<hr/><a name="_details"></a><h2>Detailed Description</h2>
<div class="textblock"><p>A Map to translate between layout, screen and paint device metrics. </p>
<p>Qt3 supports painting in integer coordinates only. Therefore it is not possible to scale the layout in screen coordinates to layouts in higher resolutions ( f.e printing ) without losing the higher precision. <a class="el" href="class_qwt_metrics_map.html" title="A Map to translate between layout, screen and paint device metrics.">QwtMetricsMap</a> is used to incorporate the various widget attributes ( always in screen resolution ) into the layout/printing code of <a class="el" href="class_qwt_plot.html" title="A 2-D plotting widget.">QwtPlot</a>.</p>
<p>Qt4 is able to paint floating point based coordinates, what makes it possible always to render in screen coordinates ( with a common scale factor ). <a class="el" href="class_qwt_metrics_map.html" title="A Map to translate between layout, screen and paint device metrics.">QwtMetricsMap</a> will be obsolete as soon as Qt3 support has been dropped ( Qwt 6.x ). </p>
