用Adobe AIR制作TexturePacker打包生成图片的切图工具

1.图片导入

private var _file:File;
private var _imageLoader:Loader;

_file = new File(File.desktopDirectory.nativePath);
_file.addEventListener(Event.COMPLETE, OnFileCtrlEvent);
_file.addEventListener(Event.SELECT, OnFileCtrlEvent);
_file.addEventListener(Event.CANCEL, OnFileCtrlEvent);
_imageLoader = new Loader();
_imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, LoadImageComplete);

protected function OnFileCtrlEvent(event:Event):void
{
switch (event.type)
{
case Event.COMPLETE:
//读取文件完成
_imageLoader.loadBytes(_file.data);
break;
case Event.SELECT:
//这里开始读取文件
_file.load();
break;
case Event.CANCEL:
//取消操作
break;
}
}
private function onLoadFileClick():void
{
_file.browseForOpen("请选择需要导入的文件", [filter]);
}
private function LoadImageComplete(event:Event):void
{
//这里已经拿到了图片文件的BitmapData
var sourceBtm:BitmapData = Bitmap(_imageLoader.content).bitmapData;
}

2.PNG图片的显示

3.图片导出

var bmp:BitmapData = new BitmapData("图片宽度", "图片高度", true, 0x00);
bmp.draw(sp);
var bytes:ByteArray = PNGEncoder.encode(bmp);
var path:String = "导出的路径";
var file:File = new File(path);
var fs:FileStream = new FileStream();
try
{
fs.open(file, FileMode.WRITE);
fs.writeBytes(bytes);
fs.close();
}
catch (e:Error)
{
trace(e.message);
}

4.单图预览
