Yes... All of that except ending the line in a dot.
There is no way to determine where in the pattern the line will end.

The function you want is stroke-dasharray
See http://www.cit.gu.edu.au/~anthony/draw/#mvg_settings
for examples of the major drawing and line settings.


If you are only drawing lines, then I would also turn off 'fill' or you
will get a 'filled' line with a single pixel fill color line underneath
the line.

See:  Drawing Lines, Line Width and Stroke
  http://imagemagick.org/Usage/draw/#strokewidth

Also note that strokewith is a floating point number, as it can be
scaled using other MVG drawing options.
