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.

To create a QColorTransform , use transformationToColorSpace() :

QColorSpace sourceColorSpace(QColorSpace::SRgb);
QColorSpace targetColorSpace(QColorSpace::DisplayP3);
QColorTransform srgbToP3Transform = sourceColorSpace.transformationToColorSpace(targetColorSpace);

Setting up a QColorTransform takes some preprocessing, so keeping around QColorTransforms that you need often is recommended, instead of generating them on the fly.

__init__()¶

__init__(colorTransform)

Parameters:: colorTransform – QColorTransform

isIdentity()¶

Return type:: bool

Returns true if the color transform is the identity transform.

map(rgba64)¶

Parameters:: rgba64 – QRgba64
Return type:: QRgba64

Applies the color transformation on the QRgba64 value rgba64.

The input should be opaque or unpremultiplied.

map(color)

Parameters:: color – QColor
Return type:: QColor

Applies the color transformation on the QColor value color.

map(argb)

Parameters:: argb – int
Return type:: int

__ne__(ct2)¶

Parameters:: ct2 – QColorTransform
Return type:: bool

Returns true if ct1 does not define the same transformation as ct2.

__eq__(ct2)¶

Parameters:: ct2 – QColorTransform
Return type:: bool

Returns true if ct1 defines the same color transformation as ct2.

swap(other)¶

Parameters:: other – QColorTransform
