These characteristics can overriden, or explicitly specified with the options described below. <P> Any colormap information in the rasterfile is carried over to the <FONT SIZE="-1">TIFF</FONT> file by including a <I>Colormap</I> tag in the output file. If the rasterfile has a colormap, the <I>PhotometricInterpretation</I> tag is set to 3 (palette); otherwise it is set to 2 (RGB) if the depth is 24 or 1 (min-is-black) if the depth is not 24. <A NAME="lbAE"> </A> <H2>OPTIONS</H2> <DL COMPACT> <DT><B>-c</B> <DD> Specify a compression scheme to use when writing image data: <B>-c none</B> for no compression, <B>-c packbits</B> for the PackBits compression algorithm, <B>-c jpeg</B> for the baseline JPEG compression algorithm, <B>-c zip</B> for the Deflate compression algorithm, and <B>-c lzw</B> for Lempel-Ziv & Welch (the default). <DT><B>-r</B> <DD> Write data with a specified number of rows per strip; by default the number of rows/strip is selected so that each strip is approximately 8 kilobytes. </DL> <A NAME="lbAF"> </A> <H2>BUGS</H2> Does not handle all possible rasterfiles.
