使用Javascript在Photoshop中编辑文本图层的内容

Question

我正在尝试编写脚本来编辑Photoshop CS6中文本层的内容。 那可能吗？

我有大约2000张图片，需要为一个工作项目处理。 首先，我使用已有的JavaScript在Photoshop中将每个图像的文件名添加为文本层（请参见下文）。 示例文件名是“ UCMC_0018015 D FSH E”。 我的脚本成功将此文件名添加到图像中，作为Photoshop中的文本层。

但是，我然后想编辑文本层，以便用空格替换下划线，并从文本字符串的末尾删除“ FSH E”（所有文件名都有这些元素，但是文件名中的数字会有所不同从文件到文件）。 谁能帮我完成我需要做的脚本？ 我不熟悉编写和运行脚本，但是我正在竭尽全力地学习这份工作。 您能给我的任何建议将不胜感激。

这是我当前用于将文件名添加到图像的脚本。 我不确定是否可以编辑它，或者是否需要编写一个新脚本来编辑文本层。 谢谢您的帮助！

您可以使用正则表达式删除所有空格并将其替换为下划线。 据我了解，您可以先用文字替换“ FSH E”为空字符串。 如果这些字母不同，那么您将不得不使用不同的策略。 但这现在将起作用。 这是您需要的代码的基本部分。

var myFileName = "UCMC_0018015 D FSH E";

// remove " FSH E" 
myFileName = myFileName.replace(" FSH E", "");

// replace whitespce with underscores
myFileName = myFileName.replace(/\s/gi, "_");

alert(myFileName);

您的最终代码应如下所示

//Check if a document is open
if ( documents.length > 0 )
{
var originalRulerUnits = preferences.rulerUnits;
preferences.rulerUnits = Units.PERCENT;

try
{
    var docRef = activeDocument;

    // Create a text layer at the front

    var myLayerRef = docRef.artLayers.add();
    myLayerRef.kind = LayerKind.TEXT;
    myLayerRef.name = "Filename";
    var myTextRef = myLayerRef.textItem;

    //Set your parameters below this line

    //If you wish to show the file extension, change the n to y in the line below, if not use n.
    var ShowExtension = false;
    // Insert any text to appear before the filename, such as your name and copyright info     between the quotes. 
    //If you do not want extra text, delete between the quotes (but leave the quotes in).
    var TextBefore = "";

    // Insert any text to appear after the filename between the quotes. 
    //If you do not want extra text, delete between the quotes (but leave the quotes in).
    var TextAfter = "";

    // Set font size in Points
    myTextRef.size = 30;

    //Set font - use GetFontName.js to get exact name
    myTextRef.font = "Times New Roman";

    //Set text colour in RGB values
    var newColor = new SolidColor();
newColor.rgb.red = 0;
newColor.rgb.green = 0;
newColor.rgb.blue = 0;
myTextRef.color = newColor;

    // Set the position of the text - percentages from left first, then from top.
    myTextRef.position = new Array( 75, 98);

    // Set the Blend Mode of the Text Layer. The name must be in CAPITALS - ie change NORMAL to DIFFERENCE.
    myLayerRef.blendMode = BlendMode.NORMAL;

    // select opacity in percentage
    myLayerRef.opacity = 100;

// The following code strips the extension and writes tha text layer. fname = file name only            

var fname = docRef.name;

// code changes here.
// remove " FSH E" 
fname = fname.replace(" FSH E", "");

// replace whitespaces with underscores
fname = fname.replace(/\s/gi, "_");

//use extension if set
if ( ShowExtension == true )
{
    di =(fname).lastIndexOf(".");      
    fname = (fname).substr(0, di);
}  

    myTextRef.contents = TextBefore + "  " + fname +  "  " + TextAfter;


}
catch( e )
{
    // An error occurred. Restore ruler units, then propagate the error back
    // to the user
    preferences.rulerUnits = originalRulerUnits;
    throw e;
}

// Everything went Ok. Restore ruler units
preferences.rulerUnits = originalRulerUnits;
}
else
{
alert( "You must have a document open to add the filename!" );
}

• 作为您JavasScript的新手，我想指出一下，您具有showextension变量作为字符串。 使其成为布尔值可能会更容易。 因此，它只能是TRUE或FALSE。 一个字符串可能是，好吧...任何东西。
• 另一点是您拥有indexOf来查找扩展名。 这将正常工作。 除非您有一个文件名，例如“ my.lovely.photo.jpg”； 而您的扩展名将是“ lovely.photo.jpg”，您可能会猜到，使用lastIndexOf可以找到字符串结尾附近的项目的索引。
