Deleting images from pdf does not work as expected

Aspose.PDF Product Family
1

I have a pdf and I want to delete images from the document, but the results are not as expected.

Issue 1: There are pictures in the document, but I can’t get them.
Issue 2: I wanted to clear the picture, but all content has been cleared.

void Main()
{
	InitCoreComponent();
	var pdf = new Aspose.Pdf.Document(@"C:\Users\54390\Downloads\8620d444c93e4301be7bc36ca19b622e.pdf");
	
	RemoveAllImage(pdf);
	
	pdf.Save(@"C:\Users\54390\Downloads\output.pdf");
}

public static void RemoveAllImage(Aspose.Pdf.Document doc)
{
	doc.Pages.ToList().ForEach(page =>
	{
		var imgs = page.Resources?.Images;
		if (null == imgs)
		{
			return;
		}
		//Issue 1: Can not get any image, The output is 0.
		Console.WriteLine(imgs.Count);
		//Issue 2: All content has been cleared.
		imgs.Clear();
	});
}
