Transition from Qt4 to Qt5: one overloaded version of QPainter:drawPixmapFragments absent in Qt5

qt4_to_qt5

void drawPixmapFragments(QPainter *painter, const QRectF *targetRects, const QRectF *sourceRects, int fragmentCount,
	const QPixmap &pixmap, QPainter::PixmapFragmentHints hints)
{
	for (int i = 0; i < fragmentCount; ++i) {
		QRectF sourceRect = (sourceRects) ? sourceRects[i] : pixmap.rect();

		QPainter::PixmapFragment pixmapFragment =
			QPainter::PixmapFragment::create(
				targetRects[i].center(),
				sourceRects[i],
				targetRects[i].width() / sourceRect.width(),
				targetRects[i].height() / sourceRect.height()
			);

		painter->drawPixmapFragments(&pixmapFragment, 1, pixmap, hints);
	}
}

In Qt5 the function QPainter::drawPixmapFragments with five arguments was deprecated:

void QPainter::drawPixmapFragments(const QRectF *targetRects, const QRectF *sourceRects, int fragmentCount,
const QPixmap &pixmap, QPainter::PixmapFragmentHints hints)

This function does not exists in Qt5.

This gist is the helper for transition, call it as before in Qt4, but first parameter is the pointer to your QPainter instance.
