Hi Ben, GeoExt is using OpenLayers as well and is just an additional layer on top of Ext-JS (for the interface components) and OpenLayers (for the mapping components). Therefore I think it wouldn´t be much extra-effort. You can just use your existing OpenLayers-code with your map-object. Instead of rendering this map-object directly to a div-container like you would usually do, you create a GeoExt-mappanel (http://geoext.org/lib/GeoExt/widgets/MapPanel.html) based on this. This mappanel is then used to create the GeoExt-PrintProvider (http://geoext.org/lib/GeoExt/data/PrintProvider.html) which you may then use for implementing the print-functionality. This enables the print-provider to get the currently activated layers and bounding-box from the map. Several examples of implementing this functionality are provided here (though the examples don´t seem to work currently but the scripts are still available): http://geoext.org/examples.html. What you will use of that depends on your intended functionality.
Cheers and good luck with the implementation, Max Von: Stephen V. Mather [mailto:s...@clevelandmetroparks.com] Gesendet: Dienstag, 28.

Hi Ben, Writing clients for mapfish is not hard. I don't have any OL examples to share, but you just need to PUT a specially formatted json to the service endpoint-- the json doc declares layers, extent, dpi, layout, etc. I don't know how well the API is documented these days, but some hints can be found here: https://smathermather.wordpress.com/category/gis/mapfish/ Best of luck, Steve [http://sig.cmparks.net/cmp-ms-90x122.png]Stephen V.

Dear colleagues, I have a couple of OpenLayers apps (backed by Geoserver) to which I'd like to add the ability to print the map in .pdf format. The Geoserver Printing Module (http://docs.geoserver.org/latest/en/user/community/printing/index.html) looks like it would provide the server-side support I'm looking for. However, the documentation for the Print Module indicates that the print service it supports is meant to be used from GeoExt client-side apps. For a variety of reasons (not the least of which is budget limitations) I'm not in a position to re-implement the OL apps in question using GeoExt. Given this, I have a couple of questions: 1. Does anyone know if a plain-vanilla OpenLayers app can successfully make use of the Geoserver Printing Module service? If anyone does, I'd appreciate reference(s) to working sample code. 2. If (1) is not possible, is there some approach that would work that wouldn't require re-writing the whole app to use GeoExt? For example, might it be possible to use GeoExt only in a very limited way (e.g., manage the 'map canvas') and rely on the existing body of OL code to handle everything else (e.g., manage on-screen controls, generation/display of legends, etc.) and still be able to exploit the Print Module? If the answer is 'yes', pointers to sample working code would be appreciated. Since the answer to these questions might be found in either the GeoSever or OpenLayers communities, I'm posting this inquiry to both mailing lists. My apologies if you receive these questions twice. Thanks in advance for any help you can offer with this.
