12d89a2e | 47 | ;; About ps-print |
ef2cbb24 | 48 | ;; -------------- |
bcc0d457 | 49 | ;; |
319acba0 GM |
50 | ;; This package provides printing of Emacs buffers on PostScript printers; the |
51 | ;; buffer's bold and italic text attributes are preserved in the printer | |
eafa92bf RS |
52 | ;; output. ps-print is intended for use with Emacs or XEmacs, together with a |
53 | ;; fontifying package such as font-lock or hilit. | |
12d89a2e | 54 | ;; |
319acba0 GM |
55 | ;; ps-print uses the same face attributes defined through font-lock or hilit to |
56 | ;; print a PostScript file, but some faces are better seeing on the screen than | |
57 | ;; on paper, specially when you have a black/white PostScript printer. | |
87a16a06 RS |
58 | ;; |
59 | ;; ps-print allows a remap of face to another one that it is better to print, | |
60 | ;; for example, the face font-lock-comment-face (if you are using font-lock) | |
61 | ;; could have bold or italic attribute when printing, besides foreground color. | |
62 | ;; This remap improves printing look (see How Ps-Print Maps Faces). | |
63 | ;; | |
bcc0d457 | 64 | ;; |
12d89a2e | 65 | ;; Using ps-print |
ef2cbb24 | 66 | ;; -------------- |
ef2cbb24 | 67 | ;; |
319acba0 GM |
68 | ;; ps-print provides eight commands for generating PostScript images of Emacs |
69 | ;; buffers: | |
12d89a2e RS |
70 | ;; |
71 | ;; ps-print-buffer | |
72 | ;; ps-print-buffer-with-faces | |
73 | ;; ps-print-region | |
74 | ;; ps-print-region-with-faces | |
75 | ;; ps-spool-buffer | |
76 | ;; ps-spool-buffer-with-faces | |
77 | ;; ps-spool-region | |
78 | ;; ps-spool-region-with-faces | |
79 | ;; | |
319acba0 GM |
80 | ;; These commands all perform essentially the same function: they generate |
81 | ;; PostScript images suitable for printing on a PostScript printer or | |
82 | ;; displaying with GhostScript. These commands are collectively referred to as | |
83 | ;; "ps-print- commands". | |
12d89a2e RS |
84 | ;; |
85 | ;; The word "print" or "spool" in the command name determines when the | |
86 | ;; PostScript image is sent to the printer: | |
ef2cbb24 | 87 | ;; |
319acba0 | 88 | ;; print - The PostScript image is immediately sent to the printer; |
ef2cbb24 | 89 | ;; |
319acba0 GM |
90 | ;; spool - The PostScript image is saved temporarily in an Emacs |
91 | ;; buffer. Many images may be spooled locally before | |
92 | ;; printing them. To send the spooled images to the | |
93 | ;; printer, use the command `ps-despool'. | |
ef2cbb24 | 94 | ;; |
319acba0 GM |
95 | ;; The spooling mechanism was designed for printing lots of small files (mail |
96 | ;; messages or netnews articles) to save paper that would otherwise be wasted | |
97 | ;; on banner pages, and to make it easier to find your output at the printer | |
98 | ;; (it's easier to pick up one 50-page printout than to find 50 single-page | |
99 | ;; printouts). | |
06fb6aab | 100 | ;; |
319acba0 GM |
101 | ;; ps-print has a hook in the `kill-emacs-hook' so that you won't accidentally |
102 | ;; quit from Emacs while you have unprinted PostScript waiting in the spool | |
103 | ;; buffer. If you do attempt to exit with spooled PostScript, you'll be asked | |
104 | ;; if you want to print it, and if you decline, you'll be asked to confirm the | |
105 | ;; exit; this is modeled on the confirmation that Emacs uses for modified | |
106 | ;; buffers. | |
12d89a2e | 107 | ;; |
319acba0 GM |
108 | ;; The word "buffer" or "region" in the command name determines how much of the |
109 | ;; buffer is printed: | |
12d89a2e RS |
110 | ;; |
111 | ;; buffer - Print the entire buffer. | |
112 | ;; | |
113 | ;; region - Print just the current region. | |
114 | ;; | |
319acba0 GM |
115 | ;; The -with-faces suffix on the command name means that the command will |
116 | ;; include font, color, and underline information in the PostScript image, so | |
117 | ;; the printed image can look as pretty as the buffer. The ps-print- commands | |
118 | ;; without the -with-faces suffix don't include font, color, or underline | |
119 | ;; information; images printed with these commands aren't as pretty, but are | |
120 | ;; faster to generate. | |
12d89a2e RS |
121 | ;; |
122 | ;; Two ps-print- command examples: | |
123 | ;; | |
319acba0 GM |
124 | ;; ps-print-buffer - print the entire buffer, without font, |
125 | ;; color, or underline information, and | |
126 | ;; send it immediately to the printer. | |
12d89a2e | 127 | ;; |
319acba0 GM |
128 | ;; ps-spool-region-with-faces - print just the current region; include |
129 | ;; font, color, and underline information, | |
130 | ;; and spool the image in Emacs to send to | |
131 | ;; the printer later. | |
12d89a2e RS |
132 | ;; |

