Construction
Constructs a CRgn object. |
Initialization
Sets a CRgn object so that it is equivalent to the union of two specified CRgn objects. |
|
Sets a CRgn object so that it is a copy of a specified CRgn object. |
|
Initializes a CRgn object with an elliptical region. |
|
Initializes a CRgn object with an elliptical region defined by a RECT structure. |
|
Creates a region from the given region and transformation data. |
|
Creates a region from the path that is selected into the given device context. |
|
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. |
|
Initializes a CRgn object with a region consisting of a series of closed polygons. The polygons may be disjoint, or they may overlap. |
|
Initializes a CRgn object with a rectangular region. |
|
Initializes a CRgn object with a rectangular region defined by a RECT structure. |
|
Initializes a CRgn object with a rectangular region with rounded corners. |
Operations
Checks two CRgn objects to determine whether they are equivalent. |
|
Returns a pointer to a CRgn object when given a handle to a Windows region. |
|
Fills the specified buffer with data describing the given region. |
|
Retrieves the coordinates of the bounding rectangle of a CRgn object. |
|
Moves a CRgn object by the specified offsets. |
|
Determines whether a specified point is in the region. |
|
Determines whether any part of a specified rectangle is within the boundaries of the region. |
|
Sets the CRgn object to the specified rectangular region. |
Operators
