Hi Jonathan,<br>
<blockquote cite="mid:538945C1.9070203@yahoo.ca" type="cite">The

Each base symbol has an 8-bit number for the valid fills and a
16-bit number for the valid rotations. So each base symbol needs
3-bytes to determine validity.<br>

Here is a table from draft-slevinski-signwriting-text that deals
with validity in the ISWA 2010.<br>

For the punctuation in question, it has valid fills of 1 thru 4 (
sum value of 15) and it has valid rotations of 1 thru 8 (sum value
of 255). So to send the information for the base symbol we would
need S387,15,255. For any symbol key, we can use the associated
fill and rotation numbers to determine if the key is valid.<br>

The advantage is that we do not need to have a bit for each and
every cell. With 6 fills and 16 columns, we would need a 96-bit
number which is 12-bytes. So to send the information for the base
symbol we would need S387,71777214294589695 or we could use 6
16-bit numbers which would be S387,255,255,255,255,0,0<br>
<br>
Setting each individual cell would require 4 times as much data
per base symbol. I chose the smaller representation because I was
trying to reduce the size as much as possible.<br>
</blockquote>
Thanks for explaining why just writing the valid fills and valid
rotations is so much more efficient than a validation bit for each
possible character.<br>
