Creating an empty PDF file
The following code creates 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
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
