I don't know how to accomplish this (or even if it is possible) using only an Action. Extendscript is compatible with both PC and Mac. There are occasional differences in behavior, but for something relatively simple like this I would expect it to work fine on both platforms. Is the concern that the designers are already familiar with installing actions and may have trouble getting up and running with a script? ... View more

You are close! The while loop must be run for each pdf file, so it needs to go into a for loop containing the pdf files. The other filetypes can be handled separetely without the special resolution check. I think the below code accomplishes what you want: #target photoshop var theFolder = Folder.selectDialog("select folder"); if (theFolder) {     //get all of the jpg and tiff files and handle them separately     var theNonPDFFiles = theFolder.getFiles((/\.(jpg|tif)$/i));     for (var fileIdx = 0; fileIdx < theNonPDFFiles.length; fileIdx++) {         app.open(File(theNonPDFFiles[fileIdx]))         }     //get the pdf files to handle with the resolution check     var thePDFFiles = theFolder.getFiles("*.pdf");     app.preferences.rulerUnits = Units.CM; //because you specified your input resolutions in CM     app.displayDialogs = DialogModes.NO;     for (var fileIdx = 0; fileIdx < thePDFFiles.length; fileIdx++) {         var theFile = thePDFFiles[fileIdx];         var pagesRemaining = true;         var page = 1;         //we need to perform our loop over each pdf file         while (pagesRemaining){             try {                 // define pdfopenoptions;                 var pdfOpenOpts = new PDFOpenOptions;                 pdfOpenOpts.antiAlias = true;                 pdfOpenOpts.bitsPerChannel = BitsPerChannelType.EIGHT;                 pdfOpenOpts.cropPage = CropToType.CROPBOX;                 pdfOpenOpts.mode = OpenDocumentMode.CMYK;                 pdfOpenOpts.resolution = 1;                 pdfOpenOpts.bitsPerChannel = BitsPerChannelType.EIGHT;                 pdfOpenOpts.usePageNumber  = true;                 pdfOpenOpts.page = page;                 //open once without a resolution specified                 var thePage = app.open(theFile, pdfOpenOpts);                 //get the size of the page                 var thePageWidth = thePage.width;                 var thePageHeight = thePage.height;                 //close once you have the necessary info                 thePage.close(SaveOptions.DONOTSAVECHANGES);                 //determine the desired resolution                 var testres = thePageWidth * thePageHeight;                 var res = "";                 if (testres <= 20000) {                       var res = 150;                     }                 else if (testres > 20000 && testres <= 50000) {                         var res = 100;                         }                 else if (testres > 50000 && testres <= 150000) {                         var res = 72;                         }                 else if (testres > 150000 && testres <= 300000) {                         var res = 60;                         }                 else if (testres > 300000 && testres <= 450000) {                         var res = 50;                         }                 else if (testres > 450000 && testres <= 600000) {                         var res = 40;                         }                 else { //(testres > 600000 )                         var res = 30;                         }                 pdfOpenOpts.resolution = res;                 //reopen with the correct resolution                 var thePage = app.open(theFile, pdfOpenOpts);                 page++;                 }               catch (e) {                   pagesRemaining =  false //no pages remain                   };           };         }     } ...

I didn't change the content of the code you pasted (only changed the formatting to make it easier to read ) so it makes sense that it still wouldn't work. If you were to more clearly state what it is you are trying to accomplish, someone here might be able to help, I just wasn't sure what exactly the goal was. When it comes to pasting code into the forum, if you paste it in as plain text and then click the "Use advanced editor" link, followed by ">>", and choose Syntax Highlighting for Javascript, it will look as mine does. ...

