Pal2rgb converts a palette color

Packit |
994f1a |
<small>TIFF</small> image to a full color image by applying
|
|
Packit |
994f1a |
the colormap of the palette image to each sample to generate

Packit |
994f1a |
a full color <small>RGB</small> image.

This option overrides the default behavior of
|
|
Packit |
994f1a |
pal2rgb in determining whether or not colormap
|
|
Packit |
994f1a |
entries contain 16-bit or 8-bit values. By default the
|
|
Packit |
994f1a |
colormap is inspected and if no colormap entry greater than
|
|
Packit |
994f1a |
255 is found, the colormap is assumed to have only 8-bit
|
|
Packit |
994f1a |
values; otherwise 16-bit values (as required by the
|
|
Packit |
994f1a |
<small>TIFF</small> specification) are assumed. The
|
|
Packit |
994f1a |
−C option can be used to explicitly specify the
|
|
Packit |
994f1a |
number of bits for colormap entries: −C 8 for
|
|
Packit |
994f1a |
8-bit values, −C 16 for 16-bit values.
