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

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

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

bcc0d457 RS |
239 | ;; If `ps-number-of-columns' is 1, `ps-inter-column' is not relevant. |

269 | ;; |
270 | ;; | |
271 | ;; Headers | |
bcc0d457 | 272 | ;; ------- |
12d89a2e | 273 | ;; |
12b88fff RS |
274 | ;; Ps-print can print headers at the top of each column or at the top |
275 | ;; of each page; the default headers contain the following four items: | |
276 | ;; on the left, the name of the buffer and, if the buffer is visiting | |
277 | ;; a file, the file's directory; on the right, the page number and | |
278 | ;; date of printing. The default headers look something like this: | |
12d89a2e RS |
279 | ;; |
280 | ;; ps-print.el 1/21 | |
281 | ;; /home/jct/emacs-lisp/ps/new 94/12/31 | |
06fb6aab | 282 | ;; |
12d89a2e | 283 | ;; When printing on duplex printers, left and right are reversed so |
bcc0d457 | 284 | ;; that the page numbers are toward the outside (cf. `ps-spool-duplex'). |
12d89a2e | 285 | ;; |
bcc0d457 RS |
286 | ;; Headers are configurable: |
287 | ;; To turn them off completely, set `ps-print-header' to nil. | |
288 | ;; To turn off the header's gaudy framing box, | |
289 | ;; set `ps-print-header-frame' to nil. | |
290 | ;; | |
12b88fff RS |
291 | ;; To print only one header at the top of each page, |
292 | ;; set `ps-print-only-one-header' to t. | |
293 | ;; | |
bcc0d457 | 294 | ;; The font family and size of text in the header are determined |
06fb6aab | 295 | ;; by the variables `ps-header-font-family', `ps-header-font-size' and |
bcc0d457 RS |
296 | ;; `ps-header-title-font-size' (see below). |
297 | ;; | |
298 | ;; The variable `ps-header-line-pad' determines the portion of a header | |
299 | ;; title line height to insert between the header frame and the text | |
300 | ;; it contains, both in the vertical and horizontal directions: | |
301 | ;; .5 means half a line. | |
302 | ||
303 | ;; Page numbers are printed in `n/m' format, indicating page n of m pages; | |
304 | ;; to omit the total page count and just print the page number, | |
305 | ;; set `ps-show-n-of-n' to nil. | |
12d89a2e RS |
306 | ;; |
307 | ;; The amount of information in the header can be changed by changing | |
bcc0d457 | 308 | ;; the number of lines. To show less, set `ps-header-lines' to 1, and |
12d89a2e | 309 | ;; the header will show only the buffer name and page number. To show |
bcc0d457 | 310 | ;; more, set `ps-header-lines' to 3, and the header will show the time of |
12d89a2e RS |
311 | ;; printing below the date. |
312 | ;; | |
313 | ;; To change the content of the headers, change the variables | |
bcc0d457 RS |
314 | ;; `ps-left-header' and `ps-right-header'. |
315 | ;; These variables are lists, specifying top-to-bottom the text | |
316 | ;; to display on the left or right side of the header. | |
317 | ;; Each element of the list should be a string or a symbol. | |
318 | ;; Strings are inserted directly into the PostScript arrays, | |
319 | ;; and should contain the PostScript string delimiters '(' and ')'. | |
12d89a2e RS |
320 | ;; |
321 | ;; Symbols in the header format lists can either represent functions | |
322 | ;; or variables. Functions are called, and should return a string to | |
323 | ;; show in the header. Variables should contain strings to display in | |
324 | ;; the header. In either case, function or variable, the PostScript | |
a7acbbe4 | 325 | ;; string delimiters are added by ps-print, and should not be part of |
12d89a2e RS |
326 | ;; the returned value. |
327 | ;; | |
328 | ;; Here's an example: say we want the left header to display the text | |
329 | ;; | |
330 | ;; Moe | |
331 | ;; Larry | |
332 | ;; Curly | |
333 | ;; | |
334 | ;; where we have a function to return "Moe" | |
335 | ;; | |
336 | ;; (defun moe-func () | |
337 | ;; "Moe") | |
338 | ;; | |
339 | ;; a variable specifying "Larry" | |
340 | ;; | |
341 | ;; (setq larry-var "Larry") | |
342 | ;; | |
bcc0d457 | 343 | ;; and a literal for "Curly". Here's how `ps-left-header' should be |
12d89a2e RS |
344 | ;; set: |
345 | ;; | |
346 | ;; (setq ps-left-header (list 'moe-func 'larry-var "(Curly)")) | |
347 | ;; | |
348 | ;; Note that Curly has the PostScript string delimiters inside his | |
bcc0d457 | 349 | ;; quotes -- those aren't misplaced lisp delimiters! |
87a16a06 | 350 | ;; |
bcc0d457 RS |
351 | ;; Without them, PostScript would attempt to call the undefined |
352 | ;; function Curly, which would result in a PostScript error. | |
87a16a06 | 353 | ;; |
bcc0d457 RS |
354 | ;; Since most printers don't report PostScript errors except by |
355 | ;; aborting the print job, this kind of error can be hard to track down. | |
87a16a06 | 356 | ;; |
bcc0d457 | 357 | ;; Consider yourself warned! |
12d89a2e RS |
358 | ;; |
359 | ;; | |
360 | ;; Duplex Printers | |
bcc0d457 | 361 | ;; --------------- |
12d89a2e RS |
362 | ;; |
363 | ;; If you have a duplex-capable printer (one that prints both sides of | |
bcc0d457 RS |
364 | ;; the paper), set `ps-spool-duplex' to t. |
365 | ;; Ps-print will insert blank pages to make sure each buffer starts | |
366 | ;; on the correct side of the paper. | |
367 | ;; Don't forget to set `ps-lpr-switches' to select duplex printing | |
368 | ;; for your printer. | |