134 | ;; Invoking Ps-Print | |
bcc0d457 | 135 | ;; ----------------- |
ef2cbb24 | 136 | ;; |
12d89a2e | 137 | ;; To print your buffer, type |
ef2cbb24 | 138 | ;; |
12d89a2e | 139 | ;; M-x ps-print-buffer |
ef2cbb24 | 140 | ;; |
319acba0 GM |
141 | ;; or substitute one of the other seven ps-print- commands. The command will |
142 | ;; generate the PostScript image and print or spool it as specified. By giving | |
143 | ;; the command a prefix argument | |
12d89a2e RS |
144 | ;; |
145 | ;; C-u M-x ps-print-buffer | |
146 | ;; | |
319acba0 GM |
147 | ;; it will save the PostScript image to a file instead of sending it to the |
148 | ;; printer; you will be prompted for the name of the file to save the image to. | |
149 | ;; The prefix argument is ignored by the commands that spool their images, but | |
150 | ;; you may save the spooled images to a file by giving a prefix argument to | |
151 | ;; `ps-despool': | |
12d89a2e RS |
152 | ;; |
153 | ;; C-u M-x ps-despool | |
154 | ;; | |
319acba0 GM |
155 | ;; When invoked this way, `ps-despool' will prompt you for the name of the file |
156 | ;; to save to. | |
12d89a2e | 157 | ;; |
319acba0 GM |
158 | ;; Any of the `ps-print-' commands can be bound to keys; I recommend binding |
159 | ;; `ps-spool-buffer-with-faces', `ps-spool-region-with-faces', and | |
160 | ;; `ps-despool'. Here are the bindings I use on my Sun 4 keyboard: | |
12d89a2e RS |
161 | ;; |
162 | ;; (global-set-key 'f22 'ps-spool-buffer-with-faces) ;f22 is prsc | |
ef2cbb24 RS |
163 | ;; (global-set-key '(shift f22) 'ps-spool-region-with-faces) |
164 | ;; (global-set-key '(control f22) 'ps-despool) | |

