ge is a struct with fields:
ge.hdr.suite - suite header
ge.hdr.exam - exam header
ge.hdr.series - series header
ge.hdr.image - image header
ge.hdr.pixel - pixel header
ge.img.offset - the byte offset to the image data
This function assumes the image file is big endian. It can
automatically determine LX2 format (SGI) and 5.X format (Sun);
other formats fail.
