Thanks very much to Sven for this info. Well, since many of my images are rather large (in the 400 to 600 megapixel range), maybe I can provide some of the additional large image testing that is needed. But I have one problem. I'm running Windows, and can't seem to figure out how to get started building the GIMP under Windows. Presently I am using the binary installable 1.2.4 distribution, but I can't even figure out how to compile it using the source from Tor's web site. As descibed in my previous post, I can't even get through the first step, which is running ./configure . So, until I can solve this problem, there is no way that I can start trying to work with 1.3 . Any help getting my build process off the ground would be greatly appreciated. One more question related to size limits: How many bytes per pixel does the pixel cache use? I have a sneaking suspicion that the answer is 5 based on the image sizes where I'm running into problems. That's what ImageMagick uses for its pixel cache, and I run into problem at almost exactly the same image size. s/KAM ----- Original Message ----- From: "Sven Neumann" <sven@xxxxxxxx> To: "Kevin Myers" <KevinMyers@xxxxxxxxxxxxx> Cc: "gimp developers" <gimp-developer@xxxxxxxxxxxxxxxxxxxxxx>; "gimpwin developers" <gimpwin-dev@xxxxxxxxxxxxxxx> Sent: Monday, October 21, 2002 3:53 AM Subject: Re: [Gimp-developer] GIMP Image Size Limits > Hi, > > "Kevin Myers" <KevinMyers@xxxxxxxxxxxxx> writes: > > > Are there any known, inherent, limitations on the size of images > > that may be loaded and processed by the GIMP? > > yes.
