Find Layered TIFF Files

  • October 28, 2015

Is there a way to find layered TIFF files in Bridge (or another method, perhaps scripting Bridge/Photoshop)?

This came up on another forum, where layered TIFF files may be accidentally saved when they should be layered PSD for this workflow.

The best that I have been able to do is use the Bridge FIND command to search all metadata excluding the keyword “Adobe Photoshop Camera Raw” as it appears that in CS6, a flat TIFF contains this phrase in XMP metadata, while a layered TIFF does not. Text layers can be found using the metadata keyword “layers”, however this does not find pixel or adjustment layers.

There are alternative options with ExifTool or ImageMagick/GraphicsMagick, however I was looking for a “standard” Adobe option.

Any ideas?

Here is a Bridge script, to be placed in the folder (Preferences-Startup Scripts (Reveal My Startup Scripts))

#target bridge  


   if( BridgeTalk.appName == "bridge" ) {  


tifLayers= MenuElement.create("command", "Tifs With Layers", "at the end of Tools");


}


tifLayers.onSelect = function () { 


var fileList = Folder(app.document.presentationPath).getFiles("*.tif");


withLayers = new Array();


for(var x in fileList){


var file = fileList;


file.open("r");


file.encoding = 'BINARY';


var dat = file.read();


file.close();


var result;


var pos = [];


var Text= [];


var rex = /Adobe Photoshop Document Data Block/g;


while ((result = rex.exec(dat)) != null) {


pos.push(result.index+(result[0].length));


}


if(pos.length>0) withLayers.push(new Thumbnail(fileList));


dat=null;


}


if(withLayers.length >0){


var foundFiles = app.createCollection("Tifs With Layers");


app.addCollectionMember(foundFiles,withLayers);


    }


};

Sad that there is no “Adobe” way to do this.

Apparently there is a relatively easy Mac OS/Unix way to do this, however I can’t take credit for the following shell script code (not sure if this would work in Windows using say Cygwin or similar):

#!/bin/bash




TIFFEXTENSIONONLY=0




cd "$(dirname "${BASH_SOURCE[0]}")"


SAVEIFS=$IFS


IFS=$(/bin/echo -n $'\n\b')


if [[ TIFFEXTENSIONONLY -eq 0 ]]; then


for N in $(find . -maxdepth 1 -type f ! -name '._*'); do


if [[ $(head -c 2 "$N") == II ]] || [[ $(head -c 2 "$N") == MM ]]; then


tiffutil -dump "$N" | grep '^37724 (0x935c)' > /dev/null


if [[ $? -eq 0 ]]; then


mkdir -p 'MULTIPLE LAYERS'


mv -n "$N" 'MULTIPLE LAYERS'


fi


fi


done


else


for N in $(find -E . -maxdepth 1 -iregex '.*tif(f){0,1}' ! -name '._*'); do


if [[ $(head -c 2 "$N") == II ]] || [[ $(head -c 2 "$N") == MM ]]; then


tiffutil -dump "$N" | grep '^37724 (0x935c)' > /dev/null


if [[ $? -eq 0 ]]; then


mkdir -p 'MULTIPLE LAYERS'


mv -n "$N" 'MULTIPLE LAYERS'


fi


fi


done


fi


IFS=$SAVEIFS


echo TIFF layer checking finished $(date)

    Forgot to say, if any layered Tifs are found a Collection is created with all the layered tifs.
