[OpenLayers-Users] Image without dithering after zoom

[Andreas Hocevar]

You can specify a tile class on a per-layer basis, using the className
layer option: http://dev.openlayers.org/releases/OpenLayers-2.12/doc/apidocs/files/OpenLayers/Layer/Grid-js.html#OpenLayers.Layer.Grid.className

With this you can define these image rendering options only for specific layers.
