#### Migrate from Leaflet.PM

``
npm uninstall leaflet.pm
npm i @geoman-io/leaflet-geoman-free
`
That's it.

#### Install via npm

`
npm i @geoman-io/leaflet-geoman-free
`

#### Install Manually

Download
leaflet-geoman.css and
leaflet-geoman.min.js
and include them in your project.

#### Include via CDN

CSS


`html


`

JS

`html

`

#### Include as ES6 Module

`js
import '@geoman-io/leaflet-geoman-free';
import '@geoman-io/leaflet-geoman-free/dist/leaflet-geoman.css';
`

#### Init Leaflet-Geoman

Just include leaflet-geoman.min.js right after Leaflet. It initializes itself. If
you want certain layers to be ignored by Leaflet-Geoman, pass pmIgnore: true to
their options when creating them. Example:

`js
L.marker([51.50915, -0.096112], { pmIgnore: true }).addTo(map);
`

Enable Leaflet-Geoman on an ignored layer:
`js
layer.setStyle({pmIgnore: false});
// layer.options.pmIgnore = false; // If the layer is a LayerGroup / FeatureGroup / GeoJSON this line is needed too
L.PM.reInitLayer(layer);
`
If Opt-In (look below) is true, a layers pmIgnore property has to be set to false to get initiated.

#### Opt-In

If you want to use Leaflet-Geoman as opt-in, call the following function right after importing:

`js
L.PM.setOptIn(true);
`

And to disable it:

`js
L.PM.setOptIn(false);
`

If you have enabled opt-in before you init the map, you need to specify pmIgnore: false in the map options:

`js
const map = L.map('map', { pmIgnore: false });
`

All layers will be ignored by Leaflet-Geoman, unless you specify pmIgnore: false on a layer:

`js
L.marker([51.50915, -0.096112], { pmIgnore: false }).addTo(map);
`

Newly drawn layers will be ignored as well.

To prevent this you can add the following event handler:

`js
map.on('pm:create', (e) => {
e.layer.setStyle({ pmIgnore: false });
L.PM.reInitLayer(e.layer);
});
`

#### Leaflet-Geoman Toolbar



You can add a toolbar to the map to use Leaflet-Geoman features via a user interface.

`js
// add Leaflet-Geoman controls with some options to the map
map.pm.addControls({
position: 'topleft',
drawCircle: false,
});
`
The following methods are available on map.pm:

| Method | Returns | Description |

map.pm.enableDraw('Polygon',{ snappable: false });
map.pm.disableDraw();
`
`js
// make all layers not snappable during draw
map.pm.setGlobalOptions({ snappable: false });
`
The options will persist, even when the mode is enabled/disabled via the toolbar.

All available options for drawing and editing are specified in the sections below.

| pm:create | e | Called when a shape is drawn/finished. Payload includes shape type and the drawn layer. | shape, layer |

There are also several events for layers during draw. Register an event like this:

`js
// listen to vertexes being added to currently drawn layer (called workingLayer)
map.on('pm:drawstart', ({ workingLayer }) => {
workingLayer.on('pm:vertexadded', (e) => {
console.log(e);
});
});

You can enable Scale Mode for all layers on a map like this:

`js
map.pm.enableGlobalScaleMode();
`

With the option centerScaling the scale origin cen be the center of the layer or the opposite corner of the dragged marker. If false Alt-Key can be used.
The option uniformScaling the scales the width and the height with the same ratio. If false Shift-Key can be used.

