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
54 ;; Emacs 19 or Lucid Emacs, together with a fontifying package such as
55 ;; font-lock or hilit.
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.
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).
70 ;; ps-print provides eight commands for generating PostScript images
74 ;; ps-print-buffer-with-faces
76 ;; ps-print-region-with-faces
78 ;; ps-spool-buffer-with-faces
80 ;; ps-spool-region-with-faces
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".
87 ;; The word "print" or "spool" in the command name determines when the
88 ;; PostScript image is sent to the printer:
90 ;; print - The PostScript image is immediately sent to the
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
96 ;; to the printer, use the command `ps-despool'.
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).
104 ;; ps-print has a hook in the `kill-emacs-hook' so that you won't
105 ;; accidentally quit from Emacs while you have unprinted PostScript
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.
111 ;; The word "buffer" or "region" in the command name determines how
112 ;; much of the buffer is printed:
114 ;; buffer - Print the entire buffer.
116 ;; region - Print just the current region.
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.
125 ;; Two ps-print- command examples:
127 ;; ps-print-buffer - print the entire buffer,
128 ;; without font, color, or
129 ;; underline information, and
130 ;; send it immediately to the
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.
143 ;; To print your buffer, type
145 ;; M-x ps-print-buffer
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
151 ;; C-u M-x ps-print-buffer
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
157 ;; file by giving a prefix argument to `ps-despool':
159 ;; C-u M-x ps-despool
161 ;; When invoked this way, `ps-despool' will prompt you for the name of
162 ;; the file to save to.
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:
168 ;; (global-set-key 'f22 'ps-spool-buffer-with-faces) ;f22 is prsc
169 ;; (global-set-key '(shift f22) 'ps-spool-region-with-faces)
170 ;; (global-set-key '(control f22) 'ps-despool)
173 ;; The Printer Interface
174 ;; ---------------------
176 ;; The variables `ps-lpr-command' and `ps-lpr-switches' determine what
177 ;; command is used to send the PostScript images to the printer, and
178 ;; what arguments to give the command. These are analogous to
179 ;; `lpr-command' and `lpr-switches'.
181 ;; Make sure that they contain appropriate values for your system;
182 ;; see the usage notes below and the documentation of these variables.
184 ;; The variable `ps-printer-name' determines the name of a local printer for
185 ;; printing PostScript files.
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
191 ;; a program that does not format the files it prints.
192 ;; `ps-printer-name' takes its initial value from the variable
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.
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
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'
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.
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.
224 ;; The variable `ps-number-of-columns' determines the number of columns
225 ;; both in landscape and portrait mode.
227 ;; - (the standard) one column portrait mode
228 ;; - (my favorite) two columns landscape mode (which spares trees)
230 ;; - one column landscape mode for files with very long lines.
231 ;; - multi-column portrait or landscape mode
237 ;; The horizontal layout is determined by the variables
238 ;; `ps-left-margin' `ps-inter-column' `ps-right-margin'
241 ;; ------------------------------------------
243 ;; | lm | text | ic | text | ic | text | rm |
245 ;; ------------------------------------------
247 ;; If `ps-number-of-columns' is 1, `ps-inter-column' is not relevant.
248 ;; Usually, lm = rm > 0 and ic = lm
249 ;; If (ic < 0), the text of adjacent columns can overlap.
255 ;; The vertical layout is determined by the variables
256 ;; `ps-bottom-margin' `ps-top-margin' `ps-header-offset'
259 ;; |--------| |--------|
261 ;; |--------| |--------|
265 ;; |--------| or | text |
269 ;; |--------| |--------|
271 ;; |--------| |--------|
273 ;; If `ps-print-header' is nil, `ps-header-offset' is not relevant.
274 ;; The margins represent margins in the printed paper:
275 ;; the top margin is the margin between the top of the page
276 ;; and the printed header, whatever the orientation is.
282 ;; ps-print can print headers at the top of each column or at the top
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:
289 ;; /home/jct/emacs-lisp/ps/new 94/12/31
291 ;; When printing on duplex printers, left and right are reversed so
292 ;; that the page numbers are toward the outside (cf. `ps-spool-duplex').
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.
299 ;; To print only one header at the top of each page,
300 ;; set `ps-print-only-one-header' to t.
302 ;; The font family and size of text in the header are determined
303 ;; by the variables `ps-header-font-family', `ps-header-font-size' and
304 ;; `ps-header-title-font-size' (see below).
