Re: [mapserver-users] A couple of mapcache questions
For my example below the mapfile has: TRANSPARENT TRUE IMAGECOLOR 181 181 181 and mapcache.xml has: http://maps2.dnr.state.mn.us/cgi-bin/mapserv64? dummy false PNG24 LAKEFINDER_TILES_MAPFILE lakefinder_wms mn_google disk PNGQ_FAST 8 8 20 My mn_google grid is just the standard Google grid mapcache defines along with a limited extent. --Steve -Original Message- From: Robert Miller [mailto:robert.mil...@floodbroker.com] Sent: Wednesday, October 10, 2018 11:40 AM To: Lime, Steve D (MNIT) ; mapserver-users@lists.osgeo.org Subject: Re: [mapserver-users] A couple of mapcache questions Thanks very much for your reply.

Re: [mapserver-users] A couple of mapcache questions
Thanks very much for your reply. I actually worked #1 out - I had the wrong units set in the grid. I'm only using the style in the .map file, and haven't set min and max scale at this point. Linecolor and width are (I think) sufficient, since it's just drawing a grid.

Not sure if others replied off-list or not. It's hard to advise on issue 1 since the mapfile and layer definition you sent in the subsequent email was incomplete.
