The Part II extension to the JPEG 2000 standard (ISO/IEC 15444-2) provides many additional definitions beyond a basic file format called JP2 and defined by Part I (ISO/IEC 15444-1). This extended file format is called JPX, and should use the file extension
.jpf, although.jpxis also used. Some JPX files can be written as JP2 files and a JP2 reader will skip "boxes" it doesn't understand.This PR allows us to import files with the aforementioned file extensions. The current JPEG 2000 file loader successfully loads sample .jpf files from https://github.com/openpreserve/format-corpus/tree/master/jp2k-formats and https://github.com/openpreserve/format-corpus/tree/master/jp2k-test.
