在 Grails 的 PDF 渲染插件中嵌入字体

Question

I want to embed 'HelveticaNeueLTCom-BdCn.ttf' in a PDF document. I'm using Grails rendering 0.4.4 Plugin to generate PDF file. I tried following,

@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;
}

but it doesn't work.

Answer 1

The font embedding requires the below steps to be followed. This worked for me. Try and tell me your feedback

1. The PdfRenderingService class present inside the plugin should be edited for this font simulation as below.

    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(); }

2. Add the below code in your template file

    @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; }

Answer 2

@font-face { src:url(${grailsApplication.config.app.serverUrl}/arialuni.ttf) ; -fs-pdf-font-embed: embed; -fs-pdf-font-encoding: Identity-H; }

这对我有用。

Answer 3

Probably the problem is that you have your url value surrounded by ' instead of " .

The difference between them is that, though in Groovy string literals can be made with both, only the ones surrounded by " create GString, which evaluates statements between ${}

Answer 4

This worked for me

@font-face {
    src: url("path/to/KF-Kiran.ttf");
    -fs-pdf-font-embed: embed;
    -fs-pdf-font-encoding: cp1250;
}

div {
    font-family: 'KF-Kiran';  // here give the same name of .ttf file.
}
