ACV file format for gray scale curve is as follows

Bytes    Description
0-1      Magic Number??? always 1
2-3      # of curves (for gray it is alwasy 1) 1
4-5      # of points in the curve

6-7      Old value for first point on the curve
8-9      New value for first point on the curve

10-11    Old value for second point on the curve
12-13    New value for second point on the curve

and so on for each point on the curve.

"Old Value" means the original RGB value for that gray ranging from 0 
to 255. "New Value" means the RGB value obtained after printing the 
target ranging from 0 to 255. Also I assume in gray scale r = g = b.

RGB curve essentially the same but with 3 individual curve for r,g 
and b. These are from my observation. So verify it in a hex editor 
what I told is correct or not.
