I have a question: How do I get a pointer to an image from within my dll (I'm not after the current bitmap, or backbuff data, but DB-Pro Images). I do not need to know how to access DB-Pro functions (that's the easy bit), but I need to have access to the actual image data (without having to create memblocks from images and passing the pointers to the memblocks, although that would work - just too slowly). And if anyone can provide the structure of the image data too that would be awsome!

I'm guessing I will need to access the 'image exist' function, but I still don't know how to get a pointer to the actual image.

Can anyone help me on this?

You'll want either GetImageData, though I don't know how to call it, or what it provides you.

void __cdecl GetImageData(int,unsigned long *,unsigned long *,unsigned long *,char * *,unsigned long *,bool)

Or you can get a pointer to the texture by using GetPointer. After getting this you can go read the DX docs on how to use it.

Both functions are in the DBProImageDebug DLL.
