The snippet works on my iphone, but then in the simulator it doesn't work. I get something like : CGBitmapContextCreate: unsupported parameter combination: 8 integer bits/component; 24 bits/pixel; 3-component color space; kCGImageAlphaNone; 1440 bytes/row.

I noticed that for the same troubled image, on the device CGImageGetBytesPerRow(imageRef) == 1920 and width*4 == 1920, but in the simulator CGImageGetBytesPerRow(imageRef) == 1440.

I then tried what steipete suggested and it works on both the device and simulator. Thoughts?
