tukan

a C++ header-only color conversion- and computation-library

Features (Summary):

• almost complete <cmath>-implementation for linear RGB
• header only, no further dependencies except a C++11 compiler (or newer)
• no macros (except include guards)

RGB features:

• complete implementation of the C++11 <cmath> header, with the following exceptions:
• the macros NAN, INFINITY, HUGE_VAL, HUGE_VALF, HUGE_VALL are unimplemented (that's because macros cannot be overloaded)
• the classification functions (fpclassify, isfinite, isinf, isnan, isnormal, signbit) and comparison functions (isgreater, isgreaterequal, isless, islessequal, islessgreater, isunordered)

Planned features:

• almost lossless conversion of RGB colors to color spectrums (and back)
• sRGB from and to RGB
• HSV, CIE XYZ, YUV and all color spaces that exist (in the whole universe (and beyond))

RGB features:

• complete <cstdlib> math functions implementation
• <numeric_limits> implementation

"Can I participate?"

Yes. But beware that we strive for complete unit test coverage (I would assist with that). And all algorithms need citations (in the longer term).

The coding style in its essence reduces to clean, self-documenting, well-engineered and maintanable code. Users of this library should be able to use just the library sources for quick documentation lookup purposes. And release code must only depend on C++11 (incl. the standard library, of course). Compile time is a respected issue, too (remember: header only).

The code should be stable and portable (within C++11) as oops!

If this is all okay, you are very welcome, especially if you are an expert on some color space.
