Copy a Surface

Thierry,

Would it be possible to have a function would create an exact copy of a Surface, same width, height, and pitch, with an option to copy the contents also?

In other words, create a copy of the Back Surface (or any surface) so that memcpy can be used.

Thanks,

Pam

Are we talking PF or PHAL here?

Well the idea was to create an effect, like the water or fire effects that typically use two buffers. You loop through one buffer to figure out what goes in the second buffer, Blit the second buffer, then swap and do the whole thing again.

Of course one wouldn't often use the backbuffer for this, only if it was a fullscreen effect.

The other thread about the 3x3 matrix blur got me thinking about it.
