Bitmap means exactly which Format? If you refer to BMP, IT does not support an alpha channel, so no transparency in the picture itself.

Hi :-)
I have just joined and I don't know if this is a beginner question,
anyway I have been given an Haskell code which uses images,
but when I convert a tiff with transparent background into a bitmap, their background becomes 
white and I need it to be transparent.
Is there a way in Haskel to convert a bitmap with solid background into a bitmap with transparent
background?
Is there another format that can be used instead of bitmap in Haskell?
Best,
Letizia
