12d89a2e | 49 | ;; About ps-print |
ef2cbb24 | 50 | ;; -------------- |
bcc0d457 | 51 | ;; |
0a5daee5 KH |
52 | ;; This package provides printing of Emacs buffers on PostScript printers; |
53 | ;; the buffer's bold and italic text attributes are preserved in the printer | |
54 | ;; output. ps-print is intended for use with Emacs or Lucid Emacs, together | |
55 | ;; with a fontifying package such as 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 | ;; | |
3556c6dd GM |
187 | ;; The variable `ps-printer-name-option' determines the option used by some |
188 | ;; utilities to indicate the printer name, it's used only when | |
189 | ;; `ps-printer-name' is a non-empty string. If you're using lpr utility to | |
190 | ;; print, for example, `ps-printer-name-option' should be set to "-P". | |
191 | ;; | |
bcc0d457 RS |
192 | ;; NOTE: `ps-lpr-command' and `ps-lpr-switches' take their initial values |
193 | ;; from the variables `lpr-command' and `lpr-switches'. If you have | |
194 | ;; `lpr-command' set to invoke a pretty-printer such as `enscript', | |
195 | ;; then ps-print won't work properly. `ps-lpr-command' must name | |
12d89a2e | 196 | ;; a program that does not format the files it prints. |
d3ab8dac | 197 | ;; `ps-printer-name' takes its initial value from the variable |
3556c6dd GM |
198 | ;; `printer-name'. `ps-printer-name-option' tries to guess which system |
199 | ;; Emacs is running and takes its initial value in accordance with this | |
200 | ;; guess. | |
12d89a2e | 201 | ;; |
bc0d41bd KH |
202 | ;; The variable `ps-print-region-function' specifies a function to print the |
203 | ;; region on a PostScript printer. | |
204 | ;; See definition of `call-process-region' for calling conventions. The fourth | |
205 | ;; and the sixth arguments are both nil. | |
206 | ;; | |
8e234846 GM |
207 | ;; The variable `ps-manual-feed' indicates if the printer will manually feed |
208 | ;; paper. If it's nil, automatic feeding takes place. If it's non-nil, manual | |
209 | ;; feeding takes place. The default is nil (automatic feeding). | |
210 | ;; | |
ef1159c2 EZ |
211 | ;; The variable `ps-end-with-control-d' specifies whether C-d (\x04) should be |
212 | ;; inserted at end of PostScript generated. Non-nil means do so. The default | |
213 | ;; is nil (don't insert). | |
214 | ;; | |
98f2fbe7 | 215 | ;; If you're using Emacs for Windows 95/98/NT or MS-DOS, don't forget to |
3556c6dd GM |
216 | ;; customize the following variables: `ps-printer-name', |
217 | ;; `ps-printer-name-option', `ps-lpr-command', `ps-lpr-switches' and | |
218 | ;; `ps-spool-config'. See these variables documentation in the code or by | |

237 | ;; `ps-warn-paper-type' is non-nil, it's given an error if PostScript printer | |
238 | ;; doesn't have a paper with the size indicated by `ps-paper-type'. It's used | |
239 | ;; when `ps-spool-config' is set to `setpagedevice' (see section Duplex | |
240 | ;; Printers). The default value is non-nil (it gives an error). | |
241 | ;; | |
906d41a7 GM |
242 | ;; The variable `ps-landscape-mode' determines the orientation of the printing |

906d41a7 GM |
258 | ;; - multi-column portrait or landscape mode. |
259 | ;; | |
260 | ;; The variable `ps-print-upside-down' determines other orientation for printing | |

12d89a2e | 265 | ;; |
1fd9b7fe GM |
266 | ;; The variable `ps-selected-pages' specifies which pages to print. If it's |
267 | ;; nil, all pages are printed. If it's a list, the list element may be an | |

269 | ;; invalid element is ignored, that is, an integer lesser than one or if FROM | |
270 | ;; is greater than TO. Otherwise, it's treated as nil. The default value is | |
271 | ;; nil (print all pages). After ps-print processing `ps-selected-pages' is set | |
272 | ;; to nil. But the latest `ps-selected-pages' is saved in | |
273 | ;; `ps-last-selected-pages' (see it for documentation). So you can restore the | |
274 | ;; latest selected pages by using `ps-last-selected-pages' or by calling | |

