6 gifecho - generate a GIF from ASCII text
7
9 gifecho [-v] [-s colormap-size] [-f foreground] [-c R G B] [-t text]
10 [-h] [gif-file]
11
13 A program to generate GIF images out of regular text. Text can be one
14 line or multi-line, and is converted using 8 by 8 fixed font.
15 This program reads stdin if no text is provided on the command line
17 (-t), and will dump the created GIF file to stdout.
18
20 -v
21 Verbose mode (show progress). Enables printout of running scan
22 lines.
23 -s colormap-size
25 Explicitly defines the size of the color map of the resulting gif
26 image. Usually the image will be bicolor with fg as color 1, unless
27 [-f] is explicitly given in case the color map size will be big
28 enough to hold it. However it is sometimes convenient to set the
29 color map size to certain size while the fg color is small mainly
30 so this image may be merged with another (images must match color
31 map size).
32 -f foreground
34 Select foreground index (background is always 0). By default it is
35 one and therefore the image result is bicolored. if FG is set to n
36 then color map will be created with 2^k entries where 2^k > n for
37 minimum k, assuming k <= 8. This color map will be all zeros except
38 this foreground index. This option is useful if this text image
39 should be integrated into other image colormap using their colors.
40 -c R G B
42 The color to use as the foreground color. White by default.
43 -t text
45 One line of text can be provided on the command line. Note you must
46 encapsulate the Text within quotes if it has spaces (The quotes
47 themselves are not treated as part of the text). If no -t option is
48 provided, stdin is read until end of file.
49 -h
51 Print one line command line help, similar to Usage above.
52
54 There is a hardcoded limit of 100 the number of lines.
