Clearly, you didn’t understand anything I said or suggested. I shouldn’t even bother.
Please read it again and try to actually understand it. Your document wasn’t created or saved in the same manner or the same number of times. So it wouldn’t have the same aspects.
Okay, I’ll try to explain the straight cut lines ...
If I have one document with text printed on an image (e.g. purple security paper with little pink roses) and I need to extract (cut, whatever) ONLY the black lines and text from a scanned image of that physical document, how do I do that without getting parts of the purple and pink?
Now I want to paste that extracted text (and lines) into a blank PDF document. Then I’m gonna print that new PDF document on retina-burn, lime green security paper.
Then, I’m gonna scan that newly printed sheet of physical paper and insert it into a blank PDF.
Then I’ll post it on the Internet.
So my question for you is: How do I get just the black lines and text from the first document onto the second document without also creating those white halo thingamuhjiggers and without snagging pieces of the purple and pink stuff?
LOL....get lost.
There are techniques available in Photoshop that can do that. It can be tedious and time consuming, but it can be done. In the absolute worst case, you can blow up the image to the point at which you can edit individual pixels. By adjusting the brightness and contrast on an image, you can make a lot of the background noise go away. But when you do that, guess what? You get image elements that look EXACTLY like the the "61 1064" portion of the certificate number, with a very sharp demarcation between black and white. But the same process wasn't done on the final "1" of that number. It is very different.
I've spent a lot of time restoring old graphic images using Photoshop, and I've seen these things many, many times. Whatever document they were working from DID NOT HAVE THE NUMBER "61 10641" on it originally. The final "1" was created from within Photoshop probably using the text tool. By cranking up the contrast, that fuzziness around that number would have gone away, but they never bothered to do that.
