Detailed Description

Class to implement the Bresenham line-drawing algorithm.

This object does not draw directly into an image, it simply outputs the set of image co-ordinates that should be visited to draw a line in a certain direction. Pixels are generated in a 8-connected sense (i.e. diagonal steps are possible). See also Brezenham.

dirThe (x,y) direction of the line

Member Function Documentation

ImageRef CVD::Brezenham8::sideways ( ) [inline]

Which compass position most orthogonal to the line's direction? At each pixel given by step() you are guaranteed to be able to walk in the direction given by sideways and not walk on the line.
