What are the RGB values of the transparency color?

Thanks!

Found it!

Any pixel whose RGB color is (255,128,255), a light pink, will be treated as transparent for 4-bit and 8-bit icons.

Wait. This does not appear to work with graphical buttons?

I want to create a triangular graphical button. The 255,128,255 seems to work with bitmaps but not graphical buttons?

Thanks

Chris,

Guessing off the top of my head... maybe you could use a gadget rather than a button. Draw the bitmap in the gadget's ondraw handler and react to the taps in the onpenup handler.

Good luck,
Frank

I think this does not work for any bitmap of any kind. I try to place different bitmaps on screen (cards on a board), and pixels with (255,128,255) are definitively not treated as transparency colors.

Does someone knows a way to have transparent pixels in a bitmap ?
