Section 23 G2D
Notes: 1. 8-point drawing is used for a line width of 1. Both of the 8-point drawing and 4-point
drawing are used for bold line drawing.
2. The final point of each line segment is drawn. When the starting and final coordinate
points of a line segment match, a single dot is drawn for a line width of 1 and nothing
is drawn for bold line drawing.
3. When AA = 1, note the following:
• When the starting and final coordinate points of a line segment match, antialiasing
is not performed.
• Antialiasing is not performed for horizontal, vertical, and 45-degree diagonal line
segments.
4. The final coordinate point before coordinate transformation is stored as the current
pointer values (XC, YC).
