使用Javascript在Photoshop中编辑文本层的内容

我正在尝试编写一个脚本来编辑PhotoshopCS6中文本层的内容。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javascript在Photoshop中添加每个图像的文件名作为文本层，我已经在下面看到了。示例文件名是UCMC_0018015 D FSH E。我的脚本成功地将此文件名作为Photoshop中的文本层添加到图像中

但是，我想编辑文本层，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，但文件名中的数字因文件而异。有人能帮我写剧本吗？我不熟悉编写和运行脚本，但我正在尽我最大的努力在工作中学习。如果您能给我任何建议，我将不胜感激

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，或者是否需要编写新脚本来编辑文本层。谢谢你的帮助

//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 = "n";
    // 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            

di=(docRef.name).indexOf(".");      
fname = (docRef.name).substr(0, di);
//use extension if set
if ( ShowExtension == "y" )
{
fname = docRef.name
}  


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


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

}

// Everything went Ok. Restore ruler units

您可以使用正则表达式删除所有空白并用下划线替换它们。据我所知，您可以先将FSH E的文本替换为空字符串。如果这些字母不同，那么你就必须使用不同的策略。但这将暂时奏效。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);

您的最终代码应该如下所示

//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JavasScript的新手，我想指出，showextension变量是一个字符串。它可能更容易成为布尔值。所以它只能是真的或假的。一根绳子可以，嗯。。。任何东西 另一点是，您需要indexOf来查找扩展名。好的。除非您有一个文件名，如my.lovely.photo.jpg；而您的扩展名应该是可爱的.photo.jpg，正如您可能猜到的那样，使用lastIndexOf可以在字符串末尾附近找到该项的索引。

试着实现全部功能，告诉我们会发生什么。非常感谢你，食尸鬼傻瓜。我尝试将此代码放到脚本中，但不管文件名如何，它都会给我脚本警报UCMC_0018015_D。我不确定我是否添加了错误的代码，我对javascript非常陌生！很抱歉或者如果访问Photoshop文本层需要额外的编码。有什么想法吗？下面是我的完整脚本，其中添加了您的代码。谢谢你的帮助。哎呀，我没意识到评论中的字符数量有限。我不会重新发布我的脚本，我只会告诉您，我在myLayerRef.opacity=100之后立即将代码按原样插入到我的脚本中；在//之前，下面的代码剥离扩展并写入文本层。fname=仅文件名我已经修改了您的代码，因此它现在可以与文件名一起使用。
