IPDFSplitMerge ( PDFSplitMergeLib.PDFSplitMerge object) interface methods

Methods of IPDFSplitMerge interface ( PDFSplitMergeLib.PDFSplitMerge object)	Description
AddPDFFromFileName(PDFFileName as String) as Integer	Add PDF document to the internal list of files to process. Returns index of PDF document in internal list. This index is intended to use with other methods like GetPagesCount, SplitPagesToFolder etc.
GetPagesCount(PDFIndex as Integer) as Integer	Returns number of pages in PDF document referenced by PDF document index in internal list of PDF documents. Add PDF document into list using .AddPDFFromFileName method
SplitPagesToFolder(Path as String, BaseFileName as String, PDFIndex as Integer, Pages as String) as Boolean	Extracts pages from PDF document referenced by PDFIndex (index of PDF document in internal list) into given folder and creates PDF document for every single extracted page. Path - path to folder to store PDF documents with extracted pages BaseFileName - base filename for generated PDF documents PDFIndex - index of PDF document in internal collection of documents (add to collectionusing .AddPDFFromFileName method) Pages - string containing comma-separated page numbers of pages to extract. Use "-" to define range of pages, for example: "1,3-5,7" will extract 1,3,4,5,7 pages Generated filenames for pages are generated using the rule: Path/BaseFileName - XXXXX.pdf where XXXXX is the page number Method returns True if extraction was successfull or False otherwise. Also check SelectPagesToExtract and SaveToFile method for extracting pages and saving them into single PDF document
MergeToFile(FileName as String, FileList as String) as Boolean	Method merges selected PDF documents previously added into internal collection using .AddPDFFromFileName method into single PDF document. Filename - filename of single PDF document containing merged PDF documents FileList - string containg comma-separated indexes of PDF documents to merge. For example: "1,3-6" will merge PDF document number 1,3,4,5,6 into single final PDF document. Index of PDF document is returned by .AddPDFFromFileName method.
SelectPagesToExtract (PDFIndex as Integer, Pages as String) as Boolean	Selects pages from PDF document for further extraction and merging into single PDF document. This can be used for purpose of extracting given pages from 2 or more documents to merger them into 1 single PDF document. PDFIndex - index of PDF document to select pages in. Index of PDF document is returned by .AddPDFFromFileName method Pages - comma-separated numbers of pages to extract from PDF document. For example: "1,3-5" will select pages #1,3,4,5 for further extraction and saving into PDF document using .SaveToFile method
SaveToFile (FileName as String) as Boolean	Merges selected pages (see .SelectPagesToExtract method) and saves into PDF document (FileName parameter)

Sample Code - How To Use

(1) SelectPagesFromDocumentAndSaveToFile.vbs - sample demonstrating how to extract selected pages from PDF document (sample1.pdf) and then merge and save them into new PDF document file. You can find this sample and sample PDF documents in /examples/ sub-folder.

Dim PdfSpliter

Set PdfSpliter = CreateObject("PDFSplitMergeLib.PDFSplitMerge")

' adding PDF document and get its index in internal collection
Sample1Index = PdfSpliter.AddPDFFromFileName ( "Sample1.pdf" )

' selecting pages 1,3,4,5 to extract
PdfSpliter.SelectPagesToExtract Sample1Index,"1,3-5"

' now save extracted pages into single PDF document
PdfSpliter.SaveToFile("SelectPagesFromDocumentAndSaveToFile.pdf")

(2) SelectPagesFromTwoDocumentAndSaveIntoSingleFile.vbs - sample demonstrating how to extract selected pages from two different PDF document (sample1.pdf and sample2.pdf) and then merge extracted pages into new single PDF document file. You can find this sample and sample PDF documents in /examples/ sub-folder.

Dim PdfSpliter

Set PdfSpliter = CreateObject("PDFSplitMergeLib.PDFSplitMerge")

' extracting pages from Sample1.pdf
Sample1Index = PdfSpliter.AddPDFFromFileName ("Sample1.pdf")
' select pages 1,3,4,5 from sample.pdf
PdfSpliter.SelectPagesToExtract Sample1Index,"1,3-5"

' extracting pages from Sample2.pdf
Sample2Index = PdfSpliter.AddPDFFromFileName ("Sample2.pdf")
' select pages 2,3,4 from sample2.pdf
PdfSpliter.SelectPagesToExtract Sample2Index,"2-4"

' saving extracted pages into sinlge PDF document
PdfSpliter.SaveToFile("SelectPagesFromTwoDocumentAndSaveIntoSingleFile.pdf")