bcc0d457 | 168 | ;; --------------------- |
12d89a2e | 169 | ;; |
319acba0 GM |
170 | ;; The variables `ps-lpr-command' and `ps-lpr-switches' determine what command |
171 | ;; is used to send the PostScript images to the printer, and what arguments to | |
172 | ;; give the command. These are analogous to `lpr-command' and `lpr-switches'. | |
87a16a06 | 173 | ;; |
bcc0d457 RS |
174 | ;; Make sure that they contain appropriate values for your system; |
175 | ;; see the usage notes below and the documentation of these variables. | |
176 | ;; | |
bc0d41bd | 177 | ;; The variable `ps-printer-name' determines the name of a local printer for |
d3ab8dac KH |
178 | ;; printing PostScript files. |
179 | ;; | |
3556c6dd GM |
180 | ;; The variable `ps-printer-name-option' determines the option used by some |
181 | ;; utilities to indicate the printer name, it's used only when | |
182 | ;; `ps-printer-name' is a non-empty string. If you're using lpr utility to | |
183 | ;; print, for example, `ps-printer-name-option' should be set to "-P". | |
184 | ;; | |
319acba0 GM |
185 | ;; NOTE: `ps-lpr-command' and `ps-lpr-switches' take their initial values from |
186 | ;; the variables `lpr-command' and `lpr-switches'. If you have | |
187 | ;; `lpr-command' set to invoke a pretty-printer such as `enscript', then | |
188 | ;; ps-print won't work properly. `ps-lpr-command' must name a program | |
189 | ;; that does not format the files it prints. | |
d3ab8dac | 190 | ;; `ps-printer-name' takes its initial value from the variable |
3556c6dd GM |
191 | ;; `printer-name'. `ps-printer-name-option' tries to guess which system |
192 | ;; Emacs is running and takes its initial value in accordance with this | |
193 | ;; guess. | |
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. | |
199 | ;; | |
8e234846 GM |
200 | ;; The variable `ps-manual-feed' indicates if the printer will manually feed |
201 | ;; paper. If it's nil, automatic feeding takes place. If it's non-nil, manual | |
202 | ;; feeding takes place. The default is nil (automatic feeding). | |
203 | ;; | |
ef1159c2 EZ |
204 | ;; The variable `ps-end-with-control-d' specifies whether C-d (\x04) should be |
205 | ;; inserted at end of PostScript generated. Non-nil means do so. The default | |
206 | ;; is nil (don't insert). | |
207 | ;; | |
98f2fbe7 | 208 | ;; If you're using Emacs for Windows 95/98/NT or MS-DOS, don't forget to |
3556c6dd GM |
209 | ;; customize the following variables: `ps-printer-name', |
210 | ;; `ps-printer-name-option', `ps-lpr-command', `ps-lpr-switches' and | |
211 | ;; `ps-spool-config'. See these variables documentation in the code or by | |

229 | ;; `ps-paper-type', instead it uses the default paper size. If variable | |
230 | ;; `ps-warn-paper-type' is non-nil, it's given an error if PostScript printer | |
231 | ;; doesn't have a paper with the size indicated by `ps-paper-type'. It's used | |
232 | ;; when `ps-spool-config' is set to `setpagedevice' (see section Duplex | |
233 | ;; Printers). The default value is non-nil (it gives an error). | |
234 | ;; | |
906d41a7 GM |
235 | ;; The variable `ps-landscape-mode' determines the orientation of the printing |
236 | ;; on the page: nil means `portrait' mode, non-nil means `landscape' mode. | |

242 | ;; of the page and the printed header, whatever the orientation is. | |
043620f4 | 243 | ;; |
906d41a7 GM |
244 | ;; The variable `ps-number-of-columns' determines the number of columns both in |

bcc0d457 | 246 | ;; You can use: |
906d41a7 GM |
247 | ;; - (the standard) one column portrait mode. |

319acba0 GM |
253 | ;; The variable `ps-print-upside-down' determines other orientation for |
254 | ;; printing page: nil means `normal' printing, non-nil means `upside-down' | |
255 | ;; printing (that is, the page is rotated by 180 grades). The default value is | |
256 | ;; nil (`normal' printing). | |
906d41a7 GM |

