|
A program to generate GIF images out of regular text. Text can be one line
|
|
or multi-line, and is converted using 8 by 8 fixed font.<P>
|
|
|
|
<H1>Usage:</H1>
|
|
|
|
<pre>
|
|
text2gif [-q] [-s ClrMapSize] [-f FGClr] [-c R G B] [-t "Text"] [-h]
|
|
</pre>
|
|
|
|
This program reads stdin if no text is provided on the command line (-t),
|
|
and will dump the created GIF file to stdout.<P>
|
|
|
|
<H1>Memory required:</H1>
|
|
|
|
Line.
|
|
|
|
<H1>Options:</H1>
|
|
|
|
<DT> [-q]
|
|
<DD> Quiet mode. Defaults off on MSDOS, on under UNIX. Controls printout
|
|
of running scan lines. Use -q- to invert.<P>
|
|
|
|
<DT>[-s ClrMapSize]
|
|
<DD>Explicitly defines the size of the color map of the
|
|
resulting gif image. Usually the image will be bicolor with fg as color
|
|
1, unless [-f] is explicitly given in case the color map size will be
|
|
big enough to hold it. However it is sometimes convenient to set the
|
|
color map size to certain size while the fg color is small mainly so
|
|
this image may be merged with another (images must match color map size).<P>
|
|
|
|
<DT>[-f FG]
|
|
<DD> Select foreground index (background is always 0). By default
|
|
it is one and therefore the image result is bicolored.
|
|
if FG is set to n then color map will be created with 2^k entries where
|
|
2^k > n for minimum k, assuming k <= 8. This color map will be all zeros
|
|
except this forground index. This option is useful if this text image
|
|
should be integrated into other image colormap using their colors.<P>
|
|
|
|
<DT> [-c R G B]
|
|
<DD> The color to use as the foreground color. White by default.<P>
|
|
|
|
<DT> [-t "Text"]
|
|
<DD> One line of text can be provided on the command
|
|
line. Note you must encapsulate the Text within quotes if it has spaces
|
|
(The quotes themselves are not treated as part of the text). If no -t
|
|
option is provided, stdin is read until end of file.<P>
|
|
|
|
<DT> [-h]
|
|
<DD> Print one line command line help, similar to Usage above.<P>
|
|
|
|
<H1>Notes:</H1>
|
|
|
|
There is a hardcoded limit of 100 the number of lines.<P>
