Hi,<br>
<br>
Thank you for your information on future plans about output based on
Cairo.<br>
<br>
Regarding the SVG support, my main concern is that if the output
goes through Cairo than there is no chance of adding attributes and
semantics to the vector features in SVG - am I correct? In SVG one
could f.e. embed title and description elements, as well as
non-graphical attributes in a separate namespace in the XML output.
Now that SVG support will be widespread in all browsers (IE9 will be
implementing SVG), I would assume that people would make more use of
SVG output, also for interactive maps. In this setup it would be
nice if one could have the option between a pure graphical output
(probably the CAIRO output version) and a more semantically rich
output (a separate output driver?) I would recommend to go with
Cairo, but leave the door open for another, alternative output
driver for more sophisticated SVG output.<br>
<br>
Regarding SWF: it would be better if Flash would die in the long run
- it is not part of the open web and a black box. All browser
project now seem committed to implement SVG and canvas. So I myself
wouldn't care if you would drop SWF support. Other users may think
different.<br>
<br>
Just my two cents,<br>
Andreas<br>

Hi all,<br>
<br>
The Dev team is reviewing and preparing for the 6.0 MapServer
release [1][2]. There are significant changes and new features
in this release. One of them is the rendering overhaul. The
reasons behind is to facilitate the long term maintenance and make
sure that all the output formats are in sync feature-wise. <br>
Currently output drivers such as svg, pdf and flash lag in
functionality and supported features compare to the AGG/GD output.
<br>
As part of this re-factoring, the Cairo library [3] will be added
allowing SVG and PDF outputs to pass through this library. This
would deprecate the current support of native svg and pdf in
MapServer.<br>
<br>
The other renderer that is affected is the SWF (Flash) renderer:
at this point there is no effort to bring this output feature to
the level of other renderers. This means that there is a big
chance that the SWF support will not be part of the 6.0 release
(unless someone wants to fund it). Is this something that affects
lots/some users?<br>
<br>
best regards,<br>
<br>
