 # ScanSlicer (fork)
 
-ScanSlicer is a desktop Qt application (Python/PySide6) that detects multiple photos in a flatbed scan image, lets you correct each box manually, and exports perspective-corrected crops. It runs on Linux desktops over Wayland or X11.

 ## Changes from upstream
 
-- Fixed mirrored slice exports: added an explicit left/right orientation workflow with a **Swap L/R** button and color-coded left/right corners and edges.
-- Orientation corrections now persist through "squarize" and "reset rotation" (previously they were silently overwritten).
-- Hardened dependencies: switched to `opencv-python-headless`, removed the unused Pillow dependency, and made the AppImage build verify package hashes.
