I’m learning to use sketchbook pro on my iPad2 mainly for altering pictures that I saved from the internet.
When I download a picture of decent resolution it sometimes has no border. Then after doing my alterations I save it and export it to my camera roll but it has a thick white border around it. It also looks about 40% smaller (although I don’t know if that’s just representation rather than being actually smaller.
How do I save the picture so I don’t have to then go and crop the border off as when I load it into keynote it does have the unwanted white border?

On a related note, i’m currently using a different app; ‘Snapseed’ to crop images (although now i can crop in the pic gallery in iOS5) Is there a crop option in sketchbook pro for iPad?
