The histogram curve will adjust any value smaller than the "From:" limit to 0, and any value greater than the "To:" limit to 255. Any other values will be mapped using the histogram curve to the "Y" coordinate on the color palette on the left. {{ :map_viewer:histogram.png?nolink& |}} ==== Transformations ==== * The default transformation doesn't map any values, leaving cell values "as is". * Linear transformation will map linearly any values between the "from" and "to" ranges. * Equalize will construct a curve based on [[http://en.wikipedia.org/wiki/Equalization|Equalization]]
