In SVG, styles can be stated separately from everything else: as in my
Easter and Christmas cards, the style is in a small section at the
beginning of the file. You can go there and change "red" to "black" and
"yellow" to "white" or any other colours, and the style of all the
SignWriting will change.

In the style section I also offer a background colour which can be
replaced with a jpeg or other graphic file if desired, and a shadow
colour, used for distinguishing overlapping symbols. This isn't strictly
necessary as it would work to just make it the same colour as the fill,
but it was simple in SVG to let the writer make them different if he
wanted, so I used it.

I didn't have any trouble with this. My prototype draws the unfilled
hand first, then draws the fill as a shape on top of it, then draws the
white overhead line break on top of that. My SVG also does this.

There are some handshapes which would need special treatment for this, I
think, but as long as the shape can be drawn, it can be done.

As I explained in other emails, having the middle of the wrist as the
centre of rotation is true to life and works well.

Am I missing something about body shift? Body shift just means that the
whole sign is shifted right or left on the page, doesn't it? So all we
need is a number stating the x-distance to shift it, surely?
