PDF format is the de facto standard for companies to release electronic representations of paper documents. PDF files can contain an arbitrary mixture of bitonal, color, and grayscale bitmaps, along with an arbitrary mixture of text and vector graphics. I don't know to what extent automated tools will take a high-resolution bitmap and decompose it into different parts, but I do know that if utilities don't already exist that would turn a scan of a document that looks like the Obama COLB into a PDF similar to the one that was released, they should. In many cases, storing and distributing 1200dpi uncompressed scans of mostly-text documents would be overkill; in cases where file size is important, analyzing a source image and decomposing the parts that seem to be bitonal, grayscale, and color would greatly improve the efficiency by which a reasonable facsimile of a document could be stored and transmitted.
If you look at the PDF file that was on the wh website, Pay particular attention to the signatures of Obama’s mom and the Doctor.
Blow it up to 800 or 1000%. You’ll notice that the resuscitation for the two signatures is not the same... The dots per inch is different by a factor of four. The two signatures were obviously scanned at different reticulations. They are not text, and OCR is not a factor. They were different scans... If the signatures are phony, then the whole document to which the signatures verify is a phony...
I would appreciate your response.
