[field #13]                  Summary: Correct color conversions
[field #14]      Original Submission: Until now the emphasis has been mainly on grayscale images since FITS images were the primary input. Using simple channel data colors do work fine, however there is still a lot of work that needs to be done to have color images as input.

For example when converting a JPEG image to PDF, the colors are not displayed correctly. Another example is when you ask to only fill the black channel of CMYK in PDF format, the inversion has to be the opposite.
