| - | ====== Histogram Editor ====== | ||
| - | The histogram window is responsible for assigning transformations from image original values (in any range) to palette range [0, 255]. 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. | ||

| - | ===== Transformations ===== | ||
| - | |||
| - | * *None*: The default transformation doesn't map any values, leaving cell values "as is". | ||
| - | |||
| - | * *Linear*: This transformation will map linearly any values between the "from" and "to" ranges. | ||
| - | |||
| - | * *Equalize*: This transformation will construct a curve based on [[wp>Equalization]]. | ||
