Adjustment - Gamma Curve
Adjustment in the Tool menu becomes valid only if <Halftone> or <Grayscale> have
been selected in <Image Type> on the main window.
Display a dialog box for adjusting the gamma (color strength characteristics) of an image. (valid only
when halftone or grayscale is selected)
Adjust the gamma curve by dragging the slide bar or entering a value.
Moving the slide bar in the + direction reduces the difference between the highlight (light portion) and
halftone. Moving the slide bar in the - direction reduces the difference between the shadow (dark portion)
and halftone. In either case, the halftone becomes less prominent.
Click the button to apply the changes.
