将图像保存在applicationStorageDirectory的目录中 [英] save image in a directory in applicationStorageDirectory

问题描述

我试图将图像文件保存到我的航空项目的applicationStorageDirectory目录中。首先创建目录

  var imageDirectory：File = File.applicationStorageDirectory.resolvePath（vispics）; 
 
 if（imageDirectory.exists）
 {
 Alert.show（目录已经存在）; 
 
} 
 else {
 imageDirectory.createDirectory（）; 
 Alert.show（imageDirectory.nativePath）; 
 
 $ / code> 

下一部分是从我的cam中保存图像，现在保存到applicationStorageDirectory 。这里是我怎么做的
$ b $ pre $ var randInt：int = Math.random（）*（99999 - 1001）+ 1001;
var randStr：String = randInt.toString（）;
var filename：String =+ randStr +。jpg;


var file：File = File.applicationStorageDirectory.resolvePath（filename）;
var wr：File = new File（file.nativePath）;
var stream：FileStream = new FileStream（）;
stream.open（wr，FileMode.WRITE）;
stream.writeBytes（imageData，0，imageData.length）;
stream.close（）;


有没有办法将图像存储在我的vispics目录中？
在此先感谢。

解决方案

试试：

  var file：File = File.applicationStorageDirectory.resolvePath（vispics /+ filename）; 
  

I was trying to save an imagefile to a directory in applicationStorageDirectory of my air project. Created the directory first

 var imageDirectory:File = File.applicationStorageDirectory.resolvePath("vispics");

   if (imageDirectory.exists)
   {
       Alert.show("Directory Already Exists");

   }
   else {
       imageDirectory.createDirectory();
       Alert.show(imageDirectory.nativePath);
   }

The next part is saving image from my cam right now it saves to the applicationStorageDirectory. Here is how i do it

     var randInt:int = Math.random() * (99999 - 1001) + 1001;
      var randStr:String = randInt.toString();
      var filename:String = ""+randStr+".jpg";


        var file:File = File.applicationStorageDirectory.resolvePath( filename );
        var wr:File = new File( file.nativePath );
    var stream:FileStream = new FileStream();
        stream.open( wr , FileMode.WRITE);
        stream.writeBytes ( imageData, 0,imageData.length );
        stream.close();

Is there a way that i can store the image in my "vispics" directory? Thanks in advance.

解决方案

Try:

var file:File = File.applicationStorageDirectory.resolvePath("vispics/" + filename);
