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. This is done by shading the pixels along the borders of the affected lines.
Font anti-aliasing slows down the drawing of the resulting bitmap.
Font anti-aliasing can only be used if PDFDisplayDepth property is set to 8 or greater.
