◆ multithreadedSteps()

QList< int > Digikam::DImgThreadedFilter::multithreadedSteps	(	int	stop,
		int	start = `0`
	)		const

inherited

This method return a list of steps to process parallelized operation in filter using QtConcurrents API. Usually, start and stop are rows or columns from image to process. By default, whole image will be processed and start value is 0. In this case stop will be last row or column to process. Between range [start,stop], this method will divide by equal steps depending of number of CPU cores available. To be sure that all values will be processed, in case of CPU core division give rest, the last step compensate the difference. See Blur filter loop implementation for example to see how to use this method with QtConcurrents API.

References Digikam::DynamicThread::start(), and Digikam::DynamicThread::stop().

◆ parametersSuccessfullyRead()

bool Digikam::DImgThreadedFilter::parametersSuccessfullyRead ( ) const

virtualinherited

Optional: error handling for readParameters. When readParameters() has been called, this method will return true if the call was successful, and false if not. If returning false, readParametersError() will give an error message. The default implementation always returns success. You only need to reimplement when a filter is likely to fail in a different environment, e.g. depending on availability of installed files. These methods have an undefined return value if readParameters() was not called previously.

Reimplemented in Digikam::IccTransformFilter.

◆ shutDown()

void Digikam::DynamicThread::shutDown ( )

protectedinherited

If you are deleting data in your destructor which is accessed from the thread, do one of the following from your destructor to guarantee a safe shutdown: 1) Call this method 2) Call stop() and wait(), knowing that nothing will call start() anymore after this 3) Be sure the thread will never be running at destruction. Note: This irrevocably stops this object. Note: It is not sufficient that your parent class does this. Calling this method, or providing one of the above mentioned equivalent guarantees, must be done by every single last class in the hierarchy with an implemented destructor deleting data. (the base class destructor is always called after the derived class)
