Example

Example 1:

sis.RedrawExtent (SIS_CURRENTWINDOW, 0, 0, 0, 1000, 1000, 1000)

Example 1 redraws the current window only to the specified extents.

Example 2:

sis.Redraw (SIS_CURRENTWINDOW, 0, 0, 0, 1000, 1000, 1000 Or SIS_QUICK_REDRAW)

Replace "Or" with the bitwise-or operator in your language of choice.

Example 2 causes the cached bitmap to be blitted, then the Sprites Overlays drawn, using the SIS_QUICK_REDRAW flag.
