I have a NW.js project and I'd like it to be able to save screenshots. However, the current method (using "request download") causes the app to ask the user where to save the file. My app would require that it saves without any prompt, so that no user intervention is required.
I found this tutorial, which sounded promising, but the result is a corrupted image.

Do you know why this tutoriel didn't work and how to fix it? Do you know other alternatives?
