  26 .TH GIF2TIFF 1 "November 2, 2005" "libtiff"
  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.
