Thanks Jukka,<br>
<br>
I added MIMETYPE "image/png2" to my OUTPUTFORMAT and I called with
FORMAT=image/png2, and now, the PNGs are non-interlaced!<br>
<br>
I don't really understand what the difference is, but I'm glad it
works.<br>
<br>
Thanks again... now I only have to figure out why tilecache isn't
working yet...<br>

<b>Aihe:</b> [mapserver-users] mapserver produces interlaced PNGs
even if I configured the map to output noninterlaced PNGs<br>
</font><br>
</div>
Hello all, <br>
<br>
My goal is to setup tilecache (which is proving to be a real pain), and
so far I've noticed that even if I configured my map to generate
noninterlaced PNGs (instructions here: <a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://www.mapserver.org/faq.html#why-doesn-t-pil-python-imaging-library-open-my-pngs">http://www.mapserver.org/faq.html#why-doesn-t-pil-python-imaging-library-open-my-pngs</a>),
it still generates interlaced PNGs.<br>
<br>
Here is my outputformat (the only one defined) in my map:<br>
OUTPUTFORMAT<br>
NAME 'AGG'<br>
DRIVER AGG/PNG<br>
IMAGEMODE RGBA<br>
TRANSPARENT ON<br>
FORMATOPTION "INTERLACE=OFF"<br>
END<br>
<br>
The parameters that get sent to my mapserver instance are:<br>

<br>
I'm not sure if MAP_IMAGETYPE=agg is the one which selects the
outputformat or not, but the map seems to be rendered with AGG (I could
be wrong, of course).<br>
<br>
So, what am I missing here? Is there another parameter that should be
sent to mapserver to select the outputformat?<br>
<br>
By the way, the image file generated has these properties: img.png: PNG
image, 256 x 256, 8-bit colormap, interlaced<br>
<br>
Thanks,<br>
Adrian<br>
