distance_pl — Calculate the distance between one point and one line.
The operator distance_pl calculates the orthogonal distance between points (Row,Column) and lines, given by two arbitrary points on the line. The result is passed in Distance.
distance_pl calculates the distances between a set of n points and one line as well as the distances between a set of n points and n lines.
Row coordinate of the point.
Column of the point.
Row coordinate of the first point of the line.
Column coordinate of the first point of the line.
Row coordinate of the second point of the line.
Column coordinate of the second point of the line.
Distance between the points.
