NAME

pto_var - change image variables inside Hugin .pto project files

SYNOPSIS

pto_var [options] --opt|--link|--unlink|--set "image variables list input.pto

DESCRIPTION

pto_var is a command line tool, suitable for inclusion in shell scripts, and allows the
change of image variables inside a Hugin .pto project file. Optimisation variables can be
set, altered, linked and unlinked, The following image variables are allowed:

position: y, p, r, TrX, TrY, TrZ
lens parameters: v, a, b, c, d, e, g, t
photometric parameters: EeV, Er, Eb, Vb, Vc, Vd, Vx, Vy, Ra, Rb, Rc, Rd, Re (Vignetting and response parameter will treated as group.)

The image numbers start with zero. If the number is missing this applies to the variables
of all images (In this case a special treatment applies to the position of the anchor
image). An exclamation mark before the variable will remove the variable from the list of
variables to optimised.

OPTIONS

-o|--output = file.pto
Output Hugin PTO file. Default: <filename>_var.pto

-h|--help
Shows help

--opt varlist
Change optimizer variables

--modify-opt
Modify the existing optimizer variables
(without pto_var will start with an
empty variables set)
Examples:
--opt y,p,r Optimize yaw, pitch and roll of all images
(special treatment for anchor image applies)
--opt v0,b2 Optimize hfov of image 0 and barrel distortion
of image 2
--opt v,!v0 Optimize field of view for all images except
for the first image
--modify-opt --opt !v will not optimize field of view.
--opt !a,!b,!c Don't optimise distortion (works only with
switch --modify-opt together)

--link varlist
Example:
--link v3 Link hfov of image 3
--link a1,b1,c1 Link distortions parameter for image 1

--unlink varlist
Examples:
--unlink v5 Unlink hfov for image 5
--unlink a2,b2,c2 Unlink distortions parameters for image 2

--set varlist
Examples:
--set y0=0,r0=0,p0=0 Resets position of image 0
--set Vx4=-10,Vy4=10 Sets vignetting offset for image 4
--set v=20 Sets the field of view to 20 for all images
--set y=val+20 Increase yaw by 20 deg for all images
--set v=val*1.1 Increase fov by 10 % for all images
--set y=i*20 Set yaw to 0, 20, 40, ...

--set-from-file filename
Sets variables to new values
It reads the varlist from a file
