Description

Hi @dlemstra ,
I'm working with the SetClippingPath function. It's seem not work at this time.
Could you please help me to take a look at it?

Thanks

Steps to Reproduce

The step to reproduce is very simple:

1. Get my tif file and svg file from images.zip
2. Use this code to write the clipping path from svg to the tiff, then write it

using (var image = new MagickImage('input.tif'))
{
    image.SetClippingPath( File.ReadAllText(@"input.svg"), "Path 2");
    image.Write("output.tif", MagickFormat.Tiff);
}

3. Open this file again, you can see the it's missing the new clipping path

using (var image = new MagickImage("output.tif"))
{
    var clippingPath = image.GetClippingPath("Path 2");
}

System Configuration

• Magick.NET version: Magick.NET-Q8-x64 v7.14.1.0
• Environment: Windows 10

The clip path of a tiff image is stored in an EightBimProfile and when you set it on the image it just sets an attribute on the image so other code can use it. If you want to have it stored in the image you will need to create an EightBimProfile and store the profile there. If you look at the code of the class you can see how it is read and reverse engineer how to store it in the profile.
