ADJUST
This lets you adjust the tonal range like in the "levels" dialog of Photoshop. You can set the input and output levels and that way remap the tonal range of the image. If you need to adjust the gamma value, have a look at the EFFECT object.
Example
20 = ADJUST
20.value = inputLevels = 13, 230Properties

inputLevels
-
- Type
- low, high (int<0,255>, int<0, 255>)
With this option you can remap the tone of the image to make shadows darker, highlights lighter and increase contrast.
Possible values for "low" and "high" are integers between 0 and 255, where "high" must be higher than "low".
The value "low" will then be remapped to a tone of 0, the value "high" will be remapped to 255.
Example:
This example will cause the tonal range of the resulting image to begin at 50 of the original (which is set as 0 for the new image) and to end at 190 of the original (which is set as 255 for the new image).

- Type
- low, high (int<0,255>, int<0, 255>)
With this option you can remap the tone of the image to make shadows lighter, highlights darker and decrease contrast.
Possible values for "low" and "high" are integers between 0 and 255, where "high" must be higher than "low".
The beginning of the tonal range, which is 0, will then be remapped to the value "low", the end, which is 255, will be remapped to the value "high".
Example:
This example will cause the resulting image to have a tonal range, where there is no pixel with a tone below 50 and no pixel with a tone above 190 in the image.
