Actionscript 3 :: Get Per-character Advance From Flash's Font Engine
Jan 6, 2010
I have a project coming up where I'll be rendering text paths on a circle; the text has to be dynamic, so I can't just bring in a precomputed set from illustrator. Now, laying text on a circle ought not be too hard, I'll do it per character with per character rotation. The trouble is, I can't seem to figure out how to get per-character advance from flash's font engine. It's 99% probable that I'm just overlooking something obvious. But as far as I can tell, the only way to get flash font metrics is via flash.text.engine.FontMetrics which ostensibly is per-font, not per-character.
A fallback that I'm not looking forward to implementing is pre-computing per-char advance on my own ( since this project will be using embedded fonts known in advance ). I've got ObjC code lying around for generating glyph maps for opengl, so I could generate that data offline and make it available to my flash code ( probably as static constants or some malarkey ).

In my application I'm using a custom embedded font for English (Helvetica New) which does not contain characters (glyphs) for chinese unicode range. In the application, wherver chinese characters are avaiable they are not displayed (suppressed) since they are missing in the custom embedded font. How can I make the flash player to use a fallback system font for the missing characters? And the fallback should be for the missing characters alone. For the Engligh characters it should use the embedded font.

I am using Flash Text Engine's TextBlock & TextLine to display text. However, I found that some font make TextLine calculate height incorrectly. Here is my sample code:
package users
{
import flash.display.Sprite;
import flash.display.StageScaleMode;
import flash.events.Event;
[code]....
which means TextLine.textHeight, height, totalHeight, and result from getBounds give the same value, roughly 57.6 pixel So, my question is, how can I get the actual text height?Please don't tell me not to use Swansea. So far, I have tried 5-6 different fonts and only Swansea give me this problem.

I am making a game and I am trying to decide what is the best practice for exchanging damage between two objects on the screen. Should the damage be passed directly between the two objects or should it be pass through a central game engine that decides the damage and different criteria's such as hit or miss or amount dealt.

When the files are downloaded to your computer there are several file folders included. Some are for pictures and there is HTML as well as the SWF files and the INDEX. In very short order I determined that you could simply replace there pictures with your pictures and even change the text on the buttons as well as the body of the site. It seemed very painless. We are now down to just one issue that I cannot figure out. On the main page there is a place on the page for the company name. I went into the HTML and changed that which worked fine.
My issue is that she already has a predefined font for her company. It is Trajan Pro. I cannot find anything in the HTML that has to do with the font.However there is a folder included in the download which is entitled "fonts". Within that folder is the various fonts used in the website. how I can change the font that is being used?
PS -- There is a folder full of Photoshop images which are basically the pages of the site. They have many layers. I tried to change the company name and font in Photoshop but it had no affect.

This is a rather advanced problem but apparently I'm not the only one having it.So far I've been using external font loading in all my projects. A Tahoma.swf with a Tahoma Font library item and basically two lines of code:ActionScript Code:import flash.text.Font;Font.registerFont(TahomaSmooth);As soon as I load the font in my application it's ready for use. This is Jesse Freeman's method, in case it looks familiar.The problem is Flash CS4 doesn't embed polish fonts. And clients dnt lke t read tet that hs mssng chrcters. Unfortunately for anyone who isn't english Adobe didn't forsee that people might actually want to specify the character set when embeding Fonts. This strikes me as odd, as supposedly the whole font was supposed to be imported, at least that's how it originally worked, AFAIK.

I have created a class which will use an embedded font to dynamically generate a bitmap font at run-time. So far it works well except that I have a minor issue with character spacing.
In the image below the first line is an actual TextField and the second has been rendered using the generated bitmap font.
If you look at the word 'fox' or the 'ed' of the word 'jumped' you can see that the letter spacing looks a little bit odd.
Are there any alternatives to the TextLineMetrics class which will give me more accurate character metrics?
UPDATE :
Text rendering quality using the new Flash Text Engine :
UPDATE 2 :
By chance I have eventually found the solution :
The first problem was the antiAliasType property which was set to AntiAliasType.ADVANCED. Although it produces higher quality text it also causes TextLineMetrics to return incorrect widths for characters.
The second was that it had to also be rounded up (using Math.ceil) to the nearest pixel and not down.

