Set the height of a PDF page retroactively
Raw
height.js
doc.addPage();
// add content
// this sets the height in the actual PDF output
// MediaBox[1] is really the Y, but PDFs use a flipped coordinate system
// where y=0 is at the bottom.
// make sure you do this before adding another page
doc.page.dictionary.data.MediaBox[1] = doc.page.height - doc.y;
// set the height (just used for layout, you might be able to get
// away without setting it if not adding anything more to the page)
doc.page.height = doc.y;
