C++ (Cpp) FilterInterface Examples

Example #1

File: filterdialog.cpp Project: KleineKarsten/FoundationsOfQtDev

 foreach( QObject *couldBeFilter, QPluginLoader::staticInstances() )
 {
   FilterInterface *filter = qobject_cast<FilterInterface*>( couldBeFilter );
   if( filter )
   {
     filters[ filter->name() ] = filter;
     ui.filterList->addItem( filter->name() );
   }
 }

Example #2

File: SoundWindow.cpp Project: janisozaur/pod-sound

void SoundWindow::applyFilter(QAction *action)
{
	FilterInterface *filter = mFiltersHash[action->data().value<QUuid>()];
	qDebug() << "filter name:" << filter->name();
	FilterData fd;
	fd.wav = *mWavDecoder;
	if (filter->setup(fd)) {
		DisplayWindow *dw = filter->apply(windowTitle());
		q_check_ptr(dw)->show();
	}
}

Example #3

File: main.cpp Project: weegreenblobbie/median_filter_benchmark

float run_timing_test(FilterInterface<T> & f)
{
    std::vector<float> timings;

    auto input = get_random_vector<T>(vector_size);

    for(unsigned i = 0; i < iterations; ++i)
    {
        auto t0 = now();

        auto out = f.filter(input);

        auto t1 = now();

        timings.push_back(delta(t1 - t0));
    }

    // compute average of timing values

    float avg = 0.0f;

    for(auto t : timings) avg += t;

    avg /= static_cast<float>(timings.size());

    return avg;
}
