Feature Request: stop motion support

[hackerb9]

This app would be great for stop motion animation if it had a setting such that taking a photo also sets the static background so each new frame can be positioned relative to the last.

Nice, but not necessary extras:

• On launch (in stop motion mode) the background would be clear.
• New background when a photo is taken could be the composition (the preview) that had been shown on the screen rather than the photo file. This would not only be faster (smaller image size) but would add a fading trail effect so one can judge more accurately the direction and velocity of motion.

I'm working on this idea, but it's proving to be more challenging than I first thought. The camera preview isn't treated like a normal view, so when I try the screenshot method from here I get a black box where the preview should be. When I try a different method here using media projection and a virtual display I get a completely black screenshot.

I'll keep trying to implement it but it may take some time.

Could it be that the view is a ViewGroup? This method using view.getMeasuredHeight() might be relevant.

public static Bitmap getBitmapFromView(View view) {
    view.measure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED);
    Bitmap bitmap = Bitmap.createBitmap(view.getMeasuredWidth(), view.getMeasuredHeight(),
            Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());
    view.draw(canvas);
    return bitmap;
}
