A Python library and set of command line tools for extraction, parsing, and conversion of ESRI .lyr and .style files.

• RGB colors can be parsed, within a maximum of 1 unit difference in either the R/G/B components.
• Fill symbols
  • complete support for Simple Fill layers
• Line symbols
  • complete support for Simple Line layers
  • near complete support for Cartographic Line layers, including custom dash patterns. Arrows cannot be decoded yet.
• Marker symbols
  • complete support for Simple Marker layers
  • complete support for Character Marker layers

• bin_dump.py Converts a binary .style database row blob into a symbol and dumps the symbol properties to the console
• style_dump.py Dumps the complete contents of an ESRI .style database, printing symbol properties to the console
• style_to_bin.py Exports the contents of an ESRI .style database to individual .bin binary files, each containing an encoded version of a single symbol
• style_to_qgis_xml.py Converts the contents of an ESRI .style database to a QGIS 3.x Style .xml file, ready for importing direct into your QGIS style library (requires QGIS 3.x)

All tools require the command line mdbtools for handling the .style database files. Binaries of these can be downloaded from https://github.com/lsgunth/mdbtools-win, and they should be extracted and available in the Windows path.

Some description of the .style binary format can be found in specs.md, although the most up-to-date reference is the Python parsing code itself.
