.SH DESCRIPTION
The QPaintDeviceMetrics class provides information about a paint device.
.PP
Sometimes it is necessary to obtain information about the physical size of a paint device when drawing graphics.
.PP
Example:
.PP
.nf
.br
    QPaintDeviceMetrics pdm( myWidget );
.br
    double aspect = (double)pdm.widthMM / (double)pdm.heightMM();
.fi
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QPaintDeviceMetrics::QPaintDeviceMetrics ( const QPaintDevice * pd )"
Constructs a metric for the paint device \fIpd.\fR
.SH "int QPaintDeviceMetrics::depth () const"
Returns the bit depth (number of bit planes) of the paint device.
.SH "int QPaintDeviceMetrics::height () const"
Returns the height of the paint device, in default coordinate system units (e.g. pixels for QPixmap and QWidget).
.SH "int QPaintDeviceMetrics::heightMM () const"
Returns the height of the paint device, measured in millimeters.
.SH "int QPaintDeviceMetrics::numColors () const"
Returns the number of different colors available for the paint device.
.SH "int QPaintDeviceMetrics::width () const"
Returns the width of the paint device, in default coordinate system units (e.g. pixels for QPixmap and QWidget).
.SH "int QPaintDeviceMetrics::widthMM () const"
Returns the width of the paint device, measured in millimeters.