857686a6 RS |
371 | ;; Control And 8-bit Characters |
372 | ;; ---------------------------- | |
373 | ;; | |
374 | ;; The variable `ps-print-control-characters' specifies whether you want to see | |
375 | ;; a printable form for control and 8-bit characters, that is, instead of | |
6bdb808e | 376 | ;; sending, for example, a ^D (\004) to printer, it is sent the string "^D". |
857686a6 RS |
377 | ;; |
378 | ;; Valid values for `ps-print-control-characters' are: | |
379 | ;; | |
c82b4a75 KH |
380 | ;; 8-bit This is the value to use when you want an ASCII encoding of |
381 | ;; any control or non-ASCII character. Control characters are | |
382 | ;; encoded as "^D", and non-ASCII characters have an | |
6bdb808e RS |

489 | ;; | |
490 | ;; Ps-print now knows rather precisely some fonts: | |
491 | ;; the variable `ps-font-info-database' contains information | |
492 | ;; for a list of font families (currently mainly `Courier' `Helvetica' | |
493 | ;; `Times' `Palatino' `Helvetica-Narrow' `NewCenturySchlbk'). | |
494 | ;; Each font family contains the font names for standard, bold, italic | |
495 | ;; and bold-italic characters, a reference size (usually 10) and the | |
496 | ;; corresponding line height, width of a space and average character width. | |
06fb6aab | 497 | ;; |
bcc0d457 RS |
498 | ;; The variable `ps-font-family' determines which font family |
499 | ;; is to be used for ordinary text. | |
500 | ;; If its value does not correspond to a known font family, | |
501 | ;; an error message is printed into the `*Messages*' buffer, | |
502 | ;; which lists the currently available font families. | |
503 | ;; | |
504 | ;; The variable `ps-font-size' determines the size (in points) | |
915293a2 | 505 | ;; of the font for ordinary text, when generating PostScript. |
bcc0d457 RS |
506 | ;; Its value is a float. |

