I'm looking to find a utility to convert files to lossless JPEG2000, and ImageMagic looked like a good solution.
Before I tried anything I came accross this info:
it would appear Jasper/ImageMagick is not using the reversible (integer) wavelet transform.
I have tried some tests myself, converting a TIFF from a Red Camera to JPEG2000, back to TIFF, and then comparing the results in Gimp, and the two images are not identical.
Any ideas? I would love to use ImageMagic, but this is a major stumbling block...
Edited to add that my tests were done with ImageMagick-6.4.1-3-Q16-windows-dll.exe
