We call this \e {color spaces}. + + QColorSpace provides access to creating several predefined color spaces and + can generate QColorTransforms for converting colors from one color space to + another. + + QColorSpace can also represent color spaces defined by ICC profiles or embedded + in images, that do not otherwise fit the predefined color spaces. + + A color space can generally speaking be conceived as a combination of set of primary + colors and a transfer function. The primaries defines the axes of the color space, and + the transfer function how values are mapped on the axes. + The primaries are defined by three primary colors that represent exactly how red, green, + and blue look in this particular color space, and a white color that represents where + and how bright pure white is. The range of colors expressable by the primary colors is + called the gamut, and a color space that can represent a wider range of colors is also + known as a wide-gamut color space. + + The transfer function or gamma curve determines how each component in the + color space is encoded. These are used because human perception does not operate + linearly, and the transfer functions try to ensure that colors will seem evenly + spaced to human eyes. +*/ + + +/*! + \enum QColorSpace::NamedColorSpace + + Predefined color spaces. + + \value SRgb The sRGB color space, which Qt operates in by default.
