Do have any idea how compressed that file would get if you rendered it as a JPG (or via any other decent compression scheme)? There is an enormous amount of spatial redundancy in most images. (I've worked at a couple of different jobs in the medical imaging field, one of which involved routinely generating 300 MByte data files in a few seconds. They wound up around 8-14 Mbytes after compression.) ---Rsk Rich Kulawiec rsk_at_gsp.org *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.gasp-seakayak.net/paddlewise/ ***************************************************************************Received on Thu May 14 1998 - 11:59:41 PDT
