I have a map I want to print once the user open some layers. The layers are geoserver wms and the base layer is OSM.
I know geoserver has printing module (which is installed and working because I get reply from geoserver/pdf/info.json?var=printCapabilities
What I dont understand is how I use it to print the current map with visible layers.
I've looked at GeoExt example (mapfish) but it didn't help me understand.
Update 1 : I've generated the following URL by code :
http://77.235.53.170/geoserver/pdf/print.pdf?spec={%22units%22:%22degrees%22,%22srs%22:%22EPSG:4326%22,%22layout%22:%22A4%22,%22dpi%22:%22300%22,%22mapTitle%22:%22This%20is%20the%20map%20title%22,%22comment%22:%22This%20is%20the%20map%20comment%22,%22resourcesUrl%22:%20%22http://77.235.53.170/img%22,%22layers%22:[{%22baseURL%22:%22http://77.235.53.170/geoserver/Lehavim/wms%22,%22opacity%22:1,%22singleTile%22:true,%22type%22:%22WMS%22,%22layers%22:[%22%D7%A7%D7%95%20%D7%9E%D7%99%D7%9D%22],%22format%22:%22image/jpeg%22,%22styles%22:[%22%22]}],%22pages%22:[{%22center%22:[3875254.1134954,3680894.557955],%22scale%22:32000,%22rotation%22:0}]}
and I'm getting empty PDF (only with title)... What could be wrong ?
