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 | ;; | |
bc0d41bd | 184 | ;; The variable `ps-printer-name' determines the name of a local printer for |
d3ab8dac KH |
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 |
193 | ;; `printer-name'. | |
12d89a2e | 194 | ;; |
bc0d41bd KH |
195 | ;; The variable `ps-print-region-function' specifies a function to print the |
196 | ;; region on a PostScript printer. | |
197 | ;; See definition of `call-process-region' for calling conventions. The fourth | |
198 | ;; and the sixth arguments are both nil. | |

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

234 | ;; Horizontal layout |
235 | ;; ----------------- | |
12d89a2e | 236 | ;; |
bcc0d457 RS |
237 | ;; The horizontal layout is determined by the variables |

279 | ;; Headers | |
bcc0d457 | 280 | ;; ------- |
12d89a2e | 281 | ;; |
d3ab8dac | 282 | ;; ps-print can print headers at the top of each column or at the top |
12b88fff RS |
283 | ;; of each page; the default headers contain the following four items: |
284 | ;; on the left, the name of the buffer and, if the buffer is visiting | |
285 | ;; a file, the file's directory; on the right, the page number and | |
286 | ;; date of printing. The default headers look something like this: | |
12d89a2e RS |
287 | ;; |
288 | ;; ps-print.el 1/21 | |
289 | ;; /home/jct/emacs-lisp/ps/new 94/12/31 | |
06fb6aab | 290 | ;; |
12d89a2e | 291 | ;; When printing on duplex printers, left and right are reversed so |
bcc0d457 | 292 | ;; that the page numbers are toward the outside (cf. `ps-spool-duplex'). |
12d89a2e | 293 | ;; |
bcc0d457 RS |
294 | ;; Headers are configurable: |
295 | ;; To turn them off completely, set `ps-print-header' to nil. | |
296 | ;; To turn off the header's gaudy framing box, | |
297 | ;; set `ps-print-header-frame' to nil. | |
298 | ;; | |
12b88fff RS |
299 | ;; To print only one header at the top of each page, |
300 | ;; set `ps-print-only-one-header' to t. | |
301 | ;; | |
bcc0d457 | 302 | ;; The font family and size of text in the header are determined |
06fb6aab | 303 | ;; by the variables `ps-header-font-family', `ps-header-font-size' and |
bcc0d457 RS |
304 | ;; `ps-header-title-font-size' (see below). |
305 | ;; | |
306 | ;; The variable `ps-header-line-pad' determines the portion of a header | |
307 | ;; title line height to insert between the header frame and the text | |
308 | ;; it contains, both in the vertical and horizontal directions: | |
309 | ;; .5 means half a line. | |
310 | ||
311 | ;; Page numbers are printed in `n/m' format, indicating page n of m pages; | |
312 | ;; to omit the total page count and just print the page number, | |
313 | ;; set `ps-show-n-of-n' to nil. | |
12d89a2e RS |
314 | ;; |
315 | ;; The amount of information in the header can be changed by changing | |
bcc0d457 | 316 | ;; the number of lines. To show less, set `ps-header-lines' to 1, and |
12d89a2e | 317 | ;; the header will show only the buffer name and page number. To show |
bcc0d457 | 318 | ;; more, set `ps-header-lines' to 3, and the header will show the time of |
12d89a2e RS |
319 | ;; printing below the date. |
320 | ;; | |
321 | ;; To change the content of the headers, change the variables | |
bcc0d457 RS |
322 | ;; `ps-left-header' and `ps-right-header'. |
323 | ;; These variables are lists, specifying top-to-bottom the text | |
324 | ;; to display on the left or right side of the header. | |
325 | ;; Each element of the list should be a string or a symbol. | |
326 | ;; Strings are inserted directly into the PostScript arrays, | |
327 | ;; and should contain the PostScript string delimiters '(' and ')'. | |
12d89a2e RS |
328 | ;; |
329 | ;; Symbols in the header format lists can either represent functions | |
330 | ;; or variables. Functions are called, and should return a string to | |
331 | ;; show in the header. Variables should contain strings to display in | |
332 | ;; the header. In either case, function or variable, the PostScript | |
a7acbbe4 | 333 | ;; string delimiters are added by ps-print, and should not be part of |
12d89a2e RS |
334 | ;; the returned value. |
335 | ;; | |
336 | ;; Here's an example: say we want the left header to display the text | |
337 | ;; | |
338 | ;; Moe | |
339 | ;; Larry | |
340 | ;; Curly | |
341 | ;; | |
342 | ;; where we have a function to return "Moe" | |
343 | ;; | |
344 | ;; (defun moe-func () | |
345 | ;; "Moe") | |
346 | ;; | |
347 | ;; a variable specifying "Larry" | |
348 | ;; | |
349 | ;; (setq larry-var "Larry") | |
350 | ;; | |
bcc0d457 | 351 | ;; and a literal for "Curly". Here's how `ps-left-header' should be |
12d89a2e RS |
352 | ;; set: |
353 | ;; | |
354 | ;; (setq ps-left-header (list 'moe-func 'larry-var "(Curly)")) | |
355 | ;; | |
356 | ;; Note that Curly has the PostScript string delimiters inside his | |
bcc0d457 | 357 | ;; quotes -- those aren't misplaced lisp delimiters! |
87a16a06 | 358 | ;; |
bcc0d457 RS |
359 | ;; Without them, PostScript would attempt to call the undefined |
360 | ;; function Curly, which would result in a PostScript error. | |
87a16a06 | 361 | ;; |
bcc0d457 RS |
362 | ;; Since most printers don't report PostScript errors except by |
363 | ;; aborting the print job, this kind of error can be hard to track down. | |
87a16a06 | 364 | ;; |
bcc0d457 | 365 | ;; Consider yourself warned! |

