as i posted text file in first post....i want to make the following part of the file more clear...

! Define Keypoints
K,1,x1, y1 ! keypoint, #, x, y
K,2,x2, y2
K,3,x3, y3
K,4,x4, y4
K,5,x5, y5
K,6,x6, y6
in above part actually X1, Y1 have some values...so actually above part is like this in text file..except this everything is correct in file and written as i want to.
