i found this post extract pages pdf file using itextsharp lib. document have different orientation each page , pagesize ist different to. first of try fix page orientation. here code , im out of ideas perhaps can tell me how this.
public function extractpdfpages(byval sourcefile string, byval targetfile string, byval intstr integer, byval intend integer) try dim imppage pdfimportedpage = nothing dim reader new pdfreader(sourcefile) dim pagerotation string = "" dim srcdoc new document(reader.getpagesizewithrotation(intstr)) dim pdfcopyprovider new pdfcopy(srcdoc, new system.io.filestream(targetpath & "\" & targetfile, system.io.filemode.create)) srcdoc.open() x = intstr intend imppage = pdfcopyprovider.getimportedpage(reader, x) dim mydocor rectangle = reader.getpagesize(x) if mydocor.width >= mydocor.height pagerotation = "land" else pagerotation = "port" end if ' --- fix orientation ' --- add page pdfcopyprovider.addpage(imppage) next srcdoc.close() reader.close() catch ex exception throw ex end try end function
this me. else how have same issue here solution :
public function extractpdfpages(byval sourcefile string, byval targetfile string, byval intstr integer, byval intend integer) try dim imppage pdfimportedpage = nothing dim reader new pdfreader(sourcefile) dim pagerotation string = "" dim srcdoc new document(reader.getpagesizewithrotation(intstr)) dim pdfcopyprovider new pdfcopy(srcdoc, new system.io.filestream(targetpath & "\" & targetfile, system.io.filemode.create)) srcdoc.open() x = intstr intend imppage = pdfcopyprovider.getimportedpage(reader, x) pdfcopyprovider.setpagesize(new rectangle(0.0f, 0.0f, imppage.width, imppage.height)) pdfcopyprovider.addpage(imppage) next srcdoc.close() reader.close() catch ex exception throw ex end try end function the magic set pagesize.
pdfcopyprovider.setpagesize(new rectangle(0.0f, 0.0f, imppage.width, imppage.height))
