ClearPDF Local v1.5.0 — Auto-flatten (hands-free book scanning)

The vFlat-style book flow is now complete: flip pages and flattened scans stack up on their own — no shutter taps, no per-page correction.

What's new

  • Auto-flatten toggle: when on, every captured page is run through the neural dewarp the moment it's captured. With Auto-scan + Auto-flatten both on, just hold the camera over an open book and flip — each curved page is auto-captured and flattened automatically.

Technical

  • addCapturedPhoto(autoFlatten) dewarps the raw photo then enhances it, caching the flattened image so a later mode switch doesn't re-run the model; falls back to the standard detect + perspective pipeline if dewarp fails.
  • Reuses the on-device-verified DewarpEngine (UVDoc via ONNX Runtime, ~275 ms/page) and OpenCV enhancement.