12d89a2e | 259 | ;; |
1fd9b7fe GM |
260 | ;; The variable `ps-selected-pages' specifies which pages to print. If it's |
261 | ;; nil, all pages are printed. If it's a list, the list element may be an | |
262 | ;; integer or a cons cell (FROM . TO) designating FROM page to TO page; any | |
263 | ;; invalid element is ignored, that is, an integer lesser than one or if FROM | |
264 | ;; is greater than TO. Otherwise, it's treated as nil. The default value is | |
265 | ;; nil (print all pages). After ps-print processing `ps-selected-pages' is set | |
266 | ;; to nil. But the latest `ps-selected-pages' is saved in | |
267 | ;; `ps-last-selected-pages' (see it for documentation). So you can restore the | |
268 | ;; latest selected pages by using `ps-last-selected-pages' or by calling | |

365 | ;; fore-color Specify the foreground frame color. | |
366 | ;; It should be a float number between 0.0 (black color) | |
367 | ;; and 1.0 (white color), a string which is a color name, | |
368 | ;; or a list of 3 float numbers which corresponds to the | |
369 | ;; Red Green Blue color scale, each float number between | |

371 | ;; The default is 0 ("black"). | |
372 | ;; | |
373 | ;; back-color Specify the background frame color (similar to | |
374 | ;; fore-color). The default is 0.9 ("gray90"). | |
375 | ;; | |
376 | ;; shadow-color Specify the shadow color (similar to fore-color). | |
377 | ;; The default is 0 ("black"). | |

380 | ;; The default is 0 ("black"). | |
381 | ;; | |
382 | ;; border-width Specify the border width. | |
383 | ;; The default is 0.4. | |

418 | ;; will show only the buffer name and page number. To show more, set | |
419 | ;; `ps-header-lines' to 3, and the header will show the time of printing below | |
420 | ;; the date. | |
421 | ;; | |
422 | ;; To change the content of the headers, change the variables `ps-left-header' | |
423 | ;; and `ps-right-header'. | |
424 | ;; These variables are lists, specifying top-to-bottom the text to display on | |
425 | ;; the left or right side of the header. Each element of the list should be a | |
426 | ;; string or a symbol. Strings are inserted directly into the PostScript | |
427 | ;; arrays, and should contain the PostScript string delimiters '(' and ')'. | |
428 | ;; | |
429 | ;; Symbols in the header format lists can either represent functions or | |
430 | ;; variables. Functions are called, and should return a string to show in the | |
431 | ;; header. Variables should contain strings to display in the header. In | |

436 | ;; | |
437 | ;; Moe | |
438 | ;; Larry | |
439 | ;; Curly | |
440 | ;; | |

447 | ;; | |
448 | ;; (setq larry-var "Larry") | |
449 | ;; | |
319acba0 | 450 | ;; and a literal for "Curly". Here's how `ps-left-header' should be set: |
12d89a2e RS |
451 | ;; |
452 | ;; (setq ps-left-header (list 'moe-func 'larry-var "(Curly)")) | |
453 | ;; | |
319acba0 GM |
454 | ;; Note that Curly has the PostScript string delimiters inside his quotes -- |
455 | ;; those aren't misplaced lisp delimiters! | |
87a16a06 | 456 | ;; |
319acba0 GM |
457 | ;; Without them, PostScript would attempt to call the undefined function Curly, |
458 | ;; which would result in a PostScript error. | |
87a16a06 | 459 | ;; |
319acba0 GM |
460 | ;; Since most printers don't report PostScript errors except by aborting the |
461 | ;; print job, this kind of error can be hard to track down. | |

877 | ;; `ps-font-info-database' contains information for a list of font families | |
319acba0 GM |
878 | ;; (currently mainly `Courier' `Helvetica' `Times' `Palatino' |
879 | ;; `Helvetica-Narrow' `NewCenturySchlbk'). Each font family contains the font | |
880 | ;; names for standard, bold, italic and bold-italic characters, a reference | |
881 | ;; size (usually 10) and the corresponding line height, width of a space and | |
882 | ;; average character width. | |
06fb6aab | 883 | ;; |
7d8b7e8e KH |
884 | ;; The variable `ps-font-family' determines which font family is to be used for |
885 | ;; ordinary text. If its value does not correspond to a known font family, an | |
886 | ;; error message is printed into the `*Messages*' buffer, which lists the | |
887 | ;; currently available font families. | |
bcc0d457 | 888 | ;; |
7d8b7e8e | 889 | ;; The variable `ps-font-size' determines the size (in points) of the font for |
319acba0 GM |
890 | ;; ordinary text, when generating PostScript. Its value is a float or a cons |

