Resize Bitmap image in image control in flex3

[mousumi_78]

I am loading an image in image control initially. Then I am applying color
transform to that image and want to load that bitmap image in flex3. That is
working, but automatic resize is not working then. If I load another image then
auto resize is working fine. Doesnt Image control support resizing of bitmap
object of same image?.

Here is the portion of code:
<mx:Image source="{imgpath}" id="myImage"
creationComplete="imageCompleted();" x="20" y="30" width="365" height="440"
maintainAspectRatio="true"
/>
private function applyColor(event:Event):void{

myBitmapDataObject = new BitmapData(myImage.width, myImage.height, true,
0x00CCCCCC);

myBitmapDataObject.draw(myImage.content);
myBitImage = new Bitmap(myBitmapDataObject);

myBitmapDataObject.colorTransform(myBitmapDataObje ct.rect, new
ColorTransform(1, 1, 1, 1, 39, 76, 135, 100));
myImage.removeChildAt(0)
myImage.load(myBitImage);


}

Any help is appreciated.

You need to create the BitmapData as the original loaded image size, not the
mx:Image height and width. You are simply transforming/copying only a portion
of the original size that corresponds to the Image size. Ie. say you have a
400x400 image and your Image is 100x100. Your BitmapData is being created at
100x100, NOT 400x400 as you would need to do. Just because you resize the
Image, doesn't mean the underlying BitmapData is also resized.

Also, generally, addChild would be used after removeChild, never used load
myself. Not sure if it matters.
