The border surrounds the raster area and the shadow cast from it.
You can set the border's line style, weight (thickness) and colour as
well as the fill pattern with which the border should be drawn. For
the shadow border, Calamus will use the shadow's colour and fill
pattern. The functions of this function group are described in the
Calamus chapter Colour
. The functions for setting the line
style will be found in the chapter for the Line module.
