I have been working a method of saving the waterfall display canvas to a png file. For now, I have added it to the right click menu, but a keyboard shortcut would be another way.
Currently, the file is saved with a few minutes of historical waterfall at the zoom level being viewed. The filename is the frequency range and an arrow points to the frequency the mouse was on when the right click was pressed, making it easy to highlight something special.
I did it for me, but I am wondering about the interest in this feature in general. I was surprised not to see it on the bug/improvements list already.
Anyone else interested?
And for you Linux gurus or John, is there a quick way to make the server include a single revised file without making the entire project? I am not very conversant in Linux, I am afraid.
Also for John, I want to time stamp the waterfall. What is the best way to obtain the ADC time of the last line added to the waterfall canvas? Or any other line?
A sample from the top. The actual file is 1024x40000, so quite large.