425 | ;; set: |
426 | ;; | |
427 | ;; (setq ps-left-header (list 'moe-func 'larry-var "(Curly)")) | |

449 | ;; section which is used to define some document characteristic through | |
d3ab8dac KH |
450 | ;; PostScript special comments, like "%%Requirements: jog\n". |
451 | ;; | |
452 | ;; By default `ps-print-prologue-header' is nil. | |
453 | ;; | |
454 | ;; ps-print always inserts the %%Requirements: comment, so if you need to insert | |
455 | ;; more requirements put them first in `ps-print-prologue-header' using the | |
456 | ;; "%%+" comment. For example, if you need to set numcopies to 3 and jog on | |
457 | ;; requirements and set %%LanguageLevel: to 2, do: | |
458 | ;; | |
459 | ;; (setq ps-print-prologue-header | |
460 | ;; "%%+ numcopies(3) jog\n%%LanguageLevel: 2\n") | |

819 | ;; ps-print now knows rather precisely some fonts: the variable |
820 | ;; `ps-font-info-database' contains information for a list of font families | |
821 | ;; (currently mainly `Courier' `Helvetica' `Times' `Palatino' `Helvetica-Narrow' | |
822 | ;; `NewCenturySchlbk'). Each font family contains the font names for standard, | |
823 | ;; bold, italic and bold-italic characters, a reference size (usually 10) and | |
824 | ;; the corresponding line height, width of a space and average character width. | |
06fb6aab | 825 | ;; |
7d8b7e8e KH |
826 | ;; The variable `ps-font-family' determines which font family is to be used for |
827 | ;; ordinary text. If its value does not correspond to a known font family, an | |
828 | ;; error message is printed into the `*Messages*' buffer, which lists the | |
829 | ;; currently available font families. | |
bcc0d457 | 830 | ;; |
7d8b7e8e KH |
831 | ;; The variable `ps-font-size' determines the size (in points) of the font for |
832 | ;; ordinary text, when generating PostScript. Its value is a float or a cons of | |
833 | ;; floats which has the following form: | |
bcc0d457 | 834 | ;; |
7d8b7e8e KH |
835 | ;; (LANDSCAPE-SIZE . PORTRAIT-SIZE) |
836 | ;; | |
837 | ;; Similarly, the variable `ps-header-font-family' determines which font family | |
838 | ;; is to be used for text in the header. | |
839 | ;; | |
840 | ;; The variable `ps-header-font-size' determines the font size, in points, for | |
841 | ;; text in the header (similar to `ps-font-size'). | |
842 | ;; | |
843 | ;; The variable `ps-header-title-font-size' determines the font size, in points, | |
844 | ;; for the top line of text in the header (similar to `ps-font-size'). | |