bcc0d457 | 892 | ;; |
7d8b7e8e KH |
893 | ;; (LANDSCAPE-SIZE . PORTRAIT-SIZE) |
894 | ;; | |
895 | ;; Similarly, the variable `ps-header-font-family' determines which font family | |
896 | ;; is to be used for text in the header. | |
897 | ;; | |
898 | ;; The variable `ps-header-font-size' determines the font size, in points, for | |

900 | ;; | |
319acba0 GM |
901 | ;; The variable `ps-header-title-font-size' determines the font size, in |

bcc0d457 | 903 | ;; |
6bf5fb46 GM |
904 | ;; The variable `ps-line-spacing' determines the line spacing, in points, for |

12b88fff | 934 | ;; Adding a New Font Family |
bcc0d457 RS |
935 | ;; ------------------------ |
936 | ;; | |
319acba0 GM |
937 | ;; To use a new font family, you MUST first teach ps-print this font, i.e., add |
938 | ;; its information to `ps-font-info-database', otherwise ps-print cannot | |
939 | ;; correctly place line and page breaks. | |
bcc0d457 | 940 | ;; |
319acba0 GM |
941 | ;; For example, assuming `Helvetica' is unknown, you first need to do the |
942 | ;; following ONLY ONCE: | |
bcc0d457 RS |
943 | ;; |
944 | ;; - create a new buffer | |
945 | ;; - generate the PostScript image to a file (C-u M-x ps-print-buffer) | |
946 | ;; - open this file and find the line: | |
1fd9b7fe | 947 | ;; `% 3 cm 20 cm moveto 10/Courier ReportFontInfo showpage' |
a18ed129 | 948 | ;; - delete the leading `%' (which is the PostScript comment character) |
319acba0 GM |
949 | ;; - replace in this line `Courier' by the new font (say `Helvetica') to get |
950 | ;; the line: | |
1fd9b7fe | 951 | ;; `3 cm 20 cm moveto 10/Helvetica ReportFontInfo showpage' |
bcc0d457 RS |
952 | ;; - send this file to the printer (or to ghostscript). |
953 | ;; You should read the following on the output page: | |
954 | ;; | |
955 | ;; For Helvetica 10 point, the line height is 11.56, the space width is 2.78 | |
956 | ;; and a crude estimate of average character width is 5.09243 | |
957 | ;; | |
958 | ;; - Add these values to the `ps-font-info-database': | |
959 | ;; (setq ps-font-info-database | |
12b88fff RS |
960 | ;; (append |
961 | ;; '((Helvetica ; the family key | |
962 | ;; (fonts (normal . "Helvetica") | |
963 | ;; (bold . "Helvetica-Bold") | |
964 | ;; (italic . "Helvetica-Oblique") | |
965 | ;; (bold-italic . "Helvetica-BoldOblique")) | |
966 | ;; (size . 10.0) | |
967 | ;; (line-height . 11.56) | |
968 | ;; (space-width . 2.78) | |
969 | ;; (avg-char-width . 5.09243))) | |
970 | ;; ps-font-info-database)) | |
bcc0d457 RS |
971 | ;; - Now you can use this font family with any size: |
972 | ;; (setq ps-font-family 'Helvetica) | |
319acba0 GM |
973 | ;; - if you want to use this family in another emacs session, you must put into |
974 | ;; your `~/.emacs': | |
bcc0d457 RS |
975 | ;; (require 'ps-print) |
976 | ;; (setq ps-font-info-database (append ...))) | |
977 | ;; if you don't want to load ps-print, you have to copy the whole value: | |
978 | ;; (setq ps-font-info-database '(<your stuff> <the standard stuff>)) | |
12b88fff RS |
979 | ;; or, use `ps-print-hook' (see section Hooks): |
980 | ;; (add-hook 'ps-print-hook | |
bc0d41bd KH |
981 | ;; '(lambda () |
982 | ;; (or (assq 'Helvetica ps-font-info-database) | |
983 | ;; (setq ps-font-info-database (append ...))))) | |
bcc0d457 RS |
984 | ;; |
985 | ;; You can create new `mixed' font families like: | |
12b88fff RS |
986 | ;; (my-mixed-family |
987 | ;; (fonts (normal . "Courier-Bold") | |

