a long horizontal bar to scan an image

February 10, 2013 | 1:02 am

I was wondering how do I go about scanning and extracting values from an image from top to bottom – for example, where physically a long horizontal bar will slowly move down the image ?

I know how to extract pixel data from an image but I can’t seem to figure out how to properly scan (where I could actually see the scanning bar or something like moves top to bottom ) an image that automatically gives me the values.

lots of ways to do this, easiest might be jit.submatrix.

i think an c# image scanner will help you to retrieve values and pixel, so you don’t need a bar. it will do immediately after a click.
