Javascript Photoshop:用于更改现有文本图层的文本颜色的语法

Javascript Photoshop: Syntax for changing text color of an already existing text layer

本文关键字：文本 图层 颜色 语法 Photoshop 用于 Javascript      更新时间：2023-09-26

我创建了一个 photoshop 动作，将一串白色文本添加到照片中。在这个动作中，我编写了一个脚本来扩展画布大小，并在额外的画布空间内调整文本大小以适应图像的尺寸，从而在照片上创建一个"文本选项卡"。但是，在实现操作和脚本后，选项卡中文本的颜色通常是...不是白色的。

我可以使用什么脚本语法将文本层的颜色更改为白色，以确保它不会随机更改颜色？

作为参考，以下是我的脚本中编辑文本图层的部分：

#target photoshop

var originalRulerUnits = app.preferences.rulerUnits;  
app.preferences.rulerUnits = Units.INCHES; 
var doc = app.activeDocument;  
var layer = doc.activeLayer;  
app.preferences.rulerUnits = Units.PIXELS; 
//create the color for the tab extension
var black = new SolidColor();  
black.rgb.hexValue = "111111";
app.backgroundColor = black;

//*****************************FOR EXTENDING CANVAS AND POSITIONING/RESIZING THE TEXT LAYER*********************************
var orgWidth = doc.width;
var orgHeight = doc.height;
if(orgWidth>orgHeight) //if document is landscape, resize text to fill a smaller portion of the tab
{
    layer.resize(((orgWidth-orgWidth*.2)/(layer.bounds[2]-layer.bounds[0]))*100,(orgWidth*.017/(layer.bounds[3]-layer.bounds[1]))*100,AnchorPosition.TOPLEFT);     
    doc.resizeCanvas(doc.width, (orgHeight + orgWidth*.04), AnchorPosition.TOPCENTER);
    layer.translate(undefined, new UnitValue(0-layer.bounds[1].as('px'),'px'));  
    layer.translate(undefined, orgHeight); 
    layer.translate(undefined, (orgWidth*.02-((layer.bounds[3]-layer.bounds[1])/2.3)));    

}
else //otherwise, resize text to fill a larger portion of the tab
{
    layer.resize(((orgWidth-orgWidth*.05)/(layer.bounds[2]-layer.bounds[0]))*100,(orgWidth*.017/(layer.bounds[3]-layer.bounds[1]))*100,AnchorPosition.TOPLEFT); 
    doc.resizeCanvas(doc.width, (orgHeight + orgWidth*.04), AnchorPosition.TOPCENTER);
    layer.translate(undefined, new UnitValue(0-layer.bounds[1].as('px'),'px'));  
    layer.translate(undefined, orgHeight); 
    layer.translate(undefined, (orgWidth*.02-((layer.bounds[3]-layer.bounds[1])/2.3))); 

}

var layerWidth = Number(layer.bounds[2] - layer.bounds[0]);
var dX = (orgWidth - layerWidth) / 2 - Number(layer.bounds[0]);
layer.translate(dX, undefined);

doc.flatten(); //flatten the text into the photo
app.preferences.rulerUnits = originalRulerUnits;

对文本添加进行编码可能更容易。这是我为这样的场合写的一个方便的功能。文本是对齐的居中，但您可以进行调整。（我会包含该部分功能，但它看起来像 IF 意大利面条）

var x = (app.activeDocument.width.value)/2;
var y = (app.activeDocument.height.value)/2;
createText("Arial-BoldMT", 10.0, 255,255,255, "Gwen Stefanni is bananas", x, y)

// function CREATE TEXT(typeface, size, R, G, B, text content, text X pos, text Y pos)
// --------------------------------------------------------
function createText(fface, size, colR, colG, colB, content, tX, tY)
{
  // Add a new layer in the new document
  var artLayerRef = app.activeDocument.artLayers.add()
  // Specify that the layer is a text layer
  artLayerRef.kind = LayerKind.TEXT
  //This section defines the color of the hello world text
  textColor = new SolidColor();
  textColor.rgb.red = colR;
  textColor.rgb.green = colG;
  textColor.rgb.blue = colB;
  //Get a reference to the text item so that we can add the text and format it a bit
  textItemRef = artLayerRef.textItem
  textItemRef.font = fface;
  textItemRef.contents = content;
  textItemRef.color = textColor;
  textItemRef.size = size
  textItemRef.position = new Array(tX, tY) //pixels from the left, pixels from the top
  var just = Justification.CENTER;
  activeDocument.activeLayer.textItem.justification = just;
}
