![]() The escape sequence for UTF-8 character coding is "ESC % G", but this is displayed as "UTF8" for convenience. The IPTC Photo Metadata standard is the most widely used standard because of its universal acceptance among photographers, distributors, news organizations, archivists, and developers. (values are entered in the form "ESC X Y". For a complete description of the values available for a given attribute, please consult the IPTC IMM Specification.ġ = IPTC-NAA Digital Newsphoto Parameter Recordģ = Tagged Image File Format (Adobe/Aldus Image data)Ĩ = IPTC Unstructured Character Oriented File Format (UCOFF)ĩ = United Press International ANPA 1312 variantġ0 = United Press International Down-Load Messageġ3 = Bit Mapped Graphics File (Microsoft)ġ4 = Digital Audio File (Microsoft & Creative Labs)ġ5 = Audio plus Moving Video (Microsoft)ġ6 = PC DOS/Windows Executable Files ġ7 = Compressed Binary File (PKWare Inc)ġ8 = Audio Interchange File Format AIFF (Apple Computer Inc)Ģ1 = Hypertext Markup Language (The Internet Society)Ģ2 = MPEG 2 Audio Layer 2 (Musicom), ISO/IECĢ7 = Tidningarnas Telegrambyra NITF version (TTNITF DTD)Ģ8 = Ritzaus Bureau NITF version (RBNITF DTD) The tables below describe what tags are available on a Record basis. For example, you may be able to feed perspective depth to ROS package such as depthimageproc to generate a point cloud. Depending on your use case, planner depth or perspective depth may be the ground truth image that you want. Unlike EXIF however, IPTC does allow for repeat attributes, so attribute 2:25 (which is the keywords tag) may appear multiple times if more than one keyword is defined. For ImageType DepthPerspective, you get depth from camera using a projection ray that hits that pixel. IPTC defines nine Record values, however only 6 are used by images:Īs with EXIF the combination of a Record and Tag defines an individual attribute. Within a record a series of tags is used to specify individual attributes. IPTC has the concept of a broad category of attributes, known as a Record. IPTC metadata is stored in a similar format to that used for EXIF. In general, the IPTC information is as relevant to any image derivative as to the master image. ![]() IPTC focuses on information about the subject of the image rather than its physical attributes, thus it contains information such as keywords, copyright statements, location details and subject of the image. ![]() The standard became known as the IPTC standard. The International Press Telecommunications Council released a metadata standard in 1990 that was to allow contextual information to be embedded within press photographs.
