Obtaining pictures within other objects

[robertop19.rp]

I'm having trouble obtaining pictures from a Word document. I use the following method to get the pictures:

foreach (Spire.Doc.Section section in document.Sections)
{
foreach (Spire.Doc.Documents.Paragraph paragraph in section.Paragraphs)
{
foreach (DocumentObject docObject in paragraph.ChildObjects)
{
if (docObject.DocumentObjectType == DocumentObjectType.Picture)
{
//get docObject as DocPicture
DocPicture picture = docObject as DocPicture;

//Name Image
String imageName = String.Format(mainPath + @"Pictures\" + String.Format("img_{0}.png", pictureCount));

//Save Image
picture.Image.Save(imageName, System.Drawing.Imaging.ImageFormat.Png);

pictureCount++;
}
}
}
}

This works occasionally because sometimes the pictures seem to be within other pictures or drawings. I've included a sample of these troublesome pictures along with this post. Please tell me how I could save these pictures because the method above won't catch them at all.

I'm sorry. Turns out I provided the wrong sample document. I posted a question on this forum before with a question about nullFontName but that's not the case with with this forum question. This reply contains the correct document; the one's with the unreachable pictures.

Hello,

Thanks for your information. After investigation, we found that two objects in your document are not pictures, they are group. If you want to extract the picture, please ungroup and then extract the picture.

Can I ungroup using Spire.Doc C#?
