Notes
|
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.

Example

The following example shows the effect that this parameter has on PDF rendering.
using (Doc doc = new Doc()) {
// Add a polygon
doc.Color.String = "255 0 0";
doc.AddPoly("32 650 50 704 68 650 22 683 79 683 32 650", true);
doc.Rect.String = "20 650 80 704";
// Render the drawn area with AntiAliasPolygons (default)
Bitmap antiAliasedBitmap = doc.Rendering.GetBitmap();
// Render the drawn area without AntiAliasPolygons
doc.Rendering.AntiAliasPolygons = false;
Bitmap aliasedBitmap = doc.Rendering.GetBitmap();
// Add magnified aliased image
doc.Rect.String = "5 20 605 560";
doc.AddImageBitmap(aliasedBitmap, false);
// Anotate
doc.Color.String = "black";
doc.FontSize = 30;
doc.Pos.String = "20 750";
doc.AddText("Original path:");
doc.Pos.String = "20 620";
doc.AddText("Magnified rendered image:");
// Render the document with aliased image
doc.Rendering.DotsPerInch = 36;
doc.Rect.String = doc.MediaBox.String;
doc.Rendering.Save(Server.MapPath("RenderingAntiAliasPolygonsFalse.png"));
// Add magnified antialiased image
doc.Rect.String = "5 20 605 560";
doc.AddImageBitmap(antiAliasedBitmap, false);
// Render the document with antialiased image
doc.Rendering.DotsPerInch = 36;
doc.Rect.String = doc.MediaBox.String;
doc.Rendering.Save(Server.MapPath("RenderingAntiAliasPolygonsTrue.png"));
