The image's selected colors do not convert
- Question
When adding an image to a worksheet, I extracted all unique colors, then graphed the list. Everything good so far, but when I select 'vectors' and choose an ICC profile, the graph displays nothing. Is this a bug, or am I misunderstanding something?
- Answer
This issue stems from how the Worksheet handles conversions. When a profile is added to an image with selected colors, only the image data is converted by the profile. The selected color list is left alone.
For what you are trying to do, the solution is easy. After making your selected colors list, choose "Use as Primary Data Source" in the 1st column's color list PRIOR to applying profiles or graphing, and the color numbers will be converted correctly.
