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.
