Date: Wed, 3 Dec 1997 19:26:18 -0800 (PST) From: Andy Mutz To: iana&ISI.EDU, andy_mutz&hp.com Subject: Request for MIME media type Application/Vendor Tree - vnd.netfpx Name : Andy Mutz E-mail : andy_mutz&hp.com MIME media type name : Application MIME subtype name : Vendor Tree - vnd.netfpx Required parameters : none Optional parameters : none Encoding considerations : binary data is transmitted; base64 generally preferred Security considerations : Data communicated using this method is a collection of closely defined 64x64 pixel image tiles and/or metadata. Tiles are intended for decoding and display while metadata contains either information necessary for decoding and display or other information such as author, title, etc. None of the data defined are intended for explicit execution on a machine. The ability to define optional named metadata is described in the specification and it is not possible to predict the future behavior of optional named metadata. It is not the intention of the Digital Imaging Group to support executable data segments within this application. Some of the metadata is intended to cause image processing such as sharpening and rotation to occur and numerical errors such as divide-by-zero could be caused by inappropriate values of these parameters. Textual metadata can be displayed on a terminal, and is usually communicated as UNICODE. Some operating systems or terminals might allow the display of textual data with embedded control characters to perform operations such as re-mapping of keys, creation of files, etc. For this reason, text chunks should be filtered for control characters before direct display. Some of the data methods supported by this application are binary-stream oriented and could provide access to unanticipated data within a file, such as old edits of a document. For this reason, these methods should be restricted to appropriate files. These data methods are described in detail in the specification. Interoperability considerations : Intended for use by any application implementing the specification. Published specification : The IIP 1.0 specification is available from http://image.hp.com and from http://www.kodak.com. The authoritative source will be hosted beginning in 1998 at http://www.digitalimaging.org. The FlashPix specification, which is referred to by the IIP spec, is available from the same sources. The Digital Imaging Group maintains control over these specifications. Applications which use this media : Hewlett-Packard Company Imaging for Internet, Live Picture Realspace, Additional information : 1. Magic number(s) : n/a 2. File extension(s) : often used with .fpx files. 3. Macintosh file type code : n/a IIP version is indicated by a particular named metadata object called "iip". Person to contact for further information : 1. Name : Andy Mutz 2. E-mail : andy_mutz&hp.com Intended usage : Common This data type is request-driven and intended for dynamic retrieval of multiresolution image information. It may be generated from many static file formats. It is best suited to environments where several requests and responses may be quickly performed. Generally a single transmission does not yield a displayable image.
