Construction

CRgn	Constructs a CRgn object.

Initialization

CombineRgn	Sets a CRgn object so that it is equivalent to the union of two specified CRgn objects.
CopyRgn	Sets a CRgn object so that it is a copy of a specified CRgn object.
CreateEllipticRgn	Initializes a CRgn object with an elliptical region.
CreateEllipticRgnIndirect	Initializes a CRgn object with an elliptical region defined by a RECT structure.
CreateFromData	Creates a region from the given region and transformation data.
CreateFromPath	Creates a region from the path that is selected into the given device context.
CreatePolygonRgn	Initializes a CRgn object with a polygonal region. The system closes the polygon automatically, if necessary, by drawing a line from the last vertex to the first.
CreatePolyPolygonRgn	Initializes a CRgn object with a region consisting of a series of closed polygons. The polygons may be disjoint, or they may overlap.
CreateRectRgn	Initializes a CRgn object with a rectangular region.
CreateRectRgnIndirect	Initializes a CRgn object with a rectangular region defined by a RECT structure.
CreateRoundRectRgn	Initializes a CRgn object with a rectangular region with rounded corners.

Operations

EqualRgn	Checks two CRgn objects to determine whether they are equivalent.
FromHandle	Returns a pointer to a CRgn object when given a handle to a Windows region.
GetRegionData	Fills the specified buffer with data describing the given region.
GetRgnBox	Retrieves the coordinates of the bounding rectangle of a CRgn object.
OffsetRgn	Moves a CRgn object by the specified offsets.
PtInRegion	Determines whether a specified point is in the region.
RectInRegion	Determines whether any part of a specified rectangle is within the boundaries of the region.
SetRectRgn	Sets the CRgn object to the specified rectangular region.

Operators

Returns the Windows handle contained in the CRgn object.
