Hi Andrew, I was able to see the PNG image using MapGuide 2.2 build 5029. This build is a little newer than the beta but it should be similar as far as raster is concerned.
In Maestro, I specified a coordinate system override on the GDAL feature source. Then I hacked up the extents on the map definition to get the PNG image on the screen. It looks as though MapGuide does not pick up the spatial extent properly from the png but still knows where the image is. I have attached an MGP with my test files. I took a guess on the coordinate system... I also used an external data file path (alias) when building the feature source - "Gemtec" Regards, Trevor From: [email protected] [mailto:[email protected]] On Behalf Of Andrew DeMerchant Sent: August 24, 2010 10:17 AM To: MapGuide Users Mail List Subject: Re: [mapguide-users] GDAL problems... Any luck? Did my images work for you?

Now, for the images - I've tried tifs, jpgs and pngs...all with world files. None have worked. Currently, they are in png format (so I can make them transparent, once they work!). I've zipped one of the images (and world file) and put it here for now: http://www.gemtec.ca/chart_4130_a.zip Thanks for the help! I really appreciate it....I've got a plan b, if the gdal won't play nice...

If I debug and run the service interactively, I get a "(3656) An exception occurred in FDO component. Only MOSAIC(), CLIP() and RESAMPLE() are supported." message....I've seen that before, and had thought that it was coord related - but I can't even see a layer preview, and have tried the default coord system, as well the the correct one for my map. Can anyone offer some additional debug options here? My old rasters seem to still work - I just can't seem to add any new ones... -- ------------------------------------------------------------------------ GEMTEC Limited <http://www.gemtec.ca/><http://www.gemtec.ca/> *Andrew DeMerchant* tel: 506.453.1025 / toll-free: 1.877.243.6832 fax: 506.453.9470 This e-mail message (including attachments, if any) is confidential and may be privileged.
