[mapserver-users] PPH Mapscript - limit to number of shape objects in a layer?

[Alan Hale]

Hi Alan

Thanks for the reply. I'm displaying the map image via Overlib and so 
not getting any error messages- just no image. I know the limit is 11528 
just by setting LIMIT on the database query and iterating to the max 
value. I've been trying to debug the script that generates the image but 
this is proving more difficult than I thought since various parameters 
are passed via Overlib so I will have to insert some dummy values.

Hope to get back with more information later.

Regards

Alan
