java - iText7 将 SVG 添加到 PdfDocument 中以及可能出现的问题

Question

关于问题的答案:如何使用 iText7 将 SVG 添加到 PDF

这是一个链接click here!

当我使用示例java代码时，出现错误。

错误: com.itextpdf.styledxmlparser.node.impl.jsoup.JsoupXmlParser - 无法映射节点类型:类 com.itextpdf.styledxmlparser.jsoup.nodes.XmlDeclaration

导致该错误的原因可能是什么？如何避免？

依赖关系:

dependencies {
  compile 'com.itextpdf:kernel:7.1.2'
  compile 'com.itextpdf:io:7.1.2'
  compile 'com.itextpdf:layout:7.1.2'
  compile 'com.itextpdf:forms:7.1.2'
  compile 'com.itextpdf:pdfa:7.1.2'
  compile 'com.itextpdf:pdftest:7.1.2'
  compile 'com.itextpdf:svg:7.1.2'
  //-- pdfHTML --
  compile 'com.itextpdf:html2pdf:1.0.0'
  //-- Kerning --
  compile 'com.itextpdf:typography:1.0.0'
  //-- iText 7 License Key Library --
  compile 'com.itextpdf:itext-licensekey:2.0.3'
}

示例java代码:

PdfDocument doc = new PdfDocument(
new PdfWriter(new FileOutputStream(new File(".../test.pdf")),new WriterProperties().setCompressionLevel(0)));
doc.addNewPage();

URL svgUrl = null;
svgPath = ".../test.svg";

try{
    svgUrl = new URL(svgPath);
}
catch(MalformedURLException mue){...}

if(svgUrl == null){
    try{
        svgUrl = new File(svgPath).toURI().toURL();
    }
    catch(Throwable th){...}
}

SvgConverter.drawOnDocument(svgUrl.openStream(), doc, 1);
doc.close();

SVG 代码:

Answer 1

这是一个错误，似乎已在最新的开发版本中修复。虽然我们今天发布了，但发布版本是基于两周前交付的版本。我在最新的快照版本(7.1.3-SNAPSHOT)上尝试了你的 svg，它输出正确。

您可以在 GitHub 上找到最新版本:https://github.com/itext/i7j-svg但你必须从源头开始构建。如果您不想这样做，您可以将我们的工件添加到 pom 文件中的存储库元素中，并提取最新的快照。

<repository>
    <id>snapshots</id>
    <name>iText Repository-snapshots</name>
    <url>https://repo.itextsupport.com/snapshot</url>
</repository>

具有以下工件:

<dependency>
    <groupId>com.itextpdf</groupId>
    <artifactId>svg</artifactId>
    <version>7.1.3-SNAPSHOT</version>
</dependency>
