.net :: Detecting Glyphs Occurrences In Any Fonts
Oct 27, 2009
I'm writing a small .NET application that can produce SWF files, and I need to support Unicode fonts. I don't know the things on it and font rendering well, so I understand that I've made some blunders while writing my application: many fonts installed on my Windows don't support Unicode characters so I can see hollow squares only instead of the glyphs. My supposition is using of proper font substitution while rendering the SWF files that could contain embedded glyphs. First of all, I must determine whether a glyph is present in the necessary font.
I've found a partial solution of such test here, though it doesn't seem to be the thing I want to achieve because the sample operates for Unicode ranges only. But I've paid attention on Windows' Charmap application: it can hide missing glyphs. I tried to explore how charmap does the check with Dependency Walker to analyze its import table, but I didn't find anything instead of some GDI++ font functions. It could be a WinAPI or .NET 2.0 (not even .NET 3.0)

how to use the IDE for selecting which glyphs you want when embedding fonts, but is there a way to do it in code when you've created your text field entirely with code?The pages on embedding fonts using code in the Adobe support area don't seem to mention glyphs. Do you add something after... myText.embedFonts = true;

My app does the following:enumerate fonts installed on the clients machine, and populate a dropdown list with them present a s:TextArea with special characters (like äöü)update the TextArea's font family to the one selected in the dropdown After it updates, there seems to be three possible results: the correct glyph, a blank space, or a fallback glyph in a device font (seems to be _serif, though the CSS style is _typewriter). My goal is to programmatically detect whether a device font supports all the glyphs in a chosen user font.
I have tried getBounds on various children (to detect 0 width, etc.), getting info about atoms, and comparing fontFamily for a correct glyph against fontFamily for a blank or fallback glyph. For formatting changes that dispatch a UpdateCompleteEvent or CompositionCompleteEvent, i am always doing my checks after it completes.

I've been trying to wrap my head around this for some time now, but haven't been able to come up with an elegant solution. The problem: I have a string with different characters ("ABDDEEDDC") and I need to know which character occurs the most.

Is there any way to enumerate the glyphs available in a font? I know you can check if a specific glyph is available via Font.hasGlyphs(), but I'm looking for the opposite direction, something like a enumerateGlyphs() method would do if it existed. Sadly it doesn't seem to. Is there a workaround or known way to determine available glyphs?

I'm doing a project for an education company that requires the use of a cursive font. The cursive font has many glyphs so that the characters can connect with each other. There are several versions of each letter so that they connect correctly to whatever letter is beside it. The glyphs work fine in InDesign and Illustrator, but not Flash. I tried embedding the entire Glyph set but that doesn't work.

in many programming languages there is this great idiom that lets you use a hash to count occurrences of items. Eg in Perl, suppose you have a list of students and you want to see how many of each name you have (2 Bobs, 1 Jeremy, 22 Aidans etc):
my %uniqueNames;
for (@studentNames){ $uniqueNames{$_}++; }
# print it out[code]....
So you can do this in ActionScript 3 of course, using the Object.The problem is NaN. If you try to autocreate and autoincrement a key at the same time, you get NaN, and the whole thing breaks down.Sure, you can use a conditional to test whether the key exists, and then autoincrement it, or set it to one if not, but that's ugly.
studentNames[name] = studentNames[name] ? studentNames[name] + 1 : 1; // shudder

Is there anyway to count the number of occurrences of an element in an array? E.g.
array = (a, a, c, h, a, h, g, j, j, j)
//Number of times each element appears in the array
a=3
c=1
h=2
g=1
j=3

A project I am am working on has an extremely strange font problem. We have completely unpredictable glyphs missing on Mac compilations inspite of correct font embedding and correct font installations on the machines. Here is some of the context:
1. The Font is a custom truetype font which belongs to the client.
2. We are working on CS5 on the Mac, and CS4 on PC.
3. We are using classic dynamic texts, assigning striungs to the text attribut (not to htmlText). However the probel also occurrs with other classic text modes (single-line, multi line, kerening on or off, etc)
4. It is not predictable whether the glyphs of the font will show or not on the Mac CS5 compilations or not.
5. The issue does not seem to occurr with standard fonts like Courier or Helvetica.
6. Compiling on CS4 on PC works correctly.

