As per subject, I wonder if we can some how "extract" the image in our RadDocument.

The background - I wanted user to be able to manipulate their photo via WPF apps but once it is uploaded to my website, I need those content to be translated into images so that I can save those images and refer to it via URL.

Hello SHSIOW,

As I understand from your question, you need to extract the images from a RadDocument instance, loaded in RadRichTextBox. Please correct me if I am wrong.

If this is the case, the following code extracts the images from the RadDocument and saves them to a specified location:   

List<ImageInline> images = radRichTextBox.Document.EnumerateChildrenOfType<ImageInline>().ToList();
 
string basePath = @"C:\SavedImages\{0}{1}{2}";
 
for (int i = 0; i < images.Count(); i++)
{
    ImageInline image = images[i];
    using (FileStream fs = File.Create(string.Format(basePath, i, ".", image.Extension)))
    {
        Stream imageStream = new MemoryStream(image.GetBytes());
        imageStream.Seek(0, SeekOrigin.Begin);
        imageStream.CopyTo(fs);
        imageStream.Close();
    }
}

Hope this helps.

Regards,
Boyko
