DirectDraw + Pitch
Posted on 2000-02-17
When would the pitch change? Do I have to use the value returned by the lock function every time or can I assume that the value returned by the lock function will stay the same as long as the application doesn't change the surfaces layout?
If I create a surface, do some blitting, restore it when it has gone and than continue blitting, will the Pitch value stay the same?
So one call to a lock function can give me the Pitch value for the rest of the "life" of the surface?
