orthview reads in a HEALPix sky map in FITS format and generates an orthographic projection of it, that can be visualized on the screen or exported in a GIF, JPEG, PNG, PDF or Postscript file. orthview allows the selection of the coordinate system, map size, color table, color bar inclusion, linear, log, hybrid or histogram equalised color scaling, maximum and minimum range for the plot, plot-title etc. It also allows the representation of the polarization field.
