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.
Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
