Flex :: Resizing FileReference Image Then Reuploading - Only Reuploads Original Image
Apr 22, 2010
I can;t figure out how to do this. Someone selects and image after calling FileReference.browse(). I take that image and make a thumbnail in flash. Then I upload that image like so:
[Code]...
All this does it upload the original image. How do I change the fileRef to upload the new thumb? I have traced out the size of the "myThumbImage" and it is correct. I have placed it visually on the stage after creating the thumb, and it seems like it works. But when I upload it to an aspx page (that basically just throws it into a folder), it uploads the original larger image.

The following code shows a button that allows you to select a file (should be an image) and display it into an image component. When I select an invalid image (e.g. unsupported image type, a word document), I get the following error:"Error #2044: Unhandled IOErrorEvent:. text=Error #2124: Loaded file is an unknown type.I know I can pass a FileFilter to the FileReference:browse call, but that's beyond the point. My question is... I want to handle the IOErrorEvent myself, what event listener am I missing?
private var file:FileReference = new FileReference();
private function onBrowse():void {
file.browse(null);

I am trying to do an image uploader, user can:
- browse local file with button.browse
- select one and save it as a FileReference.
- then we do FileReference.load() then bind the data to our image control.
- after we make a rotation on it and change the data of image.
- and to finish we upload it to a server.
To change the data of image i get the matrix of the displayed image and transform it then i re-use the new matrix and bind it to my old image:
private function TurnImage():void
{
//Turn it[code]...........
Now the mater is that i really don't know how to send the data as a file to my server cause its not stored in the FileReference and data inside FileReference is readOnly so we can't change it or create a new, so i can't use .upload();.Then i tried HttpService.send but i can't figure out how you send a file and not a mxml.

I am trying to display a bytearray as a resized image. The Image is displaying correctly, but the sizing is off. Let me explain.
First I have the image data encoded so I need to decode the image data
// Instantiate decoder
var decoder:Base64Decoder = new Base64Decoder();
// Decode image data
[Code]....
This works. The image is displayed correctly. However, if I hardcode the image (img) height the resized image is shown correctly, but within a box with the original image's dimensions.
For example, if the original image has a height of 300px and a width of 200px and the img.height property is set to 75; the resized image with height of 75 is shown correctly. But the resized image is shown in the upper left corner of the img container that is still set to a height of 300px and a width of 200px. Why does it do that? And what is the fix?
The best way to illustrate the problem is by placing the image inside a VBox and show the borders of the VBox. From the code block above, if I change the image height and set the image to maintain aspect ratio (which by default is set to true but I add it here for completeness). the problem becomes clear.
// Display image
var img:Image = new Image();
img.height = 75; // Hardcode image height (thumbnail)
img.maintainAspectRatio = true;

I have what seems a straighfoward situation: I update the source property of an image, when the image is loaded i want to redraw the border skin to fit the new size of the image.
newImgEdit.addEventListener(Event.COMPLETE, loadImgComplete);
newImgEdit.source = myurl_ressource;

I am using a mx:Resize effect to change the width of an image in Flex (leaving the height to look after itself) but I want the image to remain vertically centered on the page. Whilst I could calculate the aspect ratio of the photo, and work out the new y value to keep it centred, I would have to include a mx: Move effect too, and I am hopful that Flex has a simpler way. This is for a photo gallery where images are loaded at run-time, and swapped about.
So I really would like to avoid recalculating the aspect ratio and vertical position every time the updateComplete event fires, I tried putting my image inside a mx: VBox with verticalAlign="middle", thinking that the box would do all the centering for me, but this only seems to happen when the app first starts - i need it to gradually adjust the position during the period where the effect plays (to keep it central even when part-way through).
Here's a stripped-down example (which doesn't work):
<mx:Application xmlns:mx="[URL]" layout="absolute" width="600" height="600">
<mx:Resize id="fxResize" target="{imgPhotoA}" widthTo="350" duration="500" />
<mx:Button x="10" y="10" label="Resize" click="fxResize.play()" />
<mx:VBox id="boxPhotoA" x="100" y="20" height="500" width="350" verticalAlign="middle" borderStyle="solid" verticalScrollPolicy="off" horizontalScrollPolicy="off">
<mx:Image id="imgPhotoA" width="60" maintainAspectRatio="true" source="[URL]"/>
</mx:VBox></mx:Application>

But no success.i want to know how to achieve this two things:1) drawing image in its original size, i don't want it to get scaled .2) how to set the size of display screen ? when i ran the code, the display screen(flash) cover whole browser page area ?

i am currently creating a software, i need to upload images form my HDD to server. i can do this with FileReference Object. with this code i can select file.
var f:FileReference;
f.browse(); // for selecting file (object)
and after that i will send that FileReference object to a PHP file and i upload via that PHP file.
but i want to upload file without using FileReference Class i am using File Class on Air 1.0 on Flash, and that class can provide full url of image from my HDD like: D:My Documentsimage01.jpg
there is any way to upload this file on my HDD to server without using browse() class for selecting file on Flash with PHP?
or is there one way to convert File Class (AIR) to FileReference?

I have a basic photo editor I am building in flash but I want the user to be able to load an image into flash before its output to the server. Can this be done or does it have to go to the server first then have flash load it from the server? Trying to avoid the overhead and traffic of sending it on place then downloading the same thing back.

I am currently using filereference in as3 to load a file from the users local disk and display instantly within a loader on the stage. This works fine but i am now needing to load files that are already stored on a server not the local disk, is this possible?
I have tried loading the url into a loader object but this takes far too long if the image is quite big where is filereference is almost instant.
My current code is:
Code:
var mFileReference:FileReference;
browseButton.addEventListener(MouseEvent.CLICK, onBrowseButtonClicked);
function onBrowseButtonClicked(event:MouseEvent):void {
[Code]....
Is there anyway i can take out the browse and selected stages and just load the server based image?

Is there a way to set a default extension when saving an image using FileReference save method?
Code:
var fileReference:FileReference = new FileReference();
fileReference.save( pngData, "image.png" );
If windows is set to "hide known file extensions", only image without extension will be displayed in save dialog. File type is "*.*". Some of my users hat the great idea to add .jpg extension in filename, because they couldn't see one. So file was saved broken as image.jpg.

I was wondering if anyone knew how to scale pictures when doing a website in FLASH. I am creating a flash based website for a friend. I have done all the links and it works greatThe only thing is that the images increase as the web browser is maximised.I would like it to decrease as the web browser is decreased, but to increase to a certain size 900 x 651, and stay that size no matter how big the browser is increased by.

I have been racking my brains trying to figure out how to do this but I can't! The two pictures I have given are different sizes to represent different browser sizes. The 'menu' stays the same size in the same position and the image/ greyblock scales proportionally to the browser keeping the same border sizes around the image.

The images will come in all different sizes so I need to resize them once they are loaded to fit in the containers that they are being loaded into...I thought onEnterFrame was the best way to do this?

Code:

I know that one of the most frequently asked questions is on how to resize a movieclip to fit the dimensions of an image.
My question is similar, but kind of inverse;
I need to resize an image to fit in an empty mc.
Code:
loadMovie("image/imageTest.jpg", mc_appImage);
mc_appImage._width = 190;
mc_appImage._height = 225;
There's my current code... the image loads fine, but does not rezie :/ What am I doing wrong? What do I need do to make this work?
