How I can quickly save QML animation to file?

komar_rus

I have the following QML:
@
import Qt 4.7

Item {
width: 500
height: 500
Text {
id: idText1
x: 100
y: 100
color: "red"
text: "Hello word!"
font.pixelSize: 40

    SequentialAnimation {
        running: true
        NumberAnimation {target: idText1; properties: "x"; to: 0; duration:   1000 } 
        PauseAnimation {duration: 1000 }
        NumberAnimation {target: idText1; properties: "x"; to: 100;    duration: 1000 }
    }
}

}
@

The animation time is 3 seconds, but I want to save the result of anymation faster than 3 second, literaly saying I want it to be saved as fast as my processor can render it.

That is what is desired:

@
QGraphicsScene scene;
QDeclarativeEngine engine;
QDeclarativeComponent component(&engine, QUrl::fromLocalFile("QMLTest.qml"));
QGraphicsItem *pobject = qobject_cast<QGraphicsItem *>(component.create());
scene.addItem(pobject);

//My Code
scene.SetFrameRate(25.0);
//

for (int n = 0; n < 75; n++)
{
QImage qImage(500, 500, QImage::Format_ARGB32);
QPainter qPainter(&qImage);
scene.render(&qPainter);

//My Code
qAVIFileWriter.WriteImage(qImage);
//
}

veiw.show();
