Here is what I did (WindowsXP, Rev 3.0):
- Chose the "pentagon" shape and put text on it
- resized the height
-exported to "Pentagon"
- resized the same shape again - without "reset" in between
-exported to "Pentagon2"
- now reset everything
- chose the "pentagon" shape again
- resized the shape
- exported to "PentagonAfterReset"
Result: re-Imported "Pentagon", "Pentagon2", and "PentagonAfterReset".
All images - which have a solid white background (as have the shapes
from which one can choose) - show the expected transparency, i.e. not
only a white border.
Is it possible that your shapes originally had a different color than white?
In any case, if you have problems here, they indeed could be related to
the effects I had described in my last post and to the special
Revolution image format that I had named to be "pre-PNG".
