Re: [Discuss-gnuradio] Is there any way to export Qt GUI Sink?

[Marcus Müller]

Hello Shilei Tian!

When you middle-mouse-button-click on a Qt GUI, you get a menu, and that contains a "Save" entry. (You can definitely call that same functionality programmatically, too, but I'd have to look up how – I'd expect you'd have to send the right Qt signal to the right Qt slot to trigger the action, or you can grab the same data as that save function saves to disk).

However, that won't have a better quality than the screenshot, normally – the image is rendered as pixels, not as vector graphics, normally.

But you're on the right track:

If you want offline analysis, having something like the file sink might be the easiest approach.

Best regards,
Marcus

Hello, everyone.

I need the plot of Qt GUI Sink result, but I don’t find any way to export it except using system sceenshot, but it is  poor quality. I want to ask is there any way to export a vector figure, like *.eps or something else, or some data that I can use to plot with Matlab? Thanks!

Sincerely yours,
