hi, is there a simple (ie built-in) way to obtain a list of indices (points) of a 2d-array that would be "touched" if a line was drawn? example: 2d-array bob 100x100 if we "draw" from 20,20 to 27,32 i would like a list of "touched" indices like (20 20 21 23 ...) returned basically the equivalent to graphics:compute-cubic-spline-points but for a simple line -thanks
