In http://blog.aloaha.com/2012/09/13/split-large-pdf-into-multiple-small-pdfs/ we explain how to use the Aloaha API to split large PDF documents into many small documents. In case someone is not able to write or use any scripting language it is possible to use the Aloaha Scripting Engine. Below you find the same sample code implemented as Aloaha Workflow Definition File:

‘define variable for output path
Type=set
ValueName=OutPutPath
Value=c:\pdf\out\
Nextblock=dirblock

[dirblock]
‘enumerate files in input path
Type=dir
Extension=pdf
Directory=%OrgPath%
ResultName=files
Nextblock=CheckLoaded

[CheckLoaded]
‘if enumerated files empty then end – else call com function
Type=condition
Input1=%files%
Input2=”"
TrueBlock=end
FalseBlock=CallCOMFunction

[CallCOMFunction]
Type=com
Object=aloahapdf.edit
Function=SplitAndSave
Parameter=5
Parameter0=%OrgPath%
Parameter1=%OutPutPath%
Parameter2=”Der Rechnungsbetrag wird von Ihrem Konto”
Parameter3=”"
Parameter4=Kunden-Nr.:
ResultName=CallCOMFunctionResult
Nextblock=foreachblock

[foreachblock]
‘loop through original files and delete them
Type=foreach
Nextblock=deletefile
LoopName=DeleteLoop
LoopCSV=%files%
ResultName=LoopTemp

[deletefile]
Type=delfile
DeleteFile=%LoopTemp%
Nextblock=endeachblock

[endeachblock]
Type=endeach
LoopName=DeleteLoop
Nextblock=end

Some accounting applications are only able to generate one large PDF containing all invoices. If the use needs the invoices as single files there needs to be a mechanism to split them. With the Aloaha SplitAndSave API this is no problem at all.

1. Since every invoice can have a different number of pages any text can be defined as page seperator marking. For example “Kind Regards”
2. A regular expression can be used to extract a string from the PDF to be used as filename. For example “Customer-Number:”

Here a small example on how to use the API:

Dim InputFolder
Dim OutPutFolder
Dim SplitterString
Dim pdf
Dim Letterhead
Dim FileNameRegEx
InputFolder = “c:\pdf”
OutPutFolder = “c:\pdf\out”
SplitterString = “Der Rechnungsbetrag wird von Ihrem Konto”
FileNameRegEx = “Kunden-Nr.:”

set pdf = createobject(“aloahapdf.edit”)
Call pdf.SplitAndSave(cstr(InputFolder), cstr(OutPutFolder), cstr(SplitterString), cstr(Letterhead), cstr(FileNameRegEx))
Set pdf = Nothing

In case it is not possible to use a scripting language such as VBS it is possible to use the inbuilt Aloaha Workflow Engine. A sample definition file can be found here:

Should you have the requirement just to split one file and not X Files in a folder please use the script below. Please note that you need an Enterprise Key. An Evaluation key can be requested at info(at)aloaha.com

On Error Resume Next

Dim InputFolder
Dim OutPutFolder
Dim SplitterString
Dim pdf
Dim Letterhead
Dim FileNameRegEx
Dim Pages
Dim SeiteVon
Dim SeiteBis

InputFolder = “c:\pdf\Testkopien.pdf”

OutPutFolder = “c:\pdf\out”

SplitterString = “Rechnungsbetrag Euro”

FileNameRegEx = “([^Kunden-](Nr.:(.[0-9]*)))”

SeiteVon = 10
SeiteBis = 20
set pdf = createobject(“aloahapdf.edit”)
Pages = pdf.PDFDocumentPages( InputFolder)
Wscript.Echo (“seiten ” & Pages)
Call pdf.SplitPDFFile(cstr(InputFolder), cstr(OutPutFolder), cstr(SplitterString), cstr(SeiteVon), cstr(SeiteBis), cstr(FileNameRegEx))

Set pdf = Nothing

User with the Enterprise License can use the Aloaha Scripting APIs as explained on:
http://www.aloaha.com/software-development/pdf-sdk.php

To splitt all multipage PDFs of a given path requires only 3 lines of code:
(http://www.aloaha.com/software-development/freeware-apis.php)

Set pdf = CreateObject(“aloahapdf.edit”)

                              Call pdf.split_pdf_in_dir(CStr(“c:\tosplit”))

Set pdf = nothing
