# Read Clipping Path Flatness

Read a TIFF image that contains an Adobe resource block for clipping paths, retrieve and display the clipping path name and flatness.

## Instruction

Read a TIFF image that contains an Adobe resource block for clipping paths, retrieve and display the clipping path name and flatness value.

## Usings

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

## Code Snippet

```csharp
using (var reader = new TiffReader("TIFFWithClippingPath.tif"))
{
    const int clippingPathKey = 0x0bb7;

    if (reader.AdobeResources.Contains(clippingPathKey))
    {
        var arb = (AdobeResourceBlock)reader.AdobeResources[clippingPathKey];

        byte nameSize = arb.Data[0];

        Console.WriteLine($"Clipping path name: {System.Text.Encoding.UTF8.GetString(arb.Data.Skip(1).Take(nameSize).ToArray())}");

        // Flatness is a fixed point value in format 8p16: one byte for integer and 2 bytes for fractional.
        float flatness = (float)arb.Data[nameSize + 2] + ((float)(arb.Data[nameSize + 3] << 8 | arb.Data[nameSize + 4]) / ushort.MaxValue);

        Console.WriteLine($"Flatness: {flatness}");
    }
}
```

## Explanation

The code:

- Reads the "TIFFWithClippingPath.tif" image.
- Extracts the clipping path from the Adobe resources using the specified key (0x0bb7).
- Displays the clipping path name and the flatness value, which is a fixed point number extracted from the Adobe resource block.
