SaveCmyk32Pixels

RasterImage.SaveCmyk32Pixels method

Saves the pixels.

public void SaveCmyk32Pixels(Rectangle rectangle, int[] pixels)
Parameter Type Description
rectangle Rectangle The rectangle to save pixels to.
pixels Int32[] The CMYK pixels presented as the 32-bit integer values.

Examples

The following example fills the central area of a raster image with black pixels using the Aspose.Imaging.RasterImage.SaveCmyk32Pixels method.

[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;

    // Get an integer representation of black in the CMYK color space.
    int blackCmyk = Aspose.Imaging.CmykColorHelper.ToCmyk(Color.Black);

    // The black square.
    int[] pixels = new int[(rasterImage.Width / 2) * (rasterImage.Height / 2)];
    for (int i = 0; i < pixels.Length; i++)
    {
        pixels[i] = blackCmyk;
    }

    // Draw the black square at the center of the image.
    Aspose.Imaging.Rectangle area = new Aspose.Imaging.Rectangle(rasterImage.Width / 4, rasterImage.Height / 4, rasterImage.Width / 2, rasterImage.Height / 2);
    rasterImage.SaveCmyk32Pixels(area, pixels);

    rasterImage.Save(dir + "sample.SaveCmyk32Pixels.png");
}
