RasterEdge .NET Image SDK has included a variety of image and document processing library components, one of which is the PDF document editing control DLL. This library DLL can efficiently enable developers to merge two or more PDF document into one and then save as another PDF document using Visual Basic .NET programming codes.
Different from PDF document appending, which is processed by directly tagging the second PDF file to the target one, this PDF file merge function will put the two target PDF together and save as new PDF, without changing the previous two PDF documents at all.
