利用Photoshop javascript 给图片添加拍摄日期(creation date)

简单的自动化脚本，方便批量作业。

// This script is used to add creation date for each .jpg// in folder specified as workDir and save it with the same// name in another folder specified as saveDir.var workDir = 'C:/Users/ABC/Pictures/Camera/' var saveDir = 'C:/Users/ABC/Pictures/output/' // Get all .jpg files in folder.var processFolder = Folder(workDir)var fileList = processFolder.getFiles(/\.(jpg)$/i);app.bringToFront();// Loop through filesfor (var i = 0; i < fileList.length; i++) {     // Only process the returned file objects     // The filter 'should' have missed out any folder objects      if (fileList[i] instanceof File && fileList[i].hidden == false) {addCreationDateAndSave(fileList[i], new File(saveDir + fileList[i].name))//$.writeln(fileList[i].name)     }}function addCreationDateAndSave(srcFile, saveFile) {    // Remember current unit settings and then set units to    // the value expected by this script    var originalUnit = preferences.rulerUnits    preferences.rulerUnits = Units.INCHES    var fileRef = srcFile    var docRef = app.open(fileRef)    // Create a new art layer containing text    var artLayerRef = docRef.artLayers.add()    artLayerRef.kind = LayerKind.TEXT    // Set the contents of the text layer.    var textItemRef = artLayerRef.textItem    // Set text color, font and size    textColor = new SolidColor();    textColor.rgb.red = 255    textColor.rgb.green = 255    textColor.rgb.blue = 255    textItemRef.color = textColor    textItemRef.font = "Myriad Pro"    textItemRef.size = new UnitValue(24,  "pt")    // Set position of textItem, pre-estimate the width and    // height of textItem of contents like '2017/03/30' for    // a specified font size.    var tHalfWidth = new UnitValue(0.75, "in")    var tHeight = new UnitValue(0.3, "in")    textItemRef.position = Array(app.activeDocument.width.as("in") * 0.5 -tHalfWidth.as("in"), app.activeDocument.height.as("in") * 0.98 -tHeight.as("in"))    // creationDate example: 20170413    var Y = docRef.info.creationDate.substring(0,4)    var M = docRef.info.creationDate.substring(4,6)    var D = docRef.info.creationDate.substring(6)    textItemRef.contents = Y + "/" + M + "/" + D    jpgSaveOptions = new JPEGSaveOptions()    jpgSaveOptions.embedColorProfile = true    jpgSaveOptions.formatOptions = FormatOptions.STANDARDBASELINE    jpgSaveOptions.matte = MatteType.NONE    jpgSaveOptions.quality = 12    app.activeDocument.saveAs(saveFile, jpgSaveOptions, true,Extension.LOWERCASE)    app.activeDocument.close(SaveOptions.DONOTSAVECHANGES)    // Restore original ruler unit setting    app.preferences.rulerUnits = originalUnit    // Release references    docRef = null    artLayerRef = null    textItemRef = null}
