Hi Cédric,
Thank you for this amazing control ! Yet I have a few questions about it :
- in you examples, you use OpenLayers 2.13 (dev branch of OL). I tried
it with my local copy of OL, the 2.11 version, and the 2.12 version, but
I still have the same error : /this.map.layerContainerOriginPx is undefined/
Have you tried it with these versions of OL ?
- I don't really undestand which layers it shows / hide : is it all the
visible layers on the left side, and just the base layer on the right
side, or can we select the layers to hide ?
Thanks for this !
Gabriel

Hi,
A pure OpenLayers example can be shown here:
http://mf-chsdi0i.bgdi.admin.ch/main/wsgi/GeoAdmin.ux/Swipe/examples/openlayers_swipe.html
The source code is here:
http://docs.google.com/uc?export=download&id=0B_gmqEgDEiu5WGRGVDRQd281UVE
<http://docs.google.com/uc?export=download&id=0B_gmqEgDEiu5WGRGVDRQd281UVE>
Swipe can be used in the following way:
var map = new OpenLayers.Map("map");
var ol_wms = new OpenLayers.Layer.WMS(
"OpenLayers WMS",
"http://vmap0.tiles.osgeo.org/wms/vmap0";,
{layers: "basic"}
);
var dm_wms = new OpenLayers.Layer.WMS(
"Canadian Data",
"http://www2.dmsolutions.ca/cgi-bin/mswms_gmap";,
{
layers: "bathymetry,land_fn,park,drain_fn,drainage," +
"prov_bound,fedlimit,rail,road,popplace",
transparent: "true",
format: "image/png"
},
{isBaseLayer: false, visibility: true}
);
map.addLayers([ol_wms, dm_wms]);
var swipe = new OpenLayers.Control.Swipe({map: map});
map.addControls([new OpenLayers.Control.LayerSwitcher(),swipe]);
swipe.activate();
map.zoomToMaxExtent();
Swipe control works also on mobile.
Hope this helps,
Cédric