Is the goal to apply a (different) random opacity and rescale to each layer? I cleaned up the formatting of the code you pasted to make it easier to see what was going on: #target photoshop var aDoc = app.activeDocument; var aSel = aDoc.selection; var opMin = Number(prompt("min (0-1000%)", 0)); var opMax = Number(prompt("max (0-1000%)", 200)); if(opMin > opMax){     temp = opMin;     opMin = opMax;     opMax = temp;     } if(opMin<0){     opMIn = 0;     } if(opMax>1000){     opMax = 1000;     } for(i=0; i<nSel; i++){     var resScale = Math.floor(Math.random() * (opMax - opMin + 1)) + opMin;     aSel.resize(resScale, resScale); } If my interpretation about what you are trying to do is correct, in line 4 you will want to use the aDoc.artLayers or aDoc.layerSets collections to grab the layers to loop through. Another issue is in line 23 in which nSel is used (without having been declared). Presumably you would want to set this to the total number of layers you want to loop through. The other confusing portion is line 24 in which opMin and opMax (the min and max for the desired opacity ranges?) are used to calculate the rescale factor. Should the rescaling depend on the opacity? Hopefully this can get you started down the path to what you want to accomplish. ... View more

The following method will allow you to move the time indicator to a specific place, but I couldn't figure out how (via script or the GUI) to grab the timestamp of a particular key frame. If you know how to do that it should be easy to then use the method below for the purpose you described (I don't know if PS provides that functionality or not). As r-bin mentioned, if you provided a sample .psd file it might help. #target photoshop setTimelineTime(2, 25, 30); function setTimelineTime(seconds, frame, frameRate) {     var timelineReference = new ActionReference();     timelineReference.putProperty( s2t( "property" ), s2t( "time" ));     timelineReference.putClass( s2t( "timeline" ));        var timeDescriptor = new ActionDescriptor();     timeDescriptor.putInteger( s2t( "seconds" ), seconds );     timeDescriptor.putInteger( s2t( "frame" ), frame );     timeDescriptor.putDouble( s2t( "frameRate" ), frameRate );        var timelineDescriptor = new ActionDescriptor();     timelineDescriptor.putReference( c2t( "null" ), timelineReference );     timelineDescriptor.putObject( s2t( "to" ), s2t( "timecode" ), timeDescriptor );     executeAction( s2t( "set" ), timelineDescriptor, DialogModes.NO );     } function c2t (c) {     return app.charIDToTypeID(c);     } function s2t (s) {     return app.stringIDToTypeID(s);     } ...

Yes, this is possible in Photoshop. As far as I can tell, ExtendScript treats an ArtBoard like a regular LayerSet. Do you have an Illustrator Script you are working with as a starting point? ... View more

I think SuperMerlin​'s approach of writing the system command result to a text file might be the way to go. If you just want the computer name though instead of all the environment variables you could use "scutil --get ComputerName" (in OSX).

Do you mean the text layers containing the usernames are in layer groups like this?   To handle this you will first need to use the layerSets object before getting the specific layers. See below: #target photoshop var files = app.openDialog("Please select the relevant files"); var newTwitter = prompt("Type the new Twitter handle:"); var newInstagram = prompt("Type the new Instagram handle:"); for(var i = 0; i < files.length; i++) { var file = new File(files[i]); var docRef = app.open(file); var twitterGroup = docRef.layerSets.getByName("twitterWrapper"); var twitterLayer = twitterGroup.artLayers.getByName("twitterHandle"); twitterLayer.textItem.contents = newTwitter; var instagramGroup = docRef.layerSets.getByName("instagramWrapper"); var instagramLayer = instagramGroup.artLayers.getByName("instagramHandle"); instagramLayer.textItem.contents = newInstagram; docRef.close(SaveOptions.SAVECHANGES) }   No need to pay me. Pay it forward somehow 🙂 ... View more

While both of the above answers are correct, I prefer the following method as it is slightly more succinct: function makeTwoCharString(intIn){          return ("0" + intIn.toString()).slice(-2);         } As long as the input is between 0 and 99 (inclusive) it will return the desired two digit string. Combining with your code gives: alert(runTime()); function runTime () {   try{     var digital = new Date();     var hours = makeTwoCharString(digital.getHours());     var minutes = makeTwoCharString(digital.getMinutes());     var seconds = makeTwoCharString(digital.getSeconds());     militaryTime = hours + ":" + minutes + ":" + seconds;      return militaryTime;     } catch(e) {alert(e)} } ...

