Description Rolf Eike Beer 2013-03-12 18:43:46 UTC

I have created a DGML file for OSM2World. The tiles served by OSM2world are 256x128 pixels. Additionally I use hillshading which has 256x256px tiles. This doesn't work together well, it looks like something expects that all tiles have the same size. Therefore I can see jumps in the hillshading at tile borders.

Reproducible: Always

I tried the same with OpenRailwayMap, which uses 512x512 (Retina) tiles, which works equally worse (see screenshot).

Yes, this was done by design. As long as the tile layout would match we could perform some resizing on the fly. Feel free to provide a patch :) The relevant code happens inside the classes StackedTile/MergedLayerDecorator ...