992 | ;; (size . 10.0) | |
993 | ;; (line-height . 10.55) | |
994 | ;; (space-width . 6.0) | |
995 | ;; (avg-char-width . 6.0)) | |
d3ab8dac | 996 | ;; |
bcc0d457 RS |
997 | ;; Now you can use your new font family with any size: |
998 | ;; (setq ps-font-family 'my-mixed-family) | |
999 | ;; | |
319acba0 GM |
1000 | ;; Note that on above example the `w3-table-hack-x-face' entry refers to a face |
1001 | ;; symbol, so when printing this face it'll be used the font `LineDrawNormal'. | |
1002 | ;; If the face `w3-table-hack-x-face' is remapped to use bold and/or italic | |
1003 | ;; attribute, the corresponding entry (bold, italic or bold-italic) will be | |
1004 | ;; used instead of `w3-table-hack-x-face' entry. | |
12b88fff RS |
1005 | ;; |
1006 | ;; Note also that the font family entry order is irrelevant, so the above | |
1007 | ;; example could also be written: | |
1008 | ;; (my-mixed-family | |
1009 | ;; (size . 10.0) | |
1010 | ;; (fonts (w3-table-hack-x-face . "LineDrawNormal") | |
1011 | ;; (bold . "Helvetica") | |
1012 | ;; (bold-italic . "NewCenturySchlbk-BoldItalic") | |
1013 | ;; (italic . "Zapf-Chancery-MediumItalic") | |
1014 | ;; (normal . "Courier-Bold")) | |
1015 | ;; (avg-char-width . 6.0) | |
1016 | ;; (space-width . 6.0) | |
1017 | ;; (line-height . 10.55)) | |
1018 | ;; | |
1019 | ;; Despite the note above, it is recommended that some convention about | |
1020 | ;; entry order be used. | |
1021 | ;; | |
bcc0d457 RS |
1022 | ;; You can get information on all the fonts resident in YOUR printer |
1023 | ;; by uncommenting the line: | |

a18ed129 | 1026 | ;; The PostScript file should be sent to YOUR PostScript printer. |

1027 | ;; If you send it to ghostscript or to another PostScript printer, you may get |
1028 | ;; slightly different results. | |
c3d6d211 GM |
1029 | ;; Anyway, as ghostscript fonts are autoload, you won't get much font info. |
1030 | ;; | |

