node node-xrlToXfdf.js --document=sample.xod --xrl=sample.xrl

For other document types, the width and height cannot be automatically retrieved. You must provide the width, height.

node node-xrlToXfdf.js --document=sample.pdf --xrl=sample.xrl --outXfdf=out-file.xfdf

Changing Text Annotation Size

node node-xrlToXfdf.js --document=sample.pdf --xrl=sample.xrl --scale=0.25

Changing Text Annotation Alignment

To manipulate the alignment of text in freetext annotations, the optional alignment parameter is used. Argument options = L, R, or C for Left, Right, or Center. Note: Center is used by default.

node node-xrlToXfdf.js --document=sample.pdf --xrl=sample.xrl --alignment=L

Running conversion in the browser

xrlToXfdf.min.js can be used directly used in the browser. It exposes a the function xrlToXfdf(inputXrlString, pageInfos) on the window.

inputXrlString is the contents of an .xrl markup file for annotations.

pageInfos is an array consisting of objects with the width, height and rotation of each page. Use the getPageInfo function on the document object to get the width and height. (https://www.pdftron.com/api/web/CoreControls.Document.html)

Use getPageRotation on the document object to get the page rotation in degrees.

The function will return a promise that resolves with the output xfdf string. Example:

window.xrlToXfdf('markup xrl content...', [{width: 595, height: 842, pageRotation: 0}, ...])
  .then(({ xfdf: xfdfString }) => {
    // do something here...
  });
