Mobile Scanning Apps: A look Into The Dark Side By: Joe C. Hecht – Code4Sale,…

Posted by jpluimers on 2015/04/15

Summary of the dark side:

Every app we tested saved the image in a grayscale JPEG format. Simply put, you scan your document, save it in “space saving” monochrome, then the app up-samples it to a now “space wasting” grayscale format, dials in a low quality lossy compression ratio to make you think you are saving space, and thereby throws away some of the pixels in your scan.

A very interesting read by Joe Hecht. Nothing new for old FAX, TIFF and PDF farts like me. Entertaining and hopefully teaching for the newer generations of software developers.

So if you ever do PDFs of paper scans:

  1. use monochrome
  2. use loss-less compression
  3. look at what FAX machines did back in the days for pixel perfect legal proof documents
  4. know about PDF/A
