void avl::RegionUnion ( 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 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.
