GeometryPolyPolygon Method

Introduces multiple polygons to the vectorization context. These polygons can be defined with various properties including shape, opacity, outlines, etc. It can draw multiple identical polygons and multiple different polygons at the same time. If some of the parameters are not defined, they are taken from the current SubEntityTraits properties.

abstract PolyPolygon : 
        numPolygonPositions : UInt32Collection * 
        polygonPositions : Point3dCollection * 
        numPolygonPoints : UInt32Collection * 
        polygonPoints : Point3dCollection *

        fillOpacities : TransparencyCollection -> bool

Parameters

numPolygonPositions UInt32Collection: [in] Count array for each polygon index. Values of this array represent the number of each kind of polygon.
polygonPositions Point3dCollection: [in] Array of polygon positions (offsets for each polygon).
numPolygonPoints UInt32Collection: [in] Number of vertices for the polygons.
polygonPoints Point3dCollection: [in] Vertices of each polygon.
outlineColors EntityColorCollection: [in] Array of outline colors for polygon types. One outlineColor per polygon index.
outlineTypes LinetypeCollection: [in] Array of outline types for polygon types. One outlineType per polygon index.
fillColors EntityColorCollection: [in] Array of fill colors for polygon types. One fillColor per polygon index.
fillOpacities TransparencyCollection: [in] Array of opacity objects for polygons. One fillOpacity per polygon index.

Return Value

Boolean
true. This method also throws a corresponding exception if it fails.

Remarks

Example API call (where [] represents an array):

Copy

polyPolygon ([100, 7], [100 + 7 = 107 total positions], [4, 6], [4 + 6 = 10 total points], [outlinecolor0, outlinecolor1], [pattern0, pattern1], [fillcolor0, fillcolor1], [opacity0, opacity1]);

*100 identical 4-point polygons (polygon index 0) of outlinecolor0, pattern0, fillcolor0, opacity0, and *7 identical 6-point polygons (polygon index 1) of outlinecolor1, pattern1, fillcolor1, opacity1.
