Detailed Description

The KisVisualColorModel class allows manipulating a KoColor using various color models.

This enables different widgets to easily manipulate the same color representation (like HSV channels of an RGB color etc.) in a synchronized way without having to know the details of the underlying color space. NOTE: This class is meant to be shared between GUI classes using KisVisualColorModelSP, so DO NOT SET a QObject parent in this case.

sigChannelValuesChanged

void KisVisualColorModel::sigChannelValuesChanged ( const QVector4D & values, quint32 channelFlags )

signal

sigColorModelChanged

void KisVisualColorModel::sigColorModelChanged ( )

signal

sigColorModelChanged is emitted whenever the color model changes.

This can either be due to a change in color space that uses a different channel model, or when the same color space gets represented in a different way, for example RGB representation switches from HSV to HSL etc. so the values of sigChannelValuesChanged() change meaning. Note: This will be followed by sigChannelValuesChanged() unless caused by a color space change, new channel values are not available yet when this signal occurs.

sigColorSpaceChanged

sigColorSpaceChanged notifies that the color space from which the channel values are derived changed, and thus invalidating the current ones.