12b88fff | 847 | ;; Adding a New Font Family |
bcc0d457 RS |
848 | ;; ------------------------ |
849 | ;; | |
850 | ;; To use a new font family, you MUST first teach ps-print | |
87a16a06 | 851 | ;; this font, i.e., add its information to `ps-font-info-database', |
bcc0d457 RS |
852 | ;; otherwise ps-print cannot correctly place line and page breaks. |
853 | ;; | |
87a16a06 | 854 | ;; For example, assuming `Helvetica' is unknown, |
bcc0d457 RS |
855 | ;; you first need to do the following ONLY ONCE: |
856 | ;; | |
857 | ;; - create a new buffer | |
858 | ;; - generate the PostScript image to a file (C-u M-x ps-print-buffer) | |
859 | ;; - open this file and find the line: | |
1fd9b7fe | 860 | ;; `% 3 cm 20 cm moveto 10/Courier ReportFontInfo showpage' |
a18ed129 | 861 | ;; - delete the leading `%' (which is the PostScript comment character) |
bcc0d457 RS |
862 | ;; - replace in this line `Courier' by the new font (say `Helvetica') |
863 | ;; to get the line: | |
1fd9b7fe | 864 | ;; `3 cm 20 cm moveto 10/Helvetica ReportFontInfo showpage' |
bcc0d457 RS |
865 | ;; - send this file to the printer (or to ghostscript). |
866 | ;; You should read the following on the output page: | |
867 | ;; | |
868 | ;; For Helvetica 10 point, the line height is 11.56, the space width is 2.78 | |
869 | ;; and a crude estimate of average character width is 5.09243 | |
870 | ;; | |
871 | ;; - Add these values to the `ps-font-info-database': | |
872 | ;; (setq ps-font-info-database | |
12b88fff RS |
873 | ;; (append |
874 | ;; '((Helvetica ; the family key | |
875 | ;; (fonts (normal . "Helvetica") | |
876 | ;; (bold . "Helvetica-Bold") | |
877 | ;; (italic . "Helvetica-Oblique") | |
878 | ;; (bold-italic . "Helvetica-BoldOblique")) | |
879 | ;; (size . 10.0) | |
880 | ;; (line-height . 11.56) | |
881 | ;; (space-width . 2.78) | |
882 | ;; (avg-char-width . 5.09243))) | |
883 | ;; ps-font-info-database)) | |
bcc0d457 RS |
884 | ;; - Now you can use this font family with any size: |
885 | ;; (setq ps-font-family 'Helvetica) | |
886 | ;; - if you want to use this family in another emacs session, you must | |
887 | ;; put into your `~/.emacs': | |
888 | ;; (require 'ps-print) | |
889 | ;; (setq ps-font-info-database (append ...))) | |
890 | ;; if you don't want to load ps-print, you have to copy the whole value: | |
891 | ;; (setq ps-font-info-database '(<your stuff> <the standard stuff>)) | |
12b88fff RS |
892 | ;; or, use `ps-print-hook' (see section Hooks): |
893 | ;; (add-hook 'ps-print-hook | |
bc0d41bd KH |
894 | ;; '(lambda () |
895 | ;; (or (assq 'Helvetica ps-font-info-database) | |
896 | ;; (setq ps-font-info-database (append ...))))) | |
bcc0d457 RS |
897 | ;; |
898 | ;; You can create new `mixed' font families like: | |
12b88fff RS |
899 | ;; (my-mixed-family |
900 | ;; (fonts (normal . "Courier-Bold") | |
901 | ;; (bold . "Helvetica") | |

903 | ;; (bold-italic . "NewCenturySchlbk-BoldItalic") | |
904 | ;; (w3-table-hack-x-face . "LineDrawNormal")) | |
905 | ;; (size . 10.0) | |
906 | ;; (line-height . 10.55) | |
907 | ;; (space-width . 6.0) | |
908 | ;; (avg-char-width . 6.0)) | |
d3ab8dac | 909 | ;; |
bcc0d457 RS |
910 | ;; Now you can use your new font family with any size: |
911 | ;; (setq ps-font-family 'my-mixed-family) | |
912 | ;; | |
12b88fff RS |
913 | ;; Note that on above example the `w3-table-hack-x-face' entry refers to |
914 | ;; a face symbol, so when printing this face it'll be used the font | |
915 | ;; `LineDrawNormal'. If the face `w3-table-hack-x-face' is remapped to | |
916 | ;; use bold and/or italic attribute, the corresponding entry (bold, italic | |
917 | ;; or bold-italic) will be used instead of `w3-table-hack-x-face' entry. | |
918 | ;; | |
919 | ;; Note also that the font family entry order is irrelevant, so the above | |
920 | ;; example could also be written: | |
921 | ;; (my-mixed-family | |
922 | ;; (size . 10.0) | |
923 | ;; (fonts (w3-table-hack-x-face . "LineDrawNormal") | |
924 | ;; (bold . "Helvetica") | |
925 | ;; (bold-italic . "NewCenturySchlbk-BoldItalic") | |
926 | ;; (italic . "Zapf-Chancery-MediumItalic") | |
927 | ;; (normal . "Courier-Bold")) | |
928 | ;; (avg-char-width . 6.0) | |
929 | ;; (space-width . 6.0) | |
930 | ;; (line-height . 10.55)) | |
931 | ;; | |
932 | ;; Despite the note above, it is recommended that some convention about | |
933 | ;; entry order be used. | |
934 | ;; | |
bcc0d457 RS |
935 | ;; You can get information on all the fonts resident in YOUR printer |
936 | ;; by uncommenting the line: | |
937 | ;; % 3 cm 20 cm moveto ReportAllFontInfo showpage | |
938 | ;; | |
a18ed129 RS |
939 | ;; The PostScript file should be sent to YOUR PostScript printer. |
940 | ;; If you send it to ghostscript or to another PostScript printer, | |
bcc0d457 | 941 | ;; you may get slightly different results. |
c3d6d211 GM |
942 | ;; Anyway, as ghostscript fonts are autoload, you won't get much font info. |
943 | ;; | |
944 | ;; Note also that ps-print DOESN'T download any font to your printer, instead | |
945 | ;; it uses the fonts resident in your printer. | |

