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.
Modify Color and Transparency for Bitonal Raster
Images
Bitonal images are images that consist only of a foreground color and a
background color. You can change the foreground color and turn the
transparency of the background color on and off.
Bitonal raster images are images consisting only of a foreground color and a
background color. When you attach a bitonal image, the foreground pixels
in the image inherit the current settings for color. In addition to the
modifications you make to any attached image, you can modify bitonal images
by changing the foreground color and by turning on and off the transparency
of the background.
NOTE Bitonal images and their boundaries are always the same color.
