我在 Mac OS X 上使用 Tesseract 和 Java 包装器库 Tess4J 运行了一个简单的程序。同时尝试了 JDK7 和 JDK8。
该代码对图像进行 OCR 并从中创建 PDF。该代码可以正常工作并完成它应该做的事情(pdf被创建得很好)。但最后,我在我的 Mac 上收到了崩溃报告。
private static void testTesseract() throws Exception {
File imageFile = new File("/Users/mln/Desktop/urkunde.jpg");
ITesseract instance = new Tesseract(); // JNA Interface Mapping
// http://tess4j.sourceforge.net/tutorial/
instance.setDatapath("/Users/mln/Desktop/tessdata");
instance.setLanguage("deu");
try {
String result = instance.doOCR(imageFile);
System.out.println(result);
} catch (TesseractException e) {
System.err.println(e.getMessage());
}
List<ITesseract.RenderedFormat> list = new ArrayList<ITesseract.RenderedFormat>();
list.add(ITesseract.RenderedFormat.PDF);
File pdfFile = new File("/Users/mln/Desktop/urkunde.jpg");
instance.createDocuments(pdfFile.getAbsolutePath(), "/Users/mln/Desktop/urkunde", list);
}
导致崩溃的行是最后一行:
instance.createDocuments(pdfFile.getAbsolutePath(), "/Users/mln/Desktop/urkunde", list);
控制台输出:
