I get some Messageboxes with warnings when adding a TMS [1] with GDAL minidriver: "Cannot ChunkAndWarpImage: Integer overflow: nSrcXSize=8388608, nSrcYSize=8388608" The image is completely black or just fuzzy. OTF is disabled. Can this be confirmed?

Yes, but there seems some resampling going on when requesting a CRS which the server supports (with enabled OTF): http://www.catais.org/otf_off.png http://www.catais.org/otf_on.png e.g. QGIS set to EPSG:4326 and requesting an EPSG:4326 image from a server that supports EPSG:4326. regards Stefan > -Ursprüngliche Nachricht- > Von: Radim Blazek [mailto:radim.bla...@gmail.com] > Gesendet am: Mittwoch, 9.
