HOW TO... Edit text and extract images from scanned documents

摘要

There's a wide range of apps for scanning documents with your phone, many of which detect the edges of documents you point them at, then extract the text. If you need to capture text for research purposes in the library, they're a cheaper alternative than paying for photocopies. They're not for everyone, though, and if you have a scanner, or all-in-one printer with a built-in scanner on top, using that may be a better option.
