[OSGeo-Discuss] adding scalebar to images to be downloaded

[pere roca ristol]

  hi all,
  I have a webmapping application that generates map images to download in
different formats and resolutions, with the legend and so on. You can see it
in http://edit.csic.es/geo/mapviewer/edit.html or some videos
http://edit.csic.es/edit_info/edit_videos.html

  I wonder how I can add a scalebar to the image to be downloaded? as the
images to download (ImageMagick) are processed in PHP it should be a
server-side solution.

  some idea? thanks!
