According to what I have heard. The cfimage tag is much more than just the standard Java image manipulation libraries out there. It also incorporates a large amount of "proprietary Adobe code" which was re-written in Java just for Scorpio. (I'm thinking photoshop...)
Personally I think that kicks butt because this is one place where CF can do stuff (or at least produce quality) that the standard Java stuff can't. As far as the performance-- I dunno. Are the file sizes very large? Perhaps Disk I/O is bottlenecking. You should totally check out Ben Nadel's blog entry showing how to easily use cfthread to asynchronously process multiple images. http://www.bennadel.com/index.cfm?dax=blog:749.view He's doing a cfhttp, but I'm sure the same could be used to crank through your images 5 or 10 at a time. ~Brad -----Original Message----- From: Zaphod Beeblebrox [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 21, 2007 9:41 AM To: CF-Talk Subject: Re: cfimage resize running very slow I'm curious what cfimage uses behind the scenes. If it's the java image libraries, I wouldn't be surprised with the speed issues as I had trouble with them when used as a cfobject.
