Hello, I don't know if I'm in the right section, but I'm looking for a software that enables you to export an waveform(the standard, osciloscope one) to an image format(JPG, PNG, etc.).

thanks in advance
 
On a PC you just push the Print Screen button and then open most any graphics program and paste (Ctrl-V) it in, then save. I usually just use Windows built in Paint for this. This saves the whole display on your screen. If you just want to capture one window you hold the Alt button down while pressing Print Screen. Macs have a similar function that will automatically send it to the desktop without having to paste it into a graphics editor, and it has an option for selecting the exact area to capture. I forget exactly what you do to make this happen but it's pretty commonly known among Mac people.
 
Print screen is a good solution, but I need high resolution images for print

thanks for answering

Print Screen captures images at the resolution of your monitor. If you magnify the waveform view in your software you'll get very high resolution capture. After pasting into Paint you can save to bitmap for uncompressed images.
 
Vista and W7 have 'Snipping Tool' in Accessories. Jing is a free download that also snapshots certain parts of screen.
 
I could see where the print screen option could be inadequate for this.

What if you want the entire waveform as a single high-res photo? You'd have to take dozens of screenshots and comp them together. A tool that could generate the images from .wav files would be cool.

It would depend on how big your finished print of the wav was going to be, but really, for most practical purposes it would only be comping four slices together.
Assuming the screen is 72dpi.
Print resolution is 300dpi.

So you'd need to make your screen image about 4 times the size, so that when you opened it up in your photo editor, you could reduce the picture size by 4 times, thereby increasing the effective resolution of the image you'd captured at 72dpi to 300dpi. :)
