[OpenLayers-Users] Swipe

[Arnd Wippermann]

Hi,

Perhaps the following example points in a useable direction:
http://gis.ibbeck.de/ginfo/apps/OLExamples/OL27/examples/ExternalGraphicOver
lay/ExternalGraphicOverlay.asp

I use a pointFeature styled with ExternalGraphic as Image Layer. With the
style options one can change the image width, height and rotation. And the
image is dragable through the DragFeature Control.

Arnd

Hi, the second option... still 100% opacity, the slider would modulate the
width (by the right edge)
