Class CmykColorHelper
Namespace: Aspose.Imaging
Assembly: Aspose.Imaging.dll (25.2.0)
Helper methods to work with CMYK color presented as a signed 32-bit integer value. Provides the similar API as the Aspose.Imaging.CmykColor struct. It’s more lightweight because CMYK color is presented just as Int32 rather than structure with internal fields. Please prefer to use static methods of this class when possible instead of the deprecated Aspose.Imaging.CmykColor struct.

black int
The black component. Valid values are 0 through 255.
Returns
The CMYK color presented as a 32-bit integer value.
Examples
The following example shows how to convert CMYK colors to their RGB counterparts in a fast manner following straightforward formulas without using ICC profiles.```csharp [C#]
int[] cmykColors = new int[]
{
Aspose.Imaging.CmykColorHelper.FromComponents(255, 0, 0, 0), // Cyan
Aspose.Imaging.CmykColorHelper.FromComponents(0, 255, 0, 0), // Magenta
Aspose.Imaging.CmykColorHelper.FromComponents(0, 0, 255, 0), // Yellow
Aspose.Imaging.CmykColorHelper.FromComponents(0, 0, 0, 255), // Black
};
System.Console.WriteLine("Convert CMYK to RGB without using ICC profiles.");
foreach (int cmykColor in cmykColors)
{
Aspose.Imaging.Color rgbColor = Aspose.Imaging.CmykColorHelper.ToArgb(cmykColor);

//The output looks like this:
//Convert CMYK to RGB without using ICC profiles.
//CMYK(255,0,0,0) => RGB(0,255,255)
//CMYK(0,255,0,0) => RGB(255,0,255)

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