Hi<BR>
<BR>
Thank you for your help. <BR>
<BR>
No, i dont have a list of indices.<BR>
I just used the LineConstIterator to draw a line between my two points. <BR>
now i need check the gray-level value between these two points and find the pixel with the maximun gray-level value on that line.<BR>
so i want my output to be an index.<BR>
should i make an if loop inside the while loop that checks for the highest value?<BR>
<BR>
Thanks . <BR>
