Little CMS 2.12 released

I am glad to the announce the release 2.12 of the LittleCMS open source color engine.

lcms2-2.12 will add stability. Most of the new development has been done in fast float plug-in, now we have a integrated build system (a command line option in configure script) and more kernels, RGB to anything, and Lab to anything. The path “Lab to RGB” in float is specially useful. This release also recovers PDF for documentation, but at a reduced size.

Little CMS intends to be a small-footprint color management engine, with special focus on accuracy and performance. It uses the International Color Consortium standard (ICC), which is the modern standard when regarding to color management. The ICC specification is widely used and is referred to in many International and other de-facto standards.
