-# Convert "arbitrary" image files to rgb files (SGI's image format).
-# Input may be compressed.
-# The uncompressed file type may be PBM, PGM, PPM, GIF, TIFF, or Sun raster.
-# An exception is raised if the file is not of a recognized type.
-# Returned filename is either the input filename or a temporary filename;
-# in the latter case the caller must ensure that it is removed.
-# Other temporary files used are removed by the function.
