Cannot open big images, size limitet of LongInt, not Int64

Cannot open big images, size limitet of LongInt, not Int64..

May bi, add compile defines for CPU x86_64 to use big images? And open images in stream as TFileStream for not use RAM?

That's right, size in TImageData should be Int64 or NativeInt rather. More troubles would be with some IO functions and some image format loaders/savers. What are you most interested in?

I used memory mapped files as Bits in TImageData for big images in a project using Imaging many years ago - I'll see if it could be resurrected (at least as a demo).

I think NativeInt will be more compatible, since you won't have to create separate code for different compiler directives like {$DEFINE CPUX86_64}. And thanks for the answer! :-)
