             Summary: ImageWorker writePNG forces component color model for images that can be encoded as-is
                 Key: GEOT-3991
                 URL: https://jira.codehaus.org/browse/GEOT-3991
             Project: GeoTools
          Issue Type: Improvement
            Reporter: Andrea Aime
            Assignee: Andrea Aime
             Fix For: 2.7.5


If the output is not required to be paletted, but the image is, the png encode forces a component color model, however this is not necessary, png can encode all sorts of images in IndexColorModel (with per entry alpha, and with large palettes too)
