SEUIXP Classes and the Ribbon Manager supports 32 Bit Bitmaps with alpha channel.

 

All Windows versions older than 'Windows XP' do not support Bitmaps with alpha channel.

All version since 'Windows XP' can display 32 Bit bitmaps with alpha channel. If you want optimal looking toolbars for all os versions

and all color modes of graphic cards, you can use separate bitmaps for 4, 8, 24 and 32 Bit modes.

With the function SEGetMaxColorBits() you get the maximum color depth in bits. (8 = 256 Colors for example), which your current system supports.
