I'm looking for a mathematical definition of this scale. http://docs.gimp.org/en/gimp-tool-levels.html says 0 is black and 255 is white. What's in between? Is 7 double the brightness of 6?
What is the luminance / brightness of each of the levels? Is it a logarithmic scale? -- "Life is either a daring adventure or it is nothing at all." - Helen Keller http://www.ChaosReigns.com Guns save lives. _______________________________________________ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
