tools/app.py (myscan/app.py, Qt/PySide6) shows the camera and the page as it is stitched, Start/Stop or the scan button (F5), then reads the finished page with RapidOCR (myscan/ocr.py; bundled multilingual models, offline). Lines are outlined on the page by confidence and linked to an editable text pane that can be copied or saved. Existing images can be opened or dropped, so the app is useful without the mouse. The scan loop moves from tools/scan.py to myscan/scanner.py, shared by both. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

"""Scan with the scan button, like the original app: press it to start, glide the
|
|
mouse over the page, press it again to stop. Frames are registered while you scan;
|
|
after the stop press the page is assembled from all of them at once (see
|
|
myscan/stitching/pagegraph.py) and saved as <outdir>/scan-YYYYmmdd-HHMMSS.png. The mouse goes
|
|
back to mouse mode between scans (and on Ctrl-C). The loop itself is myscan/scanner.py.
|
|
|
|
With --view, a browser viewer (myscan/webview.py) shows the camera and the page as it
|
|
is being stitched, and has Start/Stop buttons that work like the scan button."""
