distance between two pixels using VB.
Posted on 2001-07-18
I have a BW scanned image that is saved as a bmp, basically I want to figure out it's length by measuring the top-most black pixel and the bottom pixel. How do I find these pixels? I also would like to find the width at a certain number of inches, pixels, or whatever down the image. How do I do this also? I figure it would be easy if I started at the top left pixel and scaned row by row till I found a black one but I have no idea how to do this. Can someone help me?
Thanks in Advance,
