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