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.
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.
315 ;; The amount of information in the header can be changed by changing
316 ;; the number of lines. To show less, set `ps-header-lines' to 1, and
317 ;; the header will show only the buffer name and page number. To show
318 ;; more, set `ps-header-lines' to 3, and the header will show the time of
319 ;; printing below the date.
321 ;; To change the content of the headers, change the variables
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 ')'.
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
333 ;; string delimiters are added by ps-print, and should not be part of
334 ;; the returned value.
336 ;; Here's an example: say we want the left header to display the text
342 ;; where we have a function to return "Moe"
344 ;; (defun moe-func ()
347 ;; a variable specifying "Larry"
349 ;; (setq larry-var "Larry")
351 ;; and a literal for "Curly". Here's how `ps-left-header' should be
354 ;; (setq ps-left-header (list 'moe-func 'larry-var "(Curly)"))
356 ;; Note that Curly has the PostScript string delimiters inside his
357 ;; quotes -- those aren't misplaced lisp delimiters!
359 ;; Without them, PostScript would attempt to call the undefined
360 ;; function Curly, which would result in a PostScript error.
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.
365 ;; Consider yourself warned!
368 ;; PostScript Prologue Header
369 ;; --------------------------
371 ;; It is possible to add PostScript prologue header comments besides that
372 ;; ps-print generates by setting the variable `ps-print-prologue-header'.
374 ;; `ps-print-prologue-header' may be a string or a symbol function which returns
375 ;; a string. Note that this string is inserted on PostScript prologue header
376 ;; section which is used to define some document characteristic through
377 ;; PostScript special comments, like "%%Requirements: jog\n".
379 ;; By default `ps-print-prologue-header' is nil.
381 ;; ps-print always inserts the %%Requirements: comment, so if you need to insert
382 ;; more requirements put them first in `ps-print-prologue-header' using the
383 ;; "%%+" comment. For example, if you need to set numcopies to 3 and jog on
384 ;; requirements and set %%LanguageLevel: to 2, do:
386 ;; (setq ps-print-prologue-header
387 ;; "%%+ numcopies(3) jog\n%%LanguageLevel: 2\n")
389 ;; The duplex requirement is inserted by ps-print (see section Duplex Printers).
391 ;; Do not forget to terminate the string with "\n".
393 ;; For more information about PostScript document comments, see:
394 ;; PostScript Language Reference Manual (2nd edition)
395 ;; Adobe Systems Incorporated
396 ;; Appendix G: Document Structuring Conventions -- Version 3.0
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.
407 ;; The variable `ps-spool-config' specifies who is the responsable for setting
408 ;; duplex and page size switches. Valid values are:
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.
414 ;; setpagedevice duplex and page size are configured by ps-print using the
415 ;; setpagedevice PostScript operator.
417 ;; nil duplex and page size are configured by ps-print *not* using
418 ;; the setpagedevice PostScript operator.
420 ;; Any other value is treated as nil.
422 ;; The default value is `lpr-switches'.
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.
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.
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.
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
449 ;; The default for `ps-banner-page-when-duplexing' is nil (*don't* skip the very
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.
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.
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,
466 ;; If variable `ps-n-up-border-p' is non-nil a border is drawn around each page.
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:
473 ;; left-top 1 2 3 4 left-bottom 9 10 11 12
475 ;; 9 10 11 12 1 2 3 4
477 ;; right-top 4 3 2 1 right-bottom 12 11 10 9
479 ;; 12 11 10 9 4 3 2 1
481 ;; top-left 1 4 7 10 bottom-left 3 6 9 12
485 ;; top-right 10 7 4 1 bottom-right 12 9 6 3
489 ;; Any other value is treated as left-top.
491 ;; The default value is left-top.
494 ;; Control And 8-bit Characters
495 ;; ----------------------------
497 ;; The variable `ps-print-control-characters' specifies whether you want to see
498 ;; a printable form for control and 8-bit characters, that is, instead of
499 ;; sending, for example, a ^D (\004) to printer, it is sent the string "^D".
501 ;; Valid values for `ps-print-control-characters' are:
503 ;; 8-bit This is the value to use when you want an ASCII encoding of
504 ;; any control or non-ASCII character. Control characters are
505 ;; encoded as "^D", and non-ASCII characters have an
508 ;; control-8-bit This is the value to use when you want an ASCII encoding of
509 ;; any control character, whether it is 7 or 8-bit.
