If you're using it for 2D and the large image can be divided into smaller same sized images, then you can use LoadAnimImage(filename,width,height,first,count)
For example, suppose your 100,000 x 100,000 image is divided into a grid of 1,000x1000 squares.
that would make your grid 100 tiles across and 100 tiles down.
Pixel 90000,90000 would be located at tile 90,90
So the first parameter would be 90*100+90, or 9090
The Count parameter would be 1 to load in only one image.
The entire command would be
To be honest, I don't have any 100,000x100,000 images lying around to test this on, but it has worked on smaller sized images in the same way.
