My app allows upload of an image from the camera roll. Some images are causing the app to crash when I attempt to save them to my documents directory prior to upload. I'm converting the image to a PNG prior to saving, but that hasn't helped. Here's the error...
Tue Aug 31 20:39:13 localhost XXX[76409] <Error>: CGBitmapContextCreate: unsupported parameter combination: 8 integer bits/component; 32 bits/pixel; 3-component color space; kCGImageAlphaLast; 1600 bytes/row.

and here's a sample of my code...
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *img = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
NSData *pngData = UIImagePNGRepresentation(img);
UIImage *pngImg = [UIImage imageWithData:pngData];
... code to save image ...
}
