RegionSymmetricDifference


Computes a region containing pixels from first or second input region, but not from both.

Syntax

C++
C#
 
void avl::RegionSymmetricDifference
(
	const avl::Region& inRegion1,
	const avl::Region& inRegion2,
	avl::Region& outRegion
)

Parameters

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

Description

The operation computes the logical symmetric difference of two given regions. That is, the resulting region contains pixel locations that belong to one of the given regions, but not to both of them. Both dimensions (width and height) of the resulting region are set to the maximum of the corresponding dimensions of the input regions.

Examples

RegionSymmetricDifference run on the sample regions.

Errors

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