  25 .TH GIF2TIFF 1 "November 2, 2005" "libtiff"
  26 .SH NAME
  27 gif2tiff \- create a
  28 .SM TIFF
  29 file from a GIF87 format image file
  30 .SH SYNOPSIS
  31 .B gif2tiff
  32 [
  33 .I options
  34 ]
  35 .I input.gif
  36 .I output.tif
  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.
