<h4>Discussion</h4>
|
|
<p>This function returns one or more dirty rectangles that outline the frame areas that changed in the last call to <a href="BinkDoFrame.html">BinkDoFrame</a>. "Dirty rectangles" are the rectangles that enclose all of the pixels that changes from the previous frame to this frame. The dirty rectangles are placed in the FrameRects field of the <a href="BINK.html">BINK</a> structure. You will usually pass the dirty rectangle information directly to the <a href="BinkBufferBlit.html">BinkBufferBlit</a> function for blasting onto the screen. If you are using BinkBuffers, you can use the SurfaceType field in your BinkBuffer structure for the getrects_flags parameter. This function returns the number of dirty rectangles found.</p>
