Flex :: Encoding For RTF Text - Does One Exist
Nov 2, 2011
I'm wondering if there is an encoding like UTF8/16 that can account for characters that are bold, italic, underlined, and super/sub-scripted? If not, is it under consideration by the powers that be? Reason for the question is that I have a large excel file where many cells contain rtf text such as italics, bold, superscript; and I need to access the information on a row-by-row basis. I know I can save the file in html or xml, but I would like to import the data into MySQL - keeping the formatting - and then being able to access the data a row at a time.
I've considered using Markdown or Textile, but that means a whole lot of time changing each cell - we're talking about 5,000 records. Also, I want to continue to use Flex and I'm not sure if Flex can display html formatted text in their text controls because of their their text engine...

Some text (or html) document from web is not encoded as UTF-8, so I want to convert encoding of text document to UTF-8. Do you have any clues for dealing with text encoding?
And I found that, when application draws element with encoding-broken text (such as "º ½¾ ±"), the application is often killed with alert dialog "adl quit unexpectedly". How can I make my application more endurable.

For example if I had an input field and i could not allow the characters like <space> and ony <underscore "_"> how would I do this??
I am guessing you would have to somehow check through ecach character to see if it was a " " with an if else statement.. but that would take forever.. so.. =S

Does any such control exist out of the box for Flex? I see people say things like "EPUB is just a zip file of XML and HTML files, so it shouldn't be too hard"... yeah, I get that... but if such a control exists, I wouldn't have to write it.

I have made it this far with much help and all was working well until the xml changed. Sometimes the c_Result node does not exist and my c_points text box returns 'undefined'. I have tried if(c_points != undefined){ etc which works to a degree but I don't know how to make the text box blank if the node doesn't exist and load the c_Result node if it does.

I have a flash app that needs to download a file, whose name contains UTF-8 characters.
Internally, the filename is read from a UTF-8 XML file, e.g. "my filé.pdf". The code goes something like this:
url = get_filename_from_XML();
req = new URLRequest( url );
ref = new FileReference();
ref.download( req );
The problem is that the URL is encoded in Latin1, i.e. the é is encoded as %E9 instead of %C3%A9 (according to FireBug). How can I get Flash to encode the URL correctly?

I am trying to encode certain values that I receive from keyboard event. Basically I want to check if a certain key combination has been pressed or not, so for that I am converting the key codes into sequence/pattern and store it in an object and a value(function) against each code sequence. Now I have to use four bytes and in first byte(MSB) I've to store shift, alt, ctrl respectively and in the last(LSB) I have to store the keycode of the key pressed.
Here is the code:
private function m_encodeValue(key:String, Ctrl:Boolean = true, Alt:Boolean = true, Shift:Boolean = false):uint {
var encodedValue:uint;
encodedValue = uint(Shift) << 2 | uint(Alt) << 1 | uint(Ctrl);
encodedValue = encodedValue | (uint(key.toUpperCase().charCodeAt(0)) << 24);
return encodedValue;
}

I want to post data to a URL on my server from a Flex app. I am using the following
UrlParam = UrlParam + '&name='+ name.text + '&business=' + buisness.text; navigateToURL(new URLRequest(UrlParams),'_self');
The problem I am having however is that if I enter a business with an ampersand ("A&b.com") then the name does not send. Does Flex have anything out of the box to do the encoding from & to %26?

I need to compress video image data (lets say a display object) in AS3 to a Byte Array with high compression at runtime. Framerate only needs to be around 5 but 1024x768 video needs to go to < 40 Kilobyte per Second without the quality being too bad. I wrote a custom encoder and got it to around 80-100 Kilobyte per Second for 1024*768 which still is too much and I don't see a lot of improvements to be mad to my encoder.
Using JPG or PNG Encoder gives way higher KB/s. Is there any open source way to to decode and encode video in as3 at runtime ? E.g. a H.264 as3 encoder and decoder ? Or other codecs? Or maybe a C# source code of h.264 encoder and decoder ? I think I could port it to as3. Doesnt need to be h.264, just something with good quality when running at 5 Frames/Sec and 40 Kilobyte...

