For the following recipes you need to install HPDF.
Creating an empty PDF file
runPdf generates a PDF file in the file system. You need to pass it four things:
- a file name for the PDF file
- document information
- a default page size
- a PDF Action
Let's create an empty PDF file with the name "test1.pdf":
import Graphics.PDF
main :: IO ()
main = do
let outputFileName= "test1.pdf"
let documentInfo = standardDocInfo
let defaultPageSize = PDFRect 0 0 200 300
runPdf outputFileName documentInfo 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 documentInfo = standardDocInfo
let defaultPageSize = PDFRect 0 0 200 300
runPdf outputFileName documentInfo defaultPageSize $ do
addPage Nothing
addPage $ Just $ PDFRect 0 0 100 100
addPage $ Just $ PDFRect 0 0 150 150
