"Output" group is used to select output type: as directory structure or as ZIP-archive. Tiles themselves are saved in PNG format.
Group «Extent» allow to set desired geographic extent of the map. You can select one of the following options:
- Canvas extent — current canvas extent will be used
- Full extent — full extent of all project layers will be used
- Layer extent — output extent will be the same as extent of the selected layer
In «Zoom» group one can set zoom levels. In most cases maximum zoom 18 is enough, but plugin can generate tiles for "deeper" zoom levels. "Depth" depends on the map detalization on certain scales.
"Parameters" group is used to define tile size. Supported values are 128 - 2048 pixels per side.
Press "ОК" to start tile generation and "Cancel" to terminate it.
