Java runtime environment (JRE) is required to run this module.
const pdf2html = require('pdf2html');
const html = await pdf2html.html('sample.pdf');
console.log(html);const text = await pdf2html.text('sample.pdf');
console.log(text);const htmlPages = await pdf2html.pages('sample.pdf');
console.log(htmlPages);const options = { text: true };
const textPages = await pdf2html.pages('sample.pdf', options);
console.log(textPages);const meta = await pdf2html.meta('sample.pdf');
console.log(meta);The maxBuffer option specifies the largest number of bytes allowed on stdout or stderr. If this value is exceeded, then the child process is terminated.
By default, the maximum buffer size is 2MB. You can customize it by passing the maxBuffer option.
await pdf2html.meta('sample.pdf', { maxBuffer: 1024 * 10000 }); // set maxBuffer to 10MB
await pdf2html.html('sample.pdf', { maxBuffer: 1024 * 10000 });
await pdf2html.text('sample.pdf', { maxBuffer: 1024 * 10000 });
await pdf2html.pages('sample.pdf', { maxBuffer: 1024 * 10000 });
await pdf2html.thumbnail('sample.pdf', { maxBuffer: 1024 * 10000 });const thumbnailPath = await pdf2html.thumbnail('sample.pdf');
console.log(thumbnailPath);const options = { page: 1, imageType: 'png', width: 160, height: 226 };
const thumbnailPath = await pdf2html.thumbnail('sample.pdf', options);
