pdf - 在Grails中的PDF渲染插件中嵌入字体

Question

我想将“HelveticaNeueLTCom-BdCn.ttf”嵌入PDF文档中。我正在使用Grails渲染0.4.4插件来生成PDF文件。
我尝试跟随

@font-face {
   font-family: 'Helvetica';
   src: url('${grailsApplication.config.grails.serverURL}/fonts/HelveticaNeueLTCom-BdCn.ttf');
   -fs-pdf-font-embed: embed;
   -fs-pdf-font-encoding: Identity-H;
}

但这不起作用。

字体嵌入要求遵循以下步骤。这对我有用。
尝试告诉我您的反馈意见

插件内的PdfRenderingService类应为
对此字体模拟进行了如下编辑。

    protected doRender(Map args, Document document, OutputStream outputStream)           
    {
      def renderer = new ITextRenderer()

   // add the real font path from the server to be deployed to. 
   //I have it in the assets folder of my project
        def path=servletContext.getRealPath("/")+"assets/HelveticaNeueLTCom-BdCn.ttf"
    ITextFontResolver fontResolver=renderer.getFontResolver();

    //add the encoding and embedded types to the font
    fontResolver.addFont(path,BaseFont.IDENTITY_H, BaseFont.EMBEDDED);

    configureRenderer(renderer)
    renderer.setDocument(document, args.base)
    renderer.layout()
    renderer.createPDF(outputStream)
    outputStream.close();
}

在您的模板文件中添加以下代码

 @font-face {
    font-family: "Helvetica";
    src:    url("${grailsApplication.config.grails.serverURL}/assets/HelveticaNeueLTCom-BdCn.ttf") format("truetype"),
            url("${grailsApplication.config.grails.serverURL}/assets/HelveticaNeueLTCom-BdCn.woff") format("woff"),
            url("${grailsApplication.config.grails.serverURL}/assets/HelveticaNeueLTCom-BdCn.svg#HelveticaNeueLTCom-BdCn") format("svg");
    -fs-pdf-font-embed: embed;
    -fs-pdf-font-encoding: Identity-H;
}