Oh so you were able to run the script, and now you are asking why you might use something like this? The primary use for log files is to help with things like monitoring, troubleshooting and debugging of your program. This post (programming practices - Logging: Why and What? - Software Engineering Stack Exchange ) provides some more detailed answers as to why logging is useful for software programs. To give a simple Photoshop example, imagine your script is processing a batch of images and rescaling them for use on the web. One thing you might want to use logging for is to record a warning every time the input image is below a certain size threshold. This would enable you to look at the log after the fact and see which images might not be of high enough resolution. Does that clarify things? (Also -- I don't think this was your question, but if you were asking how to open/view the log files, just open with a text editor) ... View more

I think your issue is that $.evalFile() takes a File object as its input while you are inputting a path to the file as a String. Try creating a File first and then using that as the input: var batchMergeFile = new File("C:\Program Files\Adobe\Adobe Photoshop CC 2018\Presets\Scripts\batchmerge.jsx"); $.evalFile(batchMergeFile); Hopefully that helps! ...

If you go to the GitHub repository I linked you will find both the library file ("logging.jsxlib") and a script showing an example of how to use it ("main.jsx"). You can download a copy of the whole repo as a zip file using this link: https://github.com/sidpalas/extendscript-logging/archive/master.zip Then simply run main.jsx (either from Photoshop or using ExtendScript Toolkit) and it should generate 3 log files as described. One thing to point out is the relative path I used within main.jsx of "./logging.jsxlib". The two files need to be in the same directory for that include statement to work properly. Hopefully that helps! ... View more

I can't speak for SuperMerlin​, but usually when you see code using ActionDescriptors being utilized with executeAction(), it is the result of using the ScriptingListener plugin (see here). The plugin records actions taken within photoshop as ExtendScript code in a log file. This allows you to manually execute a particular sequence and then view the resulting code. While incredibly useful, the code it produces is not the cleanest and if the desired functionality is available via the ExtendScript API it is preferable to use those functions. The ScriptingListener code can then be used directly, used as an example but modified by hand to acheive the desired result, or processed programmatically to clean it up (using an approach such asClean SL). Additional Adobe documentation on Action Manager can be found in the Photoshop CC Scripting Guide starting on page 73. Hopefully this helps! ... View more

As Loic.Aigon​ implied, this is less of a Photoshop Scripting question and more of a general Javascript question. There are multiple ways to accomplish something similar to what you describe and without knowing your specific use case it is difficult to recommend the best approach. In general, you want to keep variables to the minimum scope possible while still accomplishing the task at hand. This helps prevent cases where global variables are edited in multiple places throughout a program which can lead to nasty bugs that are hard to track down. With that warning in place, if you still want to use a global variable, this is how you would do it: var globalVar  = 10; //Defined outside the function so it becomes global $.writeln(globalVar); //You could use alert() here if you aren't using ExtendScript ToolKit testFunction(); //Call the function $.writeln(globalVar); function testFunction() {     globalVar = 5; //Do not use the "var" keyword or it will declare a local variable with the same name } A better option may be to have the function return the variable you want to use elsewhere. For example: var outsideVar = testFunctionWithReturn(); $.writeln(outsideVar); function testFunctionWithReturn() {     var localVar = 15;     return localVar; } ... View more

It seems that this Stack Overflow post​ is close to what OP wanted, except that per the Javascript Tools Guide "Adobe Photoshop does not support script creation of palette windows" If you change the type of window to be a "dialog" instead of a "palette", the window does show up, but then I think it stops the execution of the delay function and causes PS to freeze (at least when I tested it...). ...

You mentioned being able to: ...get it to the point where it will merge the whole group to a layer and rename that, but that won't work for the application I'm trying to accommodate...

It seems to be caused by the "Auto-nesting" of layers within Artboards. By selecting the option shown in the screenshot ("Prevent auto-nesting into and out of Artboards"), I was then able to delete the TEMP LayerSet without the odd behavior described in my previous response. I was even able to duplicate the LayerSet into the desired location, eliminating a line: var docRef = app.activeDocument; var artboard1 = docRef.layerSets.getByName("Artboard 1"); var warningLayerSet = artboard1.layerSets.getByName("WARNING"); var targetLayerSet = docRef.layerSets.getByName("TARGET"); var tempLayerSet = targetLayerSet.layerSets.add(); tempLayerSet.name = "TEMP"; var warningLayerSetDuplicate = warningLayerSet.duplicate(tempLayerSet, ElementPlacement.PLACEBEFORE); tempLayerSet.remove(); If toggling this feature doesn't mess up your workflow, perhaps that will do the trick! ...
