WH 7535 8 bit alignments

Spurred on by Hermitian’s inability to do his own research I did some calculations for the WH Xerox PDF. I measured the top_x and top_y coordinate of the top left corner, transformed it to a 300×300 PPI grid and added the offset to show that the boundaries, as expected, align with 8 bit boundaries. I have not finished all the boxes. [Update: Finished the rest]
WH7535 LandscapeNote that the jpeg extends -3.36 and -1.2 outside the clipping mask or 14 pixels by 5 pixels in a 300 PPI frame.

I am getting really tired of having to do Hermitian’s work. What meaningful things has he contributed? Other than continuous confusions about trivial concept? Contrary to his recent claims that the boundaries do not proper align, I have shown that they do align at 8×8 and not always at 16×16.

PS: Let me clarify which sides I am looking at

If you open the raw Xerox PDF in Illustrator, it is shown in ‘landscape’ orientation and the 8 bit boundaries are at the top and left. If opening the preview version, the 8 bit boundaries are at the left and bottom, since the document has rotated 90 degrees counter clockwise.

    I haven’t had time to check your work. But before I take the time to do so I have a couple of questions. If you provide the expected answers then I won’t have to check your numbers because it would be a waste of time.

    First what do you mean by the WH Xerox PDF ? Do you mean that the print was actually made on the WH equipment? Or do you mean that the paper original was a printout of some LFCOLB PDF or JPEG file made on a Xerox WC outside the WH? Which Xerox WC model are you reporting on?

    Is your 8 x 8 grid congruent with the edges of the clipping mask or the edges of the larger page?

    Did you check the calculated distances with Illustrator and if so did you use the artboard rulers or the global rulers?

    In previous discussions of your PDF code you always described your page size as nominal 8-1/2 in. x 11. in. and the resolution as either 150 PPI x 150 PPI or 300 PPI x 300 PPI. So why this time is your page size all of a sudden much larger and now, for the first time, consistent with a resolution of 72 PPI x 72 PPI ?

    You do realize that the forger did all of his digital cut and paste on multiple pages of different sizes but with common resolution of 72 PPI x 72 PPI ? Looks like you finally got around to reading PDFReferenceXX.PDF.

    Your Illustrator screen shot of the landscape oriented certificate image is too small to read anything. Also you don’t show the link panel data for the background layer. What was the scale factor and rotation angle for the background layer as read off the link data?

    And you state that Preview rotated the image 90 degrees counterclockwise. Was that rotation automatic when the file was opened in Preview or did the operator manually apply the rotation after the file was opened in Preview. If the later was this rotation written to the Preview print to PDF file ?+

    Your screen shot shows the landscape orientation to be upside down relative to the orientation of the background layer of the WH LFCOLB image (before the image was placed into a new PDF document in Illustrator). So what was the orientation of this Xerox image before you opened the file with Illustrator?

    Xerox Work Centre 7535 scan of the WH LFBC printed out. And Hermitian, you can click on the image and bring up a larger version. How many times do you need to be told this?

    Is your 8 x 8 grid congruent with the edges of the clipping mask or the edges of the larger page?

    The latter of course.

    I just read of the corner values.

    Because I am showing it in Illustrator which hides some of these facts. Yes I know, you are probably still struggling with these concepts so I decided to simplify the cognitive load for you.

    Now that is ironic coming from the person who could not even look up the order of filters… There is no evidence of a forger or cut and paste. You are just blowing smoke.

    ROTFL… 0 degrees and 24 and 48% of course. What else? We have been through this so many times now…

    And you state that Preview rotated the image 90 degrees counterclockwise. Was that rotation automatic when the file was opened in Preview or did the operator manually apply the rotation after the file was opened in Preview.

    I am not showing the preview version but when opening, you notice the image is upside down. The person rotated the image 90 degrees and saved it. Of course, internally the images remained in the same position and were only rotated using the cm matrix or the page wide /Rotate command.

So what was the orientation of this Xerox image before you opened the file with Illustrator?

    There is no evidence that Illustrator ever touched the document. And yes, the orientation is 180 off, do you still not understand what caused this? It was not scanned upside down.

    How many more times do we have to revisit these issues my friend? By now they should be well understood by you.

    I am amazed that you do not even double check the numbers as you claim that you always doubt… You could have done this yourself, even with the limited tools you have🙂

    Do you mean 180 degrees?
