Hi Tomáš,<br>
<br>
SignPuddle uses graphic files and something I call the build format.<br>
<br>
Here is the graphic and build string for ASL_2 in the ASL dictionary.<br>

The build format is a repeating string of symbol id, x coordinate, y
coordinate. <br>
<br>
As far as I can tell, for the next 10 years at least, the current
raster images of the IMWA will be the standard. The x, y coordinates
should be expressed in numbers that relate to the current raster images.<br>
<br>
When IMWA compatible SVG is possible, it should be possible to render a
build string with minimal processing. The X, Y coordinates only need
to change according to scale.<br>
<br>
I don't know the correct range for X, Y values. SignPuddle uses 1 to
250. I imagine the numbers could be very large in some situations, up
in the thousands.<br>
<br>
My thoughts,<br>

I am interested what is your opinion about x and y coordinates of the
symbol in a sign.
<br>
<br>
This information has to be saved with symbols to specify how to render
the sign.
<br>
<br>
Now there is raster data (PNG) used in SignPuddle and there was raster
data used in SignWriter DOS.
<br>
It was static and there was no problem to specify coordinates, because
it is in pixels or any other static measure.
<br>
<br>
But we all feel need of vector data (SVG, OpenType) to have nice
rendering in high zooms.
<br>
<br>
There we cannot say that a symbol has for example x = 10 pixels and y =
30 pixels.
<br>
If you zoom it, those coordinates has to be changed. So there must be
relative coordinates.
<br>
<br>
What range of x and y coordinates should be used?
<br>
<br>
IMHO -127 to 127 could be enough.
<br>
<br>
What do you think?
