leaflet-easyprint-bbox

A simple leaflet plugin which adds an icon to print or export a map.

This fork of rowanwins/leaflet-easyPrint concentrates on the mapbounds and the dpi to export.

Features

• Supports resizing to predefined sizes (A4 Landscape & Portrait) as well as custom sizes
• Supports saving to png, as well as printing
• Compatible with both Leaflet v1+ and 0.7
• Tested on Chrome, Firefox
  • Incompatible with IE & Edge due to dom-to-image dependency

Check out the demo.

Download

You can either download this repo directly or install via NPM.

npm install leaflet-easyprint-bbox

Options

You can pass a number of options to the plugin to control various settings.

| Option | Type | Default | Description | | ------------- |--------------|--------------|---------------| | title | string | 'Print map' | Sets the text which appears as the tooltip of the print/export button | | position | Leaflet control position | 'topleft' | Positions the print button | | sizeModes | array | Current | Options available include Current, A4Portrait, A4Landscape or a custom size object | | defaultSizeTitles | object | {Current: 'Current Size', A4Landscape: 'A4 Landscape', A4Portrait: 'A4 Portrait'}| button tooltips for the default page sizes | | exportOnly | Boolean | false | If set to true the map is exported to a png file | | tileLayer | Leaflet tile layer | null | A tile layer that you can wait for to draw (helpful when resizing) | | tileWait | Integer | 500 | How long to wait for the tiles to draw (helpful when resizing) | | filename | string | 'map' | Name of the file if export only option set to true | | hidden | Boolean | false | Set to true if you don't want to display the toolbar. Instead you can create your own buttons or fire print events programmatically. You still need to call addTo(map) to set the leaflet map context. | | hideControlContainer | Boolean | true | Hides the leaflet controls like the zoom buttons and the attribution on the print out. | | hideClasses | array | [] | Hides classes on the print out. Use an array of strings as follow : ['div1', 'div2'] | | customWindowTitle | string | Defaults to title of map window. | A title for the print window which will get added the printed paper. | | spinnerBgColor | string | '#0DC5C1' | A valid css colour for the spinner background color. | | customSpinnerClass | string | 'epLoader' | A class for a custom css spinner to use while waiting for the print. | | dpi | Integer | 300 | This value is for calculating the correct export pixel resolution |

Example

L.easyPrint({
    dpi: 600,
    [...]
}).addTo(map);
