CHAPTER 10. DRAWING OPTIONS




Figure 10.1: Line joint shapes.




Figure 10.2: Line cap shapes.

• :coordinate - this means that the same units should be used for line thickness as are
  used for coordinates. In this case, the line thickness is scaled by the medium's current
  transformation, whereas :normal and :point do not scale the line thickness.
  

=> :line-thickness [Option]
=> line-style-thickness line-style [Generic Function]
The thickness, in the units indicated by line-style-unit, of the lines or arcs drawn by a
drawing function. The thickness must be a real number. The default is 1, which combined with
the default unit of :normal, means that the default line drawn is the "comfortably visible thin
line".

=> :line-joint-shape [Option]
=> line-style-joint-shape line-style [Generic Function]
Specifies the shape of joints between segments of unfilled figures. The possible shapes are :miter,
:bevel, :round, and :none; the default is :miter. Note that the joint shape is implemented by
the host window system, so not all platforms will necessarily fully support it.

=> :line-cap-shape [Option]
=> line-style-cap-shape line-style [Generic Function]
Specifies the shape for the ends of lines and arcs drawn by a drawing function, one of :butt,
:square, :round, or :no-end-point; the default is :butt. Note that the cap shape is imple-
mented by the host window system, so not all platforms will necessarily fully support it.
