Firstly, my apologies for being sligtly off topic since this does not pertain directly to progamming, but only programmers would know.

There's a lot of bitmap data floating around the market, which pay you to enter such data into a text format. Apparently the software that generated these can export bitmaps, but not the data directly, requiring humans to manually type it in again.

I did some research online, and it appears both SAP and Lotus 123 can export data, with little or no restrictions. Could it be these or something else? Can you identify the legacy software that created such data?

有帮助吗?

This looks like a scanned image of a printed paper.

Circumstantial Evidence:
--I blew up the image and the characters like "C" are not identical. This suggests printed ink.
--There is noise around the letters. This suggests a paper was scanned and/or bits of ink.

The evidence does not conclusively prove that it is a scanned paper. But I don't see the point in intentionally generating noise and inconsistent fonts in an image.
