Extend

• v1.0.9 and above break pagerender callback changelog
• If you need another format like json, you can change page render behaviour with a callback
• Check out https://mozilla.github.io/pdf.js/

// default render callback
function render_page(pageData) {
	//check documents https://mozilla.github.io/pdf.js/
	let render_options = {
		//replaces all occurrences of whitespace with standard spaces (0x20). The default value is `false`.
		normalizeWhitespace: false,
		//do not attempt to combine same line TextItem's. The default value is `false`.
		disableCombineTextItems: false
	};

	return pageData.getTextContent(render_options).then((textContent) => {
		let lastY,
			text = "";
		for (let item of textContent.items) {
			if (lastY == item.transform[5] || !lastY) {
				text += item.str;
			} else {
				text += "\n" + item.str;
			}
			lastY = item.transform[5];
		}
		return text;
	});
}

let options = {
	pagerender: render_page
};

const dataBuffer = fs.readFileSync("path/to/file.pdf");

PdfParse(dataBuffer, options).then((data) => {
	// use new format
});

Options

const DEFAULT_OPTIONS = {
	// internal page parser callback
	// you can set this option, if you need another format except raw text
	pagerender: render_page,

	// max page number to parse
	max: 0,
};

pagerender (callback)

If you need another format except raw text.

max (number)

Max number of page to parse. If the value is less than or equal to 0, parser renders all pages.
