| 27 | .SH NAME | |
| 28 | gif2tiff \- create a | |
| 29 | .SM TIFF | |
| 30 | file from a GIF87 format image file | |
| 31 | .SH SYNOPSIS | |
| 32 | .B gif2tiff | |
| 33 | [ | |
| 34 | .I options | |
| 35 | ] | |
| 36 | .I input.gif | |
| 37 | .I output.tif | |
| 38 | .SH DESCRIPTION | |
| 39 | .I Gif2tiff | |
| 40 | converts a file in the GIF87 format to | |
| 41 | .SM TIFF. | |
| 42 | The | |
| 43 | .SM TIFF | |
| 44 | image is created as a palette image, with samples | |
| 45 | compressed with the Lempel-Ziv & Welch algorithm (\c | |
| 46 | .IR Compression =5). | |
| 47 | These characteristics can overridden, or explicitly specified | |
| 48 | with the options described below. | |
| 49 | .SH OPTIONS | |
| 50 | .TP | |
| 51 | .B \-c | |
| 52 | Specify a compression scheme to use when writing image data: | |
| 53 | .B "\-c none" | |
| 54 | for no compression, | |
| 55 | .B "-c packbits" | |
| 56 | for the PackBits compression algorithm, | |
| 57 | .B "-c zip" | |
| 58 | for the Deflate compression algorithm, | |
| 59 | and | |
| 60 | .B "\-c lzw" | |
| 61 | for Lempel-Ziv & Welch (the default). | |
| 62 | .TP | |
| 63 | .B \-r | |
| 64 | Write data with a specified number of rows per strip; | |
| 65 | by default the number of rows/strip is selected so that each strip | |
| 66 | is approximately 8 kilobytes. | |
| 67 | .SH NOTES | |
| 68 | The program is based on Paul Haeberli's | |
| 69 | .I fromgif | |
| 70 | program which, in turn, is based on Marcel J.E. Mol's GIF reader. | |
| 71 | .SH BUGS | |
| 72 | Should have more options to control output format. | |
