◆ pixmapDevicePixelRatio()

qreal QIconPrivate::pixmapDevicePixelRatio	(	qreal	displayDevicePixelRatio,
		const QSize &	requestedSize,
		const QSize &	actualSize
	)

Computes the displayDevicePixelRatio for a pixmap.

If displayDevicePixelRatio is 1.0 the reurned value is 1.0, always.

For a displayDevicePixelRatio of 2.0 the returned value will be between 1.0 and 2.0, depending on requestedSize and actualsize: If actualsize < requestedSize : 1.0 (not enough pixels for a normal-dpi pixmap) If actualsize == requestedSize * 2.0 : 2.0 (enough pixels for a high-dpi pixmap) else : a scaled value between 1.0 and 2.0. (pixel count is between normal-dpi and high-dpi)
