Oh, The architecture is made by a WCF feeded with a PDF that's the module on which we must recognize signatures presence.

Sorry for the english.

You can try our OCR – ICR Module which is an add-on to LEADTOOLS Document Imaging.
You will also need PDF Read SDK.

Please see the following pages in our website:

I recommend you try the free Eval edition of LEADTOOLS:

thank you for the support.

I think what i need is much more simple, btw.
What i want to do is not read the signature, but only detect if there's one in the specific spot . Something like grey or black percentage in the area.

I'm sorry, I've no experience at all in the OCR field and i feel a little lost in the LT SDK that has a lot of features.
I found CSOcrWorkflowDemo_x86.csproj DEMO that i feel is mi good starting point.

You can use BlankPageDetectorCommand Class which is available in the Document\Medical Toolkits.
It basically detects whether an image is a blank page or not.

You can create a new image from the region over the signature area and apply BlankPageDetectorCommand on the new image.

For more info, please see the following help topic:
