We use "VPraster" from http://www.softelec.com. That's a software to import and edit raster files (tif, bmp, jpg, ..) in AutoCAD. The raster data is stored in the dwg-file, included in some dictionaries. To display this so called "hybrid data" in a standard AutoCAD, you have download and install the free software "RasterDWG Drivers" from Softelec - Support - Drivers.
What to you think about an integration of this arx-function into your viewer? To you think it is possible or not?
