如果使用 gradle，可以使用以下方式包含最小依赖项：
implementation 'org.apache.xmlgraphics:batik-anim:1.13'
implementation 'org.apache.xmlgraphics:batik-awt-util:1.13'
implementation 'org.apache.xmlgraphics:batik-bridge:1.13'
implementation 'org.apache.xmlgraphics:batik-css:1.13'
implementation 'org.apache.xmlgraphics:batik-dom:1.13'
implementation 'org.apache.xmlgraphics:batik-ext:1.13'
implementation 'org.apache.xmlgraphics:batik-gvt:1.13'
implementation 'org.apache.xmlgraphics:batik-parser:1.13'
implementation 'org.apache.xmlgraphics:batik-script:1.13'
implementation 'org.apache.xmlgraphics:batik-svg-dom:1.13'
implementation 'org.apache.xmlgraphics:batik-svggen:1.13'
implementation 'org.apache.xmlgraphics:batik-transcoder:1.13'
implementation 'org.apache.xmlgraphics:batik-util:1.13'
implementation 'org.apache.xmlgraphics:batik-xml:1.13'
JasperReports 5.0 向服务器建议deploying reports 时基本相同的集合。不同之处在于 batik-transcoder（相对较新？）不在他们的列表中（尽管我认为 JasperReports 的更高版本需要它）：
batik-anim.jar
batik-awt-util.jar
batik-bridge.jar
batik-css.jar
batik-dom.jar
batik-ext.jar
batik-gvt.jar
batik-parser.jar
batik-script.jar
batik-svg-dom.jar
batik-svggen.jar
batik-util.jar
batik-xml.jar
获得一切：
implementation 'org.apache.xmlgraphics:batik-all:1.13'
根据需要更改版本号。
注意：我只针对两个 SVG 插图对此进行了测试。两者都完美呈现。根据您的要求，可能存在一些不需要的依赖项（例如 batik-anim）。
SVG Salamander 是另一个 SVG 引擎。比蜡染更轻，但没有那么坚固。请注意，Batik 无法轻松处理文本 flowRoot 元素，并可能导致黑框。消除黑匣子需要删除所有flowRoot 元素，这可能需要一些时间。 （另一种可能性是对 SVG 文件执行 XSL 转换以修复 flowRoot 问题，但这种方法可能无法解决遇到的所有问题。）
这是一个示例 SVGRasterizer 类，它构建并使用上述蜡染库文件的子集：
public class SVGRasterizer {

new SAXSVGDocumentFactory( getXMLParserClassName() );
