Webcam restore blocks CLI prompts

Screenshot of the problem is requested--author uses a tiling window manager and didn't think about this.

Do people find the preview useful? It can just be turned off entirely.

Here's a screenshot of my lovely ceiling immediately after the window opens: Screenshot_2022-03-25_18-21-16

As you can see, it fills the screen entirely.

A few thoughts on the matter:

• The preview window is a useful, and perhaps even essential part of the restoration process for the following reasons:

  • The window tells the user that a scanning program is actually running
  • It shows if the QR codes are in the image or if they are out of view of the webcam
  • It shows whether or not you are holding the paper too close (blurry) or too far away (program can't resolve the image).

• If possible, the size of the window should be adjusted to a reasonable value by default (maybe 640x480, I guess HiDPI monitors could have an issue with that), so that it is unlikely to cover the screen.

• Perhaps a message could pop up on the terminal telling the user "hey, a window will pop up on screen but we'll show you what's happening on the terminal so make sure to take a look at it as you scan your QR codes". The user could then "press any key to continue" before the preview pops up. This way, the user knows that the terminal window is still worth looking at while the preview window is open.

(Sorry for the delay in responding.)

As a note to myself, in v1.2 I'm going to add a built-in GUI with scanning previews. So this is only relevant for CLI restores, which is a bigger deal in v1.0 and v1.1.

I don't have a great way to resize or position the window. If you have bright ideas on how, please speak up!

I've added the message you suggest. Let me know if you have better wording suggestions.

==Webcam Restore==

In a second, a second window with a webcam preview will appear on screen.
You may need to resize or move the window to see this terminal.

Progress and hints will appear in the terminal.

Press Enter to start scanning codes.

I think the warning is sufficient. Once I knew what was happening, I knew how to deal with the problem.

Thanks for the update.
