Hi @davidn5918184 (and @Eugene Tyson) I actually couldn't get the bt.onResult function to execute at all. Is that a known thing? I've hardly done any BridgeTalk so I have no idea. I'm on MacOS, so maybe on Windows onResult works?
@davidn5918184 I've made some adjustments to your code, mostly for your interest, and my learning, and I've got it working. It's not super pretty, but has improved a bit I hope.

Hi @davidn5918184 , Bridgetalk can be difficult. Rather than editing your code, here is a example of template I use where I write a regular Photoshop function and retrieve it as a string for the BridgeTalk body object—I find it’s a lot easier to debug the Photoshop function doing it this way.

But it simply didn't execute for me
Hi Mark, this minimal example shows how the result is handled:
runPhotoshop(new BridgeTalk());
function runPhotoshop(bt){
bt.target = "photoshop";
bt.body = psScript.toString() + "\rpsScript();";
bt.onResult = function(resObj) {
alert("InDesign is now running. The returned result is: " + resObj.body);
}
//this would return the result asynchronously
//the result never makes it back to InDesign and there is no alert
//bt.send();
//this sends the result synchronously with a timeout as the parameter
bt.send(100);
function psScript() {
var s = "Hello World"
//nothing returned
//return s
}
}
Result:
runPhotoshop(new BridgeTalk());
function runPhotoshop(bt){
bt.target = "photoshop";
bt.body = psScript.toString() + "\rpsScript();";
bt.onResult = function(resObj) {
alert("InDesign is now running. The returned result is: " + resObj.body);
}
//this sends the result synchronously with a timeout as the parameter
bt.send(100);
function psScript() {
var s = "Hello World"
return s
}
}
The result when the Photoshop function returns a string

Hi @davidn5918184 , Bridgetalk can be difficult. Rather than editing your code, here is a example of template I use where I write a regular Photoshop function and retrieve it as a string for the BridgeTalk body object—I find it’s a lot easier to debug the Photoshop function doing it this way.
I don’t think a delay will help—you have to return the new tif file path via resObject.body to InDesign after the Photoshop code is complete. In this example the image to open is a .psd, and I’m saving it as a tif and replacing it with the Photoshop function’s returned file path. I’m not including your action descriptor code for the mask:
maskImage()
//a variable for the new .tif file path
var np;
/**
* An InDesign function to run
* creates a Bridgetalk instance and opens a selected image
* @ return void
*/
function maskImage(){
if (app.selection.length > 0) {
var s = app.selection[0]
if (s.constructor.name == "Image") {
var img = s.itemLink;
var b = new BridgeTalk();
openImage(img.filePath, b);
img.relink(File(np))
alert("Updated Link To:\r" + np)
}
} else {
alert("Select an Image")
return
}
}
/**
* Open the selected link in Photoshop
* @ param the image file path
* @ param A single BridgeTalk instance created in InDesign
* @ return void
*
*/
function openImage(fp, bt){
bt.target = "photoshop";
//Get the body from the psScript function below Note a string parameter is '"+fp+"'
bt.body = psScript.toString() + "\rpsScript('"+fp+"');";
//This is missing from your code resObj.body is
//the returned value of the Photoshop function
//sent back to InDesign
//the new file path in this case
bt.onResult = function(resObj) {
np = resObj.body;
}
bt.onError = function( inBT ) { alert(inBT.body); };
bt.send(8);
/**
* A Photoshop function to run
* @ param a
* @ return value
*/
function psScript(fp) {
var of = open (File(fp));
//get the opened file’s name
var n = fp.split( "." )
if ( n.length > 1 ) {
n.length--;
}
n = n.join(".");
//add your Photoshop actions and code here...
//TIFF save options
var so = new TiffSaveOptions();
so.transparency = true;
so.layers = true;
so.alphaChannels = true;
so.embedColorProfile = true;
so.imageCompression = TIFFEncoding.NONE;
of.saveAs(new File(n + ".tif"), so, true);
of.close(SaveOptions.DONOTSAVECHANGES);
//return the file path of the new tif back to InDesign
return n + ".tif"
}
}
Before and after:
I don’t think so, I read it as the time allowed for a synchronous return of the Photoshop function‘s value. The parameter description is in the link above.
Here’s a generic example that throws up 3 alerts—1st when Photoshop is running, 2nd on the return to InDesign, and 3rd from InDesign with the returned Photoshop values:
//global variabes available to both ID and PS
var a = [];
var str = "Hello";
IDtoPS();
/**
* An InDesign function to run
* creates a single Bridgetalk instance
* @ return void
*/
function IDtoPS(){
//I create a single Bridgtalk instance in InDesign
//in case I want to run a loop
var bt = new BridgeTalk();
//variables to pass to the PS function
var bol = true;
var s = "World"
runPhotoshop(bol, s, bt);
//the global array returned from Photoshop
alert("Returned From Photoshop: " + a[2] + " " + a[1])
}
/**
* A function to run in Photoshop
* @ param a boolean example
* @ param a string example
* @ param a single bridgetalk object to use
* @ return void
*
*/
function runPhotoshop(isBoolean, theString, bt){
//open Photoshop and run psScript()
bt.target = "photoshop";
//the function string with a string variable and 2 parameters
//Note a string parameter is '"+theString+"'
//Other parameters are "+isBoolean+"
bt.body = "var aString = '"+str+"'; \r" + psScript.toString() + "\rpsScript("+isBoolean+",'"+theString+"');";
bt.onResult = function(resObj) {
//split the returned result body string into an array
a = resObj.body.split(',');
//return to InDesign
alert("InDesign is now Running");
}
bt.onError = function( inBT ) { alert(inBT.body); };
bt.send(1000);
//$.writeln(bt.body)
function psScript(isBoolean, theString) {
//var doc = app.documents.add();
app.bringToFront();
//change the string variable value
aString += " There"
//Photoshop is running
alert("Photoshop Running; 1st function Param= " + isBoolean +"; 2nd Param= " + theString+ "; 1st Var= " + aString)
return [isBoolean, theString, aString]
}
}
