Extracting Multiple Text Font Color

mycort · Post by **mycort** » Thu Sep 27, 2012 5:37 pm

My Friend is trying extract multiple font colors from a single text line and he can't seem to make it work:

He's even tried this code but no luck working:
Key 14 = color: DescValueType.OBJECTTYPE

Code Snippet that is not working:
Code: Select all try {
var aColor = "Color: " + styleDesc.getString(stringIDToTypeID('color'));
} catch (e) {
var aColor = '';
};

Full Code:
Code: Select all// get fonts and other parameters used in type layer
function getFonts(textLayer) {

if (textLayer.kind == LayerKind.TEXT) {

app.activeDocument.activeLayer = textLayer;
var ref = new ActionReference();
ref.putEnumerated(charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
var layerDesc = executeActionGet(ref);
var textDesc = layerDesc.getObjectValue(stringIDToTypeID('textKey'));
var rangeList = textDesc.getList(stringIDToTypeID('textStyleRange'));

var fonts = [];

for (var m = 0; m < rangeList.count; m++) {

var styleDesc = rangeList.getObjectValue(m).getObjectValue(stringIDToTypeID('textStyle'));
var aFrom = rangeList.getObjectValue(m).getInteger(stringIDToTypeID('from'));
var aTo = rangeList.getObjectValue(m).getInteger(stringIDToTypeID('to'));
var theLetters = app.activeDocument.activeLayer.textItem.contents.slice(aFrom, aTo);

var aFont = "Font: " + styleDesc.getString(stringIDToTypeID('fontPostScriptName'));

try {
var aSize = "Size: " + styleDesc.getUnitDoubleValue(stringIDToTypeID('size')) + " " + typeIDToCharID(styleDesc.getUnitDoubleType(stringIDToTypeID('size')));
} catch (e) {
var aSize = '';
};

try {
var aColor = "Color: " + styleDesc.getString(stringIDToTypeID('color'));
} catch (e) {
var aColor = '';
};

var merged = false;

for (var x = 0; x < m; x++) {
try {
if (fonts[x].font === aFont && fonts[x].size === aSize && fonts[x].color === aColor) {
fonts[x].text += "\"" + theLetters.replace(/^\s+/, '').replace(/\s+$/, '') + "\"\r";
merged = true;
}
} catch (e) {}
}

if (!merged) {
fonts.push({
text: "\"" + theLetters.replace(/^\s+/, '').replace(/\s+$/, '') + "\"\r",
font: aFont,
size: aSize,
color: aColor
});
}

};

return fonts;

}
};

Please try this...

Code: Select all// get fonts and other parameters used in type layer
function getFonts(textLayer) {

if (textLayer.kind == LayerKind.TEXT) {

app.activeDocument.activeLayer = textLayer;
var ref = new ActionReference();
ref.putEnumerated(charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
var layerDesc = executeActionGet(ref);
var textDesc = layerDesc.getObjectValue(stringIDToTypeID('textKey'));
var rangeList = textDesc.getList(stringIDToTypeID('textStyleRange'));

var fonts = [];

for (var m = 0; m < rangeList.count; m++) {

var styleDesc = rangeList.getObjectValue(m).getObjectValue(stringIDToTypeID('textStyle'));
var aFrom = rangeList.getObjectValue(m).getInteger(stringIDToTypeID('from'));
var aTo = rangeList.getObjectValue(m).getInteger(stringIDToTypeID('to'));
var theLetters = app.activeDocument.activeLayer.textItem.contents.slice(aFrom, aTo);

var aFont = "Font: " + styleDesc.getString(stringIDToTypeID('fontPostScriptName'));

try {
var aSize = "Size: " + styleDesc.getUnitDoubleValue(stringIDToTypeID('size')) + " " + typeIDToCharID(styleDesc.getUnitDoubleType(stringIDToTypeID('size')));
} catch (e) {
var aSize = '';
};

try {
var Colour = new SolidColor;
Colour.rgb.red = styleDesc.getObjectValue(stringIDToTypeID('color')).getUnitDoubleValue(stringIDToTypeID('red'));
Colour.rgb.green = styleDesc.getObjectValue(stringIDToTypeID('color')).getUnitDoubleValue(stringIDToTypeID('grain'));
Colour.rgb.blue = styleDesc.getObjectValue(stringIDToTypeID('color')).getUnitDoubleValue(stringIDToTypeID('blue'));
var aColor = Colour.rgb.hexValue;
} catch (e) {
var aColor = '';
};

var merged = false;

for (var x = 0; x < m; x++) {
try {
if (fonts[x].font === aFont && fonts[x].size === aSize && fonts[x].color === aColor) {
fonts[x].text += "\"" + theLetters.replace(/^\s+/, '').replace(/\s+$/, '') + "\"\r";
merged = true;
}
} catch (e) {}
}

if (!merged) {
fonts.push({
text: "\"" + theLetters.replace(/^\s+/, '').replace(/\s+$/, '') + "\"\r",
font: aFont,
size: aSize,
color: aColor
});
}

};

return fonts;

}
};

Another way to extract a SolidColor object from a color descriptor:
Code: Select allvar ref = new ActionReference();
ref.putEnumerated( charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") );
var desc = executeActionGet(ref).getObjectValue(charIDToTypeID("Txt ")).getList(charIDToTypeID("Txtt")).getObjectValue(0).getObjectValue(charIDToTypeID("TxtS"));

// desc is an ActionDescriptor that contain the "Clr " key
// works with any color mode that supports text layers
var firstRangeColor = getColorFromDescriptor( desc.getObjectValue(charIDToTypeID("Clr ")), typeIDToCharID(desc.getClass(charIDToTypeID("Clr "))));
alert('The RGB.hexValue of the first text range is: '+firstRangeColor.rgb.hexValue);

function getColorFromDescriptor( colorDesc, keyClass ){
var colorObject = new SolidColor();
switch( keyClass ){
   case "Grsc":
      colorObject.grey.grey = color.getDouble(charIDToTypeID('Gry '));
      break;
   case "RGBC":
      colorObject.rgb.red = colorDesc.getDouble(charIDToTypeID('Rd '));
      colorObject.rgb.green = colorDesc.getDouble(charIDToTypeID('Grn '));
      colorObject.rgb.blue = colorDesc.getDouble(charIDToTypeID('Bl '));
      break;
   case "CMYC":
      colorObject.cmyk.cyan = colorDesc.getDouble(charIDToTypeID('Cyn '));
      colorObject.cmyk.magenta = colorDesc.getDouble(charIDToTypeID('Mgnt'));
      colorObject.cmyk.yellow = colorDesc.getDouble(charIDToTypeID('Ylw '));
      colorObject.cmyk.black = colorDesc.getDouble(charIDToTypeID('Blck'));
      break;
   case "LbCl":
      colorObject.lab.l = colorDesc.getDouble(charIDToTypeID('Lmnc'));
      colorObject.lab.a = colorDesc.getDouble(charIDToTypeID('A '));
      colorObject.lab.b = colorDesc.getDouble(charIDToTypeID('B '));
      break;
   default: return null;
}
return colorObject;
}

Note that the keys in a color descriptor will be different depending on with color mode the document is in. You can't count on it having a fixed number of keys nor the IDs of the keys.