948 | ;; How Ps-Print Deals With Faces | |
949 | ;; ----------------------------- | |
12d89a2e | 950 | ;; |
bcc0d457 RS |
951 | ;; The ps-print-*-with-faces commands attempt to determine which faces |
952 | ;; should be printed in bold or italic, but their guesses aren't | |
953 | ;; always right. For example, you might want to map colors into faces | |
954 | ;; so that blue faces print in bold, and red faces in italic. | |
12d89a2e | 955 | ;; |
857686a6 RS |
956 | ;; It is possible to force ps-print to consider specific faces bold, |
957 | ;; italic or underline, no matter what font they are displayed in, by setting | |
958 | ;; the variables `ps-bold-faces', `ps-italic-faces' and `ps-underlined-faces'. | |
959 | ;; These variables contain lists of faces that ps-print should consider bold, | |
960 | ;; italic or underline; to set them, put code like the following into your | |
961 | ;; .emacs file: | |
12d89a2e | 962 | ;; |
12b88fff | 963 | ;; (setq ps-bold-faces '(my-blue-face)) |
bcc0d457 | 964 | ;; (setq ps-italic-faces '(my-red-face)) |
857686a6 | 965 | ;; (setq ps-underlined-faces '(my-green-face)) |
bcc0d457 RS |
966 | ;; |
967 | ;; Faces like bold-italic that are both bold and italic should go in | |
968 | ;; *both* lists. | |
969 | ;; | |
d3ab8dac | 970 | ;; ps-print keeps internal lists of which fonts are bold and which are |
bcc0d457 RS |
971 | ;; italic; these lists are built the first time you invoke ps-print. |
972 | ;; For the sake of efficiency, the lists are built only once; the same | |
973 | ;; lists are referred in later invocations of ps-print. | |
974 | ;; | |
975 | ;; Because these lists are built only once, it's possible for them to | |
976 | ;; get out of sync, if a face changes, or if new faces are added. To | |
977 | ;; get the lists back in sync, you can set the variable | |
978 | ;; `ps-build-face-reference' to t, and the lists will be rebuilt the | |
857686a6 RS |
979 | ;; next time ps-print is invoked. If you need that the lists always be |
980 | ;; rebuilt when ps-print is invoked, set the variable | |
981 | ;; `ps-always-build-face-reference' to t. | |
bcc0d457 | 982 | ;; |
906d41a7 GM |
983 | ;; If you need to print without worrying about face background color, set the |
984 | ;; variable `ps-use-face-background' which specifies if face background should | |
985 | ;; be used. Valid values are: | |
986 | ;; | |
987 | ;; t always use face background color. | |
988 | ;; nil never use face background color. | |
989 | ;; (face...) list of faces whose background color will be used. | |
990 | ;; | |
991 | ;; Any other value will be treated as t. | |
992 | ;; The default value is t. | |
993 | ;; | |

