Split Mode

Split Mode allows you to draw a line that splits all underlying Polygons and Lines. When a feature is split, the original feature will be replaced with the resulting split features.

You can handle Split Mode for all layers on a map like this:

map.gm.enableMode('edit', 'split');
map.gm.disableMode('edit', 'split');
map.gm.toggleMode('edit', 'split');
map.gm.isModeEnabled('edit', 'split');

The following methods are available on map.gm:

Method	Returns	Description
enableMode('edit', 'split')	-	Enables global Split Mode.
disableMode('edit', 'split')	-	Disables global Split Mode.
toggleMode('edit', 'split')	-	Toggles global Split Mode.
isModeEnabled('edit', 'split')	Boolean	Returns true if global Split Mode is enabled. false when disabled.

The following events are available on a map instance:

Event	Params	Description	Output
gm:split	event	Fired during the split operation.	map, originalFeature, features
gm:create	event	Fired during the split operation.	map, feature, shape

The following events are available on a map instance:

Event	Params	Description	Output
gm:globalsplitmodetoggled	event	Fired when Split Mode is toggled.	enabled, map

You can also listen to specific Split Mode events on the map instance like this:

map.on('gm:globalsplitmodetoggled', (event) => {
  console.log(event);
});

Behavior

Split mode operates by:

1. Drawing a line across features you want to split
2. The line will split any intersecting polygons or lines into separate features
3. Original features are replaced with the resulting split features
