Hi guys!
Ok, I've got a problem and I am sure one of you guys could help!
My application is working with PDF data that I import from a file.
These data are in color, and I would like to make a copy of this PDFRep
in grayscale, so that the user can switch from a grayscale view to a
color view by clicking a button. The PDF data are generated by the
user, so I can't simply "draw" a BW copy of it. Also, once the user is
happy with the Apps result (a plot application), he/she should be able
to save the PDF data and re-open it in a PDF compatible vector graphic
program, so I can't simply transform it into a TIFF image or something
else. I've tried all I could, and I must admit I am at lost on this
one. Can anyone give me a hint?
Thanks a lot in advance!
