KirSizer Flex AIR Image Sizer app Part 11

Today we will add the main feature for our resizing program - the resizing of images!

First we need to add the ability to select an output destination. Declare a variable destinationPicked, a String value with blank text as default:

private var destinationPicked:String = "";

Now go to the part where destination-related objects are put on screen and set the text inputs id to destinationInput, and the "Browse" buttons click event handler to pickDestination():

<s:Label>Output destination:</s:Label>
<s:HGroup verticalAlign="middle">
<s:RadioButton id="oldDestination" label="Same directory" groupName="destinationGroup" selected="true" />
<s:RadioButton id="newDestination" label="Specified directory" groupName="destinationGroup" />
</s:HGroup>
<s:HGroup verticalAlign="middle" width="100%">
<s:TextInput width="100%" id="destinationInput" enabled="{newDestination.selected}" text="Select destination..." editable="false" />
<s:Button width="80" label="Browse" enabled="{newDestination.selected}" click="pickDestination();" />
</s:HGroup>

Find the part where you create the JPG quality slider and set the id of the slider to qualitySlider:

<s:Label>Output JPG quality:</s:Label>
<s:HSlider id="qualitySlider" width="100%" minimum="1" maximum="100" value="100" />

Now go to beginResize() function and add a new if statement which doesnt let the user to start resizing if the destination is not set to "the same destination" and is not picked:

private function beginResize():void {
var canProceed:Boolean = true;
if (selectedFiles.length == 0) {
canProceed = false;
Alert.show("No files or folders are selected.", "Cant start resizing!");
}
if (nameInput.text.indexOf(%initialName%) < 0 && nameInput.text.indexOf(%num%) < 0) {
canProceed = false;
Alert.show("No wildcards were used in the name field! They are essential for each output file to have an unique name.", "Cant start resizing!");
}
if (newDestination.selected && destinationPicked == "") {
canProceed = false;
Alert.show("No destination set!", "Cant start resizing!");
}
var testName:String = nameInput.text.replace("%initialName%", "");
testName = testName.replace("%num%", "");
if(testName.indexOf(/)>=0 || testName.indexOf("\")>=0 || testName.indexOf(?)>=0 || testName.indexOf(%)>=0 ||
testName.indexOf(*)>=0 || testName.indexOf(:)>=0 || testName.indexOf(|)>=0 || testName.indexOf(")>=0 ||
testName.indexOf(<) >= 0 || testName.indexOf(>) >= 0 || testName.indexOf(.) >= 0) {
canProceed = false;
Alert.show("Illegal characters in the name field! Make sure file name field does not contain these characters: /  ? % * : | " < > . ", "Cant start resizing!");
}
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...
");
currentNum = 0;
totalErrors = 0;
progressBar.setProgress(0, totalFiles);
nextAction();
}
}
}

Create a new function pickDestination(), which sets destinationPicked value to the selected directorys nativePath:

private function pickDestination():void {
var file:File = new File();
file.browseForDirectory("Select ouput destination");
file.addEventListener(Event.SELECT, outputSelect);
function outputSelect(evt:Event):void {
destinationPicked = file.nativePath;
destinationInput.text = destinationPicked;
}
}

Now lets go to resizeNext() function and work on actually exporting the result files. Were only going to have to work in the internal onTimer() function.

Firstly, lets fix the %num% wildcard changing to currentNum and not currentProgress, displaying incorrect number:

newName = newName.replace("%num%", currentProgress);

Now, before we call nextAction() in the end of the function, lets add some code that creates a BitmapData object with the picture in it, resize it using a Matrix object, encode it using an approporiate encoder (depending on newExtension value), and save the output file to the correct destination.

First we create the bitmap data object and add the image to it using its draw() object. Create a Matrix object beforehand and use its scale() method to resize the picture:

var matrix:Matrix = new Matrix();
matrix.scale(newW/currentW, newH/currentH);
var bitmapData:BitmapData = new BitmapData(newW, newH, false, 0xffffff);
bitmapData.draw(loader.content, matrix, null, null, null, true);

Then we check what extension we are saving the file in, and create an approporiate encoder object and encode the bitmap data into a byte array:

var encoder:IImageEncoder;
if (newExtension == "jpg") encoder = new JPEGEncoder(qualitySlider.value);
if (newExtension == "png") encoder = new PNGEncoder();
var byteArray:ByteArray = encoder.encode(bitmapData);

Then we pick the correct destination by checking which of the destination radio buttons is currently selected, and apply the correct path to a "newfile" object. Then we create a stream to write the bytes into the file:

var newfile:File;
if (newDestination.selected) newfile = new File(destinationPicked + File.separator + newName + "." + newExtension);
if (oldDestination.selected) newfile = new File(file.parent.nativePath + File.separator + newName + "." + newExtension);
var stream:FileStream = new FileStream();
stream.open(newfile, FileMode.WRITE);
stream.writeBytes(byteArray);
stream.close();

And we are done! The program can actually resize stuff now!
