Reading a graphic

[Bob Hollness]

Hi all, I have a problem that has me well and truly stumped, so I am hoping
that somebody here might be able to help!

I have a bitmap image on my form. It is black and white and has several
horizontal lines across the page. What I want to do is somehow read the
left and top position of each horizontal line so that I can then draw more
lines on top of this image.

Does anybody have any idea if this is even possible? Tips are more than
welcome!

Hi,

Use the bitmap classes getpixel method to find the lines.

Create a graphics object to draw on the bitmap. Graphics.FromImage
