◆ SetClipRegion()

bool CGraphicContext::SetClipRegion ( float  x,
float  y,
float  w,
float  h 
)

Set a region in which to clip all rendering Anything that is rendered after setting a clip region will be clipped so that no part renders outside of the clip region. Successive calls to SetClipRegion intersect the clip region, which means the clip region may eventually become an empty set. In this case SetClipRegion returns false to indicate that no rendering need be performed.

This call must be matched with a RestoreClipRegion call unless SetClipRegion returns false.

Usage should be of the form:

if (SetClipRegion(x, y, w, h)) { ... perform rendering ... RestoreClipRegion(); }

Parameters
xthe left-most coordinate of the clip region
ythe top-most coordinate of the clip region
wthe width of the clip region
hthe height of the clip region
Returns
true if the region is set and the result is non-empty. Returns false if the resulting region is empty.
