Description Michael Vrhel 2008-05-21 14:27:47 UTC
With the attached example and custom color callback enabled the classification
of the image is dependent upon if high level images occurs.  If it does occur,
the image is incorrectly labeled as an object fill and is colored blue, when
custom color callback is enabled.  If high level images does not occur, the
image is correctly labeled as an image type and colored green, when custom color
callback is enabled.  To see this use two different resolutions.

e.g.

High level images enabled.  Image object rendered as fill type.
-sDEVICE=tiff32nc -dBufferSpace=100000000 -o test.tif -r600  -c "<<
/CustomColorCallback 128 string .pantonecallback >> setsystemparams" -f

No high level images.  Image object rendered as image type.
-sDEVICE=tiff32nc -dBufferSpace=100000000 -o test.tif -r100  -c "<<
/CustomColorCallback 128 string .pantonecallback >> setsystemparams" -f

A simple 8 bit device dependent RGB image.

This has been fixed with the changes that we have done to object tagging.
