# Enum Container Elements

Enumerates the elements of a graphics container.

## Instruction

Enumerate and print the content of a graphics container extracted from a PDF file.

## Usings

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

## Code Snippet

```csharp
public static class Extensions
{
    public static void PrintContent(this GraphicsContainer container)
    {
        foreach (var shapeItem in container.Items.OfType<ShapeItem>())
        {
            Console.WriteLine("Shape:");

            if (shapeItem.Brush != null)
            {
                Console.WriteLine($"  {shapeItem.Brush.ToString()}");
            }

            if (shapeItem.Pen != null)
            {
                Console.WriteLine($"  {shapeItem.Pen.ToString()}");
            }
        }

        foreach (var imageItem in container.Items.OfType<ImageItem>())
        {
            Console.WriteLine($"Image: {imageItem.Image.Width}x{imageItem.Image.Height}");
        }

        foreach (var textItem in container.Items.OfType<TextItem>())
        {
            Console.WriteLine($"Text: {textItem.Text.String}");
        }

        foreach (var containerItem in container.Items.OfType<ContainerItem>())
        {
            containerItem.GraphicsContainer.PrintContent();
        }
    }
}

internal class EnumGraphicsContainerContent
{
    public static void Run()
    {
        using (var reader = new PdfReader("GraphicsContainer.pdf"))
        using (var gc = reader.Frames[0].GetContent())
        {
            gc.PrintContent();
        }
    }
}
```

## Explanation

The following code:

- Defines an extension method `PrintContent` for `GraphicsContainer`.
- Iterates over the container’s items, printing info about shapes, images, and text.
- Recursively enumerates nested `ContainerItem` instances.
- The `Run()` method reads a PDF file and prints the contents of the first frame’s graphics container to the console.
