Comments
Only Point and Stamp objects that are using a bitmap can be set to use a transparent color. By default the transparent color is white (0x00FFFFFF). In order for the transparent bitmaps to be painted properly the LTEFXu.dll needs to be present for WIN32. If the appropriate DLL is not present, the transparent bitmap stamps will be painted as non-transparent bitmap stamps.
The next stamp created will be transparent.
