UNI2ANIMGIF
a tool for transforming UNIPEN files to animated gifs

SYNOPSIS

uni2animgif unipen-file [unipen-files] [options] [output.gif]

DESCRIPTION

Using the tool uni2animgif, segments can be selected from a number of UNIPEN files. Each segment is stored as an animated gif in the output file. The code for reading and writing gifs stams from Rene K. Mueller's and Marc Podlipec's gifmerge. Uni2animgif recognizes command-line arguments and reads a resource file unipen.def. When starting uni2animgif, two environment variables have to be set, as described in general environment settings.

Furthermore, the environment variable UNIPEN2ANIMGIF_PATH has to be set. This variable contains the directory in which the individual gif files are contained used by uni2animgif. In particular, the directory must contain a background gif, and two other gifs, one for pen-down and one for pen-up samples.
