PDF到Multipage TIFF（pdfbox / icafe4j） - 在Windows上运行，在Linux上出错

时间：2017-12-06 14:15:38

标签： java linux pdfbox tiff multipage

我们在SAP PI（7.40）环境中遇到问题。我们从不同的接口获得发票（xml，csv，pdf），在此过程中我们必须发送一个tiff文件（从pdf通过pdfbox / icafe4j转换）到OCR提供商。 pdf可以是：

  1. 传入的pdf
  2. 由我们自己生成的pdf（通过pdfbox，来自xml或csv输入）。

    3. 转换是在外部java类中实现的。它适用于大多数pdf文件。只有少数pdf文件，我们在SAP PI环境中得到异常，在Linux（!!）上运行。 在本地 Windows（!!）环境中，相同的转化运行精细，没有任何错误。

    Linux环境的部分例外：

    <?xml version="1.0" encoding="ISO-8859-1"?>
<ErrorHandling>
<ExceptionType>class java.lang.IndexOutOfBoundsException</ExceptionType
<ExceptionLocalizedMsg>Index: 0, Size: 0</ExceptionLocalizedMsg>
....

    摘自java实现：

    // pDoc is the PDDocument object, returns byte[]
bTiff = tiffFromPdf.createMultipageTIFF(pDoc);
sTiffBase64 = DatatypeConverter.printBase64Binary(bTiff);
this.fireTrace(1, "Content of sTiffBase64 -> [" + sTiffBase64 + "]");

// Trace 'normally' contains:
<Trace type="T" level="1">Content of sTiffBase64 -> [base64-encoded tiff data] </Trace>

// In createMultipageTIFF the exception occurs in this line
TIFFTweaker.writeMultipageTIFF(rout, param, images);

    在我们找到有关TIFFTweaker类更新的以下内容之后，我们实现了更新，之后不会抛出异常，但是如链接中提到的那样，它被吞下。

    https://github.com/dragon66/icafe/issues/63 

    // Trace of byte[] then is emtpy:
<Trace type="T" level="1">Content of sTiffBase64 -> [] </Trace>

    这不是很有用，因为我们必须有OCR的tiff文件。

    我们还看了一下pdf字节流的内部结构，发现有一些特殊的部件处理字体/编码： TrueType字体和＆＃34; /编码/ 标识-H ＆＃34; ...所有不在我们的Linux系统下运行的pdf文件都包含这个＆＃34; Identity-H ＆＃34;。

    有没有人在Linux上进行此转换时有类似的经验/错误？

    除了我们的尝试之外，还有什么可以做的吗？ 也许某些库在Linux或其他地方缺失了！？

    请同时查看此转换（可能有助于理解）：

    https://www.mail-archive.com/users@pdfbox.apache.org/msg09569.html

    我在没有任何代码或受影响的pdf文件的情况下开始此问题的初始条目，但如果需要，请提供。
