Ridiculously odd question: Measuring Area

[Sigurd]

I don't think its ridiculously odd, I think its keen and insightful and shows a brilliant mind and attention to detail - I asked the same question last June...

The cheap and cheerful way is to download a copy of paint.net. This is actually a very flexible free graphic editor, but for this you want its selection tool. Open your image in the program select the area and look at the lower left corner of the screen --- # of square pixels.
You can select for contiguous areas or draw with a lasso type tool.

Other solutions exist but mostly cost money. The downside, I think, is that pixels are wider than they are tall some other methods report different area.

Autocad has an area calculator that seems to consistently report bigger numbers.
Creative Cartographer (another cad based app) also has an area calculator.
Gimp and Photoshop both give you information in their Histogram window that can help you calculate # of pixels - best refer to link....

Finally for a nuts and bolts example here is a thread on the Harn site Lythia.com that has people solving the problem with Autocad.
