If you have to handle different formats then it's going to be a pain. You'll have to be able to understand the different formats and be able to read/write/transform them, probably through streams. On a regular PC I'd say to look at ImageMagick which has very large image support. I searched for an Android port and came up with this. It might be worth a try. It looks unfinished though, so you'd probably have to do some work for better format coverage.