369 | ;; -------------------------- | |
370 | ;; | |
371 | ;; It is possible to add PostScript prologue header comments besides that | |

373 | ;; | |
bc0d41bd KH |

402 | ;; If you have a duplex-capable printer (one that prints both sides of the |
403 | ;; paper), set `ps-spool-duplex' to t. | |
404 | ;; ps-print will insert blank pages to make sure each buffer starts on the | |
405 | ;; correct side of the paper. | |
406 | ;; | |
407 | ;; The variable `ps-spool-config' specifies who is the responsable for setting | |
408 | ;; duplex and page size switches. Valid values are: | |
409 | ;; | |
410 | ;; lpr-switches duplex and page size are configured by `ps-lpr-switches'. | |
411 | ;; Don't forget to set `ps-lpr-switches' to select duplex | |
412 | ;; printing for your printer. | |
413 | ;; | |
414 | ;; setpagedevice duplex and page size are configured by ps-print using the | |
415 | ;; setpagedevice PostScript operator. | |
416 | ;; | |
417 | ;; nil duplex and page size are configured by ps-print *not* using | |
418 | ;; the setpagedevice PostScript operator. | |
419 | ;; | |
420 | ;; Any other value is treated as nil. | |
421 | ;; | |
422 | ;; The default value is `lpr-switches'. | |
423 | ;; | |
424 | ;; WARNING: The setpagedevice PostScript operator affects ghostview utility when | |
425 | ;; viewing file generated using landscape. Also on some printers, | |
426 | ;; setpagedevice affects zebra stripes; on other printers, | |
427 | ;; setpagedevice affects the left margin. | |
428 | ;; Besides all that, if your printer does not have the paper size | |
429 | ;; specified by setpagedevice, your printing will be aborted. | |
430 | ;; So, if you need to use setpagedevice, set `ps-spool-config' to | |
431 | ;; `setpagedevice', generate a test file and send it to your printer; | |
432 | ;; if the printed file isn't ok, set `ps-spool-config' to nil. | |
433 | ;; | |
434 | ;; The variable `ps-spool-tumble' specifies how the page images on opposite | |
435 | ;; sides of a sheet are oriented with respect to each other. If | |
436 | ;; `ps-spool-tumble' is nil, produces output suitable for binding on the left or | |
437 | ;; right. If `ps-spool-tumble' is non-nil, produces output suitable for binding | |
438 | ;; at the top or bottom. It has effect only when `ps-spool-duplex' is non-nil. | |
439 | ;; The default value is nil. | |
440 | ;; | |
441 | ;; Some printer system prints a header page and forces the first page be printed | |
442 | ;; on header page back, when using duplex. If your printer system has this | |
443 | ;; behavior, set variable `ps-banner-page-when-duplexing' to t. | |
444 | ;; | |
445 | ;; When `ps-banner-page-when-duplexing' is non-nil means the very first page is | |
446 | ;; skipped. It's like the very first character of buffer (or region) is ^L | |
447 | ;; (\014). | |
448 | ;; | |
449 | ;; The default for `ps-banner-page-when-duplexing' is nil (*don't* skip the very | |
450 | ;; first page). | |
451 | ;; | |
452 | ;; | |
453 | ;; N-up Printing | |
454 | ;; ------------- | |
455 | ;; | |
456 | ;; The variable `ps-n-up-printing' specifies the number of pages per sheet of | |
457 | ;; paper. The value specified must be between 1 and 100. The default is 1. | |
458 | ;; | |
459 | ;; NOTE: some PostScript printer may crash printing if `ps-n-up-printing' is set | |
460 | ;; to a high value (for example, 23). If this happens, set a lower value. | |
461 | ;; | |
462 | ;; The variable `ps-n-up-margin' specifies the margin in points between the | |
463 | ;; sheet border and the n-up printing. The default is 1 cm (or 0.3937 inches, | |
464 | ;; or 28.35 points). | |
465 | ;; | |
466 | ;; If variable `ps-n-up-border-p' is non-nil a border is drawn around each page. | |
467 | ;; The default is t. | |
468 | ;; | |
469 | ;; The variable `ps-n-up-filling' specifies how page matrix is filled on each | |
470 | ;; sheet of paper. Following are the valid values for `ps-n-up-filling' with a | |
471 | ;; filling example using a 3x4 page matrix: | |
472 | ;; | |
473 | ;; left-top 1 2 3 4 left-bottom 9 10 11 12 | |

