Hi
its unclear what you try
pix.scaled(width(), height(), << what are those sizes , its not push button.

so you try to take image and clip it to round avatar image , much like here at Qt forum ?

if you actually wan‘t a fadeIn/fadeOut transition of 2 pixmaps, i believe you can do that via QProppertyAnimations that targets the opacity as Property

thanks for your reply problem is sloved

QPixmap pix;
pix.loadFromData(image_data);
int size = qMax(pix.width(), pix.height());
QPixmap rounded = QPixmap(size, size);
rounded.fill(Qt::transparent);
QPainterPath path;
path.addEllipse(rounded.rect());
QPainter painter(&rounded);
painter.setClipPath(path);
painter.fillRect(rounded.rect(), Qt::black);
int x = qAbs(pix.width() - size) / 2;
int y = qAbs(pix.height() - size) / 2;
painter.drawPixmap(x, y, pix.width(), pix.height(), pix);
ui->pushButton_4->setIcon(QIcon(rounded));
