The general recommendation to record original scanned images used to be "use TIFF". But programmers need evolution of format for "evolution of software", and I need to evolve my system to change from TIFF to JP2.
I have a big image storage (terabytes) for legal and scientific scanned materials, they need original recording. I use some caching rules, but the system need to show (via web download) or to manipulate (ImageMagick and others) original data.
I've read an article about migrating image storages from TIFF-lossless to JPEG-2000-lossless and the conclusion is to stay with TIFF. However the article is from 2009 and at the time they found support for the JPEG-2000 format by available software was very poor. The conversions to JPEG-2000 were lossy in the software they tested, and the available software for consuming images did not support the format well.
Is now the time to change from TIFF to JP2, or not? Is the software support still as flawed as it was in 2009?
