Does anybody know how to remove the pixels around the wording in a copy of a document. I am doing a diploma for somebody and I can not seem to get rid of the pixels in the background. I have done this before and it worked out fine. I scanned in a photo copy of the document. Any help here would be appreciated.

I've used the eraser very tediously in the past. I've also tried trace with some success. But both took longer than the job was worth.
I finally resorted to re-drawing all I could and erasing the other stuff.
As I recall I may have tried printing out the scan and re-scanning from white paper. I think all the pixels were a result of the original parchment paper the diploma was printed on.

Denny,
When you scan in the item, use the controls in the software to "Lighten" up on the contrast of the image. The software I use from HP it is called "Exposure Adjustment" and allows you to see a preview before you actually scan, so you can see if the "noise" is reduced.

Denny,
What method of removing a background worked in the past?
Have you tried a program such as "Knockout"?

Denny,
Since you did not mention the program you are using is hard to give you directions
I will tell you what I do in Photoshop which it may apply to other programs like Paint Shop Pro or Photo Paint
To enhance the document use the Brightness/Contrast adjustment so the black letters look blacker and what is white looks whiter, after this you can use the selection wand and select all the white then hit delete
Another way is, after doing the contrast adjustment change the mode of the document layer to Multiply and... like magic the white is gone!
I hope this is of help to you

Scan that portion of your certificate in black & white. If you need other portions of it grayscale, then scan two or more times and juxtapostion the components as needed.

Very nice looking plaque. Is that solid cherry?
