Hi, there,

I have an image having a line on it. The line has one-pixel width. The
approxiamate method to calculate the length of the line is like this:
the length is calculated as the sum of distances between adjacent pixels on
the line, where 1 is the vertical or horizontal distance between adjacent
pixels and sqrt(2) is the distance between pixels on diagonals.

My question is:
How can I trace this line and get the length of the line?

Any suggestion will be appreciated.

Regards,

Xiaoying Jin
