RasterImageBinarizeFixed Method
Binarization of an image with predefined threshold

Namespace: Aspose.Imaging
Assembly: Aspose.Imaging (in Aspose.Imaging.dll) Version: 20.03
Syntax
public virtual void BinarizeFixed(
	byte threshold
)

Parameters

threshold
Type: SystemByte
Threshold value. If corresponding gray value of a pixel is greater than threshold, a value of 255 will be assigned to it, 0 otherwise.
Examples
The following example binarizes a raster image with the predefined threshold. Binarized images contain only 2 colors - black and white.
[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;

    // Binarize the image with a threshold value of 127.
    // If a corresponding gray value of a pixel is greater than 127, a value of 255 will be assigned to it, 0 otherwise.
    rasterImage.BinarizeFixed(127);
    rasterImage.Save(dir + "sample.BinarizeFixed.png");
}