1035 | ;; How Ps-Print Deals With Faces | |
1036 | ;; ----------------------------- | |
12d89a2e | 1037 | ;; |
319acba0 GM |
1038 | ;; The ps-print-*-with-faces commands attempt to determine which faces should |
1039 | ;; be printed in bold or italic, but their guesses aren't always right. For | |
1040 | ;; example, you might want to map colors into faces so that blue faces print in | |
1041 | ;; bold, and red faces in italic. | |
12d89a2e | 1042 | ;; |
319acba0 GM |
1043 | ;; It is possible to force ps-print to consider specific faces bold, italic or |
1044 | ;; underline, no matter what font they are displayed in, by setting the | |
1045 | ;; variables `ps-bold-faces', `ps-italic-faces' and `ps-underlined-faces'. | |
857686a6 RS |
1046 | ;; These variables contain lists of faces that ps-print should consider bold, |
1047 | ;; italic or underline; to set them, put code like the following into your | |
1048 | ;; .emacs file: | |
12d89a2e | 1049 | ;; |
12b88fff | 1050 | ;; (setq ps-bold-faces '(my-blue-face)) |
bcc0d457 | 1051 | ;; (setq ps-italic-faces '(my-red-face)) |
857686a6 | 1052 | ;; (setq ps-underlined-faces '(my-green-face)) |
bcc0d457 | 1053 | ;; |
319acba0 GM |
1054 | ;; Faces like bold-italic that are both bold and italic should go in *both* |
1055 | ;; lists. | |
bcc0d457 | 1056 | ;; |
319acba0 GM |
1057 | ;; ps-print keeps internal lists of which fonts are bold and which are italic; |
1058 | ;; these lists are built the first time you invoke ps-print. | |
1059 | ;; For the sake of efficiency, the lists are built only once; the same lists | |
1060 | ;; are referred in later invocations of ps-print. | |
bcc0d457 | 1061 | ;; |
319acba0 GM |
1062 | ;; Because these lists are built only once, it's possible for them to get out |
1063 | ;; of sync, if a face changes, or if new faces are added. To get the lists | |
1064 | ;; back in sync, you can set the variable `ps-build-face-reference' to t, and | |
1065 | ;; the lists will be rebuilt the next time ps-print is invoked. If you need | |
1066 | ;; that the lists always be rebuilt when ps-print is invoked, set the variable | |
857686a6 | 1067 | ;; `ps-always-build-face-reference' to t. |
bcc0d457 | 1068 | ;; |
906d41a7 GM |
1069 | ;; If you need to print without worrying about face background color, set the |
1070 | ;; variable `ps-use-face-background' which specifies if face background should | |
1071 | ;; be used. Valid values are: | |
1072 | ;; | |
1073 | ;; t always use face background color. | |
1074 | ;; nil never use face background color. | |
1075 | ;; (face...) list of faces whose background color will be used. | |
1076 | ;; | |
1077 | ;; Any other value will be treated as t. | |

1094 | ;; How Ps-Print Maps Faces |
1095 | ;; ----------------------- | |
1096 | ;; | |
319acba0 GM |
1097 | ;; As ps-print uses PostScript to print buffers, it is possible to have other |
1098 | ;; attributes associated with faces. So the new attributes used by ps-print | |
1099 | ;; are: | |
87a16a06 RS |
1100 | ;; |
1101 | ;; strikeout - like underline, but the line is in middle of text. | |
1102 | ;; overline - like underline, but the line is over the text. | |
1103 | ;; shadow - text will have a shadow. | |
1104 | ;; box - text will be surrounded by a box. | |
a18ed129 | 1105 | ;; outline - print characters as hollow outlines. |
87a16a06 | 1106 | ;; |
06fb6aab | 1107 | ;; See the documentation for `ps-extend-face'. |
87a16a06 | 1108 | ;; |
bc0d41bd KH |
1109 | ;; Let's, for example, remap `font-lock-keyword-face' to another foreground |
1110 | ;; color and bold attribute: | |
87a16a06 | 1111 | ;; |
a18ed129 | 1112 | ;; (ps-extend-face '(font-lock-keyword-face "RoyalBlue" nil bold) 'MERGE) |
87a16a06 | 1113 | ;; |
319acba0 GM |
1114 | ;; If you want to use a new face, define it first with `defface', and then call |
1115 | ;; `ps-extend-face' to specify how to print it. | |

