Short for Joint Photographic Experts Group. JPEG is a lossy compression technique for color images. Although it can reduce files sizes to about 5% of their uncompressed size, some detail is lost in the compression.

Supports reading JFIF compliant files. The LOSSY_QUALITY value can only be approximated when reading JPEG images and may differ slightly from the value specified when compressing the image. Reads both 8 and 24 bit images. Progressive JPG images are supported as well.
