Detailed Description

The QColorSpace class provides a color space abstraction.

Since: 5.14

\inmodule QtGui

Color values can be interpreted in different ways, and based on the interpretation can live in different spaces. We call this {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 for ColorModel::Rgb color spaces 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. For grayscale color spaces, only a single white primary is needed. The range of colors expressible 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.

Useful for gamma-corrected blending. \value AdobeRgb The Adobe RGB color space is a classic wide-gamut color space, using a gamma of 2.2. \l{http://www.color.org/chardata/rgb/adobergb.xalter}{ICC registration of Adobe RGB (1998)} \value DisplayP3 A color-space using the primaries of DCI-P3, but with the whitepoint and transfer function of sRGB.

◆ TransformModel

enum class QColorSpace::TransformModel : uint8_t

strong

Since: 6.8

Defines the processing model used for color space transforms.

\value ThreeComponentMatrix The transform consist of a matrix calculated from primaries and set of transfer functions for each color channel. This is very fast and used by all predefined color spaces. Any color space on this form is reversible and always both valid sources and targets. \value ElementListProcessing The transforms are one or two lists of processing elements that can do many things, each list only process either to the connection color space or from it. This is very flexible, but rather slow, and can only be set by reading ICC profiles (See \l fromIccProfile()). Since the two lists are separate a color space on this form can be a valid source, but not necessarily also a valid target. When changing either primaries or transfer function on a color space on this type it will reset to an empty ThreeComponentMatrix form.
