ktransform


syntax:
ktransform 1.0.1 (krpano.com - krpanotools 1.0.6)

    - transforms sphere to cube panoramas
    - rotates sphere panoramas
    - extracts a 2D view from a sphere panorama


syntax: 
  ktransform mode inputfile outputfile [rx ry rz [fov]] [options]


 mode ... cube6, hcube, vcube, rotate, view
          cube6  = transform to cube panorama images (6 images)
          hcube  = transform to horizontal cube panorama imagestrip
          vcube  = transform to vertical cube panorama imagestrip
          rotate = rotates a sphere panorama image
          view   = creates a 2d view from a sphere image

 inputfile  ... jpeg or tiff input image
                (only RGB8 and RGBA8 supported)
 outputfile ... jpeg or tiff output image template
                (path's will be created)
 rx,ry,rz   ... rotate angles in degrees
                (needed for view and rotate mode)
 fov        ... field of view in degrees
                (needed for view mode)

options:
-outsize=#x#    ... output image size 
                    (for cube modes only one argument #)
-oversample=#   ... render intern at # higher resolution and downsample
-inverse        ... inverse rotation

-jpegquality=#  ... set jpeg quality 
                    (0-100; default=85)
-jpegsubsamp=#  ... set jpeg color subsampling 
                    (444,422,420,411; default=444)
-jpegoptimize   ... optimize jpeg compression
-tiffcompress=# ... set tiff compression
                    (none,lzw,zip,jpeg; default=lzw)
-tempdir=#      ... set directory for temporary data

1. Convert a SPHERICAL panorama to a CUBICAL

ktransform cube6 inputimage.tif cube.tif

this command converts the spherical image

"inputimage.tif"

to the six cube side images, named:

"cube_l.tif" - left cube side image
"cube_f.tif" - front cube side image
"cube_r.tif" - right cube side image
"cube_b.tif" - back cube side image
"cube_u.tif" - up cube side image
"cube_d.tif" - down cube side image
