EN FP, Fill Polygon 21-31
FP, Fill Polygon
This command fills the polygon currently in the polygon buffer. Use
FP to fill polygons defined in polygon mode or with the Edge
Rectangle or Edge Wedge commands (EA, ER, EW, RA, RR, or WG).

FP [;]
z Fill Method — Specifies the algorithm used to determine which
portions of the polygon are “inside” the polygon and therefore are
to be filled:
• 0 -- Even/odd fill algorithm (default)
• 1 -- Non-zero winding fill algorithm
Note Even/odd (method 0) and Non-zero (method 1) winding fill methods
are described in detail under “Filling Polygons,” earlier in this chapter.
The FP command fills any polygon that is currently in the polygon
buffer. FP accesses the data in the polygon buffer, but does not
clear the buffer or change the data in any way.
