pal2rgb \- convert
a palette color TIFF image to a full color image

.SH "DESCRIPTION"
.PP
\fBpal2rgb\fR converts a palette color TIFF image to a full
color image by applying the colormap of the palette image to each sample to
generate a full color RGB image\&.
.SH "OPTIONS"
.SS "Input Data Options"
.PP
The following input data options are supported:
.sp
.ne 2
.mk
\fB-\fBC\fR\fR
.in +16n
.rt
Override the
default behavior of \fBpal2rgb\fR to determine whether or not colormap
entries contain 16-bit or 8-bit values\&. By default, the colormap is inspected
and if no colormap entry greater than 255 is found, the colormap is assumed
to have only 8-bit values\&. Otherwise, 16-bit values, as required by the TIFF
specification, are assumed\&. The -\fBC\fR option can be used to explicitly
specify the number of bits for colormap entries: -\fBC 8\fR for
8-bit values, -\fBC 16\fR for 16-bit values\&.
