Command : ImageAdjust 

Menu : Modify > Object > Image > Adjust 

-Controls the Brightness, Contrast and Fade value of Selected Image.

Brightness

Controls the brightness, and indirectly the contrast, of the image. The greater the value, the brighter the image and the more pixels that become white when you increase contrast.

Contrast

Controls the contrast, and indirectly the fading effect of the image. The greater the value, the more each pixel is forced to its primary or secondary color.

Fade

Controls the fading effect of the image. The greater the value, the more the image blends with the current background color. A value of 100 blends the image completely into the background. Changing the screen background color causes the image to fade to the new color. In plotting, the background color for fade is white.

Image Preview

Displays a preview of the selected image. The preview image updates dynamically to reflect changes to the brightness, contrast, and fade settings.

Reset

Resets values for brightness, contrast, and fade to default settings (50, 50, and 0, respectively).

ImageFrame

Value 0 : if the border should be completely removed

Value 1 : if the border should be displayed, but not printed

Transparency

Change the Transparency Mode ON or OFF.

ON : Transparent the Raster Image. Set Transparency Value between 0-90.

         (TPY button on status bar should be ON)

OFF : Opaque the Raster Image.
