Enumeration that represents recognized EXIF tags found in TIFF IFDs.

Items can be cast to u32 in order to get the namespace (most significant word) and tag code (least significant word). The tag code matches the Exif, or the Makernote standard, depending on the namespace that the tag belongs to.

On the other hand, the namespace code is arbitrary, it only matches the Namespace enumeration. The namespace is 0 for standard Exif tags. The non-standard namespaces exist to accomodate future parsing of the MarkerNote tag, that contains embedded manufacturer-specific tags.

Variants

UnknownToMe

Tag not recognized are partially parsed. The client may still try to interpret the tag by reading into the IfdFormat structure.
