Is there a way to save a QwtPlot as an image, e.g. as a PNG file?
Thanks
Gib
I should add that I'm using Qwt5.2.1. I see that qwt_plot_renderer is available in Qwt6, but not in Qwt5.
Now I see (from Uwe's reply to an old question) that the Bode plot example shows how to do it.
And now I see that this example creates a SVG image file, not exactly what I want. It uses QSvgGenerator, and there is nothing equivalent for other image formats.
