[gdal-dev] Long Term Prognosis for JPEG 2000

[Kurt Schwehr]

Jp2k is likely to continue with heavy use for a long time to come.  There
are lots of hardware encoders in our solar system and the existing base of
data in that format is massive.  And with the improvements in Openjpeg,
it's support seems viable.  It's not the first choice for most, but that's
okay.
