Determines whether polygons will be rendered with anti-aliased edges.

Anti-aliasing is a technique for using gradients of color to eliminate jagged edges when objects are drawn. The object edges are blurred to reduce pixelation.

The following example shows the effect that this parameter has on PDF rendering.

Set theDoc = Server.CreateObject("ABCpdf13.Doc")
' Add a polygon
theDoc.Color.String = "255 0 0"
theDoc.AddPoly "32 650 50 704 68 650 22 683 79 683 32 650", True
theDoc.Rect.String = "20 650 80 704"
' Render the drawn area with AntiAliasPolygons (default)
antiAliasedBitmap = theDoc.Rendering.GetData(".tif")
' Render the drawn area without AntiAliasPolygons
theDoc.Rendering.AntiAliasPolygons = False
aliasedBitmap = theDoc.Rendering.GetData(".tif")
' Add magnified aliased image
theDoc.Rect.String = "5 20 605 560"
theDoc.AddImageData aliasedBitmap, 1
' Anotate
theDoc.Color.String = "black"
theDoc.FontSize = 30
theDoc.Pos.String = "20 750"
theDoc.AddText "Original path:"
theDoc.Pos.String = "20 620"
theDoc.AddText "Magnified rendered image:"
' Render the document with aliased image
theDoc.Rendering.DotsPerInch = 36
theDoc.Rect.String = theDoc.MediaBox.String
theDoc.Rendering.Save "c:\mypdfs\RenderingAntiAliasPolygonsFalse.png"
' Add magnified antialiased image
theDoc.Rect.String = "5 20 605 560"
theDoc.AddImageData antiAliasedBitmap, 1
' Render the document with antialiased image
theDoc.Rendering.DotsPerInch = 36
theDoc.Rect.String = theDoc.MediaBox.String
theDoc.Rendering.Save "c:\mypdfs\RenderingAntiAliasPolygonsTrue.png"
theDoc.Clear
