Remarks

The value of the Type property on a Property object when it comes from a Properties collection on an ImageFile object can return one of the members of the WiaImagePropertyType enumeration. This provides more information about the type of value contained in the Value property. A member of the WiaImagePropertyType enumeration can also be used as the value of the Type property in an Exchangeable Image File (EXIF) filter to specify the type of property to add to an image.

For example code, see Display all ImageFile Properties and Exif Filter: Write a New Title Tag to an Image.
