It offers functionalities to manipulate and transform images before converting them to a PDF format. This package is a powerful tool for developers looking to generate PDF files from images in their JavaScript applications.

To start using the images-pdf
package, you first need to install it in your project. Open the terminal or command prompt and run the following command:
npm install images-pdf
Once installed, you can import the library into your JavaScript file using the require
or import
statement, depending on your project setup. Here's an example:
const imagesToPdf = require('images-pdf');
Let's see a simple code snippet that demonstrates how to convert multiple images to a PDF document using images-pdf
:
const imagesToPdf = require('images-pdf');
const images = [
'path/to/image1.jpg',
'path/to/image2.png',
'path/to/image3.gif'
];
const options = {
quality: 0.8,
pageSize: 'A4',
margin: {
top: '10mm',
right: '15mm',
bottom: '10mm',
left: '15mm'
},
header: {
text: 'My Converted Images PDF',
alignment: 'center',
fontSize: 16,
fontColor: '#333333'
}
};
imagesToPdf.convert(images, 'path/to/output.pdf', options)
.then(() => {
console.log('Images successfully converted to PDF!');
})
.catch((error) => {
console.error('Error converting images to PDF:', error);
});
In the above example, we have an array of image paths images
and an options
object with various customization settings. The convert
method is then called with the images, desired output file path, and options. The promise-based syntax is used to handle the success and error scenarios.
Please note that the above example is a basic illustration of the library's usage. You can explore the documentation and the available options to adapt it as per your requirements.
