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

ParameterTypeRequiredDescription
strPointsStringYesSpecifies 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.
nFillColorNumberYesSpecifies the fill color.
nFillOpacityNumberNoOptional parameter containing the opacity percentage (where 0% is completely transparent).
bAntiAliasingBooleanNoOptional 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.
 
 
1 // Creates a new transparent image
2 MarblecoreImaging.Create(150, 150, true);
3 
4 // Execute the operation
5 MarblecoreImaging.DrawPolygonFilled("25,75; 75,25; 125,125", 16711680);
6 
7 // Save the modified image to the specified file
8 MarblecoreImaging.SaveToFile("example-drawpolygonfilled.jpg");
