hi All,
I'm in big troubles with a wierd error in python mapscript, the log
reports: libpng error: image size exceeds user limits in IHDR
image size is 256x256... using gif instead of png shows no errors (as
expected)... any idea?
the very same piece of code run fine on my testing machine, the error
is only on production server.
Mapserver version is 6.0.3, python 2.5 and the code is basically a
wrapper to WMS service, the error appears just after
map.OWSDispatch( req )
output format is set to AGGA:
OUTPUTFORMAT
NAME 'AGGA'
DRIVER AGG/PNG
IMAGEMODE RGBA
END
the complete call is
?LAYERS=track_1&TRANSPARENT=TRUE&FORMAT=image%2Fpng%3B%20mode%3D24bit&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A900913&BBOX=0.0,5009377.0857,2504688.54285,7514065.62855&WIDTH=256&HEIGHT=256
It seems like wrong HEIGHT and WIDTH are passed to the raster buffer,
I've already checked that the map object has the right size after
OWSDispatch.
Thanks in advance for any help!
