PtBlit()

Blit an area within a widget

            PhPoint_t const *delta );

Library:

ph

Description:

This function blits the area that's defined by the PhRect_t structure pointed to by source (relative to the widget's origin) by an offset specified by the PhPoint_t structure pointed to by delta. Effects of the blit are limited to only the visible portions of the widget's canvas.

Returns:

0: Success.
