I often scan images, and I usually do that as 200 DPI JPEG files. If I look at them in Gwenview (Linux image viewer) the text looks readable, and on 100% it looks perfectly sharp.
When I convert them into a PDF, using convert from the Imagick package and open that in Okular or Evince (Linux document viewer) the text looks blurry.
I wrote a little script that creates a HTML page with all the images and opens it in the browser. Firefox scales the images a little sharper than the PDF viewers.
Is there any way to get the PDF to scale the images sharply?
