Remarks

The following table lists public properties and methods added by this class to its parent class, gpBase. This class also implements the Clone and Init methods.

Properties and methods	Description
Clone Method	Clones a point object. Syntax: `? THIS.Clone(toGpPoint)` Return Values: Logical, representing success or failure. Parameters: toGpPoint, required, the gpPoint-based object to clone.
Create Method	Creates a point object from specified coordinates. Syntax: `THIS.Create(tX,tY)` Return Values: Logical, representing success or failure. Parameters: tX, required, the X coordinate for the point to create. tY, required, the Y coordinate for the point to create.
GdipPoint Property	String representing the GDI+ Point structure (composed of two 32-bit integers). Default: Empty.
GdipPointF Property	String representing the GDI+ PointF structure (composed of two 32-bit single-precision float values). Default: Empty.
Init Method	Constructs a Point object during initialization if passed appropriate arguments. Syntax: `CREATEOBJECT("gpPoint" [,tX,tY])` Return Values: Logical, representing success or failure. If the method fails, the object does not instantiate. Parameters: tX, required if immediate creation of the object is requested, represents the X coordinate for the point. tY, required if immediate creation of the object is requested, represents the Y coordinate for the point.
Set Method	Sets a point object from specified coordinates. Syntax: `THIS.Set(tX,tY)` Return Values: Logical, representing success or failure. Parameters: tX, required, the X coordinate for the point to set. tY, required, the Y coordinate for the point to set.
X Property	The X-coordinate of the point. Default: `0`.
Y Property	The Y-coordinate of the point. Default: `0`.
