
730 | ;; "LeftMargin" "BottomMargin") ; X and Y position (lower left corner) | |
731 | ;; ("~/images/EPS-image2.ps" | |
732 | ;; "LeftMargin" "BottomMargin PrintHeight 2 div add" ; X and Y position | |
733 | ;; ; (upper left corner) | |
734 | ;; nil nil nil | |

736 | ;; )) | |
737 | ;; | |
738 | ;; If it is not possible to read (or does not exist) an image file, that file | |
739 | ;; is ignored. | |
740 | ;; | |
741 | ;; The printing order is: | |

743 | ;; 1. Print zebra stripes | |
744 | ;; 2. Print background texts that it should be on all pages | |
