Folks,

I am trtying to run some edge detection programs on a buncg of TIFFs. I need to find out the starting and ending of each row, and the corresponding pizel value. In other words, I have to read the raw data and determine if it is a 0 or a 1 (I am dealing only with greyscales). Can someone please help me out with this? To put it plainly, I have to access each row, and manipulate data depending on the value.

Thanks,
Siddarth
