Explanation
- Initialization:
- Import ‘PDFDocument’ and ‘fs’.
- Create a new PDF document and set up a stream to save it.
- Content Addition:
- Add text, an image, and a new page with text and SVG path transformations.
- Annotations and Finalization:
- Add a page with blue text and a link to w3wiki.
- Finalize and close the PDF file.
- For adding new page in the PDF.
doc.addPage()
- For saving PDF document in root directory.
doc.pipe(fs.createWriteStream('PDF Name'));
Example: Below is the practical implementation of the create PDF document in Node.js.
// Filename - index.js
// Importing modules
import PDFDocument from 'pdfkit'
import fs from 'fs'
// Create a document
const doc = new PDFDocument();
// Saving the pdf file in root directory.
doc.pipe(fs.createWriteStream('example.pdf'));
// Adding functionality
doc
.fontSize(27)
.text('This the article for w3wiki', 100, 100);
// Adding an image in the pdf.
doc.image('download3.jpg', {
fit: [300, 300],
align: 'center',
valign: 'center'
});
doc
.addPage()
.fontSize(15)
.text('Generating PDF with the help of pdfkit', 100, 100);
// 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('The link for w3wiki website', 100, 100)
.link(100, 100, 160, 27, 'https://www.w3wiki.org/');
// Finalize PDF file
doc.end();
Output: Created PDF file will look like this.
