I saw that you can embed meta-data into images very much like you can in mp3s, here.
Can someone point me to a tutorial of how to embed and read this sort of information w/ photoshop and flex together? I really wouldn't know where to start... Tried googling but I'm not sure I have the right keywords down.
I am doing an Actionscript 3.0 project which involves introspection. I am wondering if there is a way to get all the classes within a given package structure.

I am building a flash panel that reads metadata from a .fla when it is active in the Flash IDE. This panel is also storing metadata in the .fla and that is no problem. What is problematic is that I do not know how to stop the event listener from listening for onDocumentChange.
I want it to listen for it as long as it is open, but when it's closed it should clean up after itself because trying to read metadata every time a new document is selected is not a very nice thing to do.
I have tried to listen for all kind of events in the panel to detect when the user closes it, but with no success.
I have a video that displays closed captioning inside Quicktime player (it was embeded to the file's metadata).I've tried pulling that information out as if it were conventional flash-friendly metadata, but that doesn't seem to do the trick.
View 5 RepliesI would like to read in an FLV's cue point names and times and load them into an array which would have the form: [[cueP0, 0.0], [cueP1, 3.2], [cueP2, 6.8], ...]. I wou ld like to populate this array *before* the flv plays through for the first time, so I need to do this when the flv's metadata is first read in.With rom some of the posts in this forum, I have figured out a way to retrieve the cue point names and times (see the following code), but I am unable to "grab" these variables to populate an array with them.
//the function called when flv first loads
var cuePointNames:Array //an array I created just to see if I can populate it with cue point names from metadata

overriding clone() while creating custom events?I read in the Flex cookbook that we need just in case we want to redispatch this event. Does this exactly means that when we want event to be bubbled up the display hierarchy , at that time our custom cloned event should be dispatched and not the Event object.
second - whats the need of metadata tag -
[Event(name="modelEvent", type="com.abc.data.model.ModelEvent")]
public class LoginModel extends EventDispatcher
I understand we need to extend EventDispatcher in case we want to dispatch evnet from class.. but In what cases i would need to specify the MetaData TAg
Third is.. If i write -- "dynamic customEventClass extends Event".. Is there any use of Dynamic i can make?
I know that it is possible to add swf metadata to the compile command as a command option, but I can't find any documentation on how to access these metadata within the actionscript during runtime. We're trying to add a version number to the swf during compile time and then somewhere in our app we would retrieve it during runtime, here is the command example to add the description metadata.
mxmlc -description "version 1.2.3"
I know the swf metadata is used by search engines and other utilities to gather information about the SWF file, but surely you should be able to retrieve them in the actionscript during runtime?
I'm trying to embed a font in Flex and the code I'm using looks the same as the example, but throws an error. This is the code I've written:
[Embed(source="data/posca_mad_thrasherz/posca_mad_thrasherz.ttf",
fontName = "fontGraffiti",
fontWeight = "bold",
mimeType="application/x-font")];
private var funFont:Class;
But I get the error, "Metadata requires an associated definition." I can't seem to get rid of it.
I have a situation where a simple query against a table is returning incorrect values in Flex, but not in other GUI front-ends to SQLite.
select title from ttl where ttl.ttl = 140 // ttl is also the column name of the PK column
is returning the title that belongs to the row whose PK = 1400.
ttl.ttl is defined as int datatype.
Again, the problem manifests itself only in Flex, not in other GUI front-ends to SQLite, which are returning the correct title value.
I have something like
public class Controller {
[Observer("fetchEmployeesEvent")]
public function fetchEmployees() : void {

What language construction can be used to make a compile time checking of Array elements type when the Array is a function parameter?[code]Here we've marked the returned Array as one containing elements of type string.Is there a way to mark the parameter variable as an Array containing elements of certain type?I'm specially interested in the Array collection. I'm aware of the vector collection but I have reasons not to use it in my case.
View 3 RepliesI have an actionscript, which makes a dynamic image wall. It gets parameters from FlashVar and changes the width and height dynamically.
When I use
[SWF(width="584",height="290")]
It's fully centered, but when I remove it, it's appear ~+50px from left. How can I set dynamically the SWF metadata or what I need to set for the correct view?
Top of the picture with SWF tag and the bottom is without SWF tag.

