# Draw Spot On CMYK

Draws a text and an image on the spot channel, using the existing CMYK image as a background.

## Instruction

Write a C# program that draws text and an image on the spot channel using a CMYK background in a PDF.

## Usings

```csharp
using Aurigma.GraphicsMill.Codecs;
using Aurigma.GraphicsMill.Drawing;
```

## Code Snippet

```csharp
using (var bgImageReader = ImageReader.Create("Copenhagen_CMYK.jpg"))
using (var pdfWriter = new PdfWriter("SpotWithProcessColors.pdf"))
{
    Pipeline.Run(bgImageReader + pdfWriter);

    using (var gr = pdfWriter.GetGraphics())
    using (var spotImage = new Bitmap("Sheep.gif"))
    {
        var ink = new Ink("PANTONE Red 032 C", new RgbColor(243, 40, 55));
        var spotColor = new SpotColor(ink, 255);
        var text = new PlainText("Spot color text", gr.CreateFont("Arial", 150))
        {
            Position = new System.Drawing.PointF(gr.Width / 2, gr.Height / 2),
            Alignment = TextAlignment.Center,
            Brush = new SolidBrush(spotColor),
        };

        gr.DrawText(text);

        // After these operations, the loaded image reflects a spot color
        spotImage.ColorManagement.Ink = ink;
        spotImage.ColorManagement.Convert(PixelFormat.Format16bppAspot);

        spotImage.Transforms.Resize(400, 400, Aurigma.GraphicsMill.Transforms.ResizeInterpolationMode.Linear, Aurigma.GraphicsMill.Transforms.ResizeMode.Fit);

        gr.DrawImage(spotImage, gr.Width - spotImage.Width, gr.Height - (spotImage.Height / 3));
    }

    pdfWriter.Close();
}
```

## Explanation

Below is a C# code sample that demonstrates how to draw text and an image on the spot channel in a PDF document,
using an existing CMYK image as the background. It uses `PdfWriter` and `ImageReader` to work with the background and spot colors:

This code creates a PDF where text and an image are drawn with a PANTONE spot color on top of a CMYK background image.