I embed a text file into my Flex project and read its contents using code like this:[code]The contents of the file is abc. The problem is that the string loaded from the file is not comparable to other strings even though when printed or viewed in the debugger (in FlashDevelop) it seems to be perfectly fine.[code]How do I convert it into a proper string? I tried to use the string methods such as substring to create a copy, but that does not seem to be the solution.

I have a very general requirement that seemed very simple: Step 1: Load a new external JPEG image into a MC with a string var encoding a string caption in the URL link (VALUE="../fadeTest.swf?someTextVar=TestCaption") within the EMBED / OBJECT sections. I know how to do this and it semed to work fine. STEP2: When the JPEG is loaded I would like the substituted Text to Fade In over the JPEG. The JPEG should also fade in before the Text. The fade rate should be programmable.

Internally Flash obviously keeps a list of the primitives drawn using Graphics so I wondered if you have many such primitives in a Sprite, can you re-position/remove/alter individual items rather than clear and re-draw everything? Or is this deeper into the bowels of Flash than you're allowed (or recommended) to go?

I'm playing around with a messaging type of application. Does anyone know how, or of any tutorials on to "appending" html text to text areas in flex and flex mobile projects? And specifically how I could take that and basically "append" a sprite inline to the text when i need to? Something simple like:Username: some text right here!So, Anyone have any experience "appending" sprites or simple text formatting?how to solve these issues!EDIT:Based on an answer below it was sugguested that it's as simple as...textAreaInstance.htmlText += "<b>Username:</b> some text right here!";But its not. you can't do .htmltext with a text area. you can on a text field, so i tried
var TF:TextField = new TextField();
TF.width = 200;
TF.height = 200;

I've been using Flash Video Encoder for quite a while now and never had a problem encoding flash from wmv. But in the last week suddenly encoding crashes on ever attempt. At first I thought it was a change in the format of the video that was being introduced, but then I tired videos that I know that I've converted previously. They crash too. I've also tried on 3 different computers, that have all had success in the past.

I have some German content which contains an umlaut (ü). This content is being built into an XML file. I then have a flash file which uses the xml to build a coverflow. My problem is that the 'ü' character is not being displayed in the coverflow. I've made sure the xml is encoded correctly, as you can see from the snippet below:
<?xml version="1.0" encoding="UTF-8"?>
<artworkinfo>
<albuminfo>
[code]....
As you can see, the umlaut is in the albumName element, but when that text displays it simply misses out the 'ü'. I've added a bunch of encoding groups to the text element in the coverflow file, as well as specifically adding the 'ü' in the 'Include these characters' element. I'm stuck for how to get this to display.

So I have recently created a Tshirt design application where a user can draw on a tshirt / add text / upload images. Though I am having a few problems. Problem #1: Using the pen tool I can only allow users to draw and reset the drawing using the graphics class, no idea how to create an eraser tool
Q1 - Is there any way to create the eraser? Problem #2: Once a user saves the shirt it is later encoded into a JPG or PNG With no way of editing the shirt in the future.
Q2 - I thought of saving the locations of the shapes / items they uploaded onto the shirt and colors and later re-creating the shirt once loaded. But ran into one problem that is I cannot save the drawing they did using the pen tool, only the location of the objects (MC's) is there any better way to creating this?

i'm writing simple image editor. I want to allow user to change contrast, brightness ect and save file as jpg. I got 2 problems.
1. I apply filters to bitmap and when I save it, it saves only original image without filters.
ActionScript Code:
var bitmapData:BitmapData = Bitmap(source_image.content).bitmapData;
var bmp:Bitmap = new Bitmap(bitmapData);
bmp.filters = combineFilters();
combineFilters function gives a set of ColorMatrixFilters to change contrast and other stuff.
2. When I encode a JPG with a as3corelibrary it makes it very slow (over 20 sec for img) and freezes app. Is there any way to aviod this?

I am experimenting with video using the alpha channel capability of the FlashCS3. I followed the tutorial on the gotoandlearn website on how to create chroma keyed video. I exported an avi video file having removed the background. Ive used Flash video encoder for VP6 and flash player 8 with encode alpha channel ticked. However my swf is not showing the video, just a white blank where it should be. It puts out the audio only.
This is the log file.
