CRgn Class Members

Construction

CRgn Constructs a CRgn object.

Initialization

CreateRectRgn Initializes a CRgn object with a rectangular region.
CreateRectRgnIndirect Initializes a CRgn object with a rectangular region defined by a RECT structure.
CreateEllipticRgn Initializes a CRgn object with an elliptical region.
CreateEllipticRgnIndirect Initializes a CRgn object with an elliptical region defined by a RECT structure.
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.
CreateRoundRectRgn Initializes a CRgn object with a rectangular region with rounded corners.
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.
CreateFromPath Creates a region from the path that is selected into the given device context.
CreateFromData Creates a region from the given region and transformation data.

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

operator HRGN Returns the Windows handle contained in the CRgn object.