The following methods are available on map.pm:

| Method | Returns | Description |
| :----------------------- | :-------- | :--------------------------------------------------------------------- |
| enableGlobalScaleMode() | - | Enables global Scale Mode. |
| disableGlobalScaleMode() | - | Disables global Scale Mode. |
| toggleGlobalScaleMode() | - | Toggles global Scale Mode. |
| globalScaleModeEnabled() | Boolean | Returns true if global Scale Mode is enabled. false when disabled. |

The following methods are available for layers under layer.pm:

| Method | Returns | Description |
| :-------------------- | :-------- | :---------------------------------------------------------------------------------------------------------------------------- |
| enableScale() | - | Enables Scale Mode on the layer. |
| disableScale() | - | Disables Scale Mode on the layer. |
| scaleEnabled() | Boolean | Returns if Scale Mode is enabled for the layer. |
| scaleLayer(percent) | - | Scale the layer by x percent. Also an Object with {w: width, h: height} can be passed. Scale up > 0 , scale down < 0. |

The following events are available on a layer instance:

| Event | Params | Description | Output |
| :-------------- | :----- | :---------------------------------------- | :----------------------------------------------------- |
| pm:scaleenable | e | Fired when scale is enabled for a layer. | layer, helpLayer |
| pm:scaledisable | e | Fired when scale is disabled for a layer. | layer |
| pm:scalestart | e | Fired when scale starts on a layer. | layer, helpLayer, originLatLngs, originLatLngs |
| pm:scale | e | Fired when a layer is scaled. | layer, helpLayer, oldLatLngs, newLatLngs |
| pm:scaleend | e | Fired when scale ends on a layer. | layer, helpLayer, originLatLngs, newLatLngs |

The following events are available on a map instance:

| Event | Params | Description | Output |

You have many options available when drawing and editing your layers (described above).
You can set the options per layer as described above, or you can set them globally for all layers. This is especially useful when you use the toolbar and can't change the options programmatically.

Examples:

`js
layer.pm.enable({ pinning: true, snappable: false });
`

`js
map.pm.setGlobalOptions({ pinning: true, snappable: false });
`

The following options are additionally to the Draw and Edit Mode options.

| Option | Default | Description |
| :------------ | :------- | :--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| snappingOrder | Array | Prioritize the order of snapping. Default: ['Marker','CircleMarker','Circle','Line','Polygon','Rectangle']. |
| layerGroup | map | add the created layers to a layergroup instead to the map. |
| panes | Object | Defines in which panes the layers and helper vertices are created. Default: { vertexPane: 'markerPane', layerPane: 'overlayPane', markerPane: 'markerPane' }. |

Some details about a few more powerful options:

##### 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

##### Pinning ⭐

When dragging a vertex/marker, you can pin all other Markers/Vertices that have the same latlng to the dragged marker. Exclusive for Leaflet-Geoman Pro ⭐

!Pinning Option

##### Measurement ⭐

!Measurement Demo

Calculates the measurement of a layer while drawing and editing. Exclusive for Leaflet-Geoman Pro ⭐

`js
map.pm.setGlobalOptions({ measurements: { measurement: true, displayFormat: 'metric', ... } })
`

See the available options in the table below.

| Option | Default | Description |
| :----------------- | :------- | :-------------------------------------------------------------------------------------------------------------------- |
| measurement | true | Enable measurement calculation. |
| showTooltip | true | Shows the tooltip during draw and edit. |
| showTooltipOnHover | true | Shows the tooltip when hovering a finished layer. |
| displayFormat | metric | Displayed format in the tooltip metric or imperial. |
| totalLength | true | Shows the total length in the tooltip Line. |
| segmentLength | true | Shows the segment length in the tooltip Line, Polygon. |
| area | true | Shows the area in the tooltip Polygon, Rectangle, Circle, CircleMarker. |
| radius | true | Shows the radius in the tooltip Circle, CircleMarker. |
| perimeter | true | Shows the perimeter in the tooltip Polygon, Rectangle, Circle, CircleMarker. |
| height | true | Shows the height in the tooltip Rectangle. |
| width | true | Shows the width in the tooltip Rectangle. |
| coordinates | true | Shows the coordinates in the tooltip Marker, CircleMarker and the current dragged marker while drawing / editing. |

Leaflet-Geoman can only work correct with L.FeatureGroup and L.GeoJSON (the extended versions of L.LayerGroup) we need the events layeradd and layerremove.

The following methods are available for LayerGroups on layergroup.pm`:
