BillDL - posted excellent suggestion to use nconvert to split the pages apart and replace page 1. It did exactly what I needed - except I am unable to recombine the pages once I get them together.
I got the nconvert as suggested.
nconvert -xall original.tif
it made 3 files - one for each page - I assume the pattern would continue for larger files:
I made a file called: list.txt and listed the pages I want in the new document - seemed the way to do this.
Then I ran the nconvert -multi command like this:
nconvert -multi -l list.txt -o newfile.tif
What it did here was make three new files:
These would represent the three pages I want in a new file. I can not figure out how to get them back together with this software. Am I missing something?
