Notes
|
Determines whether text 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()) {
doc.Rect.Inset(50, 50);
// Add some text
doc.FontSize = 48;
doc.Pos.String = "50 690";
int id = doc.AddText("Abc");
// Render images
doc.Rect.String = doc.GetInfo(id, "rect");
doc.Rendering.AntiAliasText = true;
Bitmap antialiasedBitmap = doc.Rendering.GetBitmap();
doc.Rendering.AntiAliasText = false;
Bitmap aliasedBitmap = doc.Rendering.GetBitmap();
// Add enlarged images to the pdf file
doc.Rect.Magnify(5, 5);
doc.Rect.Move(0, -300);
doc.AddImageBitmap(aliasedBitmap, false);
doc.Rect.Move(0, -300);
doc.AddImageBitmap(antialiasedBitmap, false);
// Annotate
doc.Rect.String = doc.MediaBox.String;
doc.Color.String = "255 0 0";
doc.FontSize = 36;
doc.Pos.String = "50 740";
doc.AddText("Original text:");
doc.Pos.String = "50 620";
doc.AddText("Magnified aliased image:");
doc.Pos.String = "50 320";
doc.AddText("Magnified antialiased image:");
// Save render of pdf files
doc.Rendering.AntiAliasText = true;
doc.Rendering.DotsPerInch = 36;
doc.Rendering.Save(Server.MapPath("RenderingAntiAliasText.png"));
}
