I've found and implemented the following code to display external JPEG
files and it works well:

300 300 translate
100 100 scale
/DeviceRGB setcolorspace
% myfile.jpg is a 100 x 100 jpeg
/infile (c:\\temp\\myfile.jpg) (r) file def
/Data {infile /DCTDecode filter} def
<<
       /ImageType 1
       /Width 100
       /Height 100
       /ImageMatrix [100 0 0 -100 0 100]
       /DataSource Data
       /BitsPerComponent 8
       /Decode [0 1 0 1 0 1]
>>
image
showpage

But when I execute the same code with a TIFF file, substituting /
RunLengthDecode for the encoding, all I get is a one pixel high line.

I suspect I'm not using the correct filter or have made some other
mistake in one of the many portions of the image matrix but after
several days, I have been unable to determine how to make it work.

If anyone knows where I've made my mistake, please let me know.

Thank you

Alan
