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:

colorTransformQColorTransform

isIdentity()#
Return type:

bool

Returns true if the color transform is the identity transform.

map(rgba64)#
Parameters:

rgba64QRgba64

Return type:

QRgba64

QColor

Applies the color transformation on the QColor value color.

map(argb)
Parameters:

argb – int

Return type:

int

__ne__(ct2)#
Parameters:

ct2QColorTransform

Return type:

bool

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

__eq__(ct2)#
Parameters:

ct2QColorTransform

Return type:

bool

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

swap(other)#
Parameters:

otherQColorTransform