487 | ;; 12 9 6 3 10 7 4 1 | |
488 | ;; | |
489 | ;; Any other value is treated as left-top. | |
490 | ;; | |

498 | ;; a printable form for control and 8-bit characters, that is, instead of | |
6bdb808e | 499 | ;; sending, for example, a ^D (\004) to printer, it is sent the string "^D". |
857686a6 RS |

603 | ;; ps-print now knows rather precisely some fonts: the variable |
604 | ;; `ps-font-info-database' contains information for a list of font families | |
605 | ;; (currently mainly `Courier' `Helvetica' `Times' `Palatino' `Helvetica-Narrow' | |
606 | ;; `NewCenturySchlbk'). Each font family contains the font names for standard, | |
607 | ;; bold, italic and bold-italic characters, a reference size (usually 10) and | |
608 | ;; the corresponding line height, width of a space and average character width. | |
06fb6aab | 609 | ;; |
7d8b7e8e KH |
610 | ;; The variable `ps-font-family' determines which font family is to be used for |
611 | ;; ordinary text. If its value does not correspond to a known font family, an | |
612 | ;; error message is printed into the `*Messages*' buffer, which lists the | |
613 | ;; currently available font families. | |
bcc0d457 | 614 | ;; |
7d8b7e8e KH |
615 | ;; The variable `ps-font-size' determines the size (in points) of the font for |
616 | ;; ordinary text, when generating PostScript. Its value is a float or a cons of | |

