.SH "Detailed Description"
.PP
A base class for plot print filters.
A print filter can be used to customize \fBQwtPlot::print()\fP.
.PP
\fBDeprecated\fP
.RS 4
In Qwt 5.0 the design of \fBQwtPlot\fP allows/recommends writing individual QwtPlotItems, that are not known to \fBQwtPlotPrintFilter\fP. So this concept is outdated and \fBQwtPlotPrintFilter\fP will be removed/replaced in Qwt 6.x.
