adjust_colors

Arguments:

Description:

Perform a global adjustment of colors on selected images.

Range of correct image values are considered to be in [value_min,value_max] (e.g. [0,255]).
If value_min==value_max==0, value range is estimated from min/max values of selected images.
Processed images have pixel values constrained in [value_min,value_max].

Default values:

brightness=0, contrast=0, gamma=0, hue_shift=0, saturation=0, value_min=value_max=0.

Example of use:

$ gmic image.jpg +adjust_colors 0,30,0,0,30

Command: image.jpg +adjust_colors 0,30,0,0,30
Command: image.jpg +adjust_colors 0,30,0,0,30