510 ;; European 8-bits accented characters are printed according
513 ;; control Only ASCII control characters have an ASCII encoding.
514 ;; European 8-bits accented characters are printed according
517 ;; nil No ASCII encoding. Any character is printed according the
520 ;; Any other value is treated as nil.
522 ;; The default is `control-8-bit'.
524 ;; Characters TAB, NEWLINE and FORMFEED are always treated by ps-print engine.
527 ;; Printing Multi-byte Buffer
528 ;; --------------------------
530 ;; See ps-mule.el for documentation.
532 ;; See ps-print-def.el for definition.
538 ;; The variable `ps-line-number' specifies whether to number each line;
539 ;; non-nil means do so. The default is nil (don't number each line).
545 ;; Zebra stripes are a kind of background that appear "underneath" the text
546 ;; and can make the text easier to read. They look like this:
548 ;; XXXXXXXXXXXXXXXXXXXXXXXX
549 ;; XXXXXXXXXXXXXXXXXXXXXXXX
550 ;; XXXXXXXXXXXXXXXXXXXXXXXX
554 ;; XXXXXXXXXXXXXXXXXXXXXXXX
555 ;; XXXXXXXXXXXXXXXXXXXXXXXX
556 ;; XXXXXXXXXXXXXXXXXXXXXXXX
558 ;; The blocks of X's represent rectangles filled with a light gray color.
559 ;; Each rectangle extends all the way across the page.
561 ;; The height, in lines, of each rectangle is controlled by
562 ;; the variable `ps-zebra-stripe-height', which is 3 by default.
563 ;; The distance between stripes equals the height of a stripe.
565 ;; The variable `ps-zebra-stripes' controls whether to print zebra stripes.
566 ;; Non-nil means yes, nil means no. The default is nil.
568 ;; The variable `ps-zebra-gray' controls the zebra stripes gray scale.
569 ;; It should be a float number between 0.0 (black color) and 1.0 (white color).
570 ;; The default is 0.95.
572 ;; See also section How Ps-Print Has A Text And/Or Image On Background.
578 ;; ps-print has the following hook variables:
581 ;; It is evaluated once before any printing process. This is the right
582 ;; place to initialize ps-print global data.
583 ;; For an example, see section Adding a New Font Family.
585 ;; `ps-print-begin-sheet-hook'
586 ;; It is evaluated on each beginning of sheet of paper.
587 ;; If `ps-n-up-printing' is equal to 1, `ps-print-begin-page-hook' is never
590 ;; `ps-print-begin-page-hook'
591 ;; It is evaluated on each beginning of page, except in the beginning
592 ;; of page that `ps-print-begin-sheet-hook' is evaluated.
594 ;; `ps-print-begin-column-hook'
595 ;; It is evaluated on each beginning of column, except in the beginning
596 ;; of column that `ps-print-begin-page-hook' is evaluated or that
597 ;; `ps-print-begin-sheet-hook' is evaluated.
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.
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.
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
617 ;; floats which has the following form:
619 ;; (LANDSCAPE-SIZE . PORTRAIT-SIZE)
621 ;; Similarly, the variable `ps-header-font-family' determines which font family
622 ;; is to be used for text in the header.
624 ;; The variable `ps-header-font-size' determines the font size, in points, for
625 ;; text in the header (similar to `ps-font-size').
627 ;; The variable `ps-header-title-font-size' determines the font size, in points,
628 ;; for the top line of text in the header (similar to `ps-font-size').
631 ;; Adding a New Font Family
632 ;; ------------------------
634 ;; To use a new font family, you MUST first teach ps-print
635 ;; this font, i.e., add its information to `ps-font-info-database',
636 ;; otherwise ps-print cannot correctly place line and page breaks.
