Adjust Pixel values

Image Statistics Menu: Options > Adjust pixel values
Array Analyzer
Menu: Data > Adjust pixel values

Allows modifying image pixel values before calculating statistics on them. Because the darker pixels in an image have the lower values, sometimes inverting the pixel values may be desirable.

The range the pixels values have or scale, usually is 0 to 255 (or 0 to 359 in Hue channel and 0 to 100 in Saturation or Brightness channels). If a Conversion Factor is set, all values are going to be mapped to an scale between 0 and the Conversion Factor set.

Warning: Because pixel values are mapped to integer values, an small range (like 10) is going to reduce the accuracy of the data.
