adjust_colors
Arguments:
- -100<=_brightness<=100,-100<=_contrast<=100,-100<=_gamma<=100,-100<=_hue_shift<=100,-100<=_saturation<=100,_value_min,_value_max
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:
Command:
image.jpg +adjust_colors 0,30,0,0,30
Command:
image.jpg +adjust_colors 0,30,0,0,30
