Property Item Descriptions
Property Item Descriptions
The following list gives descriptions of the property items supported by Windows GDI+. The descriptions are brief and general so that they apply to a variety of image file formats. For a detailed description of how a property item is used by a particular file format, see the specification for that file format. For links to several file specifications and other documents that describe metadata in detail, see Image File Format Specifications.
The Exchangeable Image File (EXIF) format is a Japan Electronic Industry Development Association (JEIDA) standard, revised June 1998 as version 2.1. Portions of the EXIF specification are used with permission of JEIDA.
