KirSizer Flex AIR Image Sizer app Part 14

In this tutorial we will make the log text area refresh when it reaches bottom and add an option to skip files if their size is already correct.

When I was testing KirSizer on a big amount of images, I noticed that quite a lot of images already had the correct size and thought that it would take less time if I just checked if the pictures size are already correct and skip them. However, just skipping all files for just having correct sizes is wrong, since KirSizer is not only capable of resizing images, but also renaming them, changing their format and also compress pictures. That is why I decided to include the "Skip" feature as a toggleable option.

I also noticed that the log text can get quite big. To prevent any problems with too large text, I decided to clear the text area every time it reaches 24 lines. This way it is still informative, but takes much less space and perhaps this way it even is more comprehendable.

First well do the text limitation feature. Create a function called checkLineLimit() which checks if the number of lines exceeds 24 and set logAreas text to blank if so.

private function checkLineLimit():void {
if (countLines(logArea.text) > 24) {
logArea.text = "";
}
}

The countLines() function that I used returns an integer value, which equals to the number of elements of the array thats created by splitting the text areas text by new line characters:

private function countLines(text:String):int {
var splittedText:Array = text.split("
");
var lines:int = splittedText.length;
return lines;
}

We call this function in the beginning of nextAction(), in its first if statement:

private function nextAction():void {
if (currentNum < selectedFiles.length) {
checkLineLimit();
var isFolder:Boolean = false;
var folder:File = new File(selectedFiles[currentNum].path);
// if its a folder, create a global array that stores all image files of the folder
if (folderArray.length > 0) isFolder = true;
if (folder.exists && selectedFiles.length > currentNum && selectedFiles[currentNum].type == 1 && folderArray.length == 0) {
isFolder = true;
folderArray = [];
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]);
}
}
if (selectedFiles[currentNum].num != folderArray.length) {
appendHighlight("ERROR: incorrect amount of image files found in folder " + folder.name + "
", 0xff2222);
errorText += "Not enough or too many image files found in folder " + folder.nativePath + " (some files were removed/added before it was this folders turn to be resized)" + File.lineEnding;
totalErrors++;
}
}
if (!folder.exists && selectedFiles.length > currentNum && selectedFiles[currentNum].type == 1 && folderArray.length == 0) {
appendHighlight("ERROR: folder not found (" + folder.name + ")
", 0xff2222);
errorText += "Folder was not found at " + folder.nativePath + File.lineEnding;
totalErrors++;
currentNum++;
nextAction();
return;
}
resizeNext(isFolder);
}else {
progressBar.setProgress(totalFiles, totalFiles);
appendHighlight("Operation complete!
Errors: " + totalErrors + "
Files resized: " + successFiles + "/" + totalFiles, 0xffff44);
errorText += "----------------------" + File.lineEnding + "Total errors: " + totalErrors + File.lineEnding + "Files resized: " + successFiles + "/" + totalFiles;
buttonError.enabled = true;
buttonReturn.enabled = true;
statusText.setStyle("color", 0x44ff44);
statusText.text = "COMPLETED";
}
}

Now lets work on the skipping feature. Go to the options screens NavigatorContent object and create a new CheckBox object with an id skipCorrect and selected property set to false:

<s:NavigatorContent width="100%" height="100%" hideEffect="fadeOut" showEffect="fadeIn">

<s:Label/>

<s:Label/>

<s:Button label="Resize" width="100%" click="beginResize();" />
</s:VGroup>
</s:NavigatorContent>

Now were going to add some major changes to the resizeNext() function.

However, the code that we add will not be very big. Were just going to add a needResize boolean value which is set to false if the new height and width equal the old height and width of the image. We are, however, going to have to move large piece of code from the onTimer() function into the resizeNext() function itself.

We are doing this so that we can calculate new size of the picture before starting the timer and wasting time on it. We just load the image, then set all the variables, such as newExtension, currentW, currentH, newW, newH, ratio, newName and needResize, calculate their values, check if the size has changed, and if it hasnt - dont even bother with the timer and just call nextAction(). Otherwise, start the timer and resize normally.

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++;
}
}

if(file!=null) logArea.appendText("#" + currentProgress + " (" + file.name + ")
");

// Error: file not found
if (file != null && !file.exists) {
canProceed = false;
appendHighlight("ERROR: File not found

errorText += "File not found at location: " + file.nativePath + File.lineEnding;
totalErrors++;
nextAction();
}


// Error: bad extension
if (file != null && (file.exists && file.extension.toLowerCase() != "png" && file.extension.toLowerCase() != "jpg" && file.extension.toLowerCase() != "jpeg")) {
canProceed = false;
appendHighlight("ERROR: Incorrect extension

var bitmapData:BitmapData = new BitmapData(newW, newH, false, 0xffffff);

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