Screenshot command

[dlech]

It would be nice to be able to take a screenshot and upload it without using the command line.

@dlech Is there a particular way you were thinking of implementing this? Just fbgrab then download the file?

[dlech]

fbcat or fbgrab (I don't remember which) can pipe the image output to stdout, so we can actually use Device.exec() the extension and grab the stdout without having to ever create a file.

Oh, cool; I think it must be fbcat because I was looking for such an option on fbgrab earlier and couldn't find it. I'll look into this in a bit.

@dlech I was looking into the screenshot functionality last night; long story short, if we use fbcat, we get a PBM file (or PPM if you've hacked together a color display) which is obviously not ideal for a user. Would you prefer that I implement a parser+converter to generate a useful file type (would only take ten minutes to implement but would involve having a PNG or JPEG lib as a dependency) or use fbgrab and copy the file over via SSH? I think the former is cleaner but the latter involves less code on our end. Not sure which is more reliable.
