Attributes

Name Type g/s Description
brightness float Brightness (default = 1.) Values below 1. (to 0.) reduce brightness, while values above 1. increase it. 1. represents no change.
contrast float Contrast (default = 1.) Values below 1. (to 0.) decrease contrast, bringing the image closer to grey (which represents the average luminance of the image frame). Values above 1.0 increase contrast. 1.0 represents no change. Negative values affect a color inversion, but with similar results.
saturation float Saturation (default = 1.) Values below 1. (to 0.) decrease saturation, bringing the image closer to greyscale. Values above 1. increase saturation. 1. represents no change. Negative values affect a color inversion, but with similar results.
