JPEG is a popular lossy image data format for compressed raster data.

This format is supported by the ImageTools[Read] and ImageTools[Write] commands. The general-purpose commands Import and Export also support this format.

An image may be specified as the background of a plot with the image option (see plot,options).

The context-sensitive menu can be used to export Maple plot graphics to JPEG format.

Additionally, JPEG images can be inserted directly into a Maple Document.
