I have made a few tools for manipulating digital negative curves, images and test charts while working on my lcd enlarger (lcd thread: https://www.photrio.com/forum/threads/diy-31-megapixel-enlarger.197305/ ) There is an Adobe ACV curve, AMP pencil curve and CSV cmdline manipulator, and a calibration chart reader and parser. The noteworthy thing about the chart tool is that it allows multiple sample patches per value that can be randomly scattered about the test chart to try offset the effects of uneven illumination.
They were made for my own use, and they are a work in progress. I prefer to use Linux, but my mono lcd runs on a cheap Windows 10 PC, so those are the two systems I have tried things on. If you try it and spot problems, let me know. The project is here:
