23
A base class for plot print filters.
25
A print filter can be used to customize <a class="el" href="class_qwt_plot.html#d6270719d1ca5ac5952ab5e7fec3f84a">QwtPlot::print()</a>.<p>

<dl compact><dt><b><a class="el" href="deprecated.html#_deprecated000001">Deprecated:</a></b></dt><dd>In Qwt 5.0 the design of <a class="el" href="class_qwt_plot.html">QwtPlot</a> allows/recommends writing individual QwtPlotItems, that are not known to <a class="el" href="class_qwt_plot_print_filter.html">QwtPlotPrintFilter</a>. So this concept is outdated and <a class="el" href="class_qwt_plot_print_filter.html">QwtPlotPrintFilter</a> will be removed/replaced in Qwt 6.x. </dd></dl>
