grabwidget image capturing problem

I am trying to capture the image of a QGraphicsView . I have used grabwidget to capture this image . I have written a small program and i successfully captured the image . But the problem is when i tried to integrate it with my product the image captured is not clear (dark lines and spots on the image ). Can anyone give me any siggestion on this.

Hi,

You can also render your Scene to a pixmap and save it. See for example:

Code:

---

QImage *image = new QImage(103,103,QImage::Format_RGB32); //Creates an image of a size 103x103 //Change for the size of your scene
    QRgb value;
    value = qRgb(255, 255, 255);
    image->fill(value); //Fill the image with white
    QPainter *painter = new QPainter(image); //Create a new painter based on the image
 
    //Renders the scene to the painter
    scene.render(painter);
 
    image.save("/home/cquiros/tnkicono.jpg","JPG"); //Saves the image

---

Depending on the file format, you will lose some image quality.

Hope it helps.
