How to Rotate PDF by Degrees in VBScript (Visual Basic 6)

The code sample below will demonstrate how to rotate PDF by degrees in VBScript (Visual Basic 6).

' Create Bytescout.PDFExtractor.DocumentRotator object
Set rotator = CreateObject("Bytescout.PDFExtractor.DocumentRotator")
rotator.RegistrationName = "demo"
rotator.RegistrationKey = "demo"

rotator.Rotate "..\..\sample1.pdf", "result.pdf", 0 ' 0 - rotate 90 deg, 1 - rotate 180 deg, 2 - rotate 270 deg
                
Set rotator = Nothing
