FoundationLite |
 |
CreateLineRegion |
|
Creates a line region. |
FoundationLite |

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. |

Tests whether a region is adjacent to its border. |
FoundationLite |
