my apologies for the slow reply.  The nightmare bloody network was undergoing unscheduled maintenance so I needed several days to check all the options you suggested for me and was about to give up when I found this video which was the first of the very many I watched that actually covered every transform tool in simple language suitable for beginners and old fogies like me.

I did a couple of runs today using the control P and then control W options and got reasonable results

Hello The ancient one,

For a beginner to absorb a certain type of information, it is not enough for that information to be available. It takes time for there to be proper understanding and understanding. The curve for new learning is personal, so don't worry about the interaction time with this forum.

One step after another and slowly you go far.

I would like to highlight post #7 https://www.gimp-forum.net/Thread-Flattening-a-scanned-book?pid=37075#pid37075

"There is an old script by RobA that uses two paths and the Gimp curve-bend plugin.

The RobA site is gone, you can find via the Internet Archive. To save the hassle the script ra_curve-bend-between-paths.scm is attached. 

Unzip and put in your Gimp users scripts folder C:\Users\"yourname"\AppData\Roaming\GIMP\2.10\scripts

Needs a top and a bottom path following the curve. There is a maximum of 17 path nodes. Never going to be great with the example." - rich2005

In this same post you will find a link to a video of just about 3 minutes:
https://youtu.be/fOX5p5tMt6c

Also available in the attachment is the plugin that was used in the video (ra_curve-bend-betweeen-paths.zip)

The Transform tool is a good tool, but in this case you would have better results trying to apply the technique shown in the video.

Good luck!