12b88fff | 516 | ;; Adding a New Font Family |
bcc0d457 RS |
517 | ;; ------------------------ |
518 | ;; | |
519 | ;; To use a new font family, you MUST first teach ps-print | |
87a16a06 | 520 | ;; this font, i.e., add its information to `ps-font-info-database', |
bcc0d457 RS |
521 | ;; otherwise ps-print cannot correctly place line and page breaks. |
522 | ;; | |
87a16a06 | 523 | ;; For example, assuming `Helvetica' is unknown, |
bcc0d457 RS |
524 | ;; you first need to do the following ONLY ONCE: |
525 | ;; | |
526 | ;; - create a new buffer | |
527 | ;; - generate the PostScript image to a file (C-u M-x ps-print-buffer) | |
528 | ;; - open this file and find the line: | |
529 | ;; `% 3 cm 20 cm moveto 10 /Courier ReportFontInfo showpage' | |
a18ed129 | 530 | ;; - delete the leading `%' (which is the PostScript comment character) |
bcc0d457 RS |
531 | ;; - replace in this line `Courier' by the new font (say `Helvetica') |
532 | ;; to get the line: | |
533 | ;; `3 cm 20 cm moveto 10 /Helvetica ReportFontInfo showpage' | |
534 | ;; - send this file to the printer (or to ghostscript). | |
535 | ;; You should read the following on the output page: | |
536 | ;; | |
537 | ;; For Helvetica 10 point, the line height is 11.56, the space width is 2.78 | |
538 | ;; and a crude estimate of average character width is 5.09243 | |
539 | ;; | |
540 | ;; - Add these values to the `ps-font-info-database': | |
541 | ;; (setq ps-font-info-database | |
12b88fff RS |
542 | ;; (append |
543 | ;; '((Helvetica ; the family key | |
544 | ;; (fonts (normal . "Helvetica") | |
545 | ;; (bold . "Helvetica-Bold") | |
546 | ;; (italic . "Helvetica-Oblique") | |
547 | ;; (bold-italic . "Helvetica-BoldOblique")) | |
548 | ;; (size . 10.0) | |
549 | ;; (line-height . 11.56) | |
550 | ;; (space-width . 2.78) | |
551 | ;; (avg-char-width . 5.09243))) | |
552 | ;; ps-font-info-database)) | |
bcc0d457 RS |
553 | ;; - Now you can use this font family with any size: |
554 | ;; (setq ps-font-family 'Helvetica) | |
555 | ;; - if you want to use this family in another emacs session, you must | |
556 | ;; put into your `~/.emacs': | |
557 | ;; (require 'ps-print) | |
558 | ;; (setq ps-font-info-database (append ...))) | |
559 | ;; if you don't want to load ps-print, you have to copy the whole value: | |
560 | ;; (setq ps-font-info-database '(<your stuff> <the standard stuff>)) | |
12b88fff RS |
561 | ;; or, use `ps-print-hook' (see section Hooks): |
562 | ;; (add-hook 'ps-print-hook | |
563 | ;; '(lambda () (setq ps-font-info-database (append ...)))) | |
bcc0d457 RS |
564 | ;; |
565 | ;; You can create new `mixed' font families like: | |
12b88fff RS |
566 | ;; (my-mixed-family |
567 | ;; (fonts (normal . "Courier-Bold") | |
568 | ;; (bold . "Helvetica") | |
569 | ;; (italic . "Zapf-Chancery-MediumItalic") | |
570 | ;; (bold-italic . "NewCenturySchlbk-BoldItalic") | |
571 | ;; (w3-table-hack-x-face . "LineDrawNormal")) | |
572 | ;; (size . 10.0) | |
573 | ;; (line-height . 10.55) | |
574 | ;; (space-width . 6.0) | |
575 | ;; (avg-char-width . 6.0)) | |
bcc0d457 RS |
576 | ;; Now you can use your new font family with any size: |
577 | ;; (setq ps-font-family 'my-mixed-family) | |
578 | ;; | |
12b88fff RS |
579 | ;; Note that on above example the `w3-table-hack-x-face' entry refers to |
580 | ;; a face symbol, so when printing this face it'll be used the font | |
581 | ;; `LineDrawNormal'. If the face `w3-table-hack-x-face' is remapped to | |
582 | ;; use bold and/or italic attribute, the corresponding entry (bold, italic | |
583 | ;; or bold-italic) will be used instead of `w3-table-hack-x-face' entry. | |
584 | ;; | |
585 | ;; Note also that the font family entry order is irrelevant, so the above | |
586 | ;; example could also be written: | |
587 | ;; (my-mixed-family | |
588 | ;; (size . 10.0) | |
589 | ;; (fonts (w3-table-hack-x-face . "LineDrawNormal") | |
590 | ;; (bold . "Helvetica") | |
591 | ;; (bold-italic . "NewCenturySchlbk-BoldItalic") | |
592 | ;; (italic . "Zapf-Chancery-MediumItalic") | |
593 | ;; (normal . "Courier-Bold")) | |
594 | ;; (avg-char-width . 6.0) | |
595 | ;; (space-width . 6.0) | |
596 | ;; (line-height . 10.55)) | |
597 | ;; | |
598 | ;; Despite the note above, it is recommended that some convention about | |
599 | ;; entry order be used. | |
600 | ;; | |
bcc0d457 RS |
601 | ;; You can get information on all the fonts resident in YOUR printer |
602 | ;; by uncommenting the line: | |
603 | ;; % 3 cm 20 cm moveto ReportAllFontInfo showpage | |
604 | ;; | |
a18ed129 RS |
605 | ;; The PostScript file should be sent to YOUR PostScript printer. |
606 | ;; If you send it to ghostscript or to another PostScript printer, | |
bcc0d457 RS |
607 | ;; you may get slightly different results. |
608 | ;; Anyway, as ghostscript fonts are autoload, you won't get | |
609 | ;; much font info. | |

