Image is bitonal

What does bitonal mean? I was trying to adjust a raster image in AutoCAD 2008 by using the IAD command.

 

Select image(s):

Bitonal images cannot be adjusted.

 

Any ideas other than adjusting it in another program?

Bitonal images are monocrhromatic black and white only with no shades of grey.

 

To adjust the image in Autocad, the image needs to be either greyscale or color. You could use Photoshop, Gimp, or programs along those lines to convert the image to greyscale.
