# PDF Layers

Creates a PDF with layered content.

## Instruction

Write a C# program that creates a PDF with layers. One layer should be visible and another should be invisible. The code should draw shapes on each layer, and a line should be drawn without any layer.

## Usings

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

## Code Snippet

```csharp
using (var writer = new PdfWriter("PdfWithLayers.pdf"))
using (var gr = writer.GetGraphics())
{
    writer.AddPage(500, 500);

    // Visible layer
    gr.Layer = new Layer("Visible layer");

    gr.FillRectangle(new SolidBrush(RgbColor.Green), 0, 0, 100, 100);
    gr.FillEllipse(new SolidBrush(RgbColor.Green), 100, 0, 100, 100);

    // Invisible layer
    gr.Layer = new Layer("Invisible layer") { IsVisible = false };

    gr.FillRectangle(new SolidBrush(RgbColor.Red), 0, 300, 100, 100);
    gr.FillEllipse(new SolidBrush(RgbColor.Red), 100, 300, 100, 100);

    // No layer
    gr.Layer = null;

    gr.DrawLine(new Pen(RgbColor.Blue, 4), gr.Width, 0, 0, gr.Height);

    writer.Close();
}
```

## Explanation

Below is a C# code sample that demonstrates how to create a PDF with multiple layers. One layer is visible, another is invisible, and a line is drawn without any layer applied:

This code generates a PDF with a visible green layer, an invisible red layer, and a blue line drawn without any layer, allowing you to work with layers in PDF documents.
