PDFBox—将页面保存为SVG格式

Question

我试图将给定PDF文档的每个页面保存为SVG文件。与非常流行的SVG到PDF相比，关于该主题的信息似乎很少。

是否有一个简单的方法来做到这一点使用PDFBox，蜡染或标准库功能的任何组合?

Answer 1

这是一些保存PDF所有页面的代码，我可能从这里或从蜡染本身。

try (PDDocument pdfboxDocument = PDDocument.load(new File(dir, PDFFILE)))
{
PDFRenderer r = new PDFRenderer(pdfboxDocument);
for (int i = 0; i < pdfboxDocument.getNumberOfPages(); ++i)
{
String svgNS = "http://www.w3.org/2000/svg";
DOMImplementation impl = GenericDOMImplementation.getDOMImplementation();
Document myFactory = impl.createDocument(svgNS, "svg", null);
SVGGeneratorContext ctx = SVGGeneratorContext.createDefault(myFactory);
ctx.setEmbeddedFontsOn(true);
SVGGraphics2D g2d = new SVGGraphics2D(ctx, true);
r.renderPageToGraphics(i, g2d);
String filename = "test-" + (i + 1) + ".svg";
try (Writer out = new OutputStreamWriter(new FileOutputStream(new File(dir, filename)), "UTF-8"))
{
g2d.stream(out, true);
}
}
}
