I need to have a 1bit color mask in my app, I made a 1 color png in photoshop
but I receive an error from python saying that the my image is not a valid mask.

I even tried to download the mask in this example
http://wiki.forum.nokia.com/index.ph...vas_with_masks
but it gives me the same error

I'm using a n95

do you know what I need to do to create a valid mask?

Thanks

Giuseppe
