[Openev-discuss] creation of Wavelet compressed images via GDAL/OpenEV

[Frederic C. <fcl...@cs...>]

dear OpenEV / FWTools developpers,
I noticed FWTools OpenEV 0.96 can create ECW files & Kakadu JPEG2000,
whereas library GDAL cannot according to the documentation:
i'm interested in file creation, not in already existing file update.

for instance, 
-here's what I got from a Jasper & ECW enabled GDAL 1.2.6.0 (Linux):
gdalwarp --formats
  JPEG2000 (rw): JPEG-2000 part 1 (ISO/IEC 15444-1)
  ECW (rw): ERMapper Compressed Wavelets
  JP2ECW (rw+): ERMapper JPEG2000

-here what i got from FWTools 0.96 gdalwarp (Windows):
 JP2KAK (rw): JPEG-2000 (based on Kakadu)
 ECW (rw): ERMapper Compressed Wavelets
 JP2ECW (rw+): ERMapper JPEG2000

can you explain how FWtools manage to create those file when exporting
data?

unfortunately, there seems to be a problem with Jasper my JPEG2000, so
far I cannot create any wavelet compressed image.
thanks for your guidance,
Frederic Claudel
