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/

`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

`js
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,
};
``

$3

If you need another format except raw text.

$3

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