Hi,<br>
I'm using MapServer 4.99 and trying to modify the processing directive
for a raster layer dynamically using a CGI parameter. I want to let the
user modify the min and max values used to scale the image. I've tried
lots of different syntaxes for this without any success. Anybody know
the trick? I've tried the following:<br>
<br>
&amp;map_layername_processing="scale=15000,17000"<br>
&amp;map_layername_processing="scale%3D15000%2C17000"<br>
&amp;map_layername_processing=scale%3D15000%2C17000<br>
&amp;map_layername_processing_0=<i>all of the above...</i><br>
&amp;map_layername_processing_scale=15000,17000<br>
&amp;map_layername_processing_scale=15000%2C17000<br>
&amp;map_layername_processing_scale=15000+17000<br>
&amp;map_layername_processing_0_scale=<i>all of the above...</i><br>
<br>
Is this something that's not possible to modify dynamically? Thanks for
any help!<br>
Best Regards,<br>
