Lost the original data for a curve, only have the image. Now needs to get
the data back.
Heard people can get it back using Gimp.
Anyone knows how?
Many Thanks!

remember someone ever talked about using Photoshop (Gimp) to reverse
engineer the curves.

数数象素数量，和你的scale对比，搞个公式就倒推data了

long time ago, i used a software called windig to get the data. You can
search and try it.
Or you can use matlab: first read the image in, then find the index for the
curve, then compare the index of each pixel of the image with the curve, and
store them in a matrix
