For the following recipes you need to install HPDF.
1 Creating an empty PDF file
runPdf generates a PDF file in the file system.
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 let documentInfo = standardDocInfo runPdf outputFileName documentInfo 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
