Change Raster Image Brightness, Contrast, and Fade
You can change several display properties of raster images in a drawing for
easier viewing or special effects.
You can adjust brightness, contrast, and fade for the display of an image as
well as for plotted output without affecting the original raster image file and
without affecting other instances of the image in the drawing. Adjust brightness
to darken or lighten an image. Adjust contrast to make poor-quality images
easier to read. Adjust fade to make drawing geometry easier to see over images
and to create a watermark effect in your plotted output.
Bitonal images cannot be adjusted for brightness, contrast, or fade. Images
fade to the current screen background when displayed, and they fade to white
when plotted.
