does any one know the size of a direct draw surface?
does its size change based on the size of a picture you put in it?
what is its size if its just been defined and it is not yet holding a picture?
where is the sdk for dx7 (vb) i could'nt find it at the mircrosoft web site
And for that size of surface question...look here
i meant size like in bytes
I'm just guessing here, but I think you can calculate it if you multibly hight and width and the bit dept....
What exactly do you need to know its size for? If you're planning on copying the contnets to your own data buffer, just allocate enough space for the width x height x sizeofpixel (which I assume you would know in advance if you're going to be working with the image data, and it should just depend on the depth - 1, 2, 3, or 4 bytes per pixel).
Height*Pitch*BPP for the real data size of the surface.
