Portable abstractions, models, controllers, rail-navigation, line detection, search, and annotation logic for RailReader.

Desktop PDFium implementations of Core interfaces plus filesystem-backed AppConfig, AnnotationService, ConsoleLogger, and LayoutModelLocator.

ONNX-backed ILayoutAnalyzer implementation using PP-DocLayoutV3 for document layout detection.

SkiaSharp rasterisation and IPdfServiceFactory implementation for desktop PDF rendering via PDFium.

OpenAI-compatible IVlmService implementation for RailReader. Works against any endpoint that speaks the OpenAI chat-completions protocol (OpenAI, Ollama, vLLM, etc.).

Pure-managed implementations of Core's PDF text/link/outline services using UglyToad.PdfPig. Targets web/mobile/Lite consumers that cannot ship PDFium. Parses only; rasterisation lives in a sibling renderer.

Pure-managed rasterisation for Lite/web/mobile consumers. Implements IPdfService and IPdfServiceFactory by composing RailReader.Core.PdfPig (parsing) with PdfPig.Rendering.Skia (rendering via SkiaSharp).... More information

PDF→Markdown export pipeline for RailReader. Composes the Core primitives (layout analysis, rendering, per-block VLM transcription) into a Markdown document, applying heading-level heuristics and per-block... More information

IOcrService implementation backed by RapidOcrNet (PaddleOCR PP-OCR ONNX models), for reading PDFs with no text layer.

Opt-in GPU acceleration for RailReader.Core.Analysis's layout analyzers via ONNX Runtime's native WebGPU plugin execution provider (Dawn -> D3D12/Vulkan/Metal).
