java项目处理OFD文件

一、导入 jar 依赖包
1.1 Maven 项目引入 jar 包

<dependency>
    <groupId>org.ofdrw</groupId>
    <artifactId>ofdrw-converter</artifactId>
    <version>2.0.2</version>
</dependency>

二、实现思路

1、直接解析ofd获取其内容,在此不多述

2、走OCR识别

1)ofd转pdf,pdf再转图片,图片走OCR识别

Path ofdPath = Paths.get("D:/ofd/1.ofd");
Path pdfPath = Paths.get("D:/ofd/target/1.pdf");
try (OFDExporter exporter = new PDFExporterPDFBox(ofdPath, pdfPath)) {
    exporter.export();
} catch (IOException e) {
    e.printStackTrace();
}

结论:出现了下述的重影问题,转PDF效果太差。所以该方案取消

 

2)ofd转图片,图片走OCR识别

Path ofdPath = Paths.get("D:/ofd/1.ofd");
Path imgPath = Paths.get("D:/ofd/img");
try (ImageExporter exporter = new ImageExporter(ofdPath, imgPath, "PNG", 20d)) {
    exporter.export();
} catch (IOException e) {
    e.printStackTrace();
}

结论:测试了多个ofd文件,转换图片效果较好
