Name: Quick Color Management System
Short Name: qcms
URL: https://github.com/jrmuizel/qcms/tree/v4
Version: v4
Date: 2012-03-13
License: MIT
License File: src/COPYING
Security Critical: yes
Description:
Contains support for applying an ICC color profile to an image. The code is
originally based on tinycms, re-written by Mozilla for better security and
performance. This copy is a source-drop from Mozilla on March 13, 2012.
Local Modifications:
Some files only have license headers in the master branch.
- Added the same license headers to the versions brought down from the 'v4'
branch src URL qcms/tree/v4
The following changes have been made since qcms was imported:
- Add bgra output support.
- Use HAVE_POSIX_MEMALIGN instead of HAS_POSIX_MEMALIG

- Applied upstream patch:

enabled.
