pdfbuddy [dot] com is an online solution to upload your pdf files, edit (draw, highlight etc etc) and later save/download the modified files.
I am curious to know what could probably be the server-side solution they use?
When I draw something random and save the changes, the ajax request posted is, like:
document[data]:{"pages":{"1":{"elements":[{"type":"PATH","family":"PATH","style":{"stroke_width":2,"stroke_color":"#000000"},"transform":{"x":"247.5","y":"173","scaleX":"1","scaleY":"1"},"content":{"data":"M64

What exactly is those values in content->data? Which application on their server process this data and generate new pdf files?
Thank you!
