Graphics explained

All PDF file do NOT have layers…

If the file was originally created with layers and the layers were preserved instead of flattened, the layers will be intact and accessible. A PDF will not contain layers unless the user specifically chooses to create/preserve them. Regardless of filters and/or compression. Don’t let the geek-techie-speak fool you. A DCT is simply a jpg – which is an unreliable, flat, raster, pixel graphic. Algorithms are used in almost all formats and techniques – it simply means a computation…in this day and time what isn’t? The White House has not mentioned compression, character recognition, etc. Character recognition will not work on an old file with cursive writing. It is also very unreliable – as you can see what little information it was able to pick up on
