RapidOCR 📄 PDF
### 简介
本仓库依托于[RapidOCR](https://github.com/RapidAI/RapidOCR)仓库，快速提取PDF中文字，包括扫描版PDF、加密版PDF、可直接复制文字版PDF。
🔥🔥🔥 版式还原参见项目：[RapidLayoutRecover](https://github.com/RapidAI/RapidLayoutRecover)
### 整体流程
```mermaid

A(PDF) --> B{是否可以直接提取内容} --是--> C(PyMuPDF)
B --否--> D(RapidOCR)
C & D --> E(结果)
```
### 安装
```bash
# 基于CPU 依赖rapidocr_onnxruntime
pip install rapidocr_pdf[onnxruntime]
# 基于CPU 依赖rapidocr_openvino 更快
pip install rapidocr_pdf[openvino]
# 基于GPU 依赖rapidocr_paddle
pip install rapidocr_pdf[paddle]
```
### 使用
脚本使用
```python
from rapidocr_pdf import PDFExtracter
pdf_extracter = PDFExtracter()
pdf_path = 'tests/test_files/direct_and_image.pdf'
texts = pdf_extracter(pdf_path, force_ocr=False)
print(texts)
```
命令行使用
```bash
$ rapidocr_pdf -h
usage: rapidocr_pdf [-h] [-path FILE_PATH] [-f]
optional arguments:
-h, --help show this help message and exit
-path FILE_PATH, --file_path FILE_PATH
File path, PDF or images
-f, --force_ocr Whether to use ocr for all pages.
$ rapidocr_pdf -path tests/test_files/direct_and_image.pdf
```
### 输入输出说明
**输入**：`Union[str, Path, bytes]`
**输出**：`List` \[**页码**, **文本内容**, **置信度**\]， 具体参见下例：
```python
[
['0', '人之初，性本善。性相近，习相远。', '0.8969868'],
['1', 'Men at their birth, are naturally good.', '0.8969868'],
]
```
