嵌入自定义字体

此示例显示如何将自定义字体嵌入到文档中。

除了使用标准字体外,PdfDocument还提供了将自定义字体嵌入到文档中的功能。 支持以下字体格式:.ttf,.ttc,.dfont。

在此示例中,使用了Fira字体系列,两种字体 FiraSans-Regular.ttfFiraSans-Bold.ttf, 嵌入到文档中。

首先,必须使用 registerFont (或 registerFontAsync)方法注册自定义字体。 此方法从URL加载字体并将其与指定的字体系列名称和字体属性(如样式,权重,无论是serif还是sans serif字体等)相关联。 之后,字体系列名称可以与PdfFont类一起使用,就像任何其他标准字体一样。

例如:

doc.registerFont({
    source: "resources/fonts/fira/FiraSans-Regular.ttf",
    name: "fira",
    style: "normal",
    weight: "normal",
    sansSerif: true
});

doc.drawText("Here is the FiraSans-Regular font.", null, null, {
    // an equivalent of font: new wijmo.pdf.PdfFont("fira", 10, "normal", "normal")
    font: new wijmo.pdf.PdfFont("fira")
});
import 'bootstrap.css'; import './styles.css'; import * as pdf from '@grapecity/wijmo.pdf'; // document.readyState === 'complete' ? init() : window.onload = init; // function init() { document.querySelector('#btnExport').addEventListener('click', () => { let doc = new pdf.PdfDocument({ ended: (sender, args) => pdf.saveBlob(args.blob, 'Document.pdf') }); // doc.registerFont({ source: 'resources/fira/FiraSans-Regular.ttf', name: 'fira', style: 'normal', weight: 'normal', sansSerif: true }); // doc.registerFont({ source: 'resources/fira/FiraSans-Bold.ttf', name: 'fira', style: 'normal', weight: 'bold', sansSerif: true }); // doc.drawText('Here is the standard Times font.'); // let font = new pdf.PdfFont('fira'); doc.drawText('Here is the FiraSans-Regular font.', null, null, { font: font }); // font.weight = 'bold'; doc.drawText('Here is the FiraSans-Bold font.', null, null, { font: font });