I save my (embedded) fonts in an external file (fonts.swf) that gets loaded at runtime. Pretty standard. I also use a bunch of UI artwork generated in the Flash IDE. Some of this artwork contains static textfields (thus, not proper TextFields that can change. Just frozen glyphs). Here's the problem: if I use the same font in any static textfield and then embed that same font into my collection of runtime fonts, the runtime font will refuse to render. It's the same effect you get if you set a textfield with embeddedFonts=true to use a font that isn't embedded. If I change the static textfields to use a different font, the runtime fonts work just fine.

Edited Short Version:The Adobe Flash docs list a property embedFonts on TextAreas:
A Boolean value that indicates whether the font specified in fontFamily is an embedded font. This style must be set to true if fontFamily refers to an embedded font. Otherwise, the embedded font is not used. If this style is set to true and fontFamily does not refer to an embedded font, no text is displayed. The default value is false. Regarding the "If this style is set to true and fontFamily does not refer to an embedded font, no text is displayed" statement: How can I detect in ActionScript when this scenario happens?
TL;DR Original Version: I have a flash application which loads external .swf files containing embedded fonts, so that these fonts can be used within the main application. We're accomplishing this by using the following ActionScript code on anything which uses custom fonts:

Right I can upload the font to the server.But the only examples I can find - require registerFont(Verdana);Which means I'll need to create a new SWF with the new font embedded and reupload to the server. I need an automated way of doing this or perhaps something different altogether?

In Actionscript and Adobe Flex, I'm using a pattern and regexp (with the global flag) with the string.match method and it works how I'd like except when the match returns multiple occurrences of the same word in the text. In that case, all the matches for that word point only to the index for the first occurrence of that word. For example, if the text is "cat dog cat cat cow" and the pattern is a search for cat*, the match method returns an array of three occurrences of "cat", however, they all point to only the index of the first occurrence of cat when i use indexOf on a loop through the array. I'm assuming this is just how the string.match method is. I want to find the specific indices of every occurrence of a match, even if it is of a word that was already previously matched.
how the string.match method is and if so

I've recently had to format my computer and now having a problem with the flash actionscript window: the actionscript text looks like bold, or in a different font. The problem is that when I search for something like "flash" and "fonts", no matter which other words I use, always comes a lot of things about fonts for flash files, or for flash embedding fonts, but never for the program itself. Wich font is missing in my system that flash CS3 needs?

I have embedded a swf into a another swf using Loader & URLRequest methods, which work fine.
To detect whether the swf has ended I define it as a MovieClip. Then I check (using an ENTER_FRAME event listener) if the current frame is equal to the total frames. This works fine for a swf with a simple animation in the timeline (what I was testing on). However:
If I use the same method for a swf with a streaming flv inside it, it gives me a runtime error: Type Coercion failed: cannot convert Play_Intro@20d71b51 to flash.display.MovieClip.
If I define it as a Sprite- it plays without any errors, but then how do I detect when the swf is at the end?

I am trying to implement paged recordsets in a datagrid and since I've not been able to find a way as a standard feature of as3 (recordset type was not provided in as3) - I'm cooking my own.The only problem I have is knowing when additional records should be requested. I need to be able to tell when the scroll bar or other method is used to scroll the datagrid down to the end (or near the end).

I'm trying to make this fluid preloader that uses tween classes to change the size of the bar instead of just using something likegotoAndStop(percent)I have the tween class working but need a way for it to detect the change of the percentage variable. Here's what I'm trying to get it to do:Current percentage is at 55, this is set as the "currentPercent" variable. It suddenly jumps to 65%, the "currentPercent" variable would change to 65 while the "prevPercent" variable would stay at 55 so the tween class could have a beginning and ending value.

So for a site I would like to have 2 swfs, mainContainer(just has preloader) and index(contains all assets)
This will allow me to have a nice, 0%-100% preloader.
However during development I will just be publishing index. So to start my chain of functions, I have my document class for index like this:
ActionScript Code:
public class index extends MovieClip
{
var path:MovieClip;
[Code].....
However, this will fail when index is loaded in to mainContainer, because the code gets run before I addChild on to the mainContainer displayObject.
So I need a way to detect whether index is loaded or not in another swf. How's that possible?? There doesnt seem to be an easy way.
