Flatten()
Approximates the loop as a straight polygon, cutting each arc finely enough that it strays no further than the automatic share of its radius.
public GeoPolygon2 Flatten()Returns
- GeoPolygon2
The straight polygon, which every operation over regions can read.
Flatten(double)
Approximates the loop as a straight polygon, cutting each arc so that it strays no further than a chord tolerance.
public GeoPolygon2 Flatten(double chordTolerance)Parameters
chordTolerancedoubleThe largest gap allowed between a piece and the arc it replaces, in drawing units. Zero picks the automatic share of each radius.
Returns
- GeoPolygon2
The straight polygon.
Remarks
The chords of an arc lie inside it, so a loop bulging outward encloses a little less once it is flattened, and one bulging inward a little more.
Exceptions
- ArgumentOutOfRangeException
Thrown when the tolerance is negative or not a number.
