---|---|---|
Contraste |
Float |
Set the contrast expression. Negative values give a negative image. The value must be a float value in range -3.00 to 3.00. The default value is 1.00. |
Brillo |
Float |
Set the brightness expression. The value must be a float value in range -1.00 to 1.00. The default value is 0.00. |
Saturación |
Float |
Set the saturation expression. The value must be a float in range 0.00 to 5.00. The default value is 1.00. |
Gama |
Float |
Set the gamma expression. The value must be a float in range 0.00 to 3.00. The default value is 1.00. |
Gama rojo/verde/azul |
Float |
Set the gamma expression for red, green or blue. The value must be a float in range 0.00 to 3.00. The default value is 1.00. |
Intensidad gama |
Float |
Set the gamma weight expression. It can be used to reduce the effect of a high gamma value on bright image areas, e.g. keep them from getting over amplified and just plain white. The value must be a float in range 0.00 to 1.00. A value of 0.0 turns the gamma correction all the way down while 1.00 leaves it at its full strength. Default is 1.00. |
