## What it is
A .NET/C# wrapper around Baidu's PaddleInference C API, providing PaddleOCR, PaddleDetection, rotation detection, Chinese segmentation, and Paddle2Onnx export. It ships native runtime packages via NuGet for Windows x64 (CPU and CUDA GPU) and Linux Ubuntu 22.04 x64.

## Use cases
- run OCR on images from C#
- recognize text in scanned pdfs or screenshots
- detect rotated or 180-degree text in images
- recognize tables in documents
- run object detection models like PPYolo in .NET
- segment Chinese text in C#
- convert Paddle models to ONNX

## When to choose
- you need OCR or Paddle model inference in a .NET application
- you want on-demand multilingual OCR model downloads with table and rotation support
- you have Windows x64 or Ubuntu 22.04 and want prebuilt native runtimes via NuGet

## When to avoid
- you need macOS, ARM, or other unsupported platforms
- you're not using .NET/C#
- you need a pure ONNX runtime solution without PaddleInference

## Facets
- artifact type: library
