In short: Hermitian looks in depth at the affine transforms and re-discovers that which I had already discovered and posted on. But he lacked somehow the preview generated PDF which of course matches exactly what we see in the WH LFBC PDF. You cannot compare apples and oranges unless you want to create a ‘smoothie’
The following six-vector was extracted from the archived copy of the file “birth-certificate-long-form.pdf” by means of Adobe Acrobat XI Pro Preflight.
0 -792.96002 612.47998 0 -.24 792.47998 cm
Thus the form of this six-vector is:
[0 b c 0 e f]
his form for the six-vector is consistent with a rotation of -90 degrees (clockwise) provided that the skew angles alpha and beta are both zero. A rotation of 90 degrees clockwise for each of the nine objects is consistent with the rotation angles read out from the Link panel data in Adobe Illustrator from the same PDF file. The rotation angle was 90 degrees clockwise for each of the nine image layers.
So far so good, yes, as I have been explaining for some time now, the instructions rotate the images 90 degrees clockwise as they are stored in “landscape”.
ll of the findings reported here were obtained by means of Adobe Acrobat XI Pro Preflight. The extracted transformation six-vector for the Xerox created background image layer is:
798.71997 0 0 614.40002 -3.36 -1.2 cm
Contrary to the form of the corresponding six-vector of the background image of the WH LFCOLB PDF image, the form of the Xerox six-vector is:
[a 0 0 d e f]
Hence unlike the WH LFCOLB six-vector, where a and d were zero, instead we find in this case that b and c are both zero. All six-vectors of all seventeen objects in the Xerox file have this same form.
Yes also exactly as I had show… But Hermitian is comparing apples and oranges. What he needs is the Preview saved version which shows:
0 798.72 -614.4 0 613.2 -3.36 cm /Im1
Same rotation/scaling form as the WH PDF…
0 -794.88 614.4 0 -1.2 793.44 cm /Im1
Thanks for proving my point… And you dropped the /XIPLAYER0 which is a tell tale sign that these are different objects… /Im1 is the standard used by Preview, /XIPLAYER is used by Xerox…
Oh and the cm for the upside down version, rotated 180 degrees?
0 -792.96002 612.47998 0 -.24 792.47998 cm /XIPLAYER0 0 -794.88 614.4 0 -1.2 793.44 cm /Im1
All of these findings are consistent with the PDF file having been created with Adobe Illustrator.
And with Xerox Work Center with the added benefits that I can show that the images contain exactly the elements that indicate a Xerox Work Center…
