About Raster Images in Drawings

Raster images consist of a rectangular grid of small squares or dots known as 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, document management,
engineering, mapping, and geographic information systems (GIS). Images can be bitonal,
8-bit gray, 8-bit color, or 24-bit color. Images with 16-bit color depth are not supported.

Several image file formats support images with transparent pixels. When image transparency
is set to on, the program recognizes those transparent pixels and allows graphics
in the drawing area to “show throughâ€‌ those pixels. (In bitonal images, background
pixels are treated as transparent.) Transparent images can be gray-scale or color.

NOTE:

Although the file name extension is listed in the following table, the file format
is determined from the file contents, not from the file extension.

Use the Ribbon Contextual Tab to Work with Raster Images

If you select an image when the ribbon is active, the Image Ribbon Contextual tab
displays. The contextual tab contains options for adjusting, clipping and displaying
images. The ribbon contextual tab is dismissed automatically after the image is deselected.
