java 生成pdf文件嵌入字体_java - OpenHTMLToPDF：将自定义字体嵌入到由HTML创建的PDF中 - 堆栈内存溢出...

我使用Jsoup和OpenHTMLToPDF从HTML创建PDF。 我必须在PDF中使用其他字体来覆盖非拉丁字形(请参见此处 )。 如何正确嵌入我的字体？

简化程序再现了该问题：

SRC /主/资源/ test.html中

Font Test

@font-face {

font-family: 'source-sans';

font-style: normal;

font-weight: 400;

src: url(fonts/SourceSansPro-Regular.ttf);

}

Latin Script

Είμαι ελληνικό κείμενο.

该文件应以PDF格式编写

在浏览器中，它看起来正确，并使用Source Sans字体。

的src / main / JAVA / main.java：

import com.openhtmltopdf.extend.FSSupplier;

import com.openhtmltopdf.pdfboxout.PdfRendererBuilder;

import org.jsoup.Jsoup;

import org.jsoup.helper.W3CDom;

import org.w3c.dom.Document;

import java.io.*;

import java.nio.charset.StandardCharsets;

import java.util.Objects;

public class main {

public static void main(String[] args) {

System.out.println("Starting");

try {

final W3CDom w3cDom = new W3CDom();

final Document w3cDoc = w3cDom.fromJsoup(Jsoup.parse(readFile()));

final OutputStream outStream = new FileOutputStream("test.pdf");

final PdfRendererBuilder pdfBuilder = new PdfRendererBuilder();

pdfBuilder.useFastMode();

pdfBuilder.withW3cDocument(w3cDoc, "/");

pdfBuilder.useFont(new File(main.class.getClassLoader().getResource("fonts/SourceSansPro-Regular.ttf").getFile()), "source-sans");

pdfBuilder.toStream(outStream);

pdfBuilder.run();

outStream.close();

} catch (Exception e) {

System.out.println("PDF could not be created: " + e.getMessage());

}

System.out.println("Finish.");

}

private static String readFile() throws IOException {

final ClassLoader classLoader = main.class.getClassLoader();

final InputStream inputStream = classLoader.getResourceAsStream("test.html");

final StringBuilder sb = new StringBuilder();

final Reader r = new InputStreamReader(Objects.requireNonNull(inputStream), StandardCharsets.UTF_8);

char[] buf = new char[1024];

int amt = r.read(buf);

while(amt > 0) {

sb.append(buf, 0, amt);

amt = r.read(buf);

}

return sb.toString();

}

}

不用担心第二个功能，它只读取HTML文件，并且仅包含在此处，以具有完整的程序。

在衬线字体。

编辑1：根据注释中链接的页面进行各种更改，并更新为RC18。 现在新的输出，但是PDF中的字体仍然不正确。

编辑2：尝试快速渲染器
