◆ pixmapDevicePixelRatio()

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

Computes the displayDevicePixelRatio for a pixmap.

If displayDevicePixelRatio is 1.0 the returned 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)
