Remarks

Joint Photographics Experts Group (JPEG) format bitmaps support frame level thumbnails and frame level metadata. They do not support preview, global thumbnails, global metadata, or multiple frames.

Encoding does not work in partial trust. See WPF Partial Trust Security for information on partial trust.
