AdjustGamma

RasterCachedImage.AdjustGamma method (1 of 2)

Gamma-correction of an image.

public override void AdjustGamma(float gammaRed, float gammaGreen, float gammaBlue)
ParameterTypeDescription
gammaRedSingleGamma for red channel coefficient
gammaGreenSingleGamma for green channel coefficient
gammaBlueSingleGamma for blue channel coefficient

Examples

The following example performs gamma-correction of a raster cached 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.RasterCachedImage rasterImage = (Aspose.Imaging.RasterCachedImage)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");
}
