lzs4073/color

C++ library thats implemets class color. Available models: RGB, HSL, HSV, CMY, CMYK, YIQ, YUV and growing.

Yet another c++ library that implements color.

Status: Very close to the first milestone.

Key features:

• No virtual functions
• Minimal memory footprint
• Ability to copy array/vector of colours with memcpy, memmove, initialize with memset.
• Conversions from/to different types ( and its formats ).
• Headers only
• No third parties
• No additional binaries
• One file to include to start the fun
• Out of the box ready
• No need to recompile or start some install process.
• Color models: CMY, CMYK, GRAY, HSL, HSV, RGB, XYZ, YIQ, YUV.

Code sample:

        color::rgb<float>         f( { 1.0, 0.55, 0.0 } ); //!< This will pack ONLY three consecutive floats in memory
        color::rgb<std::uint8_t>  u( { 127,  255, 212 } ); //!< Three consecutive std::uint8_t.

        f = u; //!< Perform direct conversion from uint8_t to float.

        color::rgb<double>        d( { 0.1, 0.2, 0.3  } );

        f = d; //!< Reformat RGB from double to float
        u = f; //!< Reformat RGB from float to uint8_t

        color::hsl<std::uint8_t>  h( { 192, 64, 92  } );

        h = f; //!< This is the way how to convert from RGB(float) to HSL(std::uint8_t).

Available Color Formats

bool

Each component is one bool.

uint8_t

Each component will be type uint8_t. Usual color storing precision.

uint16_t

Each component will be type uint16_t. For more precision.

uint32_t

Each component will be type uint32_t. For higher.

uint64_t

Each component will be type uint64_t.For the highest precision in unsigned format.

float

Each component will be type float.

double

Each component will be type double.

long double

Each component will be type long double. Best precision of all.
