Put image annotations over the text (setting up ZIndex of image).

Since 21.5 you are now able to specify images placing order for file formats linked to Word. For this purpose a new ZIndex property has been added to ImageAnnotation class. You may now try in addition to other properties:

ImageAnnotation area = new ImageAnnotation
{
    Box = new Rectangle(100, 100, 100, 100),
    Opacity = 0.7,
    PageNumber = 0,
    ImagePath = "www.google.com.ua/images/branding/googlelogo/2x/googlelogo_color_92x30dp.png",
    Angle = 100,
    ZIndex = 3
};
