[Geomoose-users] Printing wms layers

[Jim Klassen]

GeoMoose tells the PHP what layers to print and the size and extent and scale and resolution.  The PHP code computes image size and extent (adjusting for aspect ratio of the paper) to request.  The images are requested and assembled using GD into a single image.   My guess is you hit a bug in GD.

Most of the real work is in print_util.php (if you want to add statements to log the actual requests the PHP code makes to the WMS.)

> Thanks Jim.  Yeah, I can’t understand it either- the display is perfect in the application, it’s just the print map where I have this problem.  This occurs with the pdfd, html and image options, so it’s not limited to pdf, as I originally thought.  I’ve been trying to examine the php files, but does anyone know how the map image goes from application window to print?  Apparently, not just copying the image.

>> I had brought up this question before but it seems to be happening again.  I have a few layers that I consume in GeoMoose by WMS.  Some of these are vecot line layers such as roads.  They work perfectly in GeoMoose map view.  But when I compose a printable map, these layers have a black background which obscures other layers and just plain looks ugly.  If I set the “transparent”  property to false, the black background goes away, but then I can’t see any underlying data.
