为 FOP 从 JAR 加载字体

问题描述

我的应用程序在 JAR 的 fonts 目录中有一个 TTF 字体.

I have a TTF font in fonts directory in the JAR with my application.

 myapp.jar /
     fop /
        config.xml
        font.ttf

我以这种方式创建我的 FOP:

I create my FOP this way:

    FopFactory fopFactory = FopFactory.newInstance();
    fopFactory.setStrictValidation(false);
    fopFactory.setUserConfig(getClasspathFile("/fop/config.xml"));
    FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
   ...

如何配置 config.xml 以在我渲染的 PDF 文件中嵌入 font.ttf?

How do I configure config.xml to embeddd font.ttf in the PDF file I am rendering?

看来我的帖子来得太晚了，但可能对其他人有用.[java 8，fop 2.1]

it seems that my post is too late, but may be it'll be useful for the others.[java 8, fop 2.1]

import lombok.SneakyThrows;
...
        @SneakyThrows
            private FopFactory getFopFactory(){
                InputStream fopConfigStream = Thread.currentThread().getContextClassLoader().getResourceAsStream("/fop/config.xml");
                FopFactoryBuilder builder = new FopFactoryBuilder(new File(".").toURI(), new CustomPathResolver());
                FopFactory factory = builder.setConfiguration(new DefaultConfigurationBuilder().build(fopConfigStream)).build();
                fopConfigStream.close();
                return factory;
            }
    ...
        private static final class CustomPathResolver implements ResourceResolver {
            @Override
            public OutputStream getOutputStream(URI uri) throws IOException {
                return Thread.currentThread().getContextClassLoader().getResource(uri.toString()).openConnection()
                        .getOutputStream();
            }

            @Override
            public Resource getResource(URI uri) throws IOException {
                InputStream inputStream = ClassLoader.getSystemResourceAsStream("fop/" + FilenameUtils.getName(uri));
                return new Resource(inputStream);
            }
        }

config.xml:

config.xml:

<fop version="1.0">
    <renderers>
        <renderer mime="application/pdf">
            <fonts>
              <font kerning="yes" embed-url="font.ttf" embedding-mode="subset">
                <font-triplet name="Font name" style="normal" weight="normal"/>
              </font>
            </fonts>
        </renderer>
    </renderers>
</fop>
