我能够使用PDFBox(版本1.8.9)创建PDF,然后使用以下代码将其转换为PostScript文件:
DocFlavor flavor = DocFlavor.SERVICE_FORMATTED.PRINTABLE;
StreamPrintServiceFactory[] factories =
StreamPrintServiceFactory.lookupStreamPrintServiceFactories(flavor,
DocFlavor.BYTE_ARRAY.POSTSCRIPT.getMimeType());
if (factories.length == 0) {
throw new PrinterException("No PostScript factories available");
}
PDDocument document = pdfGenerator.getDocument();
// Attributes are specified by https://docs.oracle.com/javase/7/docs/api/
// see package javax.print.attribute.standard
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
aset.add(MediaSizeName.NA_LETTER);
aset.add(new PageRanges(1, document.getNumberOfPages()));
FileOutputStream fos = new FileOutputStream(filePathAndName);
factories[0].getPrintService(fos).createPrintJob().print(
new SimpleDoc(new PDPageable(document), flavor, null), aset);
fos.close();
document.close();
PDPageable对象似乎不在PDFBox 2.0代码中,我没有在迁移文档中看到它。如何使用PDFBox 2.0将PDF文件转换为PostScript文件?
谢谢
答案 0 :(得分:0)
你是对的,在PDFBox version 1.18.12 Package org.apache.pdfbox.pdmodel有一个PDPageable类,但相应的version 2.0.3 Package org.apache.pdfbox.pdmodel没有。
但您想要做的是转换为PostScript语言文档。我认为PDFPrintable会为你做到这一点。
请参阅此另一个问题Printing to PostScript with PDFBox produces a massive file, why?,查看显示正在使用的PDFPrintable的代码段。我已将其简化了一下并将其包含在下面。你看起来很熟悉吗? : - )
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
aset.add(MediaSizeName.NA_LETTER);
FileOutputStream fos = new FileOutputStream(filePathAndName);
StreamPrintService sps = factories[0].getPrintService(fos);
DocPrintJob dpj = sps.createPrintJob();
SimpleDoc sd = new SimpleDoc(new PDFPrintable(document, Scaling.ACTUAL_SIZE, false), flavor, null);
factories[0].getPrintService(fos).createPrintJob().print(
new SimpleDoc(new PDFPrintable(document, Scaling.ACTUAL_SIZE, false), flavor, daset), aset);
fos.close();
document.close();
