# Modify Clipping Path Explicitly

Modifies clipping path explicitly.

## Instruction

Crop the image while modifying its clipping path explicitly and save the result as a JPEG file.

## Usings

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

## Code Snippet

```csharp
using (var reader = new JpegReader("Apple.jpg"))
using (var bitmap = reader.Frames[0].GetBitmap())
{
    var crop = new Crop(20, 20, bitmap.Width - 40, bitmap.Height - 40);

    var cropped = crop.Apply(bitmap);

    var clippingPath = reader.ClippingPaths[0];

    clippingPath.ApplyTransform(crop.GetPathTransformMatrix(bitmap.Width, bitmap.Height).ToGdiPlusMatrix());

    var adobeResources = new AdobeResourceDictionary();
    adobeResources.Add(FirstPathId, new AdobeResourceBlock("Apple", clippingPath.Data));

    var jpegSettings = new JpegSettings();
    jpegSettings.AdobeResources = adobeResources;

    cropped.Save("ModifyClippingPathExplicitly.jpg", jpegSettings);
}
```

## Explanation

The code:

- Reads the "Apple.jpg" image and extracts its first frame.
- Crops the image using specified coordinates (20, 20) to (bitmap.Width - 40, bitmap.Height - 40).
- Modifies the clipping path associated with the image by applying the crop transformation.
- Creates an Adobe resource dictionary and adds the modified clipping path to it.
- Saves the cropped image with the updated clipping path to "ModifyClippingPathExplicitly.jpg" with the Adobe resources (clipping path) included.
