Image.ImageData.GrayScale is always returning false when we add a Grayscale image to word document( all formats (.docx, .doc, .rtf) .Below is the code I used to run for checking Grayscale .Attached the grayscale images along with the post.
I have used the following code :
Document doc = new Document(“document1.docx”);
foreach (Shape image in doc.GetChildNodes(NodeType.Shape, true))
bool isGrayScale = image.ImageData.GrayScale;
