Printing an Area

[fobetor]

Hello
I would like to know, if it may be possible to tell this print module to print an area (I am using the Area Select plugin), not just the full map, but themap inside the area.
It may be interesting (similar as what geoext does)

Thanks in advance
Fernando

Hi, sorry for the late reply. Mapfish uses the bbox parameter to specify the print area. By default the print provider calculates the print and scale parameters and sends those:

var jsonData = JSON.stringify(L.extend({
			units: L.print.Provider.UNITS,
			srs: L.print.Provider.SRS,
			layout: options.layout,
			dpi: options.dpi,
			outputFormat: options.outputFormat,
			outputFilename: options.outputFilename,
			layers: this._encodeLayers(this._map),
			pages: [{
				center: this._projectCoords(L.print.Provider.SRS, this._map.getCenter()),
				scale: this._getScale(),
				rotation: options.rotation
			}]
		}, this.options.customParams, options.customParams, this._makeLegends(this._map)))

You could try setting the bbox in the pages configuration through customParams.

Thank you

Hello again Adam
Another question: Is there a way of changing the projection srs?
I see it is defined as EPSG:3857 but if I change this and try touse the EPSG:27700 it throws an error?
I cant find where it looks for the projexction definitions...
Thank you

It's referencing the property L.print.Provider.SRS. I would try setting that immediately after you load the library e.g.

<script>
L.print.Provider.SRS = 'EPSG:27700';
</script>
