Detailed Description

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.

Member Function Documentation

QRgb QColorTransform::map(QRgb argb) const

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.

QColor QColorTransform::map(const QColor &color) const

Applies the color transformation on the QColor value color.
