This method draws a polygon in the designated object.
Parameters
| Name | Explanation |
|---|---|
| DeviceValue | The device context or the raster image data (i.e. Hdc or ImageHandle) depending on the DeviceMode |
| x,y | An array of x and y coordinate values defining
points of the polygon
(1)In Visual C++, pass the pointer to the first element in the x and y arrays (2)In Visual Basic, Dim x(0 To 2) As Integer then set x(0) |
| Points | The number of points defining the polygon (2 or more) |
| DeviceMode | If 0 (ikScreen), then the polygon will be drawn in pixel units. If 1 (ikPrinter), the polygon will be drawn in 0.1mm units. If 2 (ikMemoryHandle), the polygon will be drawn (in pixel units) to the image data according to the DeviceValue parameter |
In Visual Basic the following constants can be used: (ikScreen = 0, ikPrinter = 1, ikMemoryHandle = 2).
Return Value
Returns True (nonzero) if successful. Returns False (0) if unsuccessful.
Explanation
The Polygon method draws a polygon in the designated object. This method draws a straight line from a designated point to another point and from there to subsequent points. The polygon is closed by drawing a line from the end point to the starting point. The points are specified by the x and y parameter arrays. The outline of the polygon is drawn from the value set in the PenStyle property and the polygon is filled by the value set in the BrushStyle property. This method can draw in the following designated objects: screen, printer, and image data. When drawing a polygon, it is recommended that the PenWidth, PenMode, PenColor, BrushColor, Transparent, and BackColor properties also be set. The BackColor property is enabled when the Transparent property is False and the pen is set to draw lines other than solid lines or the brush is set to hatch pattern.
For scripting languages and other programs that require variant types, please refer to the PolygonVariant method.
If the DeviceMode parameter is 0 or 2 then x and y parameters are in pixel units.
If the DeviceMode parameter is 1 then x and y parameters are in 0.1mm units.
