LOL, reminds me of the fake one Something Awful was pushing a few years ago where the watermark was in Dutch and translated something like "Birthers are crazy". People need to understand that there are a lot of jokers out there (President included) who have been pushing crazy theories as a joke. Anonymous (the hackers) called this the "IRL hack of a lifetime" and Something Awful has been responsible for floating several fakes they later mocked people for believing. There also is the "African Press International" and Obama snippets jokes people believed for a while. There are a lot of Internet pranksters playing games with this and it is helpful to be as skpetical about what you want to believe as you are with what the Prez is pushing.
I think it is settled. There are few on our forum that will vote to re-elect our President, now.
It is such a shame as his Marxist policies have been so very successful.
But scanners can also be used by a particular program for a digital file size that is much more manageable.
If you open standard adobe acrobat or any of the higher grade forms of Adobe Acrobat above the free “reader” you have choices of how to create a pdf. One of those choices is with a scanner to “read” or “scan” the document. As you point out it automatically can deploy “OCR” (optical character recognition) to turn some of the intense graphic information into more compactly rendered digital information.
If posters have Adobe Standard they can open the create a pdf from a scanner and follow along. Under that choice, they can open a screen called “Configure Presets” where options such as “Make Searchable (Run OCR)” are configured in the standard addition to be automatically selected unless you turn it off.
Secondly, they can then open the Optimization Options sub-menu and then they see the options automatically selected:
Deskew: Automatic
Background Removal: Low (But still turned on for OCR changes, guys)
Edge Shadow Removal: Cautious (But still turned on gang)
Despeckle: Low (But still turned on)
Descreen: Automatic (on by default but who knows what this alters)
Halo Removal: On (We already knew the Marxist didn't have a Halo so this matters only a little)
What you have pointed out and even a neophyte like me can see by opening the program is that there is a reason why an Adobe Acrobat program can turn a 2mb scan into a 350kb pdf and that reason is that it automatically manipulates the image. In summary, if a person wants to make a reasonable size electronic version of a document and starts by opening Adobe Acrobat Standard, the default settings for the program produce the missing background looking like white-out, it produces the OCR where the program picks and chooses based upon recognition all or part of words to render as Test and other portions to render as pixels, and lastly probably does a lot a things that aren't inconsistent with leaving layers as observable from someone else opening the document.
This is especially true if we want to find an observed forgery. When we are surrounded by nails, every tool begins to look like a hammer.
