Detailed Description

A base class for plot print filters.

A print filter can be used to customize QwtPlot::print().

Deprecated:

In Qwt 5.0 the design of QwtPlot allows/recommends writing individual QwtPlotItems, that are not known to QwtPlotPrintFilter. So this concept is outdated and QwtPlotPrintFilter will be removed/replaced in Qwt 6.x.
