8 years ago Hi Brian,
Actually this is something I briefly considered when I started the development of jpylyzer, but mapping JPEG 2000 properies to corresponding MIX elements isn't that straightforward. Some examples, from the top of my head (there are more):
- The JP2 spec allows the use of multiple Colour Specification boxes, which may contain conflicting information. So how should this be handled in MIX?
- JPEG 2000 has 2 different sets of fields for storing resolution info (Capture and Display resolution), which can have different values. Also here any mapping to MIX x/y samplingFrequency will be pretty arbitrary.
Because of this I'm not in favor of handling MIX output within jpylyzer itself. For users who need output in MIX format, I think this could be done most easily as post-processing using XSLT transformations. I don't have any experience with that myself, but if anyone is interested in writing some stylesheets, I'd be happy to include them in the jpylyzer distribution.
Not sure if this the best forum. I couldn't find a listserv or wiki.
It would a marvelous thing if the technical metadata could be rendered as valid MIX 2.0, either as a supplement nested within the output or as an alternative. Has there been any discussion of this?
