26 | .SH NAME | |
27 | gif2tiff \- create a | |
28 | .SM TIFF | |
29 | file from a GIF87 format image file | |
30 | .SH SYNOPSIS | |
31 | .B gif2tiff | |

37 | .SH DESCRIPTION | |
38 | .I Gif2tiff | |
39 | converts a file in the GIF87 format to | |
40 | .SM TIFF. | |
41 | The | |
42 | .SM TIFF | |
43 | image is created as a palette image, with samples | |
44 | compressed with the Lempel-Ziv & Welch algorithm (\c | |
45 | .IR Compression =5). | |
46 | These characteristics can overridden, or explicitly specified | |
47 | with the options described below. | |
48 | .SH OPTIONS | |
49 | .TP | |
50 | .B \-c | |
51 | Specify a compression scheme to use when writing image data: | |
52 | .B "\-c none" | |
53 | for no compression, | |
54 | .B "\-c packbits" | |
55 | for the PackBits compression algorithm, | |
56 | .B "\-c zip" | |
57 | for the Deflate compression algorithm, | |
58 | and | |
59 | .B "\-c lzw" | |
60 | for Lempel-Ziv & Welch (the default). | |
61 | .TP | |
62 | .B \-r | |
63 | Write data with a specified number of rows per strip; | |
64 | by default the number of rows/strip is selected so that each strip | |
65 | is approximately 8 kilobytes. | |
66 | .SH NOTES | |
67 | The program is based on Paul Haeberli's | |
68 | .I fromgif | |
69 | program which, in turn, is based on Marcel J.E. Mol's GIF reader. | |
70 | .SH BUGS | |
71 | Should have more options to control output format. | |
