Region Basics

Select a filter from the list below.

Name	Description / Applications	Modules
CreateBoxBorderRegion	Creates a frame-shaped region with given parameters.	FoundationLite
CreateBoxRegion	Creates a rectangular region corresponding to a given box.	FoundationLite
CreateCircleRegion	Creates a circular region corresponding to a given circle.	FoundationLite
CreateCrossRegion	Creates a cross-shaped region with given parameters.	FoundationLite
CreateEllipseRegion	Creates an elliptic region of given bounding rectangle.	FoundationLite
CreateGridRegion	Creates a grid-shaped region with given parameters.	FoundationLite
CreateLineRegion	Creates a line region.	FoundationLite
CreatePathBorderRegion	Creates a region along a given path. The region may be internal or external to the path.	FoundationLite
CreatePathRegion	Creates a region along the given path.	FoundationLite
CreatePolygonRegion	Creates a polygonal region corresponding to a given closed path.	FoundationLite
CreateRectangleBorderRegion	Creates a frame-shaped region with given parameters.	FoundationLite
CreateRectangleRegion	Creates a region corresponding to a given rectangle.	FoundationLite
CreateRingRegion	Creates a ring-shaped region with given parameters.	FoundationLite
CreateSegmentRegion	Creates a segment region.	FoundationLite
EmptyRegion	Creates an empty region with a given frame.	FoundationLite
GetRegionFrame	Returns the width and height of the entire region's frame (not to be confused with RegionBoundingBox!).	FoundationLite
LocationsToRegion	Forms a region containing pixels of given locations.	FoundationLite
RegionCharacteristicPoint	Returns a characteristic point of the input's region bounding box.	FoundationLite
RegionToLocations	Converts a region to an array of its pixel locations. It may be considered explicit region decompression.	FoundationLite
SetRegionFrame	Changes the width and the height of a region's frame (but does not rescale the content).	FoundationLite
SkipEmptyRegion	If the input region contains at least one pixel, then it is copied to the output; otherwise Nil is returned. Secures against domain errors caused by empty regions, e.g. just before the RegionMassCenter filter is to be invoked.	FoundationLite
TestRegionEmpty	Tests whether the size of a region equals zero.	FoundationLite
TestRegionNotEmpty	Tests whether the size of a region doesn't equal zero.	FoundationLite
TestRegionOnBorder	Tests whether a region is adjacent to its border.	FoundationLite
VerifyRegion	Checks if the point-runs of the input region are correctly arranged (sorted, not overlapping etc.). You only need to use this tool if you create regions from point-runs manually.	FoundationLite
