Summary0003114: Opacity values in colormap are not copied
Description

When duplicating the current colormap in the color module then the color values appear correctly in the duplicated colormap, but all the opacity values are set to 1.0. This is very confusing for users, who just see that their background volume disappears when they select their custom colormap for their empty labelmap volume.

How to reproduce:

  • Load MRHead sample
  • Go to Colors module and duplicate the current (GenericColors) colormap
  • Go to editor, select the new UserGenerated/GenericColorsCopy labelmap
  • The MRHead image disappears from the screen
    => ERROR: the user doesn't understand what happened and what to do now!

Workaround:

  • Go to colors module, set color #0 opacity to 0.0
    => the MRhead image appears

Yes, it seems that the opacity is not copied from the source color node.

Fixed in svn 21988[1].
The color logic CopyNode method was using the color node copy method that just copied the name and rgb, switched it to use the one that also copies opacity.
Added testing as well.

Details Diff 		BUG: copy opacity when creating a copy of a color node

The MRML color logic was using the the color node copy
method that just copied the name and rgb, switched it
to use the one that also copies opacity.
Expanded the testing to exercise the copy and test the
results.
