[ XITE Reference Manual | XITE home ]
Name
color2ascii - dump a colortable in ascii format
Syntax
color2ascii [<option>...] <image-file> <ascii-file>
Description
Writes the colortable contents to ascii-file, in ascii
format. Use "-" or "-1" for output to stdout.
The ascii output can be given as input to mct(1).
For details on the output format, refer to
PrintColortable(3).
On a visual with composite colormaps (DirectColor or
TrueColor visual), one part of the pixelvalue is used as an
index into the colormap which controls the amount of red, one
part is used as an index into the green colormap and one part
for the blue colormap.
On a visual with non-composite colormap (e.g. PseudoColor
visual), only one of these parts is used as an index into the
single colormap.
When the contents of a colortable stored in a file in BIFF
format is printed, only the PseudoColor part of
the pixelvalue is shown because the file only stores this
part of the pixel-value.
Options
-
-hex
- Print pixel value as hexademical number (default decimal)
