Export images to folders

Hi Uwe,

thanks for the heads-up. I guess I will handle these issues in the easiest and laziest way by using try{} catch().

Another issue may occur when there are two different images on the same page that are linked from different sources but have the same name, e.g. c:\image_001.jpg, e:\image_001.jpg. In this case there would only be one "image_001.jpg" at the end because the other one got overwritten. But for the moment I will assume that this is not the case and ignore it for now.

#targetengine "imageExporter"

var mydoc = app.activeDocument;
var pages = mydoc.pages;
var allGraphics = null;
var mainFolder_String = decodeURI(mydoc.filePath + "/exported_images");
var mainFolder_Folder = new Folder(mainFolder_String);
var pageFolder = null;
var folderNumber = "";

if(!mainFolder_Folder.exists){
	mainFolder_Folder.create();
}

var progressbar = pbar();
progressbar.show();
progressbar.prog.maxvalue = pages.length;

for(var p = 0; p < pages.length; p++){
	progressbar.prog.value = p;
	progressbar.update();
	
	if(p +1 >= 100){
		folderNumber = p + 1;
	} else if (p +1 >= 10){
		folderNumber = "0" + (p + 1);
	} else {
		folderNumber = "00" + (p +1);
	}
	
	pageFolder = new Folder(mainFolder_String + "/" + folderNumber);
	
	if(!pageFolder.exists){
		pageFolder.create();
	}
	
	allGraphics = pages[p].allGraphics;
	
	for(var g = 0; g < allGraphics.length; g++){
		try {
			var currentGraphic = new File(decodeURI(allGraphics[g].itemLink.filePath));
			
			currentGraphic.copy(mainFolder_String + "/" + folderNumber + "/" + allGraphics[g].itemLink.name);	
		} catch (err) {
			
		}
	}
}

progressbar.close();
alert("Image export completed");

function pbar(){
	var w = Window.find("palette", "progress");
	if(w != null){
		return w;
	}
	
	w = new Window("palette", "progress");
	w.prog = w.add("progressbar", undefined, 0, 100);
	w.prog.preferredSize.width = 200;
	
	return w;
}
