Export Color PDF (Combined)

One plugin that exports the current document as a full-color PDF, for all three Supernote document types — auto-detected. Replaces the separate ExportColorPDF (notes/PDF) and ExportEPUBtoColorPDF plugins.

Per-stroke colours come from the Custom Color Palette plugin's sidecar ({EXPORT}/.ccp/{base}_colors.json). Output: {EXPORT}/color_{base}_{mode}_{stamp}.pdf, one PDF page per document page.

Flow

1. Chooser (full-screen): pick a page scope —
   • Annotated pages only — pages that carry marks.
   • Pages with new annotations — annotated pages whose stroke count grew since the last export (snapshot in {base}_exportstate.json; the SDK has no per-stroke timestamp, so "new" is relative to your last export).
   • Entire document — every page (MAX_PAGES, 0 = all).
2. Detect type from the file path.
3. Render + colour per page, then assemble a multi-page PDF.

Per-type pipeline (src/exporter.js)

Type	Base render	Colour overlay
.note	PluginFileAPI.generateNotePng	overlayColoredStrokes — distance-band tint (opaque pen) / wash (marker), EMR→pixel segments
.pdf	native renderDocPage (Android PdfRenderer)	drawColoredShapes — fill annotation contours on top
.epub / other doc	PluginDocAPI.generateDocImage	drawColoredShapes

Shared: colour resolution (byUuid → byIndex → legacy ARGB → penPrefs) and the colour-driven wash rule (marker, penType 11, + a highlighter colour → wash; everything else opaque). Annotated pages come from getMarkPages for docs; for notes, any page with ≥1 element.

Source

• index.js — registers the toolbar button (showType:1) and emits colorPdfExportReset on each press so the chooser re-arms (PluginHost re-shows the same component without remounting; closePluginView only hides it).
• src/App.tsx — chooser UI + progress + result (shows detected type).
• src/exporter.js — runExport({mode, onProgress}): detect type, select pages, render+colour, assemble, refresh the new-annotations snapshot.
• android/.../ColorPdfRendererModule.kt — native module CombinedColorPdfRenderer: overlayColoredStrokes, renderDocPage, drawColoredShapes, assemblePdf, pngInfo, readFile/writeFile.

Distinct identity (pluginID ecpc01combinedv1xm, applicationId com.exportcolorpdfcombined, native module CombinedColorPdfRenderer) so it coexists with the two originals during testing.
