I used GBA-Scanin software to scan in a color picture and store it in
Sun output format.  Then I shifted it to our Sun workstation.  Using
ALV package, I found that the configuration of the file is:
	xsize = 300
	ysize = 230
	depth = 8
But, the size of the file is 207800.  If we multiply 300 by 230, we
get 69,000.  So, I thought it must be stored as 3 bytes per pixel.
After I ran the r24r8 (developed by ncsa), I found the following
error: more bytes in file ../images/rat1.sun than dimensions indicate.
Note that r24r8 is a program quantizes a raw RGB 24 bit "pixel" image 
into a 8 bit image with RGB palette.  I can use "dsp" to display the
file.  But, what I got is only 1/3 of the picture.  Can anyone help
me figure out in what format this file is?  

Thanks in advance!
