| QColor | map (const QColor & color ) const |
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.
應用顔色變換在 QRgb 值 argb .
The input should be opaque or unpremultiplied.
應用顔色變換在 QRgba64 值 rgba64 .
The input should be opaque or unpremultiplied.
應用顔色變換在 QColor 值 color .