1118 | ;; How Ps-Print Has A Text And/Or Image On Background | |
1119 | ;; -------------------------------------------------- | |
1120 | ;; | |
d3ab8dac | 1121 | ;; ps-print can print texts and/or EPS PostScript images on background; it is |
87a16a06 RS |
1122 | ;; possible to define the following text attributes: font name, font size, |
1123 | ;; initial position, angle, gray scale and pages to print. | |
1124 | ;; | |
1125 | ;; It has the following EPS PostScript images attributes: file name containing | |
1126 | ;; the image, initial position, X and Y scales, angle and pages to print. | |
1127 | ;; | |
1128 | ;; See documentation for `ps-print-background-text' and | |
1129 | ;; `ps-print-background-image'. | |
1130 | ;; | |
1131 | ;; For example, if we wish to print text "preliminary" on all pages and text | |
1132 | ;; "special" on page 5 and from page 11 to page 17, we could specify: | |
1133 | ;; | |
1134 | ;; (setq ps-print-background-text | |
1135 | ;; '(("preliminary") | |
1136 | ;; ("special" | |
1137 | ;; "LeftMargin" "BottomMargin PrintHeight add" ; X and Y position | |
1138 | ;; ; (upper left corner) | |
1139 | ;; nil nil nil | |
12b88fff | 1140 | ;; "PrintHeight neg PrintPageWidth atan" ; angle |
87a16a06 RS |
1141 | ;; 5 (11 . 17)) ; page list |
1142 | ;; )) | |
1143 | ;; | |
1144 | ;; Similarly, we could print image "~/images/EPS-image1.ps" on all pages and | |
1145 | ;; image "~/images/EPS-image2.ps" on page 5 and from page 11 to page 17, we | |
1146 | ;; specify: | |
1147 | ;; | |
1148 | ;; (setq ps-print-background-image | |
1149 | ;; '(("~/images/EPS-image1.ps" | |
1150 | ;; "LeftMargin" "BottomMargin") ; X and Y position (lower left corner) | |
1151 | ;; ("~/images/EPS-image2.ps" | |
319acba0 | 1152 | ;; "LeftMargin" "BottomMargin PrintHeight 2 div add" ; X and Y pos. |
87a16a06 RS |
1153 | ;; ; (upper left corner) |
1154 | ;; nil nil nil | |
1155 | ;; 5 (11 . 17)) ; page list | |
1156 | ;; )) | |
1157 | ;; | |
1158 | ;; If it is not possible to read (or does not exist) an image file, that file | |
1159 | ;; is ignored. | |
1160 | ;; | |
1161 | ;; The printing order is: | |
1162 | ;; | |
6e1b1da6 GM |
1163 | ;; 1. Print background color |
1164 | ;; 2. Print zebra stripes | |
1165 | ;; 3. Print background texts that it should be on all pages | |
1166 | ;; 4. Print background images that it should be on all pages | |
1167 | ;; 5. Print background texts only for current page (if any) | |
1168 | ;; 6. Print background images only for current page (if any) | |
1169 | ;; 7. Print header | |
1170 | ;; 8. Print buffer text (with faces, if specified) and line number | |

1173 | ;; Utilities |
1174 | ;; --------- | |
1175 | ;; | |
1176 | ;; Some tools are provided to help you customize your font setup. | |
1177 | ;; | |
1178 | ;; `ps-setup' returns (some part of) the current setup. | |
1179 | ;; | |
319acba0 GM |
1180 | ;; To avoid wrapping too many lines, you may want to adjust the left and right |
1181 | ;; margins and the font size. On UN*X systems, do: | |
bcc0d457 RS |
1182 | ;; pr -t file | awk '{printf "%3d %s\n", length($0), $0}' | sort -r | head |
1183 | ;; to determine the longest lines of your file. | |
319acba0 GM |
1184 | ;; Then, the command `ps-line-lengths' will give you the correspondence between |
1185 | ;; a line length (number of characters) and the maximum font size which doesn't | |
1186 | ;; wrap such a line with the current ps-print setup. | |
bcc0d457 | 1187 | ;; |
319acba0 GM |
1188 | ;; The commands `ps-nb-pages-buffer' and `ps-nb-pages-region' display the |
1189 | ;; correspondence between a number of pages and the maximum font size which | |
1190 | ;; allow the number of lines of the current buffer or of its current region to | |
1191 | ;; fit in this number of pages. | |
a18ed129 RS |
1192 | ;; |
