v0.20.1

New Functionality

• Wireframe mode for debugging #745
  • Use debug option wireframe: true to draw geometry in a wireframe mode, helpful for seeing how Tangram converts feature geometries into renderable GL triangles, and debugging issues with such
  • Example of enabling wireframe mode when the Tangram layer is created:

  const layer = Tangram.leafletLayer({
    scene: 'scene.yaml',
    debug: {
      wireframe: true // enable for wireframe rendering mode
    }
  });
  

Bug Fixes

• Fix inconsistencies in handling of line dash colors and alpha #741 #742
  • Alpha of dash foreground and background colors should not affect each other
  • More consistent handling of alpha cutout behavior for opaque blending
• Remove spurious errors when an untiled data source is drawn with the all_layers flag set #747 77b9edb

Internal

• Upgrade geojson-vt to v3.2.1
