Tomas -
I am no expert on the programming side of the x-y coordinate issues,  
however, I do know that some programs are accomplishing it  
beautifully...For example, in this paper on the web, Antonio Carlos  
discusses x-y coordinates in relation to SWML and SVG:

plus these two papers...

SignMatching with x-y coordinates:

Unicode related project in France

And obviously SignPuddle is handling the x-y coordinates well...

Regarding TrueType fonts and the x-y coordinates, I assumed that the  
True Type would have to be Unicode approved first, before we could  
assess that issue.

Some of Stefan's fonts have complete signs on one those rare  
fonts would not have an x-y coordinate issue!

But the individual symbols have to be on separate keys, to create  
signs...So the typist can type all variations of each sign...

Right now, with the fingerspelling fonts, we open a graphics program  
and use a mouse to push the symbols around ;-))

Val ;-)

I know how this works ;)

I need to know how to put these symbols together... In these fonts  
there is always only the symbol. Not a sign. I am interested in how  
to coordinate symbols in the relation to other symbols in the sign.  
It is other level of the sign rendering. First level is how to render  
each symbol (It is the TrueType font graphics level).
The second level is how to render the sign from these symbols...  
there you need to know the positions of these symbols, these  
coordinates I am talking about ;) I suppose it will be simillar  
coordinate system as in vector fonts, but it is different type of  
coordinates ;)
