[flexcoders] How to mask a color on a bitmapdata object?
I have the following situation: I have n bitmapdata objects of the same width and height. Each bitmapdata object have some black pixels (0x00) and the rest of the pixels are of different colors. The position of the black pixels is different in each bitmapdata object. I want to be able to create a new bitmapdata object that contains the union of the black pixels of the other objects and ignore the other colors. I know I can loop through the bitmapdata objects and check with pixels are black and create the resulting one. However, I need to repeat that process many times with tons of images that could be as large as 1000 by 100 pixels. hence, I would like to know if there is a way to create that resulting bitmapdata object, without the need to loop. For instance, the compare method allows to compare 2 bitmapdata objects to see which ones has the same colors in the same positions as: var diff::BitmapData = bd1.compare.bd2 diff will have a value of 0x00 for the pixels that are of the same color in bd1 and bd2. In may case I want to do something like that but to create a bitmapdata object with all black pixels. Any suggestions?
[flexcoders] How to create Value Objects dynamically at run time?
I am building a visualization app in which I paste an excel table and then I need to manage the data as value objects. The user can paste different tables with different columns each time, so I don't know a priory the type of the data objects. Once the data is loaded the user is asked to identify what kind of data in each column (variable) is, such text, number, date, etc. Hence, I would like to create value objects dynamically, but I don't know how. Any suggestions?

[flexcoders] FileReference Load local files - how to use it to load flv or MP4 files?
I am trying to use the FileReference stuff to load flv and/ or mp4 files to Flash player.

[flexcoders] Problem displaying item renderer on on TileList
I am creating an app. in which a need to display some thumbnails on a TileList,
but the thumbnails are not visible on the TileList. However, if a click on a
tile it does what it is suppose to do and it creates the number of tiles
according to the data provider, only the tiles are not visible.
My code is:
mx:Panel width=100% height=100% title=Select Video
mx:TileList id=videoResults dataProvider={videos} width=100%
height=100% itemRenderer=components.Thumb styleName=L1
itemClick=onVideoSelected(event) /
/mx:Panel
the item renderer component is:
?xml version=1.0 encoding=utf-8?
mx:VBox xmlns:mx=http://www.adobe.com/2006/mxml; width=200 paddingTop=0
paddingBottom=0 xmlns:controls=com.asfusion.controls.*

The data provider is an XMLList.
If a replace the TileList with a list or horizontalList the item renderer is
visible. Can someone tell me what I am doing wrong?

Although not FLV, I wrote a sample AMF 0/AMF 3 client based on

which mentions the ActionScript source which was submitted to BlazeDS as an
attachment to BLZ-209. See amf.zip at:
https://bugs.adobe.com/jira/browse/BLZ-209
For FLV, the key is to understand the Type column for each field. I took a
quick look at the spec and it seems to use conventions similar to the SWF
format.
private function onComplete(e:Event):void
{
var ba:ByteArray = loader.data as ByteArray;
if (ba != null ba.length 9)
{
// Peek at the first 3 bytes to check for 'F' 'L' 'V'
if (ba.readUnsignedByte() == 0x46 ba.readUnsignedByte() == 0x4C
ba.readUnsignedByte() == 0x56)
{
ba.position = 0;
decodeFLV(ba);
}
}
}
i.e. For UI8, use readUnsignedByte() to get a uint
For UB[n], use readUnsignedByte() and then shift to find the relevant bit(s)
for each flag.
For UI32, use readUnsignedInt() to get a uint
For UI24, use 3 successive readUnsignedBytes() and shift values appropriately
to form a uint from the 24bits.
etc...

[flexcoders] Upload file to server from AIR app
I am trying to upload a video from an AIR app to a server. All the
examples I have seen use the fileReference.browse, but I don't need to
browse any directory.
I am using RED5 to capture a video to the local hard drive.
I know that the name and path of the file. Thus, the question is how I
write the upload stuff. I am trying this:
private function uploadTheFile():void
{
var fileToUpload:File = new File(path+captureTest.flv);
fileToUpload.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA,
onUploadComplete);
var uploadRequest:URLRequest = new URLRequest();
uploadRequest.method = POST;
uploadRequest.url = myURL;
try{
fileToUpload.upload(uploadRequest);
}
catch (error:Error){
trace(error uploading the file);
}
}
I am getting a I/O Error: Error #2038.
I would appreciate if someone has an example with the corresponding
PHP script (maybe I have an issue with the PHP script)
Thanks,
Gilbert

[flexcoders] ColumnChart Question: How to drag the columns to change values dynamically?
I am creating a Column Chart based on values that I read from an XML file. I want the user to be able to modify those values, by dragging the top of the chart (on the y axis). I see in the documentation that there are many drag-related events by I need help to figure out how to implement this. Gilbert

[flexcoders] Re: Capturing and recording video with AIR
Thanks Greg and William, I now you can do that with FMS/Red 5, but on the tour Adobe people specifically mentioned that the recording could be done with AIR directly. I even asked after they showed the slides and they said yes (unfortunately they did not give more details). Greg, can I install the Flash Media Encoder (FME) on a local machine and record a FLV? Is there a way to manage the interaction from an AIR app. ? Or can I launch the FME from a Zinc 3 application made with Flex?

[flexcoders] Capturing and recording video with AIR
On the Flex 3/Air pre-tour it was mentioned that it is possible to capture and recording video to the desktop using AIR. I would like to know how that can be done and how the recorded videos (in FLV format?) can be uploaded to a server by the AIR application. Thanks, Gilbert
