   int intensity
)

Parameters

contrast

Value that refers to the histogram stretching amount. It represents the amount of contrast change. The contrast ranges from -1000 to +1000. This value is divided internally by 1000. A positive value increases the contrast whereas a negative value decreases the contrast.

brightness

Value that refers to colors intensities scale factor. It indicates the amount of brightness change. The brightness ranges from -1000 to 1000. This value is divided internally by 1000. A positive value increases (or lightens) the brightness of the image image. A negative value decreases (or darkens) the brightness of the image image.

intensity

Value that refers to colors intensities shifting amount. It indicates the amount of intensity change. The intensity ranges from -1000 to +1000. This value is divided internally by 1000. A positive value lightens the brightness pixels whereas a negative value darkens the brightness pixels.

Run the ContrastBrightnessIntensityCommand on an image.
