DrawPolygonFilled method
Draws a filled polygon on the specified position on the image using the specified color, style and opacity.
Syntax
Boolean DrawPolygonFilled(strPoints As String, nFillColor As Number, nFillOpacity As Number, bAntiAliasing As Boolean)
Return value
Returns true if the function succeeded.
Parameters
Parameter | Type | Required | Description |
strPoints | String | Yes | Specifies the points for the polygon as a string. Each point pair is separated with a semicollon (;). Within each point the horizontal and vertical coordinate is separated with a comma (,). Example string: 0,100; 25,50; 50,0; 100,100. |
nFillColor | Number | Yes | Specifies the fill color. |
nFillOpacity | Number | No | Optional parameter containing the opacity percentage (where 0% is completely transparent). |
bAntiAliasing | Boolean | No | Optional parameter enabling or disabling anti-aliasing. Enabled by default. |
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.
