Content-Type: text/plain; charset=UTF-8; format=flowed Reply-To: djgpp AT delorie DOT com This is a port of library lcms2 2.7 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 2.05. 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 too: ftp://ftp.delorie.com/pub/djgpp/current/v2tk/zlib128br2.zip ftp://ftp.delorie.com/pub/djgpp/current/v2tk/tiff406b.zip ftp://ftp.delorie.com/pub/djgpp/current/v2tk/png1623b.zip ftp://ftp.delorie.com/pub/djgpp/current/v2tk/jpeg9bb.zip ftp://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 "_build" directory located under the top source directory. If for some reason you need to reconfigure the sources delete the complete contain of the "_build" directory and run the following command: ..\djgpp\config.bat ./.. This is a verbatim extract of the ChangeLog file: ------------------------------------------------------------------------------- ----------------------- 2.7 Maintenance release ----------------------- Fixed a possible segmentation fault in a non-happy path Fixed a macro clash on SNONE. Added a safety check on named color lists Added a function to retrieve the iohandler of a given profile object Remove unused vcproj files Some maintenance fixes utils/jpgicc/iccjpeg.c: Fix check if unsigned variable 'total_length'… … Add missing comma in CGATS parser Remove dead code. Move unused var suppresor before the `return` statements. Added a flag to clip negative values in unbounded transforms (only gray, rgb, cmyk) Added a global optimization that merges consecutive matrices in pipelines. Fixes loss of precision in some transforms New project for mac Added license for iccjpeg.c Added a project for VS2013 Fixed wrong handling of extra channels in some formatters. Added an option in transicc for working in bounded mode Added a version retrieval function ------------------------------------------------------------------------------- The port consists of the usual three packages produced using djdev205 that can be downloaded from ftp.delorie.com and mirrors as (time stamp 2016-07-22): library lcms2 2.7 binaries, headers, libs and man format documentation: ftp://ftp.delorie.com/pub/djgpp/current/v2tk/lcms27b.zip library lcms2 2.7 pdf format documentation: ftp://ftp.delorie.com/pub/djgpp/current/v2tk/lcms27d.zip library lcms2 2.7 source: ftp://ftp.delorie.com/pub/djgpp/current/v2tk/lcms27s.zip Send library lcms2 specific bug reports to .
