[GIS] Setting background RGB value to invisible for multiple rasters in ArcGIS Desktop

arcgis-10.0arcgis-desktoprastersymbology

I'm using ArcGIS Desktop 10.0.

I need to set my background rgb value of 255,255,255 to transparent. In the layer-Properties Windows > Symbology I can do it for one layer, but can I batch set this, or use arcpy? I have to do it for around 300 layers.

Best Answer

It seems that I can do it for an mxd document by going to :

Tools > ArcMAP-Options > Raster > RasterLayer > Background value

All Raster layers that are then subsequently added will receive the defined background color.
