Disable alerts in batch script?

[dclaarit]

How can I stop alerts from stopping my batch script?

I've found and adapted a script to do batch photomerges on a group photos that might be related. There's only one issue: Some of them aren't, and the photomerge script throws an alert ("Some images could not be aligned") and stops dead until I dismiss the dialog. That's...not automation. I tried to tell it to not display dialogs:

displayDialogs = DialogModes.NO;

alert('displayDialogs='+displayDialogs);

But that just doesn't work. (When you think about it, the second line shouldn't throw the alert telling me the value of displayDialogs, but it does).

I've tried various incantations:

app.displayDialogs

photomerge.displayDialogs

I've even put the DialogModes.NO into the photomerge script itself, but to no avail.

I guess I can perform surgery on the photomerge.jsx script itself, but all the documentation says that displayDialogs should work. I'm back on Photoshop CS6.

I also tried:

app.scriptPreferences.userInteractionLevel = UserInteractionLevels.neverInteract

but this appears to be for a different version, as it complains that UserInteractionLevels is undefined.

I am using python to open the com object and then:

object.DoJavaScriptFile("/N/Images/panoramas/photomerger.jsx", ["a", "b"])

photomerger.jsx starts:

var runphotomergeFromScript = true;

#include "/C/Program Files/Adobe/Adobe Photoshop CS6 (64 Bit)/Presets/Scripts/Photomerge.jsx"

displayDialogs = DialogModes.NO;

alert('displayDialogs='+displayDialogs);

...

photomerge.createPanorama(jpg_list, false);

I even tried to figure out how to override alert(), but I couldn't get that to work either.

Any ideas before I hack up the script?

Thanks!

If that is what you're asking for cannot you just comment alert in your script like this (Photoshop CS6 EXTENDED / line 461):

//alert(localize("$$$/AdobePlugin/Shared/Photomerge/alignbad=Some images could not be automatically aligned"));

Thanks! Yes, my backup plan is to make a copy of the script and go in and rip out all of the alerts...or well, make the error returns that I could catch. But I would prefer to have a generic automation solution.

a()
function a()
    {
    function alert() {}
    /////////// your main code start
    var runphotomergeFromScript = true;
    #include "/C/Program Files/Adobe/Adobe Photoshop CS6 (64 Bit)/Presets/Scripts/Photomerge.jsx"
    displayDialogs = DialogModes.NO;
    alert('displayDialogs='+displayDialogs);
    ///...
    photomerge.createPanorama(jpg_list, false);
    /////////// your main code end
    }

This only works in the outer level: It suppresses the

alert('foo');

but the alert in photomerge script still fires.

So I guess I could modify the photomerge script itself with this: It would be easier than changing all of the alerts themselves!

(I've tried for literally the last 90 minutes to set my preferences and/or see the thing that let's me paste code, but all I get is some stupid "We could not complete your request. Please check the form for details.", so...my apologies for the ugly post):

do_merge()

function do_merge() {

  function alert() {}

  displayDialogs = DialogModes.NO;

  alert('foo')

  photomerge.createPanorama(jpg_list, false);

So in the end, I edited the Adobe script and changed all of the alert() calls to throw(), which I catch and then cleanup the active document. I guess that makes Kukurykus' answer the most correct...

Thanks for the help!
