Uncompressing the file doesn't restore any damage done in compression, but you *can't* view the compressed file -- your monitor won't display it, you *have to* uncompress the file into a simple RGB bitmap before your hardware can display it to you. -- David Dyer-Bennet, <mailto:dd-b@xxxxxxxx>, <http://www.dd-b.net/dd-b/> RKBA: <http://noguns-nomoney.com/> <http://www.dd-b.net/carry/> Pics: <http://dd-b.lighthunters.net/> <http://www.dd-b.net/dd-b/SnapshotAlbum/> Dragaera/Steven Brust: <http://dragaera.info/>
