erect2cubic might help here: erect2cubic Takes an equirectangular image and produces a .pto file suitable for extracting six cube faces.
Usage: /usr/local/bin/erect2cubic --erect=myerectangular.tif --ptofile=cubic.pto Options: --filespec (panotools format, defaults to 'TIFF_m') --roll (degrees) --pitch (degrees, use -90 if nadir is in centre) --yaw (degrees, adjust position of first cubeface) --face (cubeface size in pixels, defaults to optimum) On 11 June 2012 16:16, Carl von Einem <c...@einem.net> wrote: > In the upper areas of an equirectangular image the information is so > compressed that it's not easy to use clone tools etc. > Usually it helps to reproject to cube faces which have a rectilinear > projection and cover 90 x 90 degrees.
