NAME¶
gif2rgb - convert images saved as GIF to 24-bit RGB triplets
SYNOPSIS¶
gif2rgb [-v] [-1] [-c colors] [-s width height] [-o outfile] [-h] [gif-file]
OPTIONS¶
-v
Verbose mode (show progress). Enables printout of running
scan lines.
-1
Only one file in the format of RGBRGB... triplets (Each
of R, G,B is a byte) is being read or written. This file size is 3 * Width *
Height. If stdin is used for input or stdout for output, this option is
implicitly applied. The default (if not `-1') is 3 files with the names
OutFileName.R, OutFileName.G, OutFileName.B, each of which is Width * Height
bytes.
-c colors
Specifies number of colors to use in RGB-to-GIF
conversions, in bits per pixels, so '-c 8' actually specifies 256 colors
(maximum and default).
-s width height
Sets RGB-to-GIF conversion mode and specifies the size of
the image to read.
-o
specifies the name of the out file (see also `-1'
above).
-h
Print one line of command line help, similar to Usage
above.
By default, convert a GIF input file to RGB triplets. If -s is specified, convert RGB input to a GIF.
If no input file is given, gif2rgb will try to read data from stdin.
BUGS¶
Feeding this utility a GIF with an invalid colormap, or other kinds of malformations, index will produce invalid output and may core-dump the tool. Don't do that.
