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.

__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
