Grayscale

DjvuImage.Grayscale method

Grayscale transformation converts an image to a black-and-white representation, where each pixel’s intensity is represented by a single value ranging from black to white. This process removes color information, resulting in a monochromatic image. Grayscale images are commonly used in applications where color is unnecessary or where simplicity is preferred, such as document scanning, printing, and certain types of image analysis.

public override void Grayscale()

Examples

The following example transforms a colored DJVU image to its grayscale representation. Grayscale images are composed exclusively of shades of gray and carry only intensity information.

[C#]

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

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(dir + "sample.djvu"))
{
    Aspose.Imaging.FileFormats.Djvu.DjvuImage djvuImage = (Aspose.Imaging.FileFormats.Djvu.DjvuImage)image;

    djvuImage.Grayscale();
    djvuImage.Save(dir + "sample.Grayscale.png", new Aspose.Imaging.ImageOptions.PngOptions());
}
