LINE/DRAW | xstart=Real ystart=Real xend=Real yend=Real [colour=Colour] [line_type=LineStyle] [line_thickness=Real] | Draws a line on a graphics device. |
LINE/ALTER | [xstart=Real] [ystart=Real] [xend=Real] [yend=Real] [colour=Colour] [line_type=LineStyle] [line_thickness=Real] object=Gobject | Alters a previously drawn line. |
example:
#Draw a line >> aline = line:draw(0.0, 0.0, 1.0, 1.0, line_type=$dash) # Want the line type to be dot-dash >> line/alter line_type=$dot-dash object=aline
