Computes the orientation of a segment.
|inAngleRange||AngleRange||Switches between 0-180 or 0-360 degrees|
Note that because of inaccuracies of floating-point arithmetic, some geometric operations (including this one) may lead to unpredictable results for degenerated cases. In this filter such a case occurs when an empty segment is given on input.
This filter is available on Basic Complexity Level.
