Hi Fred - Fortunately, it isn't actually necessary to use a 400+MB file to test for the problem. I am uploading a 500M pixel file to an ftp site that I will point you to shortly. This file is 1 bit per pixel and using group 4 compression is only about 6MB in size. Hopefully that will download a lot faster, and it will still trigger the 2GB pixel cache limit if it exists (500M pixels * 5 bytes per pixel = 2.5GB).
Thanks for your help! s/KAM ----- Original Message ----- From: "Fred Bazolo" <[EMAIL PROTECTED]> To: "gimp users" <[EMAIL PROTECTED]> Sent: Wednesday, January 08, 2003 11:22 PM Subject: Re: [Gimp-user] GIMP Image Size Limits Whew! That would be a test of my system! Like I mentioned earlier, the largest files I ever tried to work with were about 100 MB, and although it worked it was too annoying to bother with. But it would be fun to try a 400 mb file. I could just set the preferences parameters really high, close down everything else and see what happens. It will take a few minutes just to download a 400 mb file! On Thursday 09 January 2003 00:11, Kevin Myers wrote: > Sorry Fred and all, my apologies, 400KB was a serious typo.
