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 normal size, some detail is lost in the compression.

This class writes JFIF compliant JPEG files. LOSSY_QUALITY can be set for JPEG images. Writes both 24 bit color and 8 bit gray-scale images and has support for progressive encoding. Grayscale palettes need not be ordered to be recognized, although Red Green and Blue palette indexes for a single palette entry must be equivalent in order for the image to be saved using 8 bit compression.
