Generate strips of an image suitable to be glued onto a sphere. See also: pnmmercator. More information: https://netpbm.sourceforge.net/doc/ppmglobe.html.

• Transform an image to strips that can be cut out and glues onto a sphere:

ppmglobe {{number_of_strips}} {{path/to/image.ppm}} > {{path/to/output.ppm}}

• Use the specified color for the areas between the strips:

ppmglobe {{[-b|-background]}} {{red}} {{number_of_strips}} {{path/to/image.ppm}} > {{path/to/output.ppm}}
