Building RGB values from the layer name?

Hello all,

I've been working on this script and I am stuck. I'm not getting an error, but I don't get the results I'm hoping for.

The objective:

Name the active layer with an RGB value, tell Photoshop to replace the active layer with a new solid fill layer, built with the active layer RGB numbers. Any help is greatly appreciated. ~ Joe D

This is my script at this point:

#target photoshop
//sets global variables for active doc and layer
var doc = app.activeDocument;
var lyr = doc.activeLayer;
var lyrName = lyr.name;
// Check the layer name for eleven chracters or less
if (lyrName.length <= 11) {
  var lyrColor = new RGBColor()
  lyrColor.RGB = lyrName;
  pasteLayernameToRGBField(lyrColor);
} else {
  alert("Name the layer with RGB mix (xxx,xxx,xxx)- include commas");
}
function pasteLayernameToRGBField(color) {
  var desc1 = new ActionDescriptor();
  var ref1 = new ActionReference();
  ref1.putEnumerated( stringIDToTypeID( "contentLayer" ), charIDToTypeID( "Ordn" ), charIDToTypeID( "Trgt" ) );
  desc1.putReference( charIDToTypeID( "null" ), ref1 );
  var desc2 = new ActionDescriptor();
  var desc3 = new ActionDescriptor();
  desc3.putString( charIDToTypeID( "Rd  " ), color.red );
  desc3.putString( charIDToTypeID( "Grn " ), color.green );
  desc3.putString( charIDToTypeID( "Bl  " ), color.blue );
  desc2.putObject( charIDToTypeID( "Clr " ), charIDToTypeID( "RGBC" ), desc3 );
  desc1.putObject( charIDToTypeID( "T   " ), stringIDToTypeID( "solidColorLayer" ), desc2 );
  executeAction( charIDToTypeID( "setd" ), desc1, DialogModes.NO );
}

Oh, if that layer is already a solid fill layer, try this:

#target photoshop
var doc = activeDocument;
var lay = doc.activeLayer;
var layNum = new Array()
var run = true;
checkNum (lay.name.split(','))
if(run){
    changeColor ()
    }
function checkNum(numbs){
        for (var i=0;i<numbs.length;i++){
        try{layNum = Number(numbs)
            if(layNum>255||layNum<0|| isNaN ( layNum)){throw(e)}
            }
        catch(e){
            if(i==0){alert(numbs + ' is not a valid red value number')}
            if(i==1){alert(numbs + ' is not a valid green value number')}
            if(i==2){alert(numbs + ' is not a valid blue value number')}
            run = false;
            }
        }
    }
function changeColor(){
    var idsetd = charIDToTypeID( "setd" );
        var desc5 = new ActionDescriptor();
        var idnull = charIDToTypeID( "null" );
            var ref2 = new ActionReference();
            var idcontentLayer = stringIDToTypeID( "contentLayer" );
            var idOrdn = charIDToTypeID( "Ordn" );
            var idTrgt = charIDToTypeID( "Trgt" );
            ref2.putEnumerated( idcontentLayer, idOrdn, idTrgt );
        desc5.putReference( idnull, ref2 );
        var idT = charIDToTypeID( "T   " );
            var desc6 = new ActionDescriptor();
            var idClr = charIDToTypeID( "Clr " );
                var desc7 = new ActionDescriptor();
                var idRd = charIDToTypeID( "Rd  " );
                desc7.putDouble( idRd, layNum[0] );
                var idGrn = charIDToTypeID( "Grn " );
                desc7.putDouble( idGrn, layNum[1] );
                var idBl = charIDToTypeID( "Bl  " );
                desc7.putDouble( idBl, layNum[2] );
            var idRGBC = charIDToTypeID( "RGBC" );
            desc6.putObject( idClr, idRGBC, desc7 );
        var idsolidColorLayer = stringIDToTypeID( "solidColorLayer" );
        desc5.putObject( idT, idsolidColorLayer, desc6 );
    executeAction( idsetd, desc5, DialogModes.NO );

In my updated script, I converted the layer name to a solid color, but you can just split the layer name and use the values in the function and get the same result.

Thanks for being there Chuck, that is the nugget I need.

    For a bit more security and flexibility

    // Check the layer name for eleven chracters or less    
    var val = lyrName.replace(" ","").split(",");
    if (val[0].match(/^\d{3}$/) != null && val[1].match(/^\d{3}$/) != null && val[2].match(/^\d{3}$/) != null) {
      var lyrColor = new SolidColor();
      lyrColor.rgb.red = val[0];    
      lyrColor.rgb.green = val[1];    
      lyrColor.rgb.blue = val[2];    
      pasteLayernameToRGBField(lyrColor);    
    } else {    
      alert("Name the layer with RGB mix (xxx,xxx,xxx)- include commas");    
    }   

    Have fun

    pixel schubser - thanks for your version.

    As I have been working with both the solutions I received, I realize that I was not clear with my initial post. Have a look at the code I posted below. This is my working version for HEX values, It is what I am hoping to accomplish with RGB values. What do you guys think?

    Thanks for all your help.

    /* HEX_layernameMakesColor.js makes the solid fill layer the hex color indicated in the layer name.*/
    #target photoshop
    //sets global variables for active doc and layer
    var doc = app.activeDocument;
    var lyr = doc.activeLayer;
    var lyrName = lyr.name;
    // Check the layer name for six characters and a # symbol at the front
    if (lyrName.length == 6) {
      var lyrcolor = new RGBColor()
      lyrcolor.hexValue = lyrName;
      pasteLayernameToHexField(lyrcolor);
    } else {
      alert("Name the layer with six characters, no # sign.");
    }
    function pasteLayernameToHexField(color) {
      var desc1 = new ActionDescriptor();
      var ref1 = new ActionReference();
      ref1.putEnumerated( stringIDToTypeID( "contentLayer" ), charIDToTypeID( "Ordn" ), charIDToTypeID( "Trgt" ) );
      desc1.putReference( charIDToTypeID( "null" ), ref1 );
      var desc2 = new ActionDescriptor();
      var desc3 = new ActionDescriptor();
      desc3.putDouble( charIDToTypeID( "Rd  " ), color.red );
      desc3.putDouble( charIDToTypeID( "Grn " ), color.green );
      desc3.putDouble( charIDToTypeID( "Bl  " ), color.blue );
      desc2.putObject( charIDToTypeID( "Clr " ), charIDToTypeID( "RGBC" ), desc3 );
      desc1.putObject( charIDToTypeID( "T  " ), stringIDToTypeID( "solidColorLayer" ), desc2 );
      executeAction( charIDToTypeID( "setd" ), desc1, DialogModes.NO );
    }
