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?

Bitmap means exactly which Format? If you refer to BMP, IT does not support an alpha channel, so no transparency in the picture itself. Am 12.01.2015 19:25 schrieb "Letizia Galli" :

Not sure if it helps you, but the Juicy Pixels library can load many different formats, including TIFF: https://hackage.haskell.org/package/JuicyPixels Can you show your code that causes trouble? Regards, Marcin

Hi Marcin, Thank you for your reply I'll look into it. I would like to show you the code but I have to ask as we like to keep it confidential at the moment. Best, Letizia 2015-01-12 23:37 GMT+01:00 Marcin Mrotek :

Hi thank you for your reply, yes I mean BMP and I know it doesn't have a alpha channel I was just asking if there is a way to use images in a format with a transparent background. Best Letizia 2015-01-12 19:57 GMT+01:00 Norbert Melzer :
