FILL

101

FILL — FILL closed path

Format

FILL rule;

Parameter

rule:

drawing rule:

1 = use even-odd rule

2 = use non-zero winding number rule

Function

The FILL command fills the area enclosed by the current path with the current drawing

rule. It also fills all independent subpaths contained in a path. An open subpath is

implicitly closed before being painted (as done by a CLSP command). This command

clears the current path after filling and moves the cursor to the end of that path.

With drawing rule 1, even-odd, whether or not a point is deemed to be inside the path is

determined by drawing a ray from that point in any direction and counting the number of

times the ray crosses segments of the path. The point is deemed to be inside the path if

the result is an odd number; if the result is an even number, the point is deemed to be

outside the path.

The non-zero winding rule also draws a ray from a point in any direction to determine

whether or not that point is deemed to be inside the path and examines the points at

which a segment of the path crosses the ray. However, it then starts counting from zero

and adds one each time a segment in the path crosses the ray from left to right; and

subtract one each time a segment in the path crosses the ray from right to left. If the

result of counting all the crossings is zero, the point is deemed to be outside; otherwise

the point is deemed to be inside the path.

The way in which several filled-in parts are stacked with each other to produce

transparent and opaque effects is controlled by the SIMG (Set IMaGe model) command.
