Use of -levels2 options

[SAMSAM]

In the new version 7.70 of nconvert, the command "-levels2" has appeared, please help us understand the parameters of this command. The logic of these 5 parameters is not quite clear. Describe them in more detail and preferably with examples.

Referring to the Image > Adjust > Levels... display in XnView MP:

-levels2.png

Code: Select all

-levels b w     : Levels

The b and w parameters in the above NConvert option can be taken to refer to the top slider left and right window numeric values, I believe.

Code: Select all

-levels2 in_low in_high gamma out_low out_high : Levels

In the -levels2 option, the in_low, in_high, and gamma values can be taken to represent the top slider left, right and centre numeric values, and the out_low and out_high refer to the lower slider (labelled Output) left and right numeric values, I believe.

In the event of any confusion, a quick check of the resulting output images using XnView MP and NConvert should confirm correct operation.

Thank you, now everything is clear. Let's try ...