995 | ;; How Ps-Print Deals With Color | |
996 | ;; ----------------------------- | |
997 | ;; | |
d3ab8dac | 998 | ;; ps-print detects faces with foreground and background colors |
bcc0d457 RS |
999 | ;; defined and embeds color information in the PostScript image. |
1000 | ;; The default foreground and background colors are defined by the | |
1001 | ;; variables `ps-default-fg' and `ps-default-bg'. | |
6e1b1da6 | 1002 | ;; On black-and-white printers, colors are displayed in gray scale. |
bcc0d457 RS |
1003 | ;; To turn off color output, set `ps-print-color-p' to nil. |

1005 | ;; | |
87a16a06 RS |
1006 | ;; How Ps-Print Maps Faces |
1007 | ;; ----------------------- | |
1008 | ;; | |
1009 | ;; As ps-print uses PostScript to print buffers, it is possible to have | |
1010 | ;; other attributes associated with faces. So the new attributes used | |
1011 | ;; by ps-print are: | |
1012 | ;; | |
1013 | ;; strikeout - like underline, but the line is in middle of text. | |
1014 | ;; overline - like underline, but the line is over the text. | |
1015 | ;; shadow - text will have a shadow. | |
1016 | ;; box - text will be surrounded by a box. | |
a18ed129 | 1017 | ;; outline - print characters as hollow outlines. |
87a16a06 | 1018 | ;; |
06fb6aab | 1019 | ;; See the documentation for `ps-extend-face'. |
87a16a06 | 1020 | ;; |
bc0d41bd KH |
1021 | ;; Let's, for example, remap `font-lock-keyword-face' to another foreground |
1022 | ;; color and bold attribute: | |
87a16a06 | 1023 | ;; |

87a16a06 | 1025 | ;; |
6c8f2753 RS |
1026 | ;; If you want to use a new face, define it first with `defface', |
1027 | ;; and then call `ps-extend-face' to specify how to print it. | |

1029 | ;; |
1030 | ;; How Ps-Print Has A Text And/Or Image On Background | |
1031 | ;; -------------------------------------------------- | |
1032 | ;; | |
d3ab8dac | 1033 | ;; ps-print can print texts and/or EPS PostScript images on background; it is |
87a16a06 RS |
1034 | ;; possible to define the following text attributes: font name, font size, |
1035 | ;; initial position, angle, gray scale and pages to print. | |
1036 | ;; | |
1037 | ;; It has the following EPS PostScript images attributes: file name containing | |
1038 | ;; the image, initial position, X and Y scales, angle and pages to print. | |
1039 | ;; | |
1040 | ;; See documentation for `ps-print-background-text' and | |
1041 | ;; `ps-print-background-image'. | |
1042 | ;; | |
1043 | ;; For example, if we wish to print text "preliminary" on all pages and text | |
1044 | ;; "special" on page 5 and from page 11 to page 17, we could specify: | |
1045 | ;; | |
1046 | ;; (setq ps-print-background-text | |
1047 | ;; '(("preliminary") | |
1048 | ;; ("special" | |

87a16a06 RS |
1053 | ;; 5 (11 . 17)) ; page list |
1054 | ;; )) | |
1055 | ;; | |
1056 | ;; Similarly, we could print image "~/images/EPS-image1.ps" on all pages and | |
1057 | ;; image "~/images/EPS-image2.ps" on page 5 and from page 11 to page 17, we | |
1058 | ;; specify: | |
1059 | ;; | |
1060 | ;; (setq ps-print-background-image | |
1061 | ;; '(("~/images/EPS-image1.ps" | |
1062 | ;; "LeftMargin" "BottomMargin") ; X and Y position (lower left corner) | |
1063 | ;; ("~/images/EPS-image2.ps" | |
1064 | ;; "LeftMargin" "BottomMargin PrintHeight 2 div add" ; X and Y position | |

1066 | ;; nil nil nil | |
1067 | ;; 5 (11 . 17)) ; page list | |
1068 | ;; )) | |
1069 | ;; | |
1070 | ;; If it is not possible to read (or does not exist) an image file, that file | |
1071 | ;; is ignored. | |
1072 | ;; | |

6e1b1da6 GM |
1075 | ;; 1. Print background color |
1076 | ;; 2. Print zebra stripes | |
1077 | ;; 3. Print background texts that it should be on all pages | |
