[OpenLayers-Users] printing highlight vector-data

[Alexandre Dubé]

Hi Jan,

   You could look at the "PrintProvider" component in the GeoExt library 
and see how they accomplish it:
   * http://www.geoext.org/lib/GeoExt/data/PrintProvider.html
   * 
https://github.com/geoext/geoext/blob/master/lib/GeoExt/data/PrintProvider.js

   Basically, what this component does is build a json file of the 
layers to print and additional details about the map (position, 
resolution, projection, etc).  Each layer has its own information for 
the server-side to be able to reproduce the same image.  For vector 
layers, the vector feature geometries are sent in addition to their 
styling.  If a feature was highlighted, its style would be added to the 
json file, then the server-side print service becomes responsible of 
reading the feature and apply each style.

   For GeoExt, the PrintProvider was designed for MapFish Print, but you 
could use your own custom server script to read what you send and apply 
the style accordingly:
     * http://www.mapfish.org/doc/print/

   So, I'd suggest you look at the PrintProvider and see how features 
and styles are saved.  You could reproduce something very similar.

Hope that helps,

Alexandre
