Check if Pathitem exists and set Metadata accordingly

Hi there,

i'm a complete newbie to PS-Scripting and have a problem to solve. Hopefully someone can help me on this:

i am handing Jpeg-Files to PhotoshopCS4 with Enfocus Powerswitch on a Macintosh, then the Script has to check if there is a Pathitem called "Path 1". On success a new Metadatafield called "Path 1" of Type "Boolean" has to be created and set to "1" and the Action "W-S-Path" from Action-Set "SWITCH" has to be called. On failure a new Metadatafield called "Path 1" of Type "Boolean" has to be created and set to "0".
I hope that its possible to get that done somehow, as i have no clue

Thanks in advance.

patrick

You can't have a metadata field with a space in it, so this uses Path_1 ...

Code: Select allmain();
function main(){
if(!documents.length) return;
if (ExternalObject.AdobeXMPScript == undefined) ExternalObject.AdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");
var psNamespace = "http://ns.pathInfo/1.0/";
var psPrefix = "path:";
XMPMeta.registerNamespace(psNamespace, psPrefix);
xmp = new XMPMeta( app.activeDocument.xmpMetadata.rawData );
xmp.deleteProperty(psNamespace, "Path_1");
try{
var path = activeDocument.pathItems["Path 1"];
xmp.setProperty(psNamespace, "Path_1",1);
app.doAction("W-S-Path" , "SWITCH");
}catch(e){
xmp.setProperty(psNamespace, "Path_1",0);
}
app.activeDocument.xmpMetadata.rawData = xmp.serialize();
}

Is it possible to change the script that it checks if any path exists or not?

Kind regards,
Jörg

Yes, you could do something like this...

Code: Select allmain();
function main(){
if(!documents.length) return;
if (ExternalObject.AdobeXMPScript == undefined) ExternalObject.AdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");
var psNamespace = "http://ns.pathInfo/1.0/";
var psPrefix = "path:";
XMPMeta.registerNamespace(psNamespace, psPrefix);
xmp = new XMPMeta( app.activeDocument.xmpMetadata.rawData );
xmp.deleteProperty(psNamespace, "Path_1");
if(activeDocument.pathItems.length >0){
xmp.setProperty(psNamespace, "Path_1",1);
//amend action to suit
//app.doAction("W-S-Path" , "SWITCH");
}else{
xmp.setProperty(psNamespace, "Path_1",0);
}
app.activeDocument.xmpMetadata.rawData = xmp.serialize();
}
