20 | # This little script uses convert from ImageMagick to generate CUPS buttons. | |
21 | # It requires ImageMagick version 6.2.4 or higher. | |
22 | # | |
23 | # It can generate 20-pixel high one-line buttons and 40-pixel high two-line | |
24 | # buttons. | |
25 | # | |
26 | # Usage: | |
27 | # | |
28 | # tools/makebuttons [--font filename] locale buttons.txt | |
29 | # | |
30 | # "Locale" is the locale name, either "ll" or "ll_CC" where "ll" is the | |
31 | # 2-letter language abbreviation and "CC" is the 2-letter ISO country | |
32 | # code. The new "ll-region" syntax is *not* supported at this time | |
33 | # and should not be used! | |
34 | # | |
35 | # "Buttons.txt" is a file containing the buttons to be created and must | |
36 | # be formatted as follows: | |
37 | # | |
38 | # filename.gif color text for button | |
39 | # | |
40 | # "filename.gif" is the name of the image file to create. | |
41 | # | |
42 | # "color" is the color of the button, one of "std" (the normal olive | |
43 | # background), "black", "green", or "red". | |
44 | # | |
45 | # The remainder of the line following the color is used as the text | |
46 | # for the button. Use "@UP" and "@DOWN" to include up and down arrows, | |
47 | # and "\\n" to break the text into 2 lines (not generally recommended). | |
48 | # | |
49 | # Lines starting with '#' are treated as comments. See the file | |
50 | # "tools/buttons.txt" for inspiration... | |
