RasterImage.AdjustGamma

AdjustGamma(float, float, float)

Gamma-correction of an image.

public virtual void AdjustGamma(float gammaRed, float gammaGreen, float gammaBlue)

Parameter	Type	Description
gammaRed	Single	Gamma for red channel coefficient
gammaGreen	Single	Gamma for green channel coefficient
gammaBlue	Single	Gamma for blue channel coefficient

Examples

The following example performs gamma-correction of an image applying different coefficients for color components.

[C#]

string dir = "c:\\temp\\";

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.png"))
{
    Aspose.Imaging.RasterImage rasterImage = (Aspose.Imaging.RasterImage)image;

    // Set individual gamma coefficients for red, green and blue channels.
    rasterImage.AdjustGamma(1.5f, 2.5f, 3.5f);
    rasterImage.Save(dir + "sample.AdjustGamma.png");
}
