I am really sorry you see my questions as trivial, they are not meant to
be. Much of my difficulty is one of understanding the terminology used.
For example and, assuming I understand correctly, if I scan a photograph
which is, say, 5 inches square and then display that scan on my monitor,
it will measure 24,000 pixels X 48,000 pixels. To test this on my rather
cheap Canon LIDE20 I scanned a picture which is 5 inches square saved
the file, opened the file in GIMP, cropped so that only the picture was
there and GIMP said it was 729 pixels X 729 pixels.
Please explain and, just in case you think I am some youngster trying to
get his homework done, I was 81 years old last birthday.
