Hello,
In a PDF document. I would like to know if it is possible to copy a selected text area in the document.
Color this selection and repaste it at the same place.
I do manage to copy text and then paste it after I colored the zone of the text but the text format is not exactly the same than in the original document.
Can you please help ?
Thanks.

Hi Nicolas,
Thanks for your inquiry. You can get font name along with other text properties and use while updating the text. Moreover, if you are looking for the workaround to highlight text in scanned PDf documents then please use Highlight Annotation as suggested in your other post, it will resolve the issue.
Please feel free to contact us for any further assistance.
Best Regards,
