<p>The number of logical pixels per millimeter. This is the effective pixel density provided by the platform to use in image scaling calculations.</p>
<p>Due to inconsistencies in how logical pixel density is handled across the various platforms Qt supports, it is recommended to use physical pixels instead (via the <code>pixelDensity</code> property) for portability.</p>
<p>This property was introduced in Qt 5.1.</p>
