layered pdf - possible ?

Hi all.

Some software products can create "layered" pdf, where you can switch on/off layers in pdf.
Can I create such pdf with jspdf?

for example, when I do context.drawImage(img), I would like this image to be one "layer" in PDF. Is this possible?

No, that isn't possible.
