Gamma Property (GdViewer)

In This Topic

Specifies the gamma value (gamma encoding), which represents the brightness of the displayed document in the GdViewer control.

Gamma values range from 0.1 to 5.0, usually 0.1 to 2.2. A value less than 1 lightens the image, a value of 1 leaves the image unaffected, and a value greater than 1 darkens the image.