View 2 RepliesI am just just curious as to whether the [Bindable] metadata tag in ActionScript 3 can only be used within the Flex framework, or can it be used in "regular" ActionScript projects where Flex isn't used?

View 4 RepliesI am working over a program that needs to extract meta data from music files in different formats. It was easy for MP3 format, but there is nothing for other formats.I made a research, there is a lot of software for extracting meta data - but no source code or algorithm. There are open source projects, they use their own libraries, but I was not able to find something for Flex (Action Script)

[Code]...
If you run these, you'll notice that the MXML-component can't hear the event. The question is simple, is there some way of getting the Event-metadata tag to work WITHOUT extending EventDispatcher? I would like to keep this class independent and use object composition as much as possible. And no, I don't want to use ActionScript addEventListener in the MXML-file. It doesn't tell the developer anything like good old Event metadata tag, and besides, that is not the point of this example. :)
I'm studying a demo code and it seems to me that an instance of a class is never instantiated, in particular I have this line:

I am changing the flashvars variables v1=value&v2=value ect then after the flash movie runs I am changing the variables externally by javascript, so far so good.when flash first loads it reads the vars correctly.when I try to read them ( after the change ) it keeps reading the old values.[code]everything works except I cannot seem to read the changed FlashVars.

I want to use the Event metadata tags to show what types of event my control will dispatch. The syntax looks like:
<fx:Metadata>
[Event(name="eventName", type="MyEvent")]
</fx:Metadata>
It seems like a best practice in Flex/Actionscript to define static variables that define event names like so:
public class MyEvent extends Event
{
public static const EVENT_NAME:String = "eventName";
// Other stuff..
}
It's a great practice since the event name can change easily and not have to be modified throughout the code. So my question is: Is there any way to use this static const in my metadata event tag? I can't seem to do something like this:
<fx:Metadata>
[Event(name="{MyEvent.EVENT_NAME}", type="MyEvent")]
</fx:Metadata>
Am I just ignorant of the proper syntax to do this, or is it impossible? Seems like it's just asking for hard to find bugs if someone decides to change the const since it is not strongly typed here.

View 1 RepliesI need to make a small app accessible to screen reader.I'm managing to make buttons accessible, but I would also like to have a section of text accessible by screen readers so that users can hear what the text says.
I can't seem to work out how to do this.. I've tried various text controls and set them as focusEnabled, tabEnabled, i've set the accessibility* attributes too but it never seems to work, I cannot tab to a text label and hear the content.
I'm honestly a little new to accessiblity in Flex so apologies if i'm missing something obvious.
I have managed to import and read a PDF using the CF Proxy for Actionscript: [URL]After all my trouble there, the precious form filed information that I was looking for was not there in the PDF info object. GRRRR. So I am back to looking for a way to do this with CFC's or CFM's or PHP.All I want is this:
Read the PDF from a Flex app.GET the form field information.WRITE a new PDF with the form field values.I have found so many close but no cigar options ... and I have tried so many that failed. There are so many free PDF this and that out there. But Adobe seems to reserve the real functionality for themselves. All the free options don't seem to have access to the form data?
i have seen almost all relevant threads on almost whole internet. and i m still confused..i m working on a drawing app ( flex / air ), 1- where user loads image file,(bitmapdata > bitmap > movieclip base layer)2- add layer ( new sprite > movieclip "second object in display list")3- draw on this sprite ( graphics.draw circle / etc, lot of other details etc)4- usr can add more layers etc, name layers etc ... all sprites are of same size as bitmapQ1. now i wanted to save this main movieClip (part of UIComponent ) as swf file. so user can read again and continue work. almost like i do with photoshop.
comment: i know it sounds too generic, to ask such detailed thing. so please be patient..i have been fiddling around with byteArray. and Air File Object,flash.net.fileReference etc..Q2. (main question), i don't want to convert drawn sprites to bitmapdata and then do bytearray. ( in my mind) it will convert everything to pixels, which i don't want.Q3. is there some auto magical line which will do everything..(save drawn vectors / shapes) in sprites as is?? (less chances). if i can read swf as movieClip, i can check sprites for layers and everything else... problem is writing this to disk as swf file.
