Gif image file format

Note 6/13/2001 - there is a bug in the GIF writer - sometimes the file is not readable (either by Lispix or Photoshop).  I don't see any pattern. Use with caution.  Available here:  File / File Utilities Tool/ gif / save as gif .

 

Permission to write GIF files.

(Lispix is public domain and distributed for free.  Lispix has the capability to write GIF files for convenience and compatability with other software.  The GIF files that Lispix writes are by no means the most compact - they use the full 256 color palette.)
