Prototype

DECLARE SUB DQBline (BYVAL Layer, BYVAL x1, BYVAL y1, BYVAL x2, BYVAL y2,
                     BYVAL Col)

Parameters

Layer - Layer where to draw the line onto

x1 - First point x coordinate

y2 - First point y coordinate

x2 - Second point x coordinate

y2 - Second point y coordinate

Col - Drawing color

Returns

none

Description

This procedure draws a line from point at (x1,y1) to point at (x2,y2), on the given layer and with specified color. The Bresenham's line algorithm is used.
