Post by Xn User »

Hi Pierre)
I test convert from JPEG2000 LuraWave to FLIF SMT 12 Streams in XnConvert 1.85.1 32 bit , and recive very distructed FLIF files.
Special damagdable will be if recompress large photos. Why so ?

This is bug in FLIF encoder or in FLIF coder absolute

This will be , if make 12-20 files from JP2LWF on type 001.jp2 , 002.jp2 and etc. Next add all jp2lwf files to XnConvert , set SMT with 12 threads or more , and run compress from JP2 to FLIF and next run recompress from FLIF to FLIF , if this maked , will be error on stage FLIF to FLIF and images will be corrupt. At least everytime files not will be identical on size and will be different on size from pass to pass.
