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.

pixels. For example, a photograph of a house is made up of a series of pixels
colorized to represent the appearance of a house. A raster image references
the pixels in a specific grid.
Raster images, like many other drawing objects, can be copied, moved, or
clipped. You can modify an image with grip modes, adjust an image for
contrast, clip the image with a rectangle or polygon, or use an image as a
cutting edge for a trim.
The image file formats supported by the program include the most common
formats used in major technical imaging application areas: computer graphics,
