I am tracking a score sheet for features explained versus objections raised.
August 28 A sad day as I have decided to no longer allow Hermitian to submit comments on this blog as he has now, several times accused me of behavior for which he has no evidence (hinting that I may be the forger, work for Obama, that I withhold data or manipulate data and other non sequiturs). I feel saddened because, despite his short comings, he did serve a useful purpose. I wish him well and will continue to address issues he raises, to help him understand better why the Xerox workflow stands unassailed. Thank you Hermitian for your efforts to debunk the work flow, helping further strengthen it.
August 26 Hermitian, now continues to explore his earlier failures to properly understand, and has returned to such trivially wrong claims as: The 7655 does not produce the same Quantization Matrix (it does), or decompressing a FlateDecode encoded image somehow changes the ‘image’ when in fact it is a trivial experiment to show that saving in Preview does not cause preview to rewrite the JPEG (DCTDecode) object but just copies it. Trivial and minor details that just outline how much our friend has yet to learn about PDF. Speaking of that, has he managed to finally extract the JPEG from the FlateDecode\DCTDecode object :-). The one that shows the YCbCr comment?… The same comment Preview politely leaves in place when rewriting the PDF… Well, at least our friend now considers that the 7535 is a better candidate for the ‘forger’ so at least he helps supporting the Xerox Workflow, although I believe he has yet to understand why I concluded Xerox 7655 as the most likely candidate. He also continues to fail to understand how one can determine the orientation of the document when originally scanned. I encourage his continued questions, even though they have become mostly irrelevant, as it helps strengthen the explanatory power of the workflow. So, has he given up on trying to debunk the work flow?
August 22 Hermitian is struggling with the hierarchy of objects in the PDF document, something which could be quickly evaluated using a proper parser. He also appears to be obsessed by me ignoring his color fringes comment since we do not need to look for this to understand the orientation of the document when it was scanned.
August 21 Hermitian is now focusing on minor spelling mistakes about ppi and dpi and insists that I scan at 1200 ppi on a Xerox WorkCentre, even though the maximum ppi is 600. His claims about 16×16 bit alignment at 300 ppi have been destroyed by his own data. Surely he must have some real objections to my findings…
August 20 We have halos… Two more PDF’s and the last one had some beautiful halos. Seems we are all done. Hermitian is running out of objections and we should soon have helped him understand his latest follies. Seizethecarp at the Freerepublic appears to understand my contributions. The ‘Cold Case Posse Supporter’ is banking his hope on Reed Hayes. Even though noone has seen this report yet… Butterdezillion is in full denial mode and soon will probably argue that me showing that Xerox did all this, is evidence that it didn’t. So when will a birther dare to look for him/herself?
August 19 More PDFs have been found, again they match the details found in the WH LFBC, such as 8 bit alignment, presence of the YCbCr comment tag and quantization matrix. It is fascinating how these findings continue to strengthen the Xerox Workflow hypothesis. A minor issue has been detected by Hermitian, who observed that the Preview pdf’s are scaled 96%, which is the default behavior of Preview. I will redo some of the preview documents at the 100% level as well.
August 18 Today has been another great day. Two new PDF’s were found that were scanned on Xerox. They show the YCbCr comment and align at 8 bit boundaries. Hermitian appears to not understand the workflow that created the edge erase and clipping mask. Hermitian’s earlier claims that the 7535 documents do not align at 8×8 bit boundaries remains unsupported by any data. His claims, trying to dismiss the YCbCr comment, have been rejected as he has failed to show any examples that are not Xerox WorkCentre related. So far, the evidence is growing the strength of my workflow.
August 17 Hermitian so far insists, against the evidence so far, that my images do not align properly with 8×8 bit boundaries. Let’s see if we can help him locate his errors. I will see if I can help him further but it is somewhat frustrating that we get entangled in simple misunderstandings rather than meaningful objections.
August 16 Another disappointing day as Hermitian continues having problems with getting details right about alignments and sizes. Needless to say, Hermitian is still ignoring how so many features all match. Instead he prefers to share with us his skills at moving the goal posts.
August 15 Hermitian has yet to raise any challenges to my workflow. He has made some ‘interesting’ claims that were easily corrected.
August 14: So far, our friend Hermitian has challenged the alignment, even though I have shown that they consistently align with 8 bit boundaries, and he has been unable to recreate the simple workflow to extract the YCbCr jpeg comment, and instead has suggested that it was somehow ‘forged’.
So far, a single, straightforward workflow continues to beat other hypotheses without any problems, mostly because here are no other viable hypothesis presented other than a ‘forger’ who did exactly what he did and ended up mimicking a Xerox workflow.
