Region Basics
Select a function from the list below.
Icon | Name | Description / Applications | |
---|---|---|---|
CreateBoxBorderRegion | Creates a frame-shaped region with given parameters. |
||
CreateBoxRegion | Creates a rectangular region corresponding to a given box. |
||
CreateCircleRegion | Creates a circular region corresponding to a given circle. |
||
CreateCrossRegion | Creates a cross-shaped region with given parameters. |
||
CreateEllipseRegion | Creates an elliptic region of given bounding rectangle. |
||
CreateGridRegion | Creates a grid-shaped region with given parameters. |
||
CreateLineRegion | Creates a line region. |
||
CreatePathBorderRegion | Creates a region along a given path. The region may be internal or external to the path. |
||
CreatePathRegion | Creates a region along the given path. |
||
CreatePolygonRegion | Creates a polygonal region corresponding to a given closed path. |
||
CreateRectangleBorderRegion | Creates a frame-shaped region with given parameters. |
||
CreateRectangleRegion | Creates a region corresponding to a given rectangle. |
||
CreateRingRegion | Creates a ring-shaped region with given parameters. |
||
CreateSegmentRegion | Creates a segment region. |
||
EmptyRegion | Creates an empty region with a given frame. |
||
GetRegionFrame | Returns the width and height of the entire region's frame (not to be confused with RegionBoundingBox!). |
||
LocationsToRegion | Forms a region containing pixels of given locations. |
||
RegionCharacteristicPoint | Returns a characteristic point of the input's region bounding box. |
||
RegionToLocations | Converts a region to an array of its pixel locations. It may be considered explicit region decompression. |
||
SetRegionFrame | Changes the width and the height of a region's frame (but does not rescale the content). |
||
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. |
||
TestRegionEmpty | Tests whether the size of a region equals zero. |
||
TestRegionNotEmpty | Tests whether the size of a region doesn't equal zero. |
||
TestRegionOnBorder | Tests whether a region is adjacent to its border. |
||
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. |
