Hi, is it possible to save the plot as an image. I could not find any clear example for that. thanks.

rafaelmizrahi commented 2 years ago

I see that the draw function returns a reference to a buffer. I have successfully saved it as an image. I managed so by changing view_ into public and mimicking part of the code inside Figure::show

please let me know your official answer of how to support saving plots as images.

Hi @rafaelmizrahi, thank you for opening an issue. I added Figure::drawFile in #27, which draws the figure on a Mat of given size and writes it as PNG. See FigureTest for an example. Is this what you were looking for?

Can we save the whole Window as image instead of single Figure?
