Re: [Gimp-developer] GIMP Image Size Limits

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.
