------- Additional Comments From [EMAIL PROTECTED] 2005-12-07 20:15 ------- Here are some details I found after digging into it: This is a feature in SpamProbe being tried out in the experimental 1.3x2 release of SpamProbe as announced at http://sourceforge.net/mailarchive/message.php?msg_id=14058893 Google didn't find any detailed discussion of the feature. The source code (file src/parser/GifParser.cc from the 1.3x2 source tarball) appears to use libungif to extract the following information from embedded GIF files in an email and generate tokens from them for the Bayesian filter. I don't see anything to handle jpeg images right now: MD5 digest of the image (I think digest of the image bytes from the message, not parsed or uncompressed to pixels, but I'm not sure) height, width, left , top, interlaced or not, color map or no color map, bits per pixel, the red green and blue values inthe color map if there is one, and the extension code and characters of any GIF extension records. The "image number" is made part of the tokens in the above paragraph (not the MD5) where I think that may have to do with multiple images in a single GIF object. ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
