The JPEG2000-hul module recognizes and validates the JPEG 2000 (ISO/IEC 15444) format, a digital representation format for lossy or losslessly-compressed bi-tonal, grayscale, palette color, and continuous color still image data.
The module is invoked by the:
command line option.jhove ... -m JPEG2000-hul ...
The JPEG2000-hul module recognizes and validates the following public profiles:
The following criteria must be met by a JPEG 2000 object for JHOVE to consider it well-formed:
The following criteria must be met by a JPEG 2000 file for JHOVE to consider it valid:
The MIME type for the JP2 profile is reported as: image/jp2; for the JPX profile: image/jpx.
In addition to the standard JHOVE representation information, the following JPEG 2000-specific properties are reported:
Image technical properties are reported in terms of the NISO Z39.87 data dictionary.
JP2 is the file format defined by ISO/IEC 15444-1:2000/ITU-T Rec. T.800 (2002) [JP2, ITU-T T.800]. The JP2 profile provides a baseline format for the exchange of still image data using a limited range of colorspaces.
Profile requirements include:
JPX is the file format defined by ISO/IEC 15444-2:2004 [JPX]. The JPX profile provides extensions to JP2 that allow additional colorspaces, the specification of opacity, standardized metadata, multiple image data streams, and more non-contiguous internal organization of the image data.
Profile requirements include:
