自动化脚本必备PDF查看器精选

适用于自动化脚本的PDF查看器

在自动化脚本开发中，选择合适的PDF查看器至关重要。这类工具需要支持脚本调用、批量处理以及API或命令行接口，以实现高效的文件解析、内容提取或格式转换。

开源工具：PDF.js与PyMuPDF

PDF.js由Mozilla开发，基于JavaScript，适合Web环境下的自动化操作。其API允许从PDF中提取文本、图像或渲染页面为Canvas对象。PyMuPDF（又名fitz）是Python库，提供高性能的PDF解析功能，支持文本搜索、注释修改和元数据操作。

import fitz
doc = fitz.open("example.pdf")
text = doc.load_page(0).get_text()
print(text)

商业解决方案：Adobe Acrobat DC

Adobe Acrobat DC提供完整的自动化支持，包括JavaScript脚本和命令行工具。其Action Wizard功能可录制操作流程并批量处理文件，适合企业级需求。通过Interapplication Communication (IAC)接口，还能与其他程序集成。

命令行工具：pdftk与Ghostscript

pdftk（PDF Toolkit）通过命令行实现合并、拆分或加密PDF文件。Ghostscript则专注于格式转换和打印控制，支持将PDF转为图像或其他文档格式。

pdftk input.pdf cat 1-3 output chapter1.pdf
gs -dNOPAUSE -sDEVICE=png16m -r300 -o page_%d.png input.pdf

跨平台库：Apache PDFBox

Java开发的Apache PDFBox允许创建、编辑和提取PDF内容。其OCR功能结合Tesseract可处理扫描版文档，适合需要文本识别的自动化场景。

PDDocument document = PDDocument.load(new File("document.pdf"));
PDFTextStripper stripper = new PDFTextStripper();
String text = stripper.getText(document);
document.close();

云服务API：AWS Textract与Google Document AI

对于云端自动化，AWS Textract和Google Document AI提供RESTful API，能解析复杂表格和手写体。适合分布式系统或需要扩展性的场景，但需注意网络延迟和成本问题。

选择工具时需评估脚本语言兼容性、处理速度和功能覆盖范围。开源方案适合轻量级需求，而商业软件在稳定性和支持上更具优势。
