[OpenLayers-Users] OpenLayers.Control.Swipe

[Gabriel Vatin]

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
