When you operate in DWG workmode, the following functionality is disabled by default:

• Auxiliary information — Any feature allowing to assign a logical name and description to image attachments is disabled in DWG mode.
• Images from server — Raster Manager allows the attachment of images accessible through a ModelServer Imager or Bentley Publisher server. However, access to image servers has been blocked from the Raster Manager interface when working in DWG mode.
• Display control of images — MicroStation allows to specify whether or not to display the images in a specific view port. This capability is disabled in DWG mode, so that Raster Manager will display the images in ALL views or in NO view at all.
• Independent scale factor along the x- and y-axis — When modifying an image in MicroStation, it is possible to scale it along the x- and y-axis using two different scale factors. The feature is not available in DWG mode.
• Image clipping — Raster Manager's mask clipping functionality is disabled in DWG mode.
• Tint color — When working with images in DWG workmode, all tint related tools and dialog items are disabled.
• Display gamma — The display gamma setting is made unavailable while in DWG workmode and has a default value of 1.00.
• Print gamma — The print gamma setting is also made unavailable while in DWG mode and has a default value of 1.00.
• Print control — You can control the printing of an image through a button in Raster Manager's main dialog. This feature is not available in DWG workmode.
