| gif2tiff - create a TIFF file from a GIF87 format image file |
| gif2tiff [ options ] input.gif output.tif |
| Gif2tiff converts a file in the GIF87 format to TIFF. The TIFF image is created as a palette image, with samples compressed with the Lempel-Ziv & Welch algorithm (Compression=5). These characteristics can overriden, or explicitly specified with the options described below. |
| -c |
| Specify a compression scheme to use when writing image data: -c none for no compression, -c packbits for the PackBits compression algorithm, -c zip for the Deflate compression algorithm, and -c lzw for Lempel-Ziv & Welch (the default). |
| -r |
| 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. |
| The program is based on Paul Haeberli's fromgif program which, in turn, is based on Marcel J.E. Mol's GIF reader. |
| Should have more options to control output format. |
