To Change the Image Mask Properties for a New Mask

1. On the ribbon, click Raster Tools tab Manage & View panel (expanded) Create Mask.
2. You can clear the Enable Mask check box if you want to disable (turn off) a mask. When the mask is disabled, you can still edit the mask boundary, but the images are not affected until you enable the mask again. Only one mask in model space or paper space can be enabled at a time. For more information, see Enabling or Disabling a Mask.
3. Choose one of the following mask options:
   • Do Not Affect
   • Hide Image(s)
   • Unload Images
4. Select the Show Image Frame(s) check box if you want to show the frames of the images that are outside the mask object. This option is available only if the Hide Image(s) or Unload Image(s) option is selected.
   Note: If you used the AutoCAD IMAGEFRAME command to turn off image frames in your drawing, then the Show Image Frame(s) check box is unavailable and you cannot show the image frames.
5. Click Close to save your changes.
