You’re right of course. I missed a "/ 2" I have further down in my code. Corrected note to add to the spec: Given: * <var>A</var> the angle (in any quadrant) defining the gradient line’s direction such that 0 degrees points upwards and positive angles represent clockwise rotation, * <var>W</var> the width of the gradient box, * <var>H</var> the height of the gradient box, The size of the gradient line (between the starting and ending point) is: <code>abs(W * sin(A)) + abs(H * cos(A))</code> -- Simon Sapin
