Draw Line Segments (anti aliased)

Drawing line segments, Distances from line segments, and line segment masks

Description

computes the distance from a given line segment (in 2d) or draws an anti aliased line

see http://mathworld.wolfram.com/Point-LineDistance2-Dimensional.html for computation of the orthogonal distance to the line.

Where appropriate, gets the orthogonal distance to the line, or one of the two end points.

Can be used to make anti aliased line segment(s) drawings / masks (see lineMask.m)

Can also be used to compute the distance from multiple line segments by taking the minimum of the distances to each line segment.
