Screen Capture 03 Cgi

written by Steve Maller steve@maller.com http://www.maller.com/ I run a Macintosh with a MacHTTP web server and an Apple Internet Mail Server in my office, and there are times I'd just like to peek at the Mac's screen. However, I don't like waiting for that machine's monitor to warm up. Even worse, I recently had to borrow that machine's monitor for another machine. My solution? I wrote this CGI application in CodeWarrior C that takes a screenshot of the current Macintosh screen, converts it to a GIF image, and returns it to your Web browser. I used Grant Neufeld's excellent framework (Grant's CGI Framework 1.0b10). Some notes about the current version (version 0.3) * This version returns only a GIF image. Thanks to Eric A. Perlman (eric@yikes.com) for the suggestion (and the instructions!). * This version is once again a fat binary. It's been tested on quite a few Power Macintosh models and it works just fine. I think I've figured out the problems (thanks to some help out there!). * The program is hard-coded to generate a 256-color, 640*480 GIF image. If your display's something other than that, it'll try to dither the image for the best possible quality.