I have a text field (old-style, non-TLF) with the following HTML text:[code].....
The font Optima is embedded, and I've selected embed all glyphs.What I'm getting rendered to the screen is as the image below, with a random i + umlaut character in place of the bullet.Is this a problem with Flash or is the font file somehow missing the bullet character, and does anyone know how I can fix this issue, preferably without having to move across to TLF text.?

I am tasked with created a site that handles Japanese characters, and am looking for any insight you can offer for this.My main issue right now is the size spike the site will get if I embed a font like "Arial Unicode MS" with the Kanji character set which has 3174 glyphs. When I compiled an fla with only a textfield and these Japanese characters embed it stands at 731k. So I am looking for options to either eliminate the need to embed the Kanji characters or find a way to limit the number of characters needed to handle the Kanji character set.
1. Which fonts if any come pre-installed on Wins & Mac that natively handle Kanji characters.
2. If there is such a font for Win & Mac does this mean I don't need to embed the Kanji glyphs for the font in a swf, and can be sure any user viewing the site will be able to see the Janji characters, because their OS already can handle displaying Janji characters. For example if I go to a webpage on the internet that has Japanese characters I am able to view the Japanese characters, is this because the browsers themselves have these fonts embedded or is it pulling from my OS to display the Japanese font?
3. If I do need to embed a font to handle the Janji characters do I need to include all 3174 glyphs to cover all possible English equivalents. I read that you can specify a unicode range for a font, believe this only works with CS4 though. I don't know much about unicode ranges let allow the ranges I need for Japanese characters.

I did the tutorial for "create a full flash site" under flash mx advance. I did everything right and it worked. Ok here is what i want to somebody to help me out.
The action: on (release) {
_root.contents.loadMovie("locations.swf");
}
because when i extracted the zip file it had only the different swf. files and the main file where they were going to be loaded. What i am saying is do all the swf. files have to have some connection to the main movie where i am loading the swf. files in order for it to work or it doesn't matter. so what am trying to say is i could have any swf. file and use that action to my main movie even if has nothing in come and it will play it.

I'm trying to embed a font in my project by using url("font.ttf") rather than local("Font Name"), but it doesn't seem to pick it up. The font in question is called "Gotham Bold". When i view the details of the font, the font weight is regular, however when i use local("Gotham Bold") in the css i have to specify fontWeight: bold or else it wont pick it up. But when I use url("folderGotham-Bold.ttf"), and specify fontWeight: bold, it says that font weight is not found for that TTF. If i remove the fontweight, there's no errors, but the font is not applied to the text.

I am working on a as3 project in which the user select a font from Combo Box and that font SWF should be loaded Dynamically and then i need to change the font of the Dynamic text field.
I have swf font files downloaded from [URL]
My question is that how can i load the font swf dynamically from server and add them to the library and how can i use that swf to change the font of dynamic text field.
if there are embedded fonts in library the i can access them using this- --
var fontList:Array = Font.enumerateFonts();
for( var i:int=0; i<fontList.length; i++ )
{
trace( "font: " + fontList[ i ].fontName );
}
But How to use dynamically loaded Font swf as a font type.

I have a swf A, which contains no font.If I download into it the swf F1, which contains few characters of Arial, then I'll have the arial font embed into A, no problem with that.But if, then, I download the swf F2, which contains other characters of Arial into swf A, will I be able to use all the embed characters font, only the F2, or only the F1 ?I'd like to have a link to somewhere where this is explained, even in very technical terms : I wasn't able to find one.
EDIT : After few tests, it seems that the player replace the loaded font... How can I merge them, then ?

Is it possible to embed a font in Flash and have it displayed as though it was a device font? In other words, can embedded fonts be aliased?Using the bitmap-text option doesn't work, Flash tends to screw up a lot of the character spacing. I haven't found any pixel fonts that mimic Arial, Verdana and Tahoma accurately. Setting the stage quality to low does alias the fonts but they become fragmented.Using device fonts is an option but, as far as I understand, some browsers/operating systems will take it upon themselves to anti-alias the text.

How the heck do you Kern in Flash CS5 while using the new TLF text engine?
There's no letter-spacing control and the keyboard shortcut doesn't work.
I'm not interested in auto-kerning. I'm looking to tighten up large text like headlines and logos and stuff.I'm starting to suspect it can't do it.
