Attach Raster Image Files
You can view and manipulate raster images and associated file paths in drawings.
You can add raster images to your vector-based drawings, and then view and plot the resulting file. There are a number of reasons for combining raster images with vector files, including scanning documents, faxes, or microfilm drawings; using aerial and satellite photographs; using digital photographs; creating effects such as watermarks and logos; and adding computer-rendered images.
You can add or remove references to raster images within drawing files, or you can change their relative size.
You can control the clipping boundaries and image display properties of a raster image.
You can view and manipulate raster images and change paths to image files using the External References palette.
You can reduce the demands on system performance when manipulating large or many small raster images.
