シンボル仕様 / Symbol Specification

日本語

  • QGIS Symbol -> JSON への変換仕様を定義します
  • QGISの1レイヤーには1個以上のSymbolLayerが含まれます
  • 通常は1SymbolLayer=1Symbolですが、一部特殊なSymbolLayerは複数のSymbolを含むことがあります（例：FilledMarker）
  • ひとつのSymbolLayerは、ひとつのシェープファイルに対応します

English

  • Defines the conversion rules from QGIS Symbols to JSON.
  • Each QGIS layer contains one or more SymbolLayers.
  • Usually, 1 SymbolLayer = 1 Symbol, but some special SymbolLayers may include multiple Symbols (e.g., FilledMarker).
  • Each SymbolLayer corresponds to one shapefile.
