byte displacement to user defined data pix_hdr
 

Initial value:

 GE_readHeaderPixel(fid, byte_align)
%
% pix_hdr = read_pixel_header(fid, byte_align)
%
% Loads the pixel header from the file with filed id fid
% and returns it as a structure. 
% if byte_align = 1 then 32-bit alignment (SGI, LX2 format)
% if byte_align = 0 then 16-bit alignment (Sun, 5.X format)