612 | ;; How Ps-Print Deals With Faces | |
613 | ;; ----------------------------- | |
12d89a2e | 614 | ;; |
bcc0d457 RS |
615 | ;; The ps-print-*-with-faces commands attempt to determine which faces |
616 | ;; should be printed in bold or italic, but their guesses aren't | |
617 | ;; always right. For example, you might want to map colors into faces | |
618 | ;; so that blue faces print in bold, and red faces in italic. | |
12d89a2e | 619 | ;; |
857686a6 RS |
620 | ;; It is possible to force ps-print to consider specific faces bold, |
621 | ;; italic or underline, no matter what font they are displayed in, by setting | |
622 | ;; the variables `ps-bold-faces', `ps-italic-faces' and `ps-underlined-faces'. | |
623 | ;; These variables contain lists of faces that ps-print should consider bold, | |
624 | ;; italic or underline; to set them, put code like the following into your | |
625 | ;; .emacs file: | |
12d89a2e | 626 | ;; |
12b88fff | 627 | ;; (setq ps-bold-faces '(my-blue-face)) |
bcc0d457 | 628 | ;; (setq ps-italic-faces '(my-red-face)) |
857686a6 | 629 | ;; (setq ps-underlined-faces '(my-green-face)) |
bcc0d457 RS |
630 | ;; |
631 | ;; Faces like bold-italic that are both bold and italic should go in | |
632 | ;; *both* lists. | |
633 | ;; | |
634 | ;; Ps-print keeps internal lists of which fonts are bold and which are | |
635 | ;; italic; these lists are built the first time you invoke ps-print. | |
636 | ;; For the sake of efficiency, the lists are built only once; the same | |
637 | ;; lists are referred in later invocations of ps-print. | |
638 | ;; | |
639 | ;; Because these lists are built only once, it's possible for them to | |
640 | ;; get out of sync, if a face changes, or if new faces are added. To | |
641 | ;; get the lists back in sync, you can set the variable | |
642 | ;; `ps-build-face-reference' to t, and the lists will be rebuilt the | |
857686a6 RS |
643 | ;; next time ps-print is invoked. If you need that the lists always be |
644 | ;; rebuilt when ps-print is invoked, set the variable | |
645 | ;; `ps-always-build-face-reference' to t. | |
bcc0d457 RS |
646 | ;; |
647 | ;; | |
648 | ;; How Ps-Print Deals With Color | |
649 | ;; ----------------------------- | |
650 | ;; | |
651 | ;; Ps-print detects faces with foreground and background colors | |
652 | ;; defined and embeds color information in the PostScript image. | |
653 | ;; The default foreground and background colors are defined by the | |
654 | ;; variables `ps-default-fg' and `ps-default-bg'. | |
655 | ;; On black-and-white printers, colors are displayed in grayscale. | |
656 | ;; To turn off color output, set `ps-print-color-p' to nil. | |
657 | ;; | |
658 | ;; | |
87a16a06 RS |
659 | ;; How Ps-Print Maps Faces |
660 | ;; ----------------------- | |
661 | ;; | |
662 | ;; As ps-print uses PostScript to print buffers, it is possible to have | |
663 | ;; other attributes associated with faces. So the new attributes used | |
664 | ;; by ps-print are: | |
665 | ;; | |
666 | ;; strikeout - like underline, but the line is in middle of text. | |
667 | ;; overline - like underline, but the line is over the text. | |
668 | ;; shadow - text will have a shadow. | |
669 | ;; box - text will be surrounded by a box. | |
a18ed129 | 670 | ;; outline - print characters as hollow outlines. |
87a16a06 | 671 | ;; |
06fb6aab | 672 | ;; See the documentation for `ps-extend-face'. |
87a16a06 RS |
673 | ;; |
674 | ;; Let's, for example, remap font-lock-keyword-face to another foreground color | |
675 | ;; and bold attribute: | |
676 | ;; | |
a18ed129 | 677 | ;; (ps-extend-face '(font-lock-keyword-face "RoyalBlue" nil bold) 'MERGE) |
87a16a06 | 678 | ;; |
6c8f2753 RS |
679 | ;; If you want to use a new face, define it first with `defface', |
680 | ;; and then call `ps-extend-face' to specify how to print it. | |
681 | ;; | |
87a16a06 RS |
682 | ;; |
683 | ;; How Ps-Print Has A Text And/Or Image On Background | |
684 | ;; -------------------------------------------------- | |
685 | ;; | |
686 | ;; Ps-print can print texts and/or EPS PostScript images on background; it is | |
687 | ;; possible to define the following text attributes: font name, font size, | |
688 | ;; initial position, angle, gray scale and pages to print. | |
689 | ;; | |
690 | ;; It has the following EPS PostScript images attributes: file name containing | |
691 | ;; the image, initial position, X and Y scales, angle and pages to print. | |
692 | ;; | |
693 | ;; See documentation for `ps-print-background-text' and | |
694 | ;; `ps-print-background-image'. | |
695 | ;; | |
696 | ;; For example, if we wish to print text "preliminary" on all pages and text | |
697 | ;; "special" on page 5 and from page 11 to page 17, we could specify: | |
698 | ;; | |
699 | ;; (setq ps-print-background-text | |
700 | ;; '(("preliminary") | |
701 | ;; ("special" | |
702 | ;; "LeftMargin" "BottomMargin PrintHeight add" ; X and Y position | |
703 | ;; ; (upper left corner) | |
704 | ;; nil nil nil | |
12b88fff | 705 | ;; "PrintHeight neg PrintPageWidth atan" ; angle |
87a16a06 RS |
706 | ;; 5 (11 . 17)) ; page list |
707 | ;; )) | |
708 | ;; | |
709 | ;; Similarly, we could print image "~/images/EPS-image1.ps" on all pages and | |
710 | ;; image "~/images/EPS-image2.ps" on page 5 and from page 11 to page 17, we | |
711 | ;; specify: | |
712 | ;; | |
713 | ;; (setq ps-print-background-image | |
714 | ;; '(("~/images/EPS-image1.ps" | |
715 | ;; "LeftMargin" "BottomMargin") ; X and Y position (lower left corner) | |
716 | ;; ("~/images/EPS-image2.ps" | |
717 | ;; "LeftMargin" "BottomMargin PrintHeight 2 div add" ; X and Y position | |
718 | ;; ; (upper left corner) | |
719 | ;; nil nil nil | |
720 | ;; 5 (11 . 17)) ; page list | |
721 | ;; )) | |
722 | ;; | |
723 | ;; If it is not possible to read (or does not exist) an image file, that file | |
724 | ;; is ignored. | |
725 | ;; | |
726 | ;; The printing order is: | |
727 | ;; | |
728 | ;; 1. Print zebra stripes | |
729 | ;; 2. Print background texts that it should be on all pages | |
730 | ;; 3. Print background images that it should be on all pages | |
731 | ;; 4. Print background texts only for current page (if any) | |
732 | ;; 5. Print background images only for current page (if any) | |
733 | ;; 6. Print header | |
a18ed129 | 734 | ;; 7. Print buffer text (with faces, if specified) and line number |

