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. |
