  • ANNOUNCE: DJGPP port of library lcms2 2.14 uploaded.

    From [via djgpp-announce@delorie.com]" <@21:1/5 to All on Fri Dec 30 00:47:11 2022
    This is a port of library lcms2 2.14 to MSDOS/DJGPP.


    The little cms library intends to be a small-footprint, speed optimized color
    management engine in open source form written in C.
    Here some features taken from the information provided by the lcms home page
    http://www.littlecms.com:
    Basic features:
    Widely portable.
    Easy to use.
    Small, tight code.
    Fast, optimized for speed.
    Handles a wide range pixel formats.
    Implements ICC spec 4.2
    Profile to profile and multiprofile transforms.
    Supports all kind of profiles, including named color
    PostScript CSA and CRD generation

    Advanced features:
    Full multicolor support, including proof direction in more than 4 inks.
    Black preservation on CMYK->CMYK transforms.
    Gamut checking.
    Softproofing.
    Precalculated device link transforms with prelinearization step.
    Virtual Gray, RGB profiles.
    CIECAM02 appearance model.
    Can write profiles as well.
    Built-In profiles.
    Specialized abstract virtual profiles.
    Ink limiting.

    Please note that this is a library only for programmers. If you do not
    understand all these, you do not need the port. lcms is a CMM engine;
    it implements fast transforms between ICC (international color consortium)
    profiles. lcms is NOT a file format or display library. lcms knows nothing
    about how to display bitmaps (JPEG, TIFF, GIF or whatever).



    DJGPP specific changes.
    =======================


    The port has been adjusted and fixed to be compiled with DJGPP 2.0X (CVS
    repository code). Please note that the sources may not be compilable if
    LFN support is not available.

    All DJGPP specific stuff is stored in the "djgpp" directory.

    To configure and compile the package you will have to install the following
    packages:
    http://ftp.delorie.com/pub/djgpp/current/v2tk/zlb1212b.zip
    http://ftp.delorie.com/pub/djgpp/current/v2tk/tiff450b.zip
    http://ftp.delorie.com/pub/djgpp/current/v2tk/png1639b.zip
    http://ftp.delorie.com/pub/djgpp/current/v2tk/jpeg9eb.zip
    http://ftp.delorie.com/pub/djgpp/current/v2tk/jbig21br2.zip
    Of course, you can always download newer versions of these ports if available.

    The source package has been configured to be build in the "0build" directory
    located under the top source directory. If for some reason you need to
    reconfigure the sources delete the complete contain of the "0build" directory
    and run the following command:
    ..\djgpp\config.bat ./..
