	I have been playing around with some of the new features of  
level 2 PS for the last couple of weeks.  I came across the  
interpolation feature of images and I was wondering if anyone had  
some simple examples.  I have tried (in vain) to get an interpolated  
image to produce a different result than an uninterpolated image. 


	Here is what I have been using to test:

--CUT HERE----CUT HERE----CUT HERE----CUT HERE----CUT HERE--
%!PS-Adobe-3.0
/DeviceRGB setcolorspace
144 144 translate 144 144 scale
<<
	/ImageType 1
	/Width 2 /Height 2 
	/BitsPerComponent 8
	/MultipleDataSources true
	/ImageMatrix [2 0 0 -2 0 2]
	/Decode [0 1 0 1 0 1]
	/Interpolate true
	/DataSource [<FF 00 00 00> <00 FF 00 00> <00 00 FF 00>]
>>
image
--CUT HERE----CUT HERE----CUT HERE----CUT HERE----CUT HERE--


	If you have any suggestions or examples I would appreciate  
them.


	Thanks,
