KirSizer - Flex AIR Image Sizer app: Part 10

In today's tutorial we will add support for working with not just separate files from the selected list, but also folders.

First of all go to the beginResize() function and in the if(canProceed) statement set progressBar's progress to 0 manually, and call nextAction() instead of resizeNext().

if (canProceed) {
contentStack.selectedIndex = 3;
var timer:Timer = new Timer(400, 1);
timer.addEventListener(TimerEvent.TIMER_COMPLETE, onTimer);
timer.start();
function onTimer(evt:TimerEvent):void {
buttonError.enabled = false;
buttonReturn.enabled = false;
logArea.text = "";
logArea.appendText("Beginning resizing of " + totalFiles + " files...\n");
currentNum = 0;
totalErrors = 0;
progressBar.setProgress(0, totalFiles);
nextAction();
}
}

Now comes the complicated part.

Each object in the selectedFiles array is either a file or a folder. Right now, the currentNum value represents which object is currently being resized, and since we only resized files, currentNum also represented the number of the file that was being resized, so we could use it as the current value in progressBar. Now, we'll just increase a value unrelated to currentNum and apply it to progressBar.

Since an object in this array can be either file or a folder, we need to check what it is in resizeNext(). It will receive a boolean value (true if its a folder, false if its a file), and we can use that to execute approporiate code. For files, we increase currentNum and set file object to the one in selectedFiles under currentNum-1 index. For folders, we use a global folderArray (values to which are applied beforehand and are the image files in the current folder, will explain this shortly) and take the last element from this array and use it as the file. We also remove the last file from this array and basically keep doing the same thing until folderArray is empty. When it's empty, only then we increase currentNum and move on to the next object in selectedFiles.

In nextAction() function, we check if the folderArray is empty. If it is not, we call resizeNext(true) (we actually call resizeNext(isFolder) later, but we set isFolder to true so that the true value is passed). Then we check if the next element in the queue is a folder and folderArray's length is currently 0. If it is so, we loop through the children of this array and add image files to folderArray. Then we set isFolder to true and call resizeNext(isFolder).

Also, in nextAction() function we compare currentNum to selectedFiles.length instead of totalFiles.

The program workflow is represented in this scheme:



The nextAction() function with updates:

private function nextAction():void {
if (currentNum < selectedFiles.length) {
var isFolder:Boolean = false;
// if its a folder, create a global array that stores all image files of the folder
if (folderArray.length > 0) isFolder = true;
if (selectedFiles.length > currentNum && selectedFiles[currentNum].type == 1 && folderArray.length == 0) {
isFolder = true;
folderArray = [];
var folder:File = new File(selectedFiles[currentNum].path);
var allContent:Array = folder.getDirectoryListing();
for (var i:int = 0; i < allContent.length; i++) {
if (allContent[i].isDirectory == false && (allContent[i].extension.toLowerCase() == "png" || allContent[i].extension.toLowerCase() == "jpg" || allContent[i].extension.toLowerCase() == "jpeg")) {
folderArray.push(allContent[i]);
}
}
}
resizeNext(isFolder);
}else {
logArea.appendText("Operation complete!");
buttonError.enabled = true;
buttonReturn.enabled = true;
}
}

The updated resizeNext() function:

private function resizeNext(isFolder:Boolean):void {
var file:File;
var canProceed:Boolean = true;
var loader:Loader;
var currentProgress:int = progressBar.value + 1;
progressBar.setProgress(currentProgress, totalFiles);

// if its a file
if (!isFolder){
currentNum++;
file = new File(selectedFiles[currentNum - 1].path);
}

// if its a folder
if (isFolder) {
file = folderArray.pop();
if (folderArray.length == 0) currentNum++;
}

logArea.appendText("#" + currentProgress + " (" + file.name + ")\n");

// Error: file not found
if (!file.exists) {
canProceed = false;
logArea.appendText("ERROR: File not found\n");
totalErrors++;
nextAction();
}


// Error: bad extension
if (file.exists && file.extension.toLowerCase() != "png" && file.extension.toLowerCase() != "jpg" && file.extension.toLowerCase() != "jpeg") {
canProceed = false;
logArea.appendText("ERROR: Incorrect extension\n");
totalErrors++;
nextAction();
}

// load image
if (canProceed) {
loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoadComplete);
loader.load(new URLRequest(file.url));
}

// start timer
function onLoadComplete(evt:Event):void {
var timer:Timer = new Timer(500, 1);
timer.addEventListener(TimerEvent.TIMER_COMPLETE, onTimer);
timer.start();
}

function onTimer(evt:TimerEvent):void {
// new name
var newName:String = nameInput.text.replace("%initialName%", file.name.substr(0, file.name.lastIndexOf('.')));
newName = newName.replace("%num%", currentNum);

// new extension
var newExtension:String;
if (formatCombo.selectedIndex == 0) newExtension = file.extension;
if (formatCombo.selectedIndex == 1) newExtension = "jpg";
if (formatCombo.selectedIndex == 2) newExtension = "png";

// new size
var currentW:int = loader.content.width;
var currentH:int = loader.content.height;
var newW:int;
var newH:int;
var ratio:Number;

if (actionCombo.selectedIndex == 0) {
if (widthMeasure.selectedIndex == 0) newW = newWidth.value/100 * currentW;
if (widthMeasure.selectedIndex == 1) newW = newWidth.value;
if (heightMeasure.selectedIndex == 0) newH = newHeight.value/100 * currentH;
if (heightMeasure.selectedIndex == 1) newH = newHeight.value;
}

if (actionCombo.selectedIndex == 1) {
ratio = currentW / currentH;
if (widthMeasure.selectedIndex == 0) newW = newWidth.value/100 * currentW;
if (widthMeasure.selectedIndex == 1) newW = newWidth.value;
newH = newW / ratio;
}

if (actionCombo.selectedIndex == 2) {
ratio = currentW / currentH;
if (heightMeasure.selectedIndex == 0) newH = newHeight.value/100 * currentH;
if (heightMeasure.selectedIndex == 1) newH = newHeight.value;
newW = newH * ratio;
}

if (actionCombo.selectedIndex == 3) {
ratio = currentW / currentH;
newW = newWidth.value;
newH = newW / ratio;
if (newH > newHeight.value) {
newH = newHeight.value;
newW = ratio * newH;
}
}

// log
logArea.appendText("Resized from " + currentW + "x" + currentH + " to " + newW + "x" + newH + "\n");
logArea.appendText("Renamed to " + newName + "." + newExtension + "\n");

nextAction();
}

}
