Want to run batch process on TIFFs only

[ki.kennedy]

I have many folders that contain both TIFF and PDF files.  I would like to run a process to save the TIFFs with LZW compression.  However, I don't want to touch the PDFs.  I have tried using a Batch process and the built-in Image Processor tool, but haven't been able to find a way to limit the process to TIFFs only.  Does anyone have any tips?  Thanks so much!

Have you tried filtering to display only TIFFs in Bridge then Tools > PS > Image Processor on your selected images?

Jane

Hi Jane! Thanks for your response. I gave that a try and I filtered by file type in Bridge but when I go to Image Processor in Photoshop, I don't see an option to process files from Bridge only.

[jane-e]

Hi ki.,

Are the images selected in Bridge? If you have filtered to TIFF, Cmd+A (Ctrl+A on Windows) should do it.

Thanks! I have done that, but it still doesn't seem like Bridge and Photoshop are talking to each other. Is there something in the settings of either program I need to change?

From within Bridge, running Image Processor should show the number of selected files by default:

Using the optional Image Processor Pro script, one can first select the files in Bridge, then go to Photoshop and run IPP and select the option for selected files in Bridge:

Thanks again! I think the issue is that in Bridge, Photoshop is not showing up in the Tools dropdown for me. Do you know why that might be?

Are your versions of Bridge and Photoshop in step e.g. both the latest versions?

Dave

[ki.kennedy]

Hi Dave! Yes, both are on the latest versions. Thanks!

Hi

If you have more than one version installed, an older version of Bridge may have opened. Can you look at the version number for both? It's in the Application menu > About on a Mac and Help > About on Windows. You might also open directly from the Creative Cloud app.

[ki.kennedy]

Yes, I have opened Bridge from the Creative Cloud app. It's on Version 9.1.0.338. Photoshop is on version 20.0.6.

Here is a script that I have adapted to batch save an input folder of mixed files and only process .TIF files with LZW compression:

#target photoshop
//forums.adobe.com/message/10491208
//forums.adobe.com/message/10487873#10487873
var tifFolder = Folder.selectDialog("Select the folder containing TIFFs", "");  
var myFiles = tifFolder.getFiles(/\.(tif)$/i);  
  
//jongware.mit.edu/pscs5js_html/psjscs5/pc_TiffSaveOptions.html
//jongware.mit.edu/pscs5js_html/psjscs5/pe_TIFFEncoding.html
// TIFFEncoding.NONE
// TIFFEncoding.JPEG
// TIFFEncoding.TIFFLZW
// TIFFEncoding.TIFFZIP
var so = new TiffSaveOptions();  
so.imageCompression = TIFFEncoding.TIFFLZW;  
  
for (var a = 0; a < myFiles.length; a++){  
    var d = open(myFiles[a]);  
    d.saveAs(new File(d.fullName), so);  
    d.close();  
};

Hi Stephen, Thank you so much! I followed the directions on your blog- I wasn't sure whether this was meant to run from Photoshop or Bridge, so I tried with both programs, but both times I got an error. I'm not sure how to attach a screenshot on this messageboard, but in Photoshop, the message that came up said "Error 8: Syntax error Line:1"

[Stephen Marsh]

What program did you paste the copied code into? I'm guessing it was not saved as a plain text document as mentioned in my blog, perhaps saved as a rich text document. That is the error I get when running the code if I save as say RTF and not TXT before renaming to JSX.

Can you post a screenshot of the code in your text editor? Here is a screenshot:

Sorry, for not making it clear, this script is for Photoshop:

#target photoshop

[ki.kennedy]

Hi Stephen, Thank you so much, yes, I didn't realize the text editor I was using was saving as RTF first, so I used Sublime Text instread to save directly to jsx and now it's working great! I just have one quick additional question- is it possible to modify the script to so it will look for TIFFs several layers deep in the folder structure?

[Stephen Marsh]

Yes, it is possible, I’ll make a new post with a different script...

"I filtered by file type in Bridge but when I go to Image Processor in Photoshop..."

Hi

I was reading through everything a second time and spotted the way this was worded. Don't go into Image Processor from PS (if you are). Do it from Bridge with Bridge > Tools > PS > Image Processor and PS will launch automatically and will process the files that are selected in Bridge. Can your confirm your steps?

Jane

[ki.kennedy]

Hi Jane,

[ki.kennedy]

Yes, I am in Bridge with the files selected and then I'm going to the Tools dropdown within Bridge, but I don't see PS or Photoshop as an option in that dropdown.

Here is a new version of the script that I previously posted to batch save .TIF files with LZW compression. This version will additionally process .tif files found in all sub-folders under the top-level input folder.

#target photoshop

// Want to run batch process on TIFFs only

// Special thanks to Paul MR for the recursive folder processing code!
// photoshopgurus.com/forum/threads/batch-and-subfolders.22134/
// batch and subfolders

alert('This script will resave all TIFF files with LZW compression. All sub-folders under the selected input folder will be processed.');

var imageFolder = Folder.selectDialog('Select the top-level folder with TIFF files to process');

var origDialogs = app.displayDialogs;
app.displayDialogs = DialogModes.NO;

// Script Execution Timer - Function    
var timeDiff = {
    setStartTime: function() {
        d = new Date();
        time = d.getTime();
    },
    getDiff: function() {
        d = new Date();
        t = d.getTime() - time;
        time = d.getTime();
        return t;
    }
};

// Script Execution Timer - Start    
timeDiff.setStartTime();

if (imageFolder != null) processFolder(imageFolder);

function processFolder(folder) {
    var fileList = folder.getFiles()
    for (var i = 0; i < fileList.length; i++) {
        var file = fileList[i];
        if (file instanceof File && file.name.match(/\.tif/i)) {
            open(file);

// Start Main Code Block
            var saveOpt = new TiffSaveOptions();
            saveOpt.imageCompression = TIFFEncoding.TIFFLZW;
            var aDoc = app.activeDocument;
            aDoc.saveAs(new File(aDoc.fullName), saveOpt);
            aDoc.close(SaveOptions.SAVECHANGES);
// End Main Code Block

        } else
        if (file instanceof Folder) {
            processFolder(file);
        }
    }
}

app.displayDialogs = origDialogs;

// Script Execution Timer - Finish    
alert('Batch LZW save completed! ' + '\r' + '(' + timeDiff.getDiff() / 1000 + ' seconds)');

// To Do: It would be nice to add a report on the number of files processed...

Stephen, you might want to check the color profile of the tifs that you save that way. I had a friend who just had me test a similar script, and it stripped out the color profile. You might have to use AM code.

[Stephen Marsh]

Thanks Chuck, yes, my test files had the same profile as my working space and did not throw a warning that messed up the batch. I have updated the code to turn off dialogs. The source ICC profile is retained when resaving with LZW in my tests.

[ki.kennedy]

Thank you so much- this works great for me!  And sorry for the delay in my response, I was out of the office last week.

Thank you, thank you, thank you

I was getting so despondent to find a solution to this exact problem.

You are a legend!!!!!!!!!!!!!!!
