I want to remove single color in Set Gray Point in curves ! In this script only add curves layer

I want to remove single color in Set Gray Point in curves ! 

---

Could you explain what you mean by that?

Posting screenshots might save you some typing. 

[MXKS]

Step :- 1

Step :- 2

I am using Gray Tool in Curve , To Remove any single color, So I want to automatic in scripts

[c.pfaffenbichler]

Automatic what? 

Where is the gray point supposed to be set? A fixed pixel position, a Color Sampler, …? 

[MXKS]

I want to set automatically gray point whicever color ?

[c.pfaffenbichler]

Please try to actually explain what you are trying to achieve. 

Are all the images just one solid color area each? What good would applying Curves (Layers) to those be? 

[MXKS]

First Image Check It, I want apply Gray point of Eyedropper tool by Curves. To Adjustment the Single Color.

Step1:- Open Image

Step2:- Avarage Color

Step3:- Open Curves

Stpe4:- Aplly Gray Point of Eyedroper tool by Curves

These four step I want to automstically in scripts

[r-bin]

Try Image->Adjustments->Match Color - tick Neutralize.

[MXKS]

Yes @r-bin  That is perfect But I want Curve Layer Using Gray Tools, Is that possible to scripts !

[r-bin]

Yes, but, I don't have time for this.

There is no ready-made code and the code will be long.

Maybe  Kukurykus wrote a short one in his own unrivaled style. : )

[MXKS]

Please write the code

[MXKS]

Just Write 2Step Code:- 

1- Add Curves

2- Gray Point in Eyedroper tools by Curves

[r-bin]

Add.

Moreover, it is not clear whether you want to turn the average color into (128,128,128) or just remove saturation from it. Curves can be curves, linear or charcoal. The question is ambiguous, because the final goals in real images are not clear.

[MXKS]

Yes That is final goals, Please write the code :-

Add the Curve Layer in below scripts---

Can you set a Gray Point By Curves:- 

var desc6 = new ActionDescriptor();
var desc7 = new ActionDescriptor();
var desc8 = new ActionDescriptor();
var ref2 = new ActionReference();
ref2.putClass( charIDToTypeID( "AdjL" ));
desc6.putReference( charIDToTypeID( "null" ), ref2 );
desc8.putEnumerated( stringIDToTypeID( "presetKind" ), stringIDToTypeID( "presetKindType" ), stringIDToTypeID( "presetKindDefault" ));
desc7.putObject( charIDToTypeID( "Type" ), charIDToTypeID( "Crvs" ), desc8 );
desc6.putObject( charIDToTypeID( "Usng" ), charIDToTypeID( "AdjL" ), desc7 );
executeAction( charIDToTypeID( "Mk " ), desc6, DialogModes.NO );

// =======================================================
var desc10 = new ActionDescriptor();

var desc12 = new ActionDescriptor();
var desc13 = new ActionDescriptor();
var desc9 = new ActionDescriptor();
var list1 = new ActionList();

ref4.putEnumerated( charIDToTypeID( "Chnl" ), charIDToTypeID( "Chnl" ), charIDToTypeID( "Cyn " ));
desc11.putReference( charIDToTypeID( "Chnl" ), ref4 );
desc12.putDouble( charIDToTypeID( "Hrzn" ), 0.000000 );
desc12.putDouble( charIDToTypeID( "Vrtc" ), 0.000000 );
list2.putObject( charIDToTypeID( "Pnt " ), desc12 );
desc13.putDouble( charIDToTypeID( "Hrzn" ), 229.000000 );
desc13.putDouble( charIDToTypeID( "Vrtc" ), 229.000000 );
list2.putObject( charIDToTypeID( "Pnt " ), desc13 );
desc11.putList( charIDToTypeID( "Crv " ), list2 );

Here is the code The get_average_color function can be found here Get color from selected area

var c = new SolidColor()

var r = c.rgb.red;

Thanks @r-bin  I will try

[Kukurykus]

Why this answer was marked as correct if it's not a solution to the problem?

[Kukurykus]

You look at it wrong way. It's like 2 different people listen to different music, and the one that likes Jazz, cannot understand the other prefers Hip Hop. Or going deeper true street hip hop and luxury's or else Smooth Jazz against Classic Jazz. Similary how can you want to be white when I am happy beeing black 😄 It is funny you do not do something the way I do, really?
