When you zoom the document fully, every single text character is surrounded by a halo of pixellation.

I notice that as well, however, I think it may be an artifact of the JPEG compression. I use to work with images alot, and depending on the amount of compression, you could see this artifacting being introduced onto documents that were compressed from a RAW image, or higher quality Jpeg.

That is an artifact of compression.

I agree 100%. Anytime there is a major change in the presented color on a jpeg... it adds the unwanted pix distortion :/ jpeg, in my opinion is the best mid-ground to a picture... the main weakness is that every time you change/save it, is that you lose lots of quality.

If you folks are working with the copy I posted on this thread, you will find artifacting as it is a capture from the imbedded graphic file in the scripted original Flash viewer into a PNG file at screen resolution and then, when placed on my hosting site, it was automatically converted for size and web use to JPEG with a 70% compression ratio. It was posted for quick viewing on FR and not for the intention of any forensic scrutiny. PLEASE DO NOT MAKE ANY CONCLUSIONS FROM THIS IMAGE DATA!

We need to get a copy of the Raw image, without compression or file type conversion of any kind, if we can't get a hold of the original, before we attempt any pixe level examination.
