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 So this concept is outdated and QwtPlotPrintFilter will be removed/replaced in Qwt 6.x.
