Dear List
I have come across a problem which I don't think is due to ConTeXt but
I'm hopping the great and the good of this list may be able to explain
what is going on.
The code below produces an MPpage with a shaded background and two
graphics along with a line of outlined text. When I view in Adobe (or
the output from TeXworks) I see everything as it should be. However, I
wanted to convert the MPpage to a jpeg file and when I opened the pdf in
either Apple MAC Preview or Gimp 2.10 the two graphics are missing, and
I have no idea why.
Could someone explain a way round this? Here is the code.
Thanks
Keith
