We tested your new release and we found another fault.

I try explain to you what we do.

1) Cut out part of bitmap.

2) Paste this cut out to other place.

3) Insert new annotation (any).

4) Combine all annotations with background.

After that drawing is damaged.

ORIGINAL



RESULT after combining

There is a bug on copy/cut to clipboard and will be fixed in next minor release. Unfortunately copy/cut functions copied also an non-existent alpha channel that is copied back "on paste".
CopyObjectsToBack with native pixel format (last parameter = true) doesn't work with images having alpha channel, and this is the reason of the problem.

A workaround is to execute:

ImageEnVect1.RemoveAlphaChannel();
just before CopyObjectsToBack.

Or call CopyObjectsToBack with second parameter = false (MergeAlphaChannel):

ImageEnVect1.CopyObjectsToBack(true, false, false);

Hope this helps.
