1.4.8 Special effects
Anti-aliasing
Anti-aliasing manipulates line borders of polygons in sub-pixel units and blend the pre-drawing pixel
color with color to make the jaggies be seen smooth. It is used as a functional option for 2D drawing
(in direct color mode only).
Bold line and broken line drawing
This function draws lines of a specific width and a broken line.

Description
Selectable from 1 to 32 pixels
Set by 32 bit or 24 bit of broken line pattern
• Supports the verticality of starting and ending points.
• Supports the verticality of broken line pattern.
• Interpolation of bold line joint supports the following modes:
(1) Broken line pattern reference address fix mode
→ The same broken line pattern is kept referencing for the period of some pixels starting from the
joint and the starting point for the next line.
(2) No interpolation
• Supports the equalization of the width of bold lines.
• Supports the bold line edging.
• Not support the Anti-aliasing of dashed line patterns.
• For a part overlaid due to connection of bold lines, natural overlay can be represented by providing depth
information. (Z value).
Shading
Supports the shading primitive.
Drawing is performed to the body primitive coordinates (X, Y) with an offset as a shade. At this drawing,
the Z buffer is used in order to differentiate between the body and shade.
