there is an option under BATCH to "optimize alignment" that has 7 options to it
fit f
fit aspect
fit cx, cy
fit skew
fit k1, k2, k3
fit p1,p2
fit k4
there is a yes or no option for each
where can I find out exactly what each of these variables are( what is cx,cy, k1...etc) and what effect will it have on the output file?