12b88fff | 631 | ;; Adding a New Font Family |
bcc0d457 RS |
632 | ;; ------------------------ |
633 | ;; | |
634 | ;; To use a new font family, you MUST first teach ps-print | |
87a16a06 | 635 | ;; this font, i.e., add its information to `ps-font-info-database', |
bcc0d457 RS |
636 | ;; otherwise ps-print cannot correctly place line and page breaks. |
637 | ;; | |
87a16a06 | 638 | ;; For example, assuming `Helvetica' is unknown, |
bcc0d457 RS |
639 | ;; you first need to do the following ONLY ONCE: |
640 | ;; | |
641 | ;; - create a new buffer | |
642 | ;; - generate the PostScript image to a file (C-u M-x ps-print-buffer) | |
643 | ;; - open this file and find the line: | |
644 | ;; `% 3 cm 20 cm moveto 10 /Courier ReportFontInfo showpage' | |
a18ed129 | 645 | ;; - delete the leading `%' (which is the PostScript comment character) |
bcc0d457 RS |
646 | ;; - replace in this line `Courier' by the new font (say `Helvetica') |
647 | ;; to get the line: | |
648 | ;; `3 cm 20 cm moveto 10 /Helvetica ReportFontInfo showpage' | |
649 | ;; - send this file to the printer (or to ghostscript). | |
650 | ;; You should read the following on the output page: | |
651 | ;; | |
652 | ;; For Helvetica 10 point, the line height is 11.56, the space width is 2.78 | |
653 | ;; and a crude estimate of average character width is 5.09243 | |
654 | ;; | |
655 | ;; - Add these values to the `ps-font-info-database': | |
656 | ;; (setq ps-font-info-database | |
12b88fff RS |
657 | ;; (append |
658 | ;; '((Helvetica ; the family key | |
659 | ;; (fonts (normal . "Helvetica") | |
660 | ;; (bold . "Helvetica-Bold") | |
661 | ;; (italic . "Helvetica-Oblique") | |

664 | ;; (line-height . 11.56) | |
665 | ;; (space-width . 2.78) | |
666 | ;; (avg-char-width . 5.09243))) | |
667 | ;; ps-font-info-database)) | |
bcc0d457 RS |
668 | ;; - Now you can use this font family with any size: |
669 | ;; (setq ps-font-family 'Helvetica) | |
670 | ;; - if you want to use this family in another emacs session, you must | |
671 | ;; put into your `~/.emacs': | |
672 | ;; (require 'ps-print) | |
673 | ;; (setq ps-font-info-database (append ...))) | |
674 | ;; if you don't want to load ps-print, you have to copy the whole value: | |
675 | ;; (setq ps-font-info-database '(<your stuff> <the standard stuff>)) | |
12b88fff RS |
676 | ;; or, use `ps-print-hook' (see section Hooks): |
677 | ;; (add-hook 'ps-print-hook | |
bc0d41bd KH |
678 | ;; '(lambda () |
679 | ;; (or (assq 'Helvetica ps-font-info-database) | |
680 | ;; (setq ps-font-info-database (append ...))))) | |

bcc0d457 RS |
694 | ;; Now you can use your new font family with any size: |
695 | ;; (setq ps-font-family 'my-mixed-family) | |
696 | ;; | |
12b88fff RS |
697 | ;; Note that on above example the `w3-table-hack-x-face' entry refers to |
698 | ;; a face symbol, so when printing this face it'll be used the font | |
699 | ;; `LineDrawNormal'. If the face `w3-table-hack-x-face' is remapped to | |
700 | ;; use bold and/or italic attribute, the corresponding entry (bold, italic | |
701 | ;; or bold-italic) will be used instead of `w3-table-hack-x-face' entry. | |
702 | ;; | |
703 | ;; Note also that the font family entry order is irrelevant, so the above | |
704 | ;; example could also be written: | |
705 | ;; (my-mixed-family | |
706 | ;; (size . 10.0) | |
707 | ;; (fonts (w3-table-hack-x-face . "LineDrawNormal") | |
708 | ;; (bold . "Helvetica") | |
709 | ;; (bold-italic . "NewCenturySchlbk-BoldItalic") | |

711 | ;; (normal . "Courier-Bold")) | |
712 | ;; (avg-char-width . 6.0) | |
713 | ;; (space-width . 6.0) | |
714 | ;; (line-height . 10.55)) | |
715 | ;; | |
716 | ;; Despite the note above, it is recommended that some convention about | |
717 | ;; entry order be used. | |
718 | ;; | |
bcc0d457 RS |
719 | ;; You can get information on all the fonts resident in YOUR printer |
720 | ;; by uncommenting the line: | |

