静音打印时Mac上的PDFBox严重错误 [英] PDFBox on Mac critical error when silent printing
问题描述
我一直在尝试将对PDFBox的应用程序依赖性提高到2.0.0快照. 我在遇到一些重大问题...
I have been experimenting with bumping my applications dependency on PDFBox to the 2.0.0 snapshot. I'm having some major issues with it though...
因此，我的代码将PDF接收为BASE64字符串，我对其进行了解码，然后将结果字节数组加载到PDDocument中.在更改版本号之前，在PDDocument上调用.silentPrint();就像一个超级按钮.
So my code recieves a PDF as a BASE64 String, i decode it, and load the resulting bytearray into a PDDocument. Before I bumped the version number, calling .silentPrint();on the PDDocument worked like a charm.
静默打印的实现在2.0.0中进行了更改，现在我是这样进行的:
The implementation of silent printing changed in 2.0.0, and I now do it this way:
private Status doPdfPrint(Document document, PrintService printService) {
ByteArrayInputStream bais = null;
PDDocument doc = null;
PrinterJob printerJob = PrinterJob.getPrinterJob();
try {
printerJob.setPrintService(printService);
bais = new ByteArrayInputStream(document.getDecodedData());
doc = PDDocument.load(bais, true); //Force load
PDFPrinter pdfPrinter = new PDFPrinter(doc);
pdfPrinter.silentPrint(printerJob);
doc.close();
bais.close();
} catch (IOException | PrinterException e) {
log.warn("Failed to print! Exception occurred: {}", e.getMessage());
log.debug("EXCEPTION", e);
return Status.PRINTING_FAILED;
} finally {
IOUtils.closeQuietly(bais);
IOUtils.closeQuietly(doc);
}
return Status.PRINTING_OK;
}
但是，在OSX Yosemite上运行时，结果为:
However, when running this on OSX Yosemite, this results in:

知道发生了什么吗? 问候
Any idea what's going on? Regards
推荐答案
因此，我是在第一次发生这种情况2年后发布在这里的.
So I'm posting here 2 years after this occured for the first time..
它仍在发生.但是，这是Java错误，而不是PDFBox错误.因此，在将错误报告提交到PDFBox问题跟踪器之后，我得到了建议，在进行打印时为文档设置DPI.瞧，它有效.但是，要弄清楚pdf文档的DPI几乎是不可能的.
It's still occuring. However, it's a Java bug, rather then a PDFBox bug. So after filing my bugreport on PDFBox issue-tracker, I got the advice to set a DPI for the document when doing printing. And voila it works. However, it's nearly impossible to figure out the DPI of a pdf document.
但是，如果您知道DPI是什么，则只需执行以下操作:
However, if you know what the DPI is, you can simply do this:
final int rasterizedDpi = 203;
final PDDocument pdfDocument = PDDocument.load(data);
final PrinterJob job = PrinterJob.getPrinterJob();
final PDFPageable pageable = new PDFPageable(pdfDocument, Orientation.AUTO, false, rasterizedDpi);
job.setPageable(pageable);
job.print();
这里的提示是PDFPageable的第四个参数dpi ...
The hint here is the 4th argument to PDFPageable, the dpi...
在Oracle修复此JDK错误之前，我想我们将不得不调用此方法:)
Until Oracle fixes this JDK bug, i guess we're going to have to call this method :)
