[Mapserver-users] SVG Output

[Steve Lime]

There are 2 new additions:

  - In query templates there is a new tag called shpxy. It allows for
ad hoc access to the coordinates for any returned shape. There are a
bunch of tag attributes that allow you to structure the output in a
variety of ways. I'll have to check the source and post a summary of
those. In practice you could then setup a query template that looked
like:

<path id="[shpidx]" d="M [shpxy] ">
  ... more svg stuff if necessary ...
</path>

and then build up a svg document with the addition of headers and
footers.

 - In the map file you can now set an arbitrary MIME-TYPE for query
output using a web object parameter called QUERYFORMAT. So, for example
you might do:

  QUERYFORMAT "image/svg+xml"

I'm not real happy with this mechanism, I'd rather use OUTPUTFORMAT
blocks, but for now this works just fine.

4.1 will be released as 4.2 after the first of the year. Don't know
exactly when. The CVS code is VERY stable so I'd be interested in
feedback.

Steve,

Thanks for your reply.

Is there any more information available on these new features? Any idea

on when 4.1 is available?
