[Q] Set Brush Smoothing value by script (CC 2018 feature)

[Naoki-Hada]

Hi all,

I'm struggling to set value on Brush's Smoothing on Photoshop UI part as below.

From XTools' Getter.jsx file, it seems Smoothing is exported as following as same level of Opacity and Flow.

XTools: xtools

So I tried to modify from code from changing Opacity from following and the modified code.

JavaScripts/SetPaintBrushOpacityAndOthers.jsx at master · TomRuark/JavaScripts · GitHub

// Code from :  
// https://github.com/TomRuark/JavaScripts/blob/master/SetPaintBrushOpacityAndOthers.jsx
var idset = stringIDToTypeID( "set" );
var desc226 = new ActionDescriptor();
var idnull = stringIDToTypeID( "null" );
var ref170 = new ActionReference();
var idPbTl = stringIDToTypeID( "paintbrushTool" );
ref170.putClass( idPbTl );
desc226.putReference( idnull, ref170 );
var id12 = stringIDToTypeID( "to" );
var desc5 = new ActionDescriptor();
// opacity
var id13 = stringIDToTypeID( "opacity" );
var id14 = stringIDToTypeID( "percentUnit" );
desc5.putUnitDouble( id13, id14, 88 );
// flow
var id19 = stringIDToTypeID( "flow" );
desc5.putUnitDouble( id19, id14, 77 );
// TEST: smoothing: Not working
var id99 = stringIDToTypeID( "smooth" );
desc5.putUnitDouble( id99, id14, 66 );
var id18 = stringIDToTypeID( "null" );
desc226.putObject( id12, id18, desc5 );
executeAction( idset, desc226, DialogModes.NO );

Opacity and Flow can be set the value.

Smoothing is not working.

I still don't understand well on the ActionDescriptor's code and still learning.

Any help, suggestions, tips, links are appreciated.

Thank you,

Naoki

This does not work in CS6, so I'm not particularly interested.
In CC2018, you can use this

// smooth_value = 66;

desc5.putInteger (stringIDToTypeID ("smooth"), smooth_value);
desc5.putDouble (stringIDToTypeID ("smoothingValue"), Math.round (smooth_value / 100 * 255));


By the way, "flow" and "opacity" have type INTEGERTYPE, and not UNITDOUBLE as you use.

upd.

also you can set

"smoothing"

"smoothingRadiusMode"

"smoothingCatchup"

"smoothingCatchupAtEnd"

"smoothingZoomCompensation"

to BOOLEANTYPE (true or false)

Adobe merged old smoothing and new smoothing.

You can disable it "smoothing": true/false or reset to default value. http://sklad.bereza.cz/00-jarda/00_screenshot/2017-10-20_003537.jpg No matter which value you put. It probably always will be 10 %

Hi Jarda,

Thank you very much for the tips. I've seeing the reset to 10% behavior.

Also thank you very much for sharing ActionManagerHumanizer code.

It is very helpful.

Thank you,

It is very helpful.

I updated this tool to version: 0.2 and added some examples:

Hi Jarda,

Thank you very much again for the update.

I've verified the reset issue. It seems "smooth" is taking the setting value, but "smoothingValue" is required some value.

// verified working on Photoshop CC 2018
#include Humanizer-0.2.jsx
var smoothing_value = 34;
var desc = {
    "null": {
        "_ref": "paintbrushTool"
    },
    "to":{
        _obj:"currentToolOptions",
        _value: {
            "smooth":smoothing_value, // setting value
            "smoothingValue":true // Need some value here. It does not work without this line.
        }
    }
};
try{
    var descMod = Humanizer.objectToDescriptor(desc)[1]; // ActionDescriptor
    var descResult = executeAction(stringIDToTypeID("set"), descMod, DialogModes.NO);  // ActionDescriptor
    $.writeln("---descMod------------------");
    $.writeln(Humanizer.descriptorToJsonString (descMod));
    $.writeln("---descResult-----------------");
    $.writeln(Humanizer.descriptorToJsonString (descResult));
    $.writeln("---------------------");
}catch(e){
    $.writeln("EXCEPTION: " + e);
}
$.writeln("debug break");

Thank you very much for the code ().

I verified it is working on CC 2018.

Both line seems required. I found "smoothingValue" in below same section of Getter.jsx XML file.

Updated code.

var idset = stringIDToTypeID( "set" ); 
var desc226 = new ActionDescriptor(); 
var idnull = stringIDToTypeID( "null" ); 
var ref170 = new ActionReference(); 
var idPbTl = stringIDToTypeID( "paintbrushTool" ); 
ref170.putClass( idPbTl ); 
desc226.putReference( idnull, ref170 ); 
var id12 = stringIDToTypeID( "to" ); 
var desc5 = new ActionDescriptor(); 
// smoothing: verified working
var smooth_value = 66;
desc5.putInteger (stringIDToTypeID ("smooth"), smooth_value);
desc5.putDouble (stringIDToTypeID ("smoothingValue"), Math.round (smooth_value / 100 * 255)); 
var id18 = stringIDToTypeID( "null" ); 
desc226.putObject( id12, id18, desc5 ); 
executeAction( idset, desc226, DialogModes.NO );

And the smoothingValue part in Getter.xml

Thank you,

Naoki