722 | ;; | |
a18ed129 RS |
723 | ;; The PostScript file should be sent to YOUR PostScript printer. |

bcc0d457 RS |

730 | ;; How Ps-Print Deals With Faces | |
731 | ;; ----------------------------- | |
12d89a2e | 732 | ;; |
bcc0d457 RS |
733 | ;; The ps-print-*-with-faces commands attempt to determine which faces |
734 | ;; should be printed in bold or italic, but their guesses aren't | |
735 | ;; always right. For example, you might want to map colors into faces | |
736 | ;; so that blue faces print in bold, and red faces in italic. | |
12d89a2e | 737 | ;; |
857686a6 RS |
738 | ;; It is possible to force ps-print to consider specific faces bold, |
739 | ;; italic or underline, no matter what font they are displayed in, by setting | |
740 | ;; the variables `ps-bold-faces', `ps-italic-faces' and `ps-underlined-faces'. | |
741 | ;; These variables contain lists of faces that ps-print should consider bold, | |
742 | ;; italic or underline; to set them, put code like the following into your | |
743 | ;; .emacs file: | |
12d89a2e | 744 | ;; |
12b88fff | 745 | ;; (setq ps-bold-faces '(my-blue-face)) |
bcc0d457 | 746 | ;; (setq ps-italic-faces '(my-red-face)) |
857686a6 | 747 | ;; (setq ps-underlined-faces '(my-green-face)) |
bcc0d457 RS |
748 | ;; |
749 | ;; Faces like bold-italic that are both bold and italic should go in | |
750 | ;; *both* lists. | |
751 | ;; | |
d3ab8dac | 752 | ;; ps-print keeps internal lists of which fonts are bold and which are |

754 | ;; For the sake of efficiency, the lists are built only once; the same | |
755 | ;; lists are referred in later invocations of ps-print. | |
756 | ;; | |
757 | ;; Because these lists are built only once, it's possible for them to | |
758 | ;; get out of sync, if a face changes, or if new faces are added. To | |
759 | ;; get the lists back in sync, you can set the variable | |
760 | ;; `ps-build-face-reference' to t, and the lists will be rebuilt the | |
857686a6 RS |
761 | ;; next time ps-print is invoked. If you need that the lists always be |
762 | ;; rebuilt when ps-print is invoked, set the variable | |
763 | ;; `ps-always-build-face-reference' to t. | |

766 | ;; How Ps-Print Deals With Color | |
767 | ;; ----------------------------- | |
768 | ;; | |
d3ab8dac | 769 | ;; ps-print detects faces with foreground and background colors |
bcc0d457 RS |
770 | ;; defined and embeds color information in the PostScript image. |
771 | ;; The default foreground and background colors are defined by the | |
772 | ;; variables `ps-default-fg' and `ps-default-bg'. | |
773 | ;; On black-and-white printers, colors are displayed in grayscale. | |
774 | ;; To turn off color output, set `ps-print-color-p' to nil. | |
775 | ;; | |
776 | ;; | |
87a16a06 RS |
777 | ;; How Ps-Print Maps Faces |
778 | ;; ----------------------- | |
779 | ;; | |
780 | ;; As ps-print uses PostScript to print buffers, it is possible to have | |
781 | ;; other attributes associated with faces. So the new attributes used | |
782 | ;; by ps-print are: | |
783 | ;; | |
784 | ;; strikeout - like underline, but the line is in middle of text. | |
785 | ;; overline - like underline, but the line is over the text. | |
786 | ;; shadow - text will have a shadow. | |
787 | ;; box - text will be surrounded by a box. | |
a18ed129 | 788 | ;; outline - print characters as hollow outlines. |
87a16a06 | 789 | ;; |
06fb6aab | 790 | ;; See the documentation for `ps-extend-face'. |
87a16a06 | 791 | ;; |
bc0d41bd KH |
792 | ;; Let's, for example, remap `font-lock-keyword-face' to another foreground |
793 | ;; color and bold attribute: | |
87a16a06 | 794 | ;; |
a18ed129 | 795 | ;; (ps-extend-face '(font-lock-keyword-face "RoyalBlue" nil bold) 'MERGE) |
87a16a06 | 796 | ;; |
6c8f2753 RS |
797 | ;; If you want to use a new face, define it first with `defface', |
798 | ;; and then call `ps-extend-face' to specify how to print it. | |
799 | ;; | |

