Well… any usual conversion from UTF-16 to char* (not sure if you expect to
store UTF-8 or whatever else encoding, I also don’t remember from the top of my
head which encoding libpng/the PNG specification expects).
This is a bit off-topic for lcms ☺ You should find plenty of options on google.

Cool. So, this gives an array of wchar_t.
I need to pass this to libpng, which is expecting a pointer to char.
Is there an easy way of converting?
Thanks

Not sure if it’s the best way, here’s a sniplet of what I was using once to get
the display name (C++11):
// assuming you have the profile open – hprofile is the handle to the profile
cmsUInt32Number bufferSize = cmsGetProfileInfo(hprofile, cmsInfoDescription,
cmsNoLanguage, cmsNoCountry, nullptr, 0);
size_t numWideChars = (bufferSize + 1) / 2;
std::unique_ptr<wchar_t[]> description(new wchar_t[numWideChars]);
cmsUInt32Number result = cmsGetProfileInfo(hprofile, cmsInfoDescription,
cmsNoLanguage, cmsNoCountry, description.get(), bufferSize);
Note that you might want to check if the profile name is available a certain
language….
You also could directly store it to a pre-sized std::wstring rather than the
unique_ptr<wchar_t[]>; I don’t remember why Idid it that way.

Hello Again,
What is the best way of using lcms to extract an ICC profile name?
Thanks so much,
Aaron
