TextStamp Feature

We are using the TextStamp feature in aspose to stamp text on average size docs (~200 pages) and sometimes we get these strange errors


Item has already been added. Key in dictionary: ‘space’ Key being added: 'space’

or other random key in dictionary phrases


Can you please explain why ? What is is trying to do, keep track of all the stamps on the pages and runs out of keys to give each stamp?



Hi William,

We will appreciate if you please share a problematic PDF document and sample code. Moreover, please confirm the API version that you are using. We will try to replicate the issue and will provide information accordingly.

Best Regards,

I see this is in another thread I would like this one closed
