Hello, What version of libnetcdf are you working with? JPEG-LS is not a natively-supported compression format for netCDF variables, but it is possible that you are accessing netCDF4 data using plugin support via the underlying HDF5 library. Is this what you are doing? Or is the data compressed with JPEG-LS outside of netCDF/stored in a non-netCDF file? -Ward > Hi, I work in C# and I use netcdf.dll functions for read netcdf meteorology > file but I have problem any data are compress with JPEG-LS algoritm and I > can not read these data , Is possible make function for read these compress > data or use any filter for decompress ,If I can read data I can use > decompress from https://github.com/team-charls/charls , but I must get any > data from variable I so far get empty array from variable , I very like if > team fro UNIDATA make add function to netcdf.h and netcdf.dll,Thanks > Hi, I work in C# and I use netcdf.dll functions for read netcdf meteorology > file but I have problem any data are compress with JPEG-LS algoritm and I > can not read these data , Is possible make function for read these compress > data or use any filter for decompress ,If I can read data I can use > decompress from https://github.com/team-charls/charls , but I must get any > data from variable I so far get empty array from variable , I very like if > team fro UNIDATA make add function to netcdf.h and netcdf.dll,Thanks > Hi, I work in C# and I use netcdf.dll functions for read netcdf meteorology > file but I have problem any data are compress with JPEG-LS algoritm and I > can not read these data , Is possible make function for read these compress > data or use any filter for decompress ,If I can read data I can use > decompress from https://github.com/team-charls/charls , but I must get any > data from variable I so far get empty array from variable , I very like if > team fro UNIDATA make add function to netcdf.h and netcdf.dll,Thanks > Hi, I work in C# and I use netcdf.dll functions for read netcdf meteorology > file but I have problem any data are compress with JPEG-LS algoritm and I > can not read these data , Is possible make function for read these compress > data or use any filter for decompress ,If I can read data I can use > decompress from https://github.com/team-charls/charls , but I must get any > data from variable I so far get empty array from variable , I very like if > team fro UNIDATA make add function to netcdf.h and netcdf.dll,Thanks Ticket Details =================== Ticket ID: EIE-261011 Department: Support netCDF Priority: Normal Status: Closed =================== NOTE: All email exchanges with Unidata User Support are recorded in the Unidata inquiry tracking system and then made publicly available through the web.
