I'm looking for a way to detect points/pixels on an image, according to a data I get from the user.
I want the user to scan an item barcode, and by that- to find the relevant item in the image and mark it (I can settle with a red dot or something ..)
for example, if I have on my screen an image of a desk with a pen, a notebook and a stapler and now the user scan the barcode on (a real) pen, it will mark the pen on the image.
I guess I need to adjust the x,y of each item of any item on the image I want to find but then I ask myself how can I do it relatively (if the the user change the screen resolution for example)
Any idea how can I do that?
I think I rather use winform and not webform since the software suppose to be in a specific computers .
