Can anyone with knowledge of the JP2OpenJPEG driver confirm or deny the following observation?
I've been generating jpeg2000's in both GDAL 1.11.2 and GDAL 2.1. With all settings the same, I've noticed the visual quality of the images generated in GDAL 2.1 are noticeably "better." (a subjective term, yes) To my eyes, in 1.11.2, -co "QUALITY=20" yields results visually comparable to roughly -co "QUALITY=12" in GDAL 2.1. Win32 platform, binaries from gisinternals.com. Are there significant improvements in the 2.1 driver that would explain my observation? ---------------------------------------------- Jim Lacy Wisconsin State Cartographer's Office University of Wisconsin-Madison (608) 262-6850 www.sco.wisc.edu<http://www.sco.wisc.edu/> My calendar: http://go.wisc.edu/xziys4
