Hi Even, You are right, Kakadu 8.x supports HTJ2K. I just had a try with the kdu_compress demo utility from KDU805 demo apps. The speed was good, actually amazing. As a test image I used a 12000x12000 RGB image. The kdu_compress command I took from this high qualite white-paper https://htj2k.com/wp-content/uploads/white-paper.pdf.
kdu_compress -i p4433h.ppm -o tmp3.jph -rate 2 -tolerance 0 Qstep=0.001 -quiet -no_weights As a reference I used gdal_translate -of gtiff -co compress=jpeg p4433h.tif comp.tif Results (total time disk-to-disk on Windows, SSD disk, laptop with Intel core i7) kdu_compress - JPH: 1.4 seconds (file size 36 MB, fixed size defined by option -rate 2) kdu_compress - JPH: 1.1 seconds (file size 90 MB, fixed size defined by option -rate 5) gdal_translate - TIFF: 13.1 seconds (file size 92 MB) The Kakadu demo applications that can be acquired on request from the Kakadu site are compiled without libtiff and therefore the input must be in ppm format. Those who have access to Kakadu source code can compile the applications with "KDU_INCLUDE_TIFF". -Jukka Rahkonen- Even Rouault-2 wrote > I'm not sure which support of HTJ2K the ECW and MrSID SDKs have.
