#!N  #!Rtall719 DXHWGAMMA #!N sets the gamma correction for 
hardware-rendered images displayed to the screen by a Display or Image 
tool. On many display devices a given change in the digital 
brightness of the image is not reflected in a corresponding change 
in screen brightness. A gamma correction is a non-linear adjustment of 
the pixel values to compensate for this difference and produce a 
more accurate representation on the screen. By default, the correction factor 
is 2, on the assumption that the display is not otherwise 
gamma corrected. The DXHWGAMMA variable allows you to override this default. 
In particular, if the display device is already gamma corrected, set 
the variable to 1. #!N #!N #!N  #!F-adobe-times-medium-i-normal--18*   Next Topic #!EF
