Binary SignWriting revision 3 update

Thu Jun 17 13:57:08 UTC 2010

Hi Charles,

The symbols in the email are "0.7" in size.  I prepared the email using 
the SignWriting Image Server.  My development version of SWIS can 
produce both the cartesian and polar markups. 

Here's the raw polar markup:
B???330°16???129°14  B???169°21???252°6???80°11???19°21

Once I can get a font file created, the above markup will show the 
actual symbols rather than the unknown code point boxes.

To fake it, I deleted the unknown code point boxes so I could replace 
them with the symbol graphics.

In SWIS, I used the Symbols page.  I changed the size to ".7" and press 
view.  Then I dragged the symbols to the desktop.  Then from the desktop 
into the email.

Regards,
-Steve
