I also had some problems recently with rendering rasters in Mapnik with the GDAL-plugin. With mapnik2 I got a segfault (but am not completely sure if that happened because of the rasters). Then I went back to mapnik 0.7.2 and I noticed that apparently rasters which you render with opacities not equal to 1 (i.e. partly transparent) were omitted when using the C-bindings (tirex-mapnik-backend) but rasters with opacity=1 were rendered. The same stylesheet produced completely valid results also for semi-transparent input layers when it was rendered with the python bindings (generate_image/tiles.py).
Currently I am verifying if this is an issue of the tirex-implementation or a general problem with the c-bindings. cheers, Martin _______________________________________________ Mapnik-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/mapnik-users
