Snapping

Snapping​

Snap the dragged marker/vertex to other layers for precision drawing.
Snapping can be disabled for layers with the layer option snapIgnore: true. With snapIgnore: false it will be always snappable, also if pmIgnore is set. Can also be disabled by holding the ALT key.

Snapping Options

Configuration​

Snapping is disabled by default. You can enable snapping by setting snappable to true in the global options.

map.pm.setGlobalOptions({ 
  snappable: true, 
});

You can get the current snappable status by calling map.pm.getGlobalOptions().snappable.

or by destructuring the snappable property from the global options.

const { snappable } = this.map.pm.getGlobalOptions()

Snapping Button in the Toolbar​

You can also enable/disable a button in the toolbar to toggle snapping. You can enable (disable) it by setting snappingOption to true (false) in the addControls options.

map.pm.addControls({ 
  snappingOption: true, 
});
