Computes a region containing pixels from both input regions.


void avl::RegionUnion
	const avl::Region& inRegion1,
	const avl::Region& inRegion2,
	avl::Region& outRegion


Name Type Default Description
inRegion1 const Region& First input region
inRegion2 const Region& Second input region
outRegion Region& Output region


The operation computes the logical union of two given regions. That is, the resulting region contains pixel locations that belong to one or both of the given regions. Both dimensions (width and height) of the resulting region are set to the maximum of corresponding dimensions of the input regions.


RegionUnion run on the sample regions.


Error type Description
DomainError Input and output regions are not distinct in RegionUnion.
