Dynamic image display


Level 1
Hello Falks!

I am new and novice to Flex platform and I jumped into Flex3.
I have a good background of Java.

I tried to make a sample application that reads data from
mysql5.1 DB and displays on DataGrid columns.

One of my table coumn is Image [BLOB]. When i try retriving
it via Remote Object service with BlazeDS data service, it does not
display me the Images.

I am pasting the code of my MXML.


<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="








import flash.display.Bitmap;

import mx.controls.Image;

import mx.graphics.ImageSnapshot;

import mx.graphics.codec.*;

import mx.graphics.codec.JPEGEncoder;

import mx.controls.Alert;

import mx.collections.ArrayCollection;

private var reviewList:ArrayCollection;

import mx.controls.TileList;

private var myTileList:TileList;

private function getResults():void {

reviewList = remoteobj.getPersonDetails.lastResult;

var tf:TextFormat = new TextFormat();

//set textFormat font, color, and size

tf.font = "Verdana";

tf.bold = true;

tf.color = 0x990000;

tf.size = 16;

myTileList= new TileList();

myTileList.dataProvider =reviewList[0].image as Bitmap;

// set column and row values

myTileList.columnWidth = 200;

myTileList.rowHeight = 140;

myTileList.columnCount = 1;

myTileList.rowCount = 2;

myTileList.width = 210;

myTileList.height = 305;

//set styles

myTileList.setStyle("contentPadding", 5);

// add to the display (Stage)





<mx:RemoteObject id="remoteobj" destination="personmap"

<mx:Image id="img" />

<mx:DataGrid id="dg" dataProvider="{reviewList}" >


<mx:DataGridColumn dataField="person_id"
headerText="PersonID" />

<mx:DataGridColumn dataField="fname"

<mx:DataGridColumn dataField="lname"

<mx:DataGridColumn headerText="Image">




<mx:Image id="myImage"

height="100" width="100"








<mx:Button label="Get Data" click="getResults()"/>

Hi, did you ever get any response to this or solve this
problem? I am trying to do a very similar thing and I am not having
much luck.

Does anyone know of an example?

try the following these steps,

1. on the server side, return the blob data as byte[]. that
will be serialized into a ByteArray object in AS3

2. use flash.Display.Loader as the container for the image.
load the ByteArray using Loader.loadBytes(...)

3. add the Loader object to the display
