       Generates fulla command-line parameters for correction of  transverse  chromatic  aberration  (TCA)  from
       sample  photos.  Ideal  sample  photos  would  have  a lot of contrast over the entire image area, little
       saturated colour and no blown highlights.

-h  Display help

       -l  input file is PTO file instead of image

       -mmethod
           optimization method (0 normal, 1 newfit)

       -ooptvars
           string of variables to optimize ("abcvde")

       -r  Reset values (this will zero a,b,c,d,e params and set v to 10) makes sense only with -l option

       -s<scale>
           Scale for corner detection

       -n<number>
           number of points per grid cell (default: 10)

       -g<number>
           divide image in <number>x<number> grid cells (default: 10)

       -tnum
           Remove all control points with an error higher than num pixels (default: 1.5)

       -v  Verbose

       --save-into-database
           Saves the tca data into Hugin lens database

       -wfilename
           write PTO file

       -R<r>
           Use this file as red channel

       -G<g>
           Use this file as green channel

       -B<b>
           Use this file as blue channel

tca_correct [options] inputfile

       <inputfile> is the base name of 4 image files:

       <inputfile>
           Colour file to compute TCA parameters

       red_<inputfile>
           Red channel of <inputfile>

       green_<inputfile>
           Green channel of <inputfile>

       blue_<inputfile>
           Blue channel of <inputfile>

       The  channel  images  must be colour images with 3 identical channels.  If any of -R, -G, or -B is given,
       this file name is used instead of the derived name.
