Re: [mapguide-users] XYZ-Tiles of different size
If you know how to use/build mapguide-rest from master, I've landed a first cut implementation of "retina" xyz tiles.

Re: [mapguide-users] XYZ-Tiles of different size
That would be really cool! I'm already using mapguide-rest for consuming vector data in OpenLayers. So I think it would be easy for me to test this feature in my web application (printing solution) as soon it is available im mapguide-rest.

Re: [mapguide-users] XYZ-Tiles of different size
Assuming retina means a tile on a XYZ grid scheme whose size is [some multiple of 256 pixels]^2 then a practical short term solution would be to try and implement this in mapguide-rest first, let the feature incubate a bit and get its kinks ironed out and when it's been proven to work there, then we can port it over to MapGuide proper. mapguide-rest has proven to be a nice experimental testbed for features that have eventually made it into MapGuide (original XYZ tile support is one such example). We could do the same thing for retina XYZ tiles. - Jackie -- Sent from: http://osgeo-org.1560.x6.nabble.com/MapGuide-Users-f4182607.html ___ mapguide-users mailing list mapguide-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/mapguide-users
Re: [mapguide-users] XYZ-Tiles of different size
Hi Hans, Not exactly, since this bug, I think, refers to an external WMS service your FeatureSource is pointing to. In this case I think the MapGuide Server should have already requested the external WMS with a higher dpi value, as you mentioned, to get the result you have seen from the other server! But you are pointing in the right direction. XYZ-Tiles with a doubled size of 512 x 512 pixel should not only be resized twice. They should also have the correct label or symbol size and therefore must also be resized in relation to dpi. That's like the behaviour you have mentioned for WMS services. And I geuss that's also the reason why the GETMAPIMAGE WebApi-Methodes has a dpi value. At least I have used it with higher dpi (150) in the past for printing high quality maps.

Re: [mapguide-users] XYZ-Tiles of different size
Could it be this bug: http://osgeo-org.1560.x6.nabble.com/MapGuide-WMS-images-scaled-blurry-td5083082.html I think it has something to do with the DPI you set on your map. if you want higher resolution you need to increase the DPI from the standard 72 or 96 to 150 or 300. -- Sent from: http://osgeo-org.1560.x6.nabble.com/MapGuide-Users-f4182607.html ___ mapguide-users mailing list mapguide-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/mapguide-users
Re: [mapguide-users] XYZ-Tiles of different size
Sorry, not at the moment. XYZ tiles are currently always fixed at 256x256 pixels. If "retina" tiles is just the same bounding box rendered out to a 512x512 tile instead of 256x256, it would not be difficult to implement support for retina tiles (We can enable retina tiles via a new parameter in the XYZ TileSetDefinition). I just need confirmation around the definition of what a "retina" tile actually is. Is it just the size of the tile? Or are there other factors that make a tile "retina"? - Jackie -- Sent from: http://osgeo-org.1560.x6.nabble.com/MapGuide-Users-f4182607.html ___ mapguide-users mailing list mapguide-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/mapguide-users
