Hi Roger,
Thanks for let me know. I appreciate you Spanish, but since this is CC to the mailing list, and I think the subject may be interesting for other people as well, I would kindly continue the conversation in English. Hope this is ok to you :-) Ok, about DLL building, this should be easy. Just load the project into Visual studio. I will commit the 2013 project in few weeks, but 2010 does work as well as well in VS2013. Choose whatever 32 or 64 bits in the solution platform combo, choose release in the solution configuration combo, right click lcms2_dll project and select "build". This should be enough to compile and create the DLL. The binary of the DLL will be placed in the "bin" directory. Then for accessing the functions, those are using the _declspec(dllexport) convention, which is more or less the standard in windows DLL. I don't know much c#, but a sample interface could be like the free pascal one. You could locate this API interface in utils/delphi folder. I would not translate the full lcms2 API because as you already noted, it is huge! Instead, just open profile, create transform and do transform would be enough for many applications. Once you get this simple interface working, you could try more complex things. Converting single colors is like converting pixels. I would recommend the tutorial, if you can deal with the step-by-step example, I guess you would know how to translate colors. Please let me know any issues you would have. Good luck! Regards Marti. BTW, my first language is actually *catalan* wich is sort of half way between french and spanish. Never mind, it is cool you talk to me in spanish, though. :-D Quoting Roger Breton <gr...@videotron.ca>: > First of all, Maria, I want to recognize the COLOSSAL amount of trabajo that > LittleCMS represent -- es mas grande que la montana de Gilbraltar! > > It took me a while to get to donde estoy ahora.
