[mapserver-users] mapscript php with agg rendering?

[Michael Schulz]

Jean-Francois,

you saved my day :-) That got it working...

I definitely think there is something wrong when trying to create an
outputformat with php/mapscript from scratch. I'll try to narrow this
down a bit and maybe open the mentioned ticket again.

Thanks, Michael
