PdfCreator and PDFViewer wraps PDFBox

Did a bit of work myself and came with this.

b4j:
'draw multline
public Sub drawMultiText(acontent As JavaObject,afont As JavaObject,asize As Float,aleft As Float,atop As Float,aLine As Float,atext() As String) As Float
    For i = 0 To atext.Length-1
        Dim txt As String = atext(i)
        drawText(acontent,afont,asize,aleft,atop,txt)
        atop = atop - aLine
    Next
    Return atop
End Sub

Any example to open an existent pdf?
Hi, this library can't open existing PDF.

But the PDFBox which is used behind contains such methods. You have to look in that direction.
