[mapserver-users] insert png image in svg output

[valerio vianello]

Hi,

so there is no way to have in output an svg file with all the layer ? because if I understood Mapserver don't support svg file in input and according to the svg spec a png file is only linked by a svg file.

Regard to the map rendering I use Firefox and if I open the svg file with firefox it works fine. The problem is the html template linked to the map. probably the issue is in the code that I use to visualize the tmp image. 
  
<td>
          <!-- THE INTERACTIVE, DYNAMICALLY CREATED MAP -->
          <input type="image" name="img" src="[img]"
                    width="600" height="400">
 </td>

Do you know what is the correct code that I have to insert in the template to visualize the svg file ?

thanks 
Valerio.

HI, 

Putting a png raster as a xlink inside svg is the correct way according to
the SVG spec. 

If I understand correctly, the SVG opens fine from the tmp dir when opened
locally, but not when pointing a browser there using http://...? Could it be
a permissions problem on the file (or more likely the tmp dir) in other
words, is the Web server allowed to serve the path mentioned in your href
(/ms4w/tmp/ms_tmp/4843c233_6948_1.png), and does it have anonymous read
rights, so the browser can pickj it up and show it..?

Also, what SVG user agent do you use: FireFox, Opera, IE with a plugin,
or...?
