- // Returns an image resized to |targetSize|.
- //
- // If |preserveAspectRatio| is YES, the original image aspect ratio is
- // preserved.
- //
- // When |preserveAspectRatio| is YES and if |targetSize|'s aspect ratio
- // is different from the image, the resulting image will be shrunken to
- // a size that is within |targetSize|.
- //
- // To preserve the |targetSize| when |preserveAspectRatio| is YES, set
- // |trimToFit| to YES. The resulting image will be the largest proportion
- // of the receiver that fits in the targetSize, aligned to center of the image.
- //
- // Image interpolation level for resizing is set to kCGInterpolationDefault.

- // Returns an image rotated by |orientation| where the current orientation is

- // Supplying UIImageOrientationUp to |orientation| will return a copy of the
