PDFKit 介绍

PDFKit 是一个用于Node和浏览器的PDF文档生成库，可以轻松创建复杂的多页面可打印文档。 API包含可链接性，包括低级功能以及更高级功能的抽象。
PDFKit API设计简单，因此生成复杂文档通常与一些函数调用一样简单。

主要特性：

• Vector graphics
  • HTML5 canvas-like API
  • Path operations
  • SVG path parser for easy path creation
  • Transformations
  • Linear and radial gradients
• Text
  • Line wrapping
  • Text alignments
  • Bulleted lists
• Font embedding
  • Supports TrueType (.ttf), OpenType (.otf), WOFF, WOFF2, TrueType Collections (.ttc), and Datafork TrueType (.dfont) fonts
  • Font subsetting
  • See fontkit for more details on advanced glyph layout support.
• Image embedding
  • Supports JPEG and PNG files (including indexed PNGs, and PNGs with transparency)
• Annotations
  • Links
  • Notes
  • Highlights
  • Underlines
  • etc.
• Outlines
• PDF security
  • Encryption
  • Access privileges (printing, copying, modifying, annotating, form filling, content accessibility, document assembly)

安装：npm install pdfkit

示例代码：

const PDFDocument = require('pdfkit');

// Create a document
const doc = new PDFDocument;

// Pipe its output somewhere, like to a file or HTTP response
// See below for browser usage
doc.pipe(fs.createWriteStream('output.pdf'));

// Embed a font, set the font size, and render some text
doc.font('fonts/PalatinoBold.ttf')
   .fontSize(25)
   .text('Some text with an embedded font!', 100, 100);

// Add an image, constrain it to a given size, and center it vertically and horizontally
doc.image('path/to/image.png', {
   fit: [250, 300],
   align: 'center',
   valign: 'center'
});

// Add another page
doc.addPage()
   .fontSize(25)
   .text('Here is some vector graphics...', 100, 100);

// Draw a triangle
doc.save()
   .moveto(100, 150)
   .lineto(100, 250)
   .lineto(200, 250)
   .fill("#FF3300");

// Apply some transforms and render an SVG path with the 'even-odd' fill rule
doc.scale(0.6)
   .translate(470, -380)
   .path('M 250,75 L 323,301 131,161 369,161 177,301 z')
   .fill('red', 'even-odd')
   .restore();

// Add some text with annotations
doc.addPage()
   .fillColor("blue")
   .text('Here is a link!', 100, 100)
   .underline(100, 100, 160, 27, {color: "#0000FF"})
   .link(100, 100, 160, 27, 'http://google.com/');

// Finalize PDF file
doc.end();
