Parallel tile rendering for QGIS3

Use QGis Script runner plugin to run render_tiles5.py

Scipt uses fixed metatiling scheme, so metatile bounds are always the same independed of export bounds. This helps to fix some cut labels or cut symbols, which may appear at metatile bounds.

Usage

The selected object will be used for export bounds. You can edit render_tiles5.py to alter script behaviour. Tiles will be 256x256 24 bit PNG

  • minzoom - minnimum zoom level for export. Default 0

  • maxzoom - maximum zoom level for export. Default 15

  • threads - number of threads to use. Default 8

  • meta - metatile level 2 = 4x4 tiles, 3 = 8x8 tiles, 4 = 16x16 tiles and so on. Default 8

  • fileInfo - directory to store tiles
