Saving a PNG (or good quality JPG) image to the Photos Library.

Question

Scenario Saving a 320x480 view as an image in the user's saved photos album.

Problem Always saves a 800x?, low quality JPG.

Using the normal renderInContext/UIImageWriteToSavedPhotosAlbum method to save a view to the library. I've tried converting the UIImage to a PNGRepresentation then using that data to make a new UIImage - it still just saves a JPG in the library.

I could possibly solve this problem by upsizing my view to 800px tall then take the "screenshot" - but that's going to be a lot of work.

Has anyone been able to solve this low-quality saved image problem? I've seen threads all over about it but the always die off without any solid ideas.

Thanks, Ian
