reading jpg image pixel values
Posted on 2004-11-30
OK, here is what I have...
I have a program that scans via twain image driver.
We have what is called a routing slip similar to a scantron where people are coloring in circles.
I want to be able to read pixel values from any point. because we are scanning at such a high resolution the image goes outside of the visible picture box.
my problem is that I cannot read any part of an image that is not visible in a picture box.
my goal is to read pixel rgb values given an x,y coordinate in pixels for any point in the image without dealing with a picture box or external dll objects.
we are using this object as an activeX web object.
Thank you so much for all your help
