Modifying a gradient fill with a script

  • March 3, 2022

Hello,

I'm looking to automate a process where I need to have a gradient fill layer modified. Is it possible to modify the Angle at which the linear gradient is applied. I know the values can go from 0-359 but is there a command to actually modify its value with one of the javascript command?  I couldn't find any directly related to a gradient angle. 

Thanks!

Have you used ScriptingListener.plugin to record the operation as AM code? 

// 2022, use it at your own risk;
changeAngleOfGradientLayer (30);
function changeAngleOfGradientLayer (theAngle) {
try {
var idset = stringIDToTypeID( "set" );
    var desc5 = new ActionDescriptor();
    var idnull = stringIDToTypeID( "null" );
        var ref1 = new ActionReference();
        ref1.putEnumerated(stringIDToTypeID( "contentLayer" ), stringIDToTypeID( "ordinal" ), stringIDToTypeID( "targetEnum" ));
    desc5.putReference( idnull, ref1 );
    var idto = stringIDToTypeID( "to" );
        var desc6 = new ActionDescriptor();
        var idgradientsInterpolationMethod = stringIDToTypeID( "gradientsInterpolationMethod" );
        var idgradientInterpolationMethodType = stringIDToTypeID( "gradientInterpolationMethodType" );
        var idperceptual = stringIDToTypeID( "perceptual" );
        desc6.putEnumerated( idgradientsInterpolationMethod, idgradientInterpolationMethodType, idperceptual );
        var idangle = stringIDToTypeID( "angle" );
        var idangleUnit = stringIDToTypeID( "angleUnit" );
        desc6.putUnitDouble( idangle, idangleUnit, theAngle );
        var idtype = stringIDToTypeID( "type" );
        var idgradientType = stringIDToTypeID( "gradientType" );
        var idlinear = stringIDToTypeID( "linear" );
        desc6.putEnumerated( idtype, idgradientType, idlinear );
        var idgradient = stringIDToTypeID( "gradient" );
    var idgradientLayer = stringIDToTypeID( "gradientLayer" );
    desc5.putObject( idto, idgradientLayer, desc6 );
executeAction( idset, desc5, DialogModes.NO );
} catch (e) {}
};

    Sorry for the slow reply, new job came in and had to put my project on hold for a few days.

    Also, thanks for the tip. I'm no javascript coder and still hardly get by modifying some basic commands on premade script to try and fit what I'm looking for, mostly by addition of some if/else check. I wasn't expecting something so complex 😉

    From what I understand, this is the code that scriptlistener gave you when changing a gradient?

    Thanks. His script did work but modified all color range and produced weird banding which I didn't like. I'll try the removal of color modification you did!

    Don't mind how empty this is, I was testing having background group, text group and gradient group, while modifying the gradient only once and not once each time one of the group was displayed. 
    Started a new project with a few layer of number text to test out!

     


    Looks like Noise Gradients.
