:tocdepth: 3 :py:mod:`gws.plugin.qgis` ========================= .. py:module:: gws.plugin.qgis .. autoapi-nested-parse:: QGIS support. The QGIS plugin supports parsing and writing QGIS projects, stored in paths or in a Postgres database. The parsing is based on directly reading project XML files; no QGIS APIs are used. The projects are parsed into capabilities objects, from which QGIS-based layers and finders can be created. The rendering of QGIS layers is achieved by sending requests to a QGIS Server instance. Project and layer extents ------------------------- QGIS does not provide a way to obtain complete project and layer extents, with respect to symbology. Only data-based extents are known at parse time. We compute extents with the following logic: - if a project provides an explicit WMS extent (Project Properties->QGIS Server->WMS), this extent is used as project render extent (`bounds`) - otherwise, if `useCanvasExtent` is true, the canvas extent is used - otherwise, the project render extent is set to the union of layers' data extents + the configured `extentBuffer` - if the render extent is empty, the CRS extent is taken - for layers, the data extent is either an explicit extent (Layer Properties->Metadata->Extent) or an implicit data extent - the layer data extent is used as a "zoom" extent, but when rendering a layer, the project extent is used **Source code:** :source:`gws.plugin.qgis` Submodules ---------- .. toctree:: :titlesonly: :maxdepth: 1 caps/index.rst cli/index.rst finder/index.rst flatlayer/index.rst layer/index.rst legend/index.rst model/index.rst project/index.rst provider/index.rst template/index.rst
