Important note: Esri’s former symbology format (*.lyr) is not supported.
It is possible to generate a *.lyrx file by opening and saving your *.lyr file in ArcGIS Pro.

The plugin was built and tested on Windows using QGIS >= 3.4
Tested on Ubuntu 18.04 as well.

• Not all symbology types are currently supported, if something is missing please open an issue To use the working version of the plugin simply extract the plugin/qlyrx folder into your qgis/python/plugins folder.

On Windows installations of OSGeo4W the folder should be in:
C:\OSGeo4W64\apps\qgis-ltr\python\plugins or
C:\OSGeo4W64\apps\qgis\python\plugins or
C:\OSGeo4W\apps\qgis-ltr\python\plugins if you are using a 32bit OS

If the installation method fails for you, download the qlyrx.zip file and install the plugin using the install from zip method within the QGIS plugin manager.

• The plugin currently supports lyrx files with:

  • Unique Values symbologies (1 or 2 fields classification) => QGIS Categorized
  • Simple renderers

• Esri/Qgis main conversions:

  • CIMSolidFill => QgsSymbol.defaultSymbol
  • CIMSolidStroke (=> QgsSimpleLineSymbolLayer or base symbol stroke)
  • CIMHatchFill => QgsLinePatternFillSymbolLayer
  • CIMCharacterMarker => QgsFontMarkerSymbolLayer w QgsPointPatternFillSymbolLayer or QgsMarkerLineSymbolLayer
  • CIMGeometricEffectDashes => setCustomDashVector
  • CIMPictureFill - creates svg from base64 image string
  • CIMVectorMarker
    • CIMCharacterMarker collection
      or
    • Use predefined shapes QgsSimpleMarkerSymbolLayer w QgsMarkerLineSymbolLayer
      [Esri predefined shapes uses 'paths' WIP]

• Known issues:

  • QGIS does not offer support for grouping categories
  • SVG base64 image fill is generated as black and white image
  • Converting CIMVectorMarker from shape paths arrays to QGIS shapes is a customized tweak
  • Some lyrx symbology uses Esri's or extrnal fonts, without it, QGIS will fall back to a default font
  • Problem in converting complex CIMVectorMarker properties
  • Symbol 'halo' is not supported in QGIS (our tweak is to duplicate and enlarge the bottom most symbol, problem when using with different symbol shapes)

• Next:

  • Graduated symbology support
  • Labels support

The plugin is named qlyrx

Save your styles, after creating the new symbology with the plugin as qgis native .sld/.qml formats

To use the plugin select a .lyrx file and the layer it should style.
