I need to generate tiles from shape files (which contain contour lines) I've loaded into QGIS. I'm trying to use the QTiles plugin to generate these tiles, but when I run it, it only generates blank tiles.
Following settings used: Output: Directory Extent: Canvas Extent Zoom: 10 - 12 Quality: Use TMS tiles convention
It almost looks like the canvas extent has not been selected properly? It seems like I'm missing something small. Possibly a decent tutorial will also help. I'm new to QGIS and I'm using 2.8.3-Wein on Ubuntu.
I've tried generating tiles with the natural earth oceans vector and it seems to work fine.
