Good day all.
In my spare time I convert photos or scans of rare technical documents to readable PDF files. Many of the photographs originate with unknown persons and I receive them third or later hand and the quality is what is politely called poor - see a typical example below where I have roughly edited out fingers at the top.
For some time I have been addressing warped pages photographed by persons unknown by using PerspectiveCropper to basically get all the corners about where they belong and then using ScanTailor to convert the images into clean PDF documents.
Because my eyesight is failing I can no longer do this as the handles for both programs are too small for me to see.
Today I tried GIMP to do my editing for the first time and the basic GIMP workflow I found to manipulate the images is fantastic. ➤ Filters, Distort, Curve bend.
That said I immediately ran into two major problems in that:
1. I am having to work with what I would call a thumbnail of the image I need to manipulate and with my eyesight that is just not practical - especially as the images tend to be dark with little contrast so I cannot see what is happening. I could not find a way to make the Curve bend control panel/palette full screen.
2. I did not manage to make the distorted "diamond" shaped page square
Obviously my most important question is - How to make the Curve bend control panel/palette full screen?
That may well solve problem two but if it does not then how do I drag the outside corners to square up the page?
I am using GIMP 2.10.38 on Win7 Enterprise
Thank you
