[mapguide-users] White tiles at z = 0

[Jackie Ng]

Hi Gunter,

Thank you for providing an updated test mgp with vector data.

I can see the problem locally for the vector layer which gives me more
confidence that it is a Rendering/Stylization level regression that I can
dig into and I am willing to hold off on the Beta 1 release in order to
address this issue.

Thanks,

- Jackie

Hi Jackie,

so, I have to correct myself. The tiles aren’t white but transparent.
Here is an example of a request at z=0:
https://stadtplan.badoeynhausen.de/mapguide4.0/mapagent/mapagent.fcgi?USERNAME=Anonymous&OPERATION=GETTILEIMAGE&VERSION=1.2.0&CLIENTAGENT=OpenLayers&MAPDEFINITION=Library%3A%2F%2FBOGIS%2FKarten%2FRaster%2FBasiskarte%2FBasemap_farbig.TileSetDefinition&BASEMAPLAYERGROUPNAME=Basemap_farbig&TILECOL=31729&TILEROW=49461&SCALEINDEX=0

and a request with z=1:
https://stadtplan.badoeynhausen.de/mapguide4.0/mapagent/mapagent.fcgi?USERNAME=Anonymous&OPERATION=GETTILEIMAGE&VERSION=1.2.0&CLIENTAGENT=OpenLayers&MAPDEFINITION=Library://BOGIS/Karten/Raster/Basiskarte/Basemap_farbig.TileSetDefinition&BASEMAPLAYERGROUPNAME=Basemap_farbig&TILECOL=12693&TILEROW=19784&SCALEINDEX=1

Or you can see it here in our OpenLayers-Viewer:
https://stadtplan.badoeynhausen.de/Viewer?Map=90ebac7f-bbd0-4e6b-98d8-2e5985d0bfd1

Just zoom in to 1:100 (z=0).

I have filed an additional MapGuide Package to the ticket that
includes vector data (SDF) and MapDefinitions with inline tiles.
All MapDefinitions produce incorrect tiles at z=0. I double checked
this on MapGuide Server 3.1.2.

Thanks, Gunter
