X-Authentication-Warning: delorie.com: mail set sender to djgpp-bounces using -f Message-Id: <202102251712.11PHCSck015036@delorie.com> Date: Thu, 25 Feb 2021 17:53:03 +0100 From: "Juan Manuel Guerrero (juan DOT guerrero AT gmx DOT de) [via djgpp-announce AT delorie DOT com]" To: djgpp-announce AT delorie DOT com Subject: ANNOUNCE: DJGPP port of library lcms2 2.12 uploaded. Content-Type: text/plain; charset=ISO-8859-15; format=flowed Reply-To: djgpp AT delorie DOT com This is a port of library lcms2 2.12 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/v2apps/xz-525a.zip ftp://ftp.delorie.com/pub/djgpp/current/v2tk/zlb1211b.zip ftp://ftp.delorie.com/pub/djgpp/current/v2tk/tiff420b.zip ftp://ftp.delorie.com/pub/djgpp/current/v2tk/png1637b.zip ftp://ftp.delorie.com/pub/djgpp/current/v2tk/jpeg9db.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 ./.. Here is an extract of the ChangeLog file showing the user visible changes from the last port (library lcms2 2.9) to this one: ------------------------------------------------------------------------------- ----------------------- 2.12 Maintenance release ----------------------- Added new build-in sigmoidal tone curve Added XCode 12 project Added support for multichannel input up to 15 channels Fix LUT8 write matrix Fix version mess on 10/11 Fix tools & samples xgetopt Fix warnings on different function pointers Fix matlab MEX compilation plugin: cleanup and better SSE detection plugin: add lab to any on float plugin: it can now be compiled as C++ recover PDF documentation, but try to keep it under a resonable size. Prevent a rare but possible out-of-bounds read in postscript generator Remove unused variables ----------------------- 2.11 Maintenance release ----------------------- Fixed __cpuid() on fast float plugin to allow gnu gcc Fixed copy alpha bounds check Fixed data race condition on contexts pool Fixed LUT16 write matrix on multichannel V2 profiles ----------------------- 2.10 Featured release ----------------------- Added a compilation toggle to remove "register" keyword in API. Previously commercial, fast_float plug-in is now released as open source under GPL3 license. MD5 functions are now accesible through plug-in API. Added support for Visual Studio 2019 Bug fixing. ------------------------------------------------------------------------------- The port consists of the usual three packages that have been produced using djdev205 (CVS repository code) and can be downloaded from ftp.delorie.com and mirrors as (time stamp 2021-02-24): library lcms2 2.12 binaries, headers, libs and man format documentation: ftp://ftp.delorie.com/pub/djgpp/current/v2tk/lcms212b.zip library lcms2 2.12 pdf format documentation: ftp://ftp.delorie.com/pub/djgpp/current/v2tk/lcms212d.zip library lcms2 2.12 source: ftp://ftp.delorie.com/pub/djgpp/current/v2tk/lcms212s.zip Send library lcms2 specific bug reports to .
