[Geoserver-devel] [jira] Created: (GEOS-431) GIF - improvments

GIF - improvments
------------------

         Key: GEOS-431
         URL: http://jira.codehaus.org/browse/GEOS-431
     Project: GeoServer
        Type: Improvement
Reporter: dblasby
Assigned to: dblasby
     Fix For: 1.3.0 RC5

Basically, have better transparency processing.

ignore this (my notes):

    + ignore trasparancy at beginning
     + go as normal (255 max colours), then make compressed colour map, and conversion table (old colour->new colour)
     + re-index pixels, using conversion table (quick), and also do the transparency
     + dont re-count the number of colours used.
     
     + gif support is pretty good, and faster. But only sampling every-other-pixel.
     + the only "todo" is the fact that the colour reducer always produces 255 colours, even if there's less in
       the picture. This isnt really a problem, but it does waste a little space.
