Public API and Backward Incompatible Changes
New public class ImageMetadataSignature was added to support Metadata signatures for Image Documents. Image Metadata signatures are based on Exchangeable image file format (Exif) specification. The Exif data references are specified standard and custom image properties of various type of data.
FormField Signature properties:
Id ushort Specifies unique exif tag identifier. See documentation of TIFF Tag Reference Size int Specifies size of Metadata value. Property is read only and set automatically once value will be changed Description string Specifies description of Metadata signature when standard identifier metadata signature is being used
Class specifies unique identifier Id to follow Exif specification, Name property contains Id in hex format, read-only property Description contains extended description for standard image exif data, read-only property Size keeps the size of metadata signatures.
New class ImagesSearchMetadataOptions represents options for search for Image metadata signatures.
Following example demonstrates how to search for Image Metadata Signatures:
