Aliasing is the effect on all pixel devices where diagonal and curved lines have a zigzag appearance. As pixels get larger, this effect becomes more noticeable. Anti-aliasing refers to methods designed to decrease or eliminate this effect. Anti-aliasing is done by shading the pixels along the borders of the affected lines.

This affects the PDF format when UsePdfEngine is set to true to use Leadtools.PdfEngine.dll. It also affects the Postscript format.

Example
For an example, refer to CodecsPdfOptions.
