DrawTriangle method
Draws a filled triangle frame on the specified position with the specified width and height on the image using the specified color, style and opacity.
Syntax
Boolean DrawTriangle(nLeft As Number, nTop As Number, nWidth As Number, nHeight As Number, nOrientation As Orientation, nFillColor As Number, nFillOpacity As Number, nPenColor As Number, nPenOpacity As Number, nPenStyle As Pen, nPenWidth As Number, bPenAntiAliasing As State)
Return value
Returns true if the function succeeded.
Parameters
Parameter | Type | Required | Description |
nLeft | Number | Yes | Specifies the horizontal coordinate. |
nTop | Number | Yes | Specifies the vertical coordinate. |
nWidth | Number | Yes | Specifies the width. |
nHeight | Number | Yes | Specifies the height. |
nOrientation | Orientation (Enumeration) | Yes | Specifies the orientation of the triangle. |
nFillColor | Number | Yes | Specifies the fill color. |
nFillOpacity | Number | No | Optional parameter containing the opacity percentage (where 0% is completely transparent). |
nPenColor | Number | No | Optional parameter containing a color value. If no color is specified, the current pen color will be used instead. |
nPenOpacity | Number | No | Optional parameter containing the opacity percentage (where 0% is completely transparent). If no opacity is specified, the current pen opacity will be used instead. |
nPenStyle | Pen (Enumeration) | No | Optional parameter containing the desired line style. If no style is specified, the current pen style will be used instead. |
nPenWidth | Number | No | Optional parameter containing the desired line width (thickness) in pixels (ranging from 1...100). If no width is specified, the current pen width will be used instead. |
bPenAntiAliasing | State (Enumeration) | No | Optional parameter enabling or disabling line anti-aliasing. If not specified the current pen anti-aliasing setting will be used instead. |
Example
The example below shows how to use the method. If you take a look at the example code, assume there is a reference to the Marblecore Imaging object with the name 'MarblecoreImaging'. Transparent parts of the image are displayed using a checkerboard pattern.
