The image is 71x29 but is located on a very large 'vritual canvas' or
'page'. this identifies the location of the display from which the
image (not text) was selected.
Also in the above the pipe line was NOT used. You just saved the image
into a file and had identify read the result from that file
You may as well have used two seperate commands...
import test.miff
identify test.miff
To remove, reset the virtual page using +repage
import tiff:- | convert - +repage tiff:- | identify -
Ok, that solved my problem - thanks.
But I am still a bit confused. I understand the pipe in my 2nd line wan't
really piping anything, maybe I should have used ;
import test.miff ; convert test.miff pgm:- | ....
What I don't understand is how sending the output to a file and reading the file
is different than piping.

Att the +repage to remove any virual canvas in the convert.

Of course it doesn't. You are selecting an image, not making a X
windows text selection, which is completely different things.
I think you mised the gocr step - with the options you posted, this now works:
import tiff:- | convert - +repage pgm:- | gocr - | xclip -selection clipboard
and now that I see that import can create other formats, I can get rid of the
convert:
import pgm:- | gocr - | xclip -selection clipboard
Thanks again.
