Constructor & Destructor Documentation

◆ CurvesContainer() [1/2]

Digikam::CurvesContainer::CurvesContainer ( )

Provides a convenient storage for a curve. Initially, the values are empty. Call initialize() before adjusting values manually.

◆ initialize()

void Digikam::CurvesContainer::initialize ( )

Fills the values with a linear curve suitable for type and sixteenBit parameters.

◆ isEmpty()

bool Digikam::CurvesContainer::isEmpty ( ) const

An empty container is interpreted as a linear curve. A non-empty container can also be linear; test for isLinear() of the resulting ImageCurves. Note: If an ImageCurves is linear, it will return an empty container.

◆ isStoredLosslessly()

bool Digikam::CurvesContainer::isStoredLosslessly ( ) const

Serialize from and to FilterAction. isStoredLosslessly returns false if the curve cannot be losslessly stored in XML because it would be too large (free 16 bit). It is then lossily compressed.
