pixmap resize

[IknowQT]

Draw a chart and get a pixmap with chartview->grab().
Then, I want to expand the chart to fit the label, but I can't get a full screen. And the resolution is broken... Help me.

        this->ui.label_13->setAlignment(Qt::AlignCenter);
	this->ui.label_13->setFrameShape(QFrame::Box);
	this->ui.label_13->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding);
	this->ui.label_13->setBackgroundRole(QPalette::Base);
	this->ui.label_13->setAutoFillBackground(true);
	this->ui.label_13->setMinimumSize(132, 132);


void QReportForm::SetChartPixmap(QPixmap* pix)
{
	m_pPixmap = pix;
	this->ui.label_13->setPixmap(
		pix->scaled(
			this->ui.label_13->width(),
			this->ui.label_13->height(),
			Qt::KeepAspectRatio)
	);
}

1. It is unnecessary to use pointers for QPixmap so change to:

void QReportForm::SetChartPixmap(const QPixmap & pix)
{
    ui.label_13->setPixmap(pix);
}

2. Use the scaledContents property: ui.label_13->setScaledContents(true);

you generate svg image to fit the full screen without losing resolution. Do not create pixmap.
