I am working currently on a project and i haven't found a solution how to realize it yet. I am not asking for the solution. I would be very thankful if someone could give me some hints or tell me in which direction i could go to reach my goal.
Currently i am thinking about trying to solve it by programming an web-application. But i am not sure if a windows forms application would even be better. I am also open for other solutions.
My goal is following:
I have some (real world) documents which are being scanned and afterwards scanned with an OCR-Scanner, which generates some PDF-Documents. Next i want to open one of these generated PDF-Files in a User Interface which shows me the PDF. The user should be able to select some (one after another) text-blocks, which are downloaded from a database, and drag them over the pdf and drop it at some position.
Now i want to save or print the pdf with the text-blocks, just as the user sees it. Kind of making a screenshot of the pdf but resulting in a pdf file with the same dimensions as before. Currently i have no idea how to "merge" these two.
Which technologies should i use. What would you recommend me. Would a web-application or something native be better suitable for that purpose.
I have written some kind of mockup to show what i mean. Please put some pdf named "testpdf.pdf" to the same folder if you want to test it. It works on Chrome ... not sure about the others.
Thanks a lot
