I am trying to make an application that creates geospatial pdf's from my website, but I am encountering problems with Gdal_translate and transparency of rasters.
The setup that I am working up against is based on Mapserver, creating wms services. These services are created with image/png properties, and a predefined transparency.I would like to be able to combine these wms serices on top of a basemap in a geospatial PDF, but when I combine the layers with Gdal_translate, the transparency on the individual layers are lost.
When I call the layers individually with Gdal I am quite sure the transparency is present, so I assume that the problem occurs in the process of making the overlays in Gdal.
Have anybody experimented with this usage of gdal_translate against Mapserver - and have succeded in creating transparent overlays from rasters?
