+

+
| + |
+ Pal2rgb 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. + |
+
| + |
+ Options that affect the interpretation of input data +are: + |
+
| + |
+
+ −C + |
++ |
+
+ This option overrides the default behavior of +pal2rgb in determining 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 +−C option can be used to explicitly specify the +number of bits for colormap entries: −C 8 for +8-bit values, −C 16 for 16-bit values. + |
++ | +
| + |
+ Options that affect the output file format are: + |
+
| + |
+
+ −p + |
++ |
+
+ Explicitly select the planar configuration used in +organizing data samples in the output image: −p +contig for samples packed contiguously, and −p +separate for samples stored separately. By default +samples are packed. + |
++ | +
| + |
+
+ −c + |
++ |
+
+ Use the specific compression algorithm to encoded image +data in the output file: −c packbits for +Macintosh Packbits, −c lzw for Lempel-Ziv & +Welch, −c zip for Deflate, −c none +for no compression. If no compression-related option is +specified, the input file’s compression algorithm is +used. + |
++ | +
| + |
+
+ −r + |
++ |
+
+ Explicitly specify the number of rows in each strip of +the output file. If the −r option is not +specified, a number is selected such that each output strip +has approximately 8 kilobytes of data in it. + |
++ | +
| + |
+ Only 8-bit images are handled. + |
