Signature on a transparent PNG
Turn a photo of ink on white paper into a cropped PNG with the paper removed.
The paper must be close to one flat color. Lined paper and shadows will leave specks. Raise tolerance carefully.
Photograph ink on white paper, then use this to crop the signature and drop the paper. The result is a PNG you can stamp onto another page. The paper needs to be close to one color. Lines, creases, and shadows stay behind as specks. This does not create a legal certificate.
