For the following recipes you need to install HPDF.

1 Creating an empty PDF file

runPdf writes a PDF file.

Let's create an empty PDF file with the name "test1.pdf": 

import Graphics.PDF
 
main :: IO ()
main = do
  let outputFileName= "test1.pdf"
  let defaultPageSize = PDFRect 0 0 200 300
 
  runPdf outputFileName standardDocInfo defaultPageSize $ do
    addPage Nothing

2 Pages with different sizes

If you pass "Nothing" to the function addPage, the default page size will be used for the size of the new page.

Let’s create three pages, the last two pages with different dimensions: 

import Graphics.PDF
 
main :: IO ()
main = do
  let outputFileName= "test2.pdf"
  let defaultPageSize = PDFRect 0 0 200 300
 
  runPdf outputFileName standardDocInfo defaultPageSize $ do
    addPage Nothing
    addPage $ Just $ PDFRect 0 0 100 100
    addPage $ Just $ PDFRect 0 0 150 150
