I want to apply the cine of series image inside my project?

amarism

I have a series of image loaded inside the viewport. Now, I want to take a button and when i click the button all the slices of series changing to FPS(frame per second). I dont have enough idea abot how to do this.
I will used this code for move slider infinite time:-

connect is used for tranfering the signal when button is pressed.

connect(this->ui->m_cine, SIGNAL(pressed()), this, SLOT(AnimatedSlider()));

this Function is the working function infinite loop:-

void QtVTKRenderWindows::AnimatedSlider()
{
QPropertyAnimation *animation = new QPropertyAnimation(slider, "sliderPosition");
animation->setDuration(1000);
animation->setStartValue(slider->minimum());
animation->setEndValue(slider->maximum());
animation->setEasingCurve(QEasingCurve::OutCubic);
animation->setLoopCount(-1);
animation->start();
}

But i am getting problem like when i set the loop count to -1. It will goes to finite time

Any help is considerable
Thank you

Hi,

One thing that is not good is that you are creating a new animation each time you call AnimatedSlider. You should likely create it once and only update its parameter and start it in AnimatedSlider.

@SGaist Slider is moving but the problem is coming is once the slider reached to maximum point. then it will be stop .But i want to set the slider like that once it will reached to maximum point then again slider comes to the initial point.

SGaist

So you should use something like:

animation->setKeyValueAt(0, slider->minimum());
animation->setKeyValueAt(0.5, slider->maximum());
animation->setKeyValueAt(1, slider->minimum());

and remove the setStartValue and setEndValue calls.

@SGaist i am getting the slider movement.. open more problem comes is .. when i will moving the cine in loop by increasing the slider one by oen but it will be move not one by one. How to fix this

SGaist

I don't understand that statement. Can you rephrase it or show an example of what is happening ?

@SGaist On button click slider move like cine play . but every slice of image not show .Like it will skip slice of image .
I am taking the trigger signal when the move

connect(sliter, SIGNAL(valueChanged(int)), SLOT(slider_Event(int)));

And i am invoking the signal here.when the slider is move from one slice to another slice.

 void QtVTKRenderWindows::slider_Event(int index)
{
int pos =slider->sliderPosition();
RadSpaViewer->m_VtkImageSlicing(pos, 2);
}

this function is work for displaying the next slice

 m_VtkImageSlicing(sliderposition,sliderNumber)

SGaist

Is the slider max value accurate ?

amarism

@SGaist yes we are taking the series minimum and maximum value and fixed it here

animation->setStartValue(minimumSliderValue);
animation->setEndValue(maximumSliderValue);

SGaist

What are these values ?

amarism

@SGaist Series minimum value is (minimumSliderValue) and maximum value is (maximumSliderValue) . Like total how many slice are there inside the series. For example series has 52 slices then minimumSliderValue = 0, and maximumSliderValue = 52.

SGaist

Did you set the singleStep to 1 ?

Also, did you check the value you receiving in that slot ?
