DxBrushCache

Full name Microsoft.VisualBasic.Drawing.DirectX.DxBrushCache Assembly Microsoft.VisualBasic.Drawing.DirectX Members 6

The direct2d resource cache of a render target.

00 Remarks

Creating a direct2d brush / text format / stroke style object is a relatively expensive com operation, drawing a large amount of the polygon primitives with the same color should reuse the same brush object instead of creating a new one for each primitive.
