UIImagePickerController editing allowed locks UIImage to max size of 320x320

Question

Update:

With iPhone OS 3.0+, the whole UIImagePickerController API has changed. This question and answer should be considered 2.2. legacy code.

Answer 1

I must be too late to answer this question, but I have got a better way to get this job done.

static inline double radians (double degrees) {return degrees * M_PI/180;}

+(UIImage*)editedImageFromMediaWithInfo:(NSDictionary*)info{
    if(![info   objectForKey:UIImagePickerControllerCropRect])return nil;
    if(![info   objectForKey:UIImagePickerControllerOriginalImage])return nil;

    UIImage *originalImage=[info objectForKey:UIImagePickerControllerOriginalImage];
    CGRect rect=[[info objectForKey:UIImagePickerControllerCropRect] CGRectValue];

    CGImageRef imageRef = CGImageCreateWithImageInRect([originalImage CGImage], rect);

    CGBitmapInfo bitmapInfo = CGImageGetBitmapInfo(imageRef);
    CGColorSpaceRef colorSpaceInfo = CGImageGetColorSpace(imageRef);
    CGContextRef bitmap = CGBitmapContextCreate(NULL, rect.size.width, rect.size.height, CGImageGetBitsPerComponent(imageRef), CGImageGetBytesPerRow(imageRef), colorSpaceInfo, bitmapInfo);

    if (originalImage.imageOrientation == UIImageOrientationLeft) {
        CGContextRotateCTM (bitmap, radians(90));
        CGContextTranslateCTM (bitmap, 0, -rect.size.height);

    } else if (originalImage.imageOrientation == UIImageOrientationRight) {
        CGContextRotateCTM (bitmap, radians(-90));
        CGContextTranslateCTM (bitmap, -rect.size.width, 0);

    } else if (originalImage.imageOrientation == UIImageOrientationUp) {
        // NOTHING
    } else if (originalImage.imageOrientation == UIImageOrientationDown) {
        CGContextTranslateCTM (bitmap, rect.size.width, rect.size.height);
        CGContextRotateCTM (bitmap, radians(-180.));
    }

    CGContextDrawImage(bitmap, CGRectMake(0, 0, rect.size.width, rect.size.height), imageRef);
    CGImageRef ref = CGBitmapContextCreateImage(bitmap);

    UIImage *resultImage=[UIImage imageWithCGImage:ref];
    CGImageRelease(imageRef);
    CGContextRelease(bitmap);
    CGImageRelease(ref);

    return resultImage;
}

It only crops the original image with the relative CropRect, although this method dosen't scale the image, but it is short and sweet for me. Just for reference :)
