Correct answer r-bin

thanks,I desperately need this knowledge of ActionManager


var param = get_brush_param();
// examples
alert(param.opacity, "Opacity");
alert(param.diameter, "Diameter");
// show all (almost all) brush props
alert(obj_to_str(param), "Brush options");
function obj_to_str(obj){var str = ""; for (var p in obj) if(obj.hasOwnProperty(p))try{str+=p+"::"+obj
+"\n";}catch(e){};return str;}

Here you are looking for the current brush tool features.   This is not straight forward for there as so many brush types.   Brush features vary between brush type.  A round brush, a sample tipped brush,  special brush like a fan tip brush.   Different features are supported or not supported.   For example all brushes do not support Hardness/softness.

In the Photoshop Scripting forum there are many scripting sample that gets at some brush types current features.  I have not seem a generalized brush script that well retrieve the features of the current brush no matter what kind of brush is current. I also only hack at scripting I do not know JavaScript and Adobe DOM does not cover all of Photoshop feature.  Often Action Manager code must be user in a Photoshop scripts to do some things.  Here is a JavaScript function to set a round brush tip brush tip feature,  The function first uses Action Manager code to retrieve the current round tip brush's features in case a setting has not been pass to the function. The last thing the function  does is set the setting passed to the function by the coder.

function setBrushFeatures (Diameter,Hardness,Angle,Roundness,Spacing,Flipy,Flipx) {

    //A Brush tool must be the current tool

    if (!app.toolSupportsBrushes(app.currentTool)) selectBrush();  //CC 2014 test if the current tool is a brush type tool else select the brusg tool

    var ref = new ActionReference();

    ref.putEnumerated( charIDToTypeID("capp"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") );

    var appDesc = executeActionGet(ref);

    var toolDesc = appDesc.getObjectValue(stringIDToTypeID('currentToolOptions'));

    var brushDesc = toolDesc.getObjectValue(stringIDToTypeID('brush'));

    if (Diameter == undefined || Diameter == null) Diameter = brushDesc.getDouble(stringIDToTypeID('diameter'));

    if (Hardness == undefined || Hardness == null) Hardness = brushDesc.getDouble(stringIDToTypeID('hardness'));

    if (Angle == undefined || Angle == null ) Angle = brushDesc.getDouble(stringIDToTypeID('angle'));

    if (Roundness  == undefined || Roundness  == null) Roundness = brushDesc.getDouble(stringIDToTypeID('roundness'));

    if (Spacing == undefined || Spacing == null ) Spacing = brushDesc.getDouble(stringIDToTypeID('spacing')); 

    if (Flipy == undefined || Flipy == null ) Flipy = brushDesc.getBoolean(stringIDToTypeID('flipY')); 

    if ( Flipx == undefined || Flipx == null ) Flipx = brushDesc.getBoolean(stringIDToTypeID('flipX'));

    var desc = new ActionDescriptor();

    var ref = new ActionReference();

    ref.putEnumerated( charIDToTypeID( "Brsh" ), charIDToTypeID( "Ordn" ), charIDToTypeID( "Trgt" ) );

    desc.putReference( charIDToTypeID( "null" ), ref );

    var desc1 = new ActionDescriptor();

    desc1.putDouble(stringIDToTypeID('diameter'), Diameter);

    desc1.putDouble(stringIDToTypeID('hardness'), Hardness);

    desc1.putDouble(stringIDToTypeID('angle'), Angle);

    desc1.putDouble(stringIDToTypeID('roundness'), Roundness);

    desc1.putUnitDouble( stringIDToTypeID('spacing'), charIDToTypeID('#Prc'), Spacing);

    desc1.putBoolean(stringIDToTypeID('flipY'), Flipy);

    desc1.putBoolean(stringIDToTypeID('flipX'), Flipx);

    desc.putObject( stringIDToTypeID('to'), charIDToTypeID( "Brsh" ), desc1 );

    executeAction( charIDToTypeID( "setd" ), desc, DialogModes.NO ); 

}

Thanks for your answer that It's just what I need， I need not only brush but all  properties of tools, in addition, I need to “get “”rather than “put”, it's a succuss cases that i try to get the diameter of brush,the script as follow:

     var ref = new ActionReference();

    ref.putEnumerated( charIDToTypeID("capp"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") );

    var appDesc = executeActionGet(ref);

    var toolDesc = appDesc.getObjectValue(stringIDToTypeID('currentToolOptions'));

    var brushDesc = toolDesc.getObjectValue(stringIDToTypeID('brush'));

    var   Diameter = brushDesc.getDouble(stringIDToTypeID('diameter'));

    alert(Diameter);

but i have a question that  i try to get property of Opacity( or Flow or Smoothing) is fail.how  do i get it ?

you are powerful !  where  is the  datasheet about the properties ? i don't know which words can be used for stringIDToTypeID？


What will the knowledge of strinIDs give you? You still need to know how to use these IDs. By and large, these IDs should be described in the SDK documentation, or in the documentation to, for example, a plugin that supports recording in Actions.

In the above function, StringIDs are obtained using the typeIDToStringID() function.
I note that in addition to the name (or ID) of the parameter, you still need to know its type in order to correctly read the data from the descriptor.

You can find and adjust the tool properties in the Options bar control panel. But I see in the picture that you already found it. So what exactly is your question?

    Thanks for your reply. i want to get the property of Tools via script such as the artlayer (app.activeDocument.activeArtlayer.fillOpacity)

    Hi

    Perhaps you should try here Photoshop Scripting

    F5 toggles the Brush panels, or you can turn them on via the Window menu