638 ;; For example, assuming `Helvetica' is unknown,
639 ;; you first need to do the following ONLY ONCE:
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'
645 ;; - delete the leading `%' (which is the PostScript comment character)
646 ;; - replace in this line `Courier' by the new font (say `Helvetica')
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:
652 ;; For Helvetica 10 point, the line height is 11.56, the space width is 2.78

658 ;; '((Helvetica ; the family key
659 ;; (fonts (normal . "Helvetica")
660 ;; (bold . "Helvetica-Bold")
661 ;; (italic . "Helvetica-Oblique")
662 ;; (bold-italic . "Helvetica-BoldOblique"))
664 ;; (line-height . 11.56)
665 ;; (space-width . 2.78)
666 ;; (avg-char-width . 5.09243)))
667 ;; ps-font-info-database))
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>))
676 ;; or, use `ps-print-hook' (see section Hooks):
677 ;; (add-hook 'ps-print-hook
679 ;; (or (assq 'Helvetica ps-font-info-database)
680 ;; (setq ps-font-info-database (append ...)))))
682 ;; You can create new `mixed' font families like:
684 ;; (fonts (normal . "Courier-Bold")
685 ;; (bold . "Helvetica")
686 ;; (italic . "Zapf-Chancery-MediumItalic")
687 ;; (bold-italic . "NewCenturySchlbk-BoldItalic")
688 ;; (w3-table-hack-x-face . "LineDrawNormal"))
690 ;; (line-height . 10.55)
691 ;; (space-width . 6.0)
692 ;; (avg-char-width . 6.0))
694 ;; Now you can use your new font family with any size:
695 ;; (setq ps-font-family 'my-mixed-family)
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.
703 ;; Note also that the font family entry order is irrelevant, so the above
704 ;; example could also be written:
707 ;; (fonts (w3-table-hack-x-face . "LineDrawNormal")
708 ;; (bold . "Helvetica")
709 ;; (bold-italic . "NewCenturySchlbk-BoldItalic")

712 ;; (avg-char-width . 6.0)
713 ;; (space-width . 6.0)
714 ;; (line-height . 10.55))
716 ;; Despite the note above, it is recommended that some convention about
717 ;; entry order be used.

730 ;; How Ps-Print Deals With Faces
731 ;; -----------------------------
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.
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
745 ;; (setq ps-bold-faces '(my-blue-face))
746 ;; (setq ps-italic-faces '(my-red-face))
747 ;; (setq ps-underlined-faces '(my-green-face))
749 ;; Faces like bold-italic that are both bold and italic should go in
752 ;; ps-print keeps internal lists of which fonts are bold and which are
753 ;; italic; these lists are built the first time you invoke ps-print.
754 ;; For the sake of efficiency, the lists are built only once; the same
755 ;; lists are referred in later invocations of ps-print.
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
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 ;; -----------------------------
769 ;; ps-print detects faces with foreground and background colors
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.
777 ;; How Ps-Print Maps Faces
778 ;; -----------------------
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
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.
788 ;; outline - print characters as hollow outlines.
790 ;; See the documentation for `ps-extend-face'.
792 ;; Let's, for example, remap `font-lock-keyword-face' to another foreground
793 ;; color and bold attribute:
795 ;; (ps-extend-face '(font-lock-keyword-face "RoyalBlue" nil bold) 'MERGE)
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.
801 ;; How Ps-Print Has A Text And/Or Image On Background
802 ;; --------------------------------------------------
804 ;; ps-print can print texts and/or EPS PostScript images on background; it is
805 ;; possible to define the following text attributes: font name, font size,
806 ;; initial position, angle, gray scale and pages to print.
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.
811 ;; See documentation for `ps-print-background-text' and
812 ;; `ps-print-background-image'.
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:
817 ;; (setq ps-print-background-text
820 ;; "LeftMargin" "BottomMargin PrintHeight add" ; X and Y position
821 ;; ; (upper left corner)
823 ;; "PrintHeight neg PrintPageWidth atan" ; angle
824 ;; 5 (11 . 17)) ; page list
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
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)
838 ;; 5 (11 . 17)) ; page list
841 ;; If it is not possible to read (or does not exist) an image file, that file
844 ;; The printing order is:
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)
852 ;; 7. Print buffer text (with faces, if specified) and line number
858 ;; Some tools are provided to help you customize your font setup.
860 ;; `ps-setup' returns (some part of) the current setup.
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.
866 ;; Then, the command `ps-line-lengths' will give you the correspondence
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.
870 ;; The commands `ps-nb-pages-buffer' and `ps-nb-pages-region' display
871 ;; the correspondence between a number of pages and the maximum font
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.
875 ;; NOTE: line folding is not taken into account in this process and could
876 ;; change the results.

959 ;; Automatic font-attribute detection doesn't work well, especially
