SOF - Start Of Frame marker which is a two byte hexadecimal code, FFCx where x is a value from 0 to 3. The frame marker indicates the dimensions of the image (height and width). See JNG (JPEG Network Graphics) Format Version 1.0 http://www.libpng.org/pub/mng/spec/jng.html Reading JPEG image dimensions http://mini.net/tcl/757.html Probably a sleight "glitch" in the image file that LView has problems with and IrfanView does not. -- Gerry Boyd ============= PCWorks Mailing List ================= Don't see your post?
