Problem applying QGraphicsBlurEffect to a QGraphicsPixmapItem

[ucomesdag]

Hi all,

I try to apply blur to an image but nothing seems to happen and can't wrap my head arround whatmight be wrong here:

QPixmap buffer(image.size());
QGraphicsPixmapItem item(buffer);
QGraphicsBlurEffect effect;
effect.setBlurHints(QGraphicsBlurEffect::QualityHint);
effect.setBlurRadius(5);
item.setGraphicsEffect(&effect);
 
item.pixmap().toImage().save("blur.png");

QPixmap buffer(image.size());
QGraphicsPixmapItem item(buffer);
QGraphicsBlurEffect effect;
effect.setBlurHints(QGraphicsBlurEffect::QualityHint);
effect.setBlurRadius(5);
item.setGraphicsEffect(&effect);

item.pixmap().toImage().save("blur.png");
