Blit a multi-rectangular area within a region
int PhMultiBlit( PhRid_t rid,
unsigned short nrects,
const PhRect_t rects[],
const PhPoint_t *offset );
- rid
- A pointer to a region ID from which the function will blit an area defined by rects.
- nrects
- The number of items in the rects array.
- rects[]
- A pointer to an array of PhRect_t structures that define the areas the function blits. The areas can overlap; Photon detects the overlaps and the contents are blitted only once.
- offset
- A pointer to a PhPoint_t that defines an offset for the blitted area defined by rects.
ph
This function “blits” the multi-rectangular area that is defined by the PhRect_t structures pointed to by rects and whose origin is defined by the origin of the region specified by the PhPoint_t structure pointed to by rid. The area is blitted by the given offset. Other windows aren't affected by the blit.
- A nonnegative value
- Success.
- -1
- The blit failed, possibly because rid was
incorrect or the Photon Manager wasn't running.
