How to put current date time on PDF document?

[Harshal_Shravgi]

We are on OnBase 17 SP1. I want to write a Unity script to be executed from workflow. This script should put below text at top-right corner of the PDF document imported in OnBase.

Text:

FILED

Current Date-Time

I have a custom C#.net program where I could do this using iText 7 library.

Can somebody give me an idea on how to do it in OnBase Unity API script?

I tried using RedactionImageModification but it is not working with PDFs.

Hello Harshall,

If you have Document Import Procesor, you can check in Options/Run Process/Add to Workflow On Commit, then configure in your document / Life Cycles a litle Queue that will execute a Unity Script that you will create as IWorkFlowScript that will (1) Download current document (2) execute your iTextSharp Code to apply your FILED text with Commit datetime (3) update revision . No need to convert to image or someting like that. I forgot to ask if you are a API Certified? so you can access to sdk.onbase.com and read documentation. Feel free to ask if you need more information.

Best wishes from Perú

Hi, Thanks for your response. Yes, i am API certified and could access SDK. Could you guide me to an example of updating revision of existing document in SDK? My plan of action:

1. On commit, document enters the workflow

2. Export the document (save out document) to a temporary location

3. Use iText7 library (I ) to at datetime and create a new PDF at temporary location

4. Import this new edited PDF as new revision and may be remove old revision

I need help on point 4. How to do it?

Hello Harshal,

Document Parameter is args.Document and fileBarcodePath is the new pdf, fileFormatPDFTemplate = 16

private void CreateRevision(Hyland.Unity.Application app, Hyland.Unity.Document document, string fileBarcodePath) {
FileType fileType = app.Core.FileTypes.Find(long.Parse(fileFormatPDFTemplate));
StoreRevisionProperties props = app.Core.Storage.CreateStoreRevisionProperties(document, fileType);
List<string> fileList = new List<string>();
fileList.Add(fileBarcodePath);
Hyland.Unity.Document renditionDocument = app.Core.Storage.StoreNewRevision(fileList, props);
}

Thanks, Everything is working as expected but my document now have 2 revisions - one original and the new one with date time stamped. I wrote below below code:

Storage storage = app.Core.Storage;
StoreRevisionProperties storeRevisionProperties = storage.CreateStoreRevisionProperties(args.Document, pdfFileType);
storeRevisionProperties.Comment = "FILED";
List<string> fileList = new List<string>();
fileList.Add(destPath);
Hyland.Unity.Document newDocument = storage.StoreNewRevision(fileList, storeRevisionProperties);

After adding this new revision, I want to delete original revision. I don't want my users to see previous revision.  Basically, I want to update the revision and not to add new revision.

I have below document configuration settings -

Ok, then you will need to delete your first document and upload a new one but both of them will not be the same document, this new document won't be the "commited" version strickly speaking 😉
