CI / Windows build (push) Has been cancelled
Add pdfrx 2.4.4. PenCaptureRegion routes stylus to ink (arena-bypass via PenCaptureBinding) while touch falls through to pdfrx scroll/zoom. Spike pane hosts PdfViewer with page-overlay ink at normalized coords + frame-time HUD; reachable from home screen for on-device testing. Bench/coordinate harness under integration_test. Generated assets are gitignored (regenerate via tool/gen_*.dart).

|
|
// Standalone entry point for the THROWAWAY M1 pdfrx spike (plan §10).
|
|
//
|
|
// Launch on the Windows tablet (or any desktop with a display):
|
|
// flutter run -t lib/editor/pdf/spike_main.dart
|
|
//
|
|
// It opens test/assets/large_300p.pdf in [SpikeEditorPane] with the
|
|
// frame-timing HUD and ink-load toggle, so the M1 perf/pen gates are
|
|
// observable on-device.
|
|
//
|
|
// IMPORTANT: pen capture requires the kind-aware [PenCaptureBinding] (installed
|
|
// below before pdfrx init). pdfrx itself is initialized via
|
|
// pdfrxFlutterInitialize() — confirmed from pdfrx 2.4.4 example/pdf_combine.
