Reality Check – We accept your challenge Mr Zullo

Reality check has challenged Mr Zullo

What will Zullo do? He can chose to show how a ‘criminal investigation’ deals with information that contradicts its findings, or he can ignore it.

Either way, Zullo is faced with quite an unfortunate situation of his own creation.

Hermitian’s flawed 16 bit alignment

Our friend Hermitian insists that there is a 16×16 bit alignment rule even though his own data shows that 3 out of 9 layers, or only ~33% adhere to that rule. Not much of a rule. In fact, anyone who has studied the Xerox workflow would have realized that the alignment with the MCU (16×16 bit) was at 600 PPI, and therefore, a 8×8 bit at 300 dpi. This is why we see uniform adherence to a 8×8 bit alignment rule at 300 ppi but not a 16×16 bit. Why Hermitian believes that his ‘forger’ is so sloppy is beyond me as there is just nothing predictive in the dataset. One would expect about 9/4 or 2.25 layers to align randomly, we find 3 which is well within expectations.

Museum PDF 8 bit alignment

And the confirmations keep on piling up. Love it… If you know how to properly use Illustrator, it is not such a bad tool after all. But it never hurts double checking so I extracted the cm matrices and did the calculations using a simple spreadsheet and compared them with Illustrator. Oh and for Hermitian’s sake, you have to set the origin at the bottom left corner. Otherwise you will have to do a simple subtraction.

The museum PDF

(x0, y0) = (-3.36, -0.48) If you set the origin in Illustrator at the left bottom corner, the columns e-x0 and -(d+f-y0) match up.

8 bit alignment pictures

Process Select the objects, add an outline, red color and 1 pixel. Save as png and select 300 ppi. Open in photoshop. Set grid to every 8 pixels. Snap screenshots focusing on the top right corners.. I hope that this finally helps our dear friend Hermitian understand… Doing the simple calculations is more accurate and much easier… So Hermitian, did you forget to set the resolution to 300 ppi? I think you did as changing resolution in Illustrator can be quite painful. Apologies accepted 🙂

8 bit alignment

Status Strong

A poster named gsgs observed that two sides of each foreground layer aligned with 8×8 bit boundaries in the 300 PPI resolution, which is the resolution for the foreground layers. Realizing that the image was likely scanned at 600×600 PPI and then the JPEG was padded to align with 16×16 bits (MCU) in this resolution, you may understand why these become 8×8 bit alignments in the 300 PPI resolution.

The WH Long Form Birth Certificate indeed showed that 2 of its sides aligned with these 8×8 bit boundaries, the other two sides aligned with the inside of the image, in the sense that these lines were touching at least one pixel of the image.
