"Limitations with large images or animated images", by thechange

This is actually a DirectX related issue dealing with the maximum size of an image. This limitation exists when using the CreateImage, CreateAnimImage, LoadImage, LoadAnimImage and SaveImage commands.

Code

;------------------------------------------------------------------------------;
; It seems that some videocard drivers are not capable of storing and/or
; displaying images larger than the current or a certain display resolution.
; Also when using AnimImages or anim strips, e.g. using the LoadAnimImage or
; CreateAnimImage commands, the image loaded takes up the total space of the
; number of frames. So for example if you have a spaceship bitmap, 64 pixels
; wide and 64 pixels high, you want to rotate and store in 1 degree increments,
; so 360 images. If you store this as 1 single image, this will definitely give
; some problems on some machines. It can even crash a computer. But if not,
; displaying separate, large images could also slow down a game significantly.

; The best solution in preventing this is keeping all single images below the
; dimensions of the used screen resolution (for example 640x480). If one has
; the need for a large bitmap, one can slice'n dice before loading all of the
; images separately and then displaying them side by side, like a tiled image,
; making it look like a glued set of images in-game. It is also known that
; SaveImage will export distorted or garbled images when images are too large.