800 | ;; |
801 | ;; How Ps-Print Has A Text And/Or Image On Background | |
802 | ;; -------------------------------------------------- | |
803 | ;; | |
d3ab8dac | 804 | ;; ps-print can print texts and/or EPS PostScript images on background; it is |
87a16a06 RS |
805 | ;; possible to define the following text attributes: font name, font size, |
806 | ;; initial position, angle, gray scale and pages to print. | |
807 | ;; | |
808 | ;; It has the following EPS PostScript images attributes: file name containing | |
809 | ;; the image, initial position, X and Y scales, angle and pages to print. | |
810 | ;; | |
811 | ;; See documentation for `ps-print-background-text' and | |
812 | ;; `ps-print-background-image'. | |
813 | ;; | |
814 | ;; For example, if we wish to print text "preliminary" on all pages and text | |
815 | ;; "special" on page 5 and from page 11 to page 17, we could specify: | |
816 | ;; | |
817 | ;; (setq ps-print-background-text | |
818 | ;; '(("preliminary") | |
819 | ;; ("special" | |
820 | ;; "LeftMargin" "BottomMargin PrintHeight add" ; X and Y position | |
821 | ;; ; (upper left corner) | |
822 | ;; nil nil nil | |
12b88fff | 823 | ;; "PrintHeight neg PrintPageWidth atan" ; angle |
87a16a06 RS |
824 | ;; 5 (11 . 17)) ; page list |
825 | ;; )) | |
826 | ;; | |
827 | ;; Similarly, we could print image "~/images/EPS-image1.ps" on all pages and | |
828 | ;; image "~/images/EPS-image2.ps" on page 5 and from page 11 to page 17, we | |
829 | ;; specify: | |
830 | ;; | |
831 | ;; (setq ps-print-background-image | |
832 | ;; '(("~/images/EPS-image1.ps" | |
833 | ;; "LeftMargin" "BottomMargin") ; X and Y position (lower left corner) | |
834 | ;; ("~/images/EPS-image2.ps" | |
835 | ;; "LeftMargin" "BottomMargin PrintHeight 2 div add" ; X and Y position | |
836 | ;; ; (upper left corner) | |
837 | ;; nil nil nil | |
838 | ;; 5 (11 . 17)) ; page list | |
839 | ;; )) | |
840 | ;; | |
841 | ;; If it is not possible to read (or does not exist) an image file, that file | |
842 | ;; is ignored. | |
843 | ;; | |
844 | ;; The printing order is: | |
845 | ;; | |
846 | ;; 1. Print zebra stripes | |
847 | ;; 2. Print background texts that it should be on all pages | |
848 | ;; 3. Print background images that it should be on all pages | |
849 | ;; 4. Print background texts only for current page (if any) | |
850 | ;; 5. Print background images only for current page (if any) | |
851 | ;; 6. Print header | |
a18ed129 | 852 | ;; 7. Print buffer text (with faces, if specified) and line number |

855 | ;; Utilities |
856 | ;; --------- | |
857 | ;; | |
858 | ;; Some tools are provided to help you customize your font setup. | |
859 | ;; | |
860 | ;; `ps-setup' returns (some part of) the current setup. | |
861 | ;; | |
862 | ;; To avoid wrapping too many lines, you may want to adjust the | |
863 | ;; left and right margins and the font size. On UN*X systems, do: | |
864 | ;; pr -t file | awk '{printf "%3d %s\n", length($0), $0}' | sort -r | head | |
865 | ;; to determine the longest lines of your file. | |
87a16a06 | 866 | ;; Then, the command `ps-line-lengths' will give you the correspondence |
bcc0d457 RS |
867 | ;; between a line length (number of characters) and the maximum font |
868 | ;; size which doesn't wrap such a line with the current ps-print setup. | |
869 | ;; | |
870 | ;; The commands `ps-nb-pages-buffer' and `ps-nb-pages-region' display | |
87a16a06 | 871 | ;; the correspondence between a number of pages and the maximum font |
bcc0d457 RS |
872 | ;; size which allow the number of lines of the current buffer or of |
873 | ;; its current region to fit in this number of pages. | |
