Hi Thomas,
Next I tried to apply the static attribute to my more dynamic mapping
examples.
Here is the URL:
http://www.carto.net/papers/svg/postgis_geturl_xmlhttprequest/example.svg
[...]
In that case I am not that sure if the static attribute fully works. It
seems to run somehow faster, but not as fast as in the first two examples.
Yes, I have noticed this, and I am not sure why it is not as big
a difference. I suspect that the Java2D renderer is dropping into
a lower performance drawing case, when I get the change I may play
with it more. I would check things like clip-paths and the like.
that would be very nice, if you could do some further investigations
here. I don't use clip-paths here. I only move the content in a nested SVG.
The structure looks like the following:
<svg>
<!-- the gui, screen oriented coordinate system -->
<svg><!-- the map coordinate system, usually in meters or degrees -->
<g batik-static="true" transform="translate(x,y)"> <!-- the static
attribute set by script, translate attribute set while dragging -->
<!-- map content, mostly path, but also text and sometimes
use-elements -->
</g>
</svg>
</svg>
I don't know if the problem is because of the nested SVG? But in the
mapWaadt.svg and mapSpain.svg example we also move the content within a
viewBox (not nested, but clipped to the viewBox area).
Please let me know if there is anything more to test or to change in my
code.
Thanks a lot,
Andreas
