The brightness
must be in range (-100, 100)
.

ColorBalance creates a filter that changes the color balance of an image. The percentage parameters for each color channel (red, green, blue) must be in range (-100, 500)
.
1
Colorize creates a filter that produces a colorized version of an image. The hue parameter is the angle on the color wheel, typically in range (0, 360)
. The saturation parameter must be in range (0, 100)
. The percentage parameter specifies the strength of the effect, it must be in range (0, 100)
.
1
The contrast
must be in range (-100, 100)
.
1
Gamma creates a filter that performs a gamma correction on an image. The gamma parameter must be positive. Gamma = 1 gives the original image. Gamma less than 1 darkens the image and gamma greater than 1 lightens it.
1
Applies a gaussian blur to an image.
1
Grayscale creates a filter that produces a grayscale version of an image.
1
Hue creates a filter that rotates the hue of an image. The hue angle shift is typically in range -180
to 180
.
1
Invert creates a filter that negates the colors of an image.
1
Apply a opacity filter on an image.
1
Pixelate creates a filter that applies a pixelation effect to an image.
1
Saturation creates a filter that changes the saturation of an image.
1
Sepia creates a filter that produces a sepia-toned version of an image.
1
Sigmoid creates a filter that changes the contrast of an image using a sigmoidal function and returns the adjusted image. It’s a non-linear contrast change useful for photo adjustments as it preserves highlight and shadow detail.
1
UnsharpMask creates a filter that sharpens an image. The sigma parameter is used in a gaussian function and affects the radius of effect. Sigma must be positive. Sharpen radius roughly equals 3 * sigma. The amount parameter controls how much darker and how much lighter the edge borders become. Typically between 0.5
and 1.5
. The threshold parameter controls the minimum brightness change that will be sharpened. Typically between 0
and 0.05
.
