| 21 | \brief A base class for plot print filters.
|
---|
| 22 |
|
---|
| 23 | A print filter can be used to customize QwtPlot::print().
|
---|
| 24 |
|
---|
| 25 | \deprecated In Qwt 5.0 the design of QwtPlot allows/recommends writing
|
---|
| 26 | individual QwtPlotItems, that are not known to QwtPlotPrintFilter.
|
---|
| 27 | So this concept is outdated and QwtPlotPrintFilter will be
|
---|
| 28 | removed/replaced in Qwt 6.x.
