Line Suppression

Line suppression. These options can be combined.

0 = Closed rectangle
Bit 0 = 1 = Suppress top line (smallest Y value)
Bit 1 = 1 = Suppress right side line (largest X value)
Bit 2 = 1 = Suppress bottom line (largest Y value)
Bit 3 = 1 = Suppress left side line (smallest X value) NOTE: When drawing a filled rectangle with line suppression, only the pixels that are on the border of the rectangle are suppressed (not drawn). The line width must be taken into account to determine the width of the border.
