onSave Event Listener to prompt scaled images – Part 2

Question

Hi Manan,Since the previous Post was successfully closed, I have created a new Post to address a new problem.https://community.adobe.com/t5/indesign/onsave-event-listener-to-prompt-scaled-images/m-p/11408530?page=1#M394764 The script given by Manan, is working fine, but I noticed that if the InDesign file has Vector graphics like .eps or .pdf files, then it is giving an error regarding the event handler, see snapshot.Can you please check if this can be fixed.Thanks,Masood //DESCRIPTION: Event Listener to check if image is scaled <80% or >120% #targetengine "save" app.addEventListener("beforeSave", function(){ for(var i = 0; i < app.documents[0].allGraphics.length; i++) { var img = app.documents[0].allGraphics[i] if((img.absoluteHorizontalScale < 80 || img.absoluteHorizontalScale > 120) || (img.absoluteVerticalScale < 80 || img.absoluteVerticalScale > 120)) { alert("Scaling of Image(s) is below 80% and/or above 120%. Please Fix it!") break; } } })

Works fine for me with your document as well, see the screengrab of me testing your document

I tested on CC2020, but I am not sure why it would break on CC2019. Are you sure you have no other script installed that registers event handler for beforeSave event? If yes then try the following version with try catch, it will silently ignore the graphic that is crashing and move on to check the others

#targetengine "save"
app.addEventListener("beforeSave", function(){
	for(var i = 0; i < app.documents[0].allGraphics.length; i++)
	{
		try
		{
			var img = app.documents[0].allGraphics[i]
			if((img.absoluteHorizontalScale < 80 || img.absoluteHorizontalScale > 120) || (img.absoluteVerticalScale < 80 || img.absoluteVerticalScale > 120))
			{
				alert("Scaling of Image(s) is below 80% and/or above 120%. Please Fix it!")
				break;
			}
		}catch(e){}
	}
})

Hi Masood,testing eventlisteners on object app can be a bit tricky. Especially if you execute a modified script the second or third time without removing the listener first.If you want to get a clean situation do a restart of InDesign before running the script again.It's also a good idea to give the eventlistener a "unique" name and test if it is already running. Warning! Do NEVER do something like this:app.eventListeners.everyItem().remove(); You will be able to wreck other running scripts from other developers that are started at runtime or the user is currently using with a ScriptUI palette kind of window. Also note, that InDesign itself is using some scripts at start-up that are pre-installed. Regards,Uwe Laubender( ACP )
