i am plotting a line in VB.NET on a Picturebox image (which is a white image with some black lines). The problem is i need to know if my line passes through some line (obstacle) in the image. So at each pixel while drawing the line i will have to check the pixel at each point and whether the pixel is of the colour of the obstacle or not. how can i achieve this?
Any help will be appreciated
