QColorTransform is an instantiation of a transformation between color spaces. It can be applied on color and pixels to convert them from one color space to another.
Setting up a QColorTransform takes some preprocessing, so keeping around QColorTransforms that you need often is recommended, instead of generating them on the fly.

bool QColorTransform::isIdentity() const
\since
6.4 Returns true if the color transform is the identity transform.
QRgb QColorTransform::map(QRgb argb) const
Applies the color transformation on the QRgb value argb.
The input should be opaque or unpremultiplied.
QRgba64 QColorTransform::map(QRgba64 rgba64) const
Applies the color transformation on the QRgba64 value rgba64.
The input should be opaque or unpremultiplied.
QRgbaFloat16 QColorTransform::map(QRgbaFloat16 rgbafp16) const
Applies the color transformation on the QRgbaFloat16 value rgbafp16.
The input should be opaque or unpremultiplied. \since
6.4
QRgbaFloat32 QColorTransform::map(QRgbaFloat32 rgbafp32) const
Applies the color transformation on the QRgbaFloat32 value rgbafp32.
The input should be opaque or unpremultiplied. \since
6.4
QColor QColorTransform::map(const QColor &color) const
Applies the color transformation on the QColor value color.

bool operator!=(const QColorTransform &ct1, const QColorTransform &ct2)
\since
6.4 Returns true if ct1 does not define the same transformation as ct2.
bool operator==(const QColorTransform &ct1, const QColorTransform &ct2)
\since
6.4 Returns true if ct1 defines the same color transformation as ct2.