00aa16af | 819 | ;; with hilit19 and older versions of get-create-face. Users having |

1157 | The elements are: | |
1158 | ||
1159 | (STRING X Y FONT FONTSIZE GRAY ROTATION PAGES...) | |
1160 | ||
1161 | STRING is the text to be printed on background. | |
1162 | ||
1163 | X and Y are positions on paper to put the text. | |
1164 | If X and Y are nil, the text is positioned at lower left corner. | |
1165 | ||
1166 | FONT is a font name to be used on printing the text. | |
1167 | If nil, \"Times-Roman\" is used. | |
1168 | ||
1169 | FONTSIZE is font size to be used, if nil, 200 is used. | |
1170 | ||
1171 | GRAY is the text gray factor (should be very light like 0.8). | |
1172 | If nil, the default is 0.85. | |
1173 | ||
1174 | ROTATION is the text rotation angle; if nil, the angle is given by | |
1175 | the diagonal from lower left corner to upper right corner. | |
1176 | ||
1177 | PAGES designates the page to print background text. | |
1178 | PAGES may be a number or a cons cell (FROM . TO) designating FROM page | |
1179 | to TO page. | |
1180 | If PAGES is nil, print background text on all pages. | |
1181 | ||
1182 | X, Y, FONTSIZE, GRAY and ROTATION may be a floating point number, | |
1183 | an integer number or a string. If it is a string, the string should contain | |
1184 | PostScript programming that returns a float or integer value. | |

2835 | ||
2836 | FONT-TYPE is a type of font: normal, bold, italic, or bold-italic. | |
2837 | ||
2838 | FONT-SRC is a source of font: builtin, bdf, vflib, or nil. | |
2839 | ||
2840 | If FONT-SRC is builtin, FONT-NAME is a buitin PostScript font name. | |
2841 | ||
2842 | If FONT-SRC is bdf, FONT-NAME is a BDF font file name. To use this | |
2843 | font, the external library `bdf' is required. | |

2852 | ENCODING is a coding system to encode a string of characters of | |
2853 | CHARSET into a proper string matching an encoding of the specified | |
2854 | font. ENCODING may be a function to call to do this encoding. In | |
