hmm.

When i run it i get a jpeg.

if you change the extension in line 2 to .png then you certainly get a png.

However I just tryed to open the jpg i made in photoshop and got an error that " an unknown or invalid jpeg marker was found".

Does anybody know what could be causing this?


Hi Dane,

I am using below action code and received the correct output.

////////////////////////////

var dest = Folder.selectDialog("Pick a folder and save the JPEG there."); 

                 if(myFolder == null){exit(0);}

                

                

function test(){ 

     

     

      String.prototype.hexEncode = function(){ 

      //http://stackoverflow.com/questions/21647928/javascript-unicode-string-to-hex 

        var hex = ''; 

        for(var i=0;i<this.length;i++) { 

            hex += ''+this.charCodeAt(i).toString(16); 

        } 

        return hex; 

      }; 

     

     

      function writeFile(fileDestStr, contents){ 

      var newFile = File(fileDestStr); 

      newFile.open('w'); 

      newFile.write(contents); 

      newFile.close();

Hi Magesh

with exportOption.verticalScaling and horizontalScaling it is somehow possible to get a 300ppi jpeg I think?

However i use app.imageCapture rather than app.exportFile. In this command you can give .resolution = 300.

The captureClip Variable below exports then only then active artboard.

var aiApp = app.activeDocument;
var dest = path + ".jpeg";
var fileSpec = new File(dest);
var captureOptions = new ImageCaptureOptions();
captureOptions.resolution = 300;
captureOptions.antiAliasing = true;
var curBoard = aiApp.artboards[aiApp.artboards.getActiveArtboardIndex()]
var captureClip = this.curBoard.artboardRect
aiApp.imageCapture(fileSpec, captureClip,captureOptions)

Maybe this would be a solution for you.
