在 Flex/AS3 中动态加载字体
虽然有多种方法可以将字体加载为 swf 文件，但我更关注的是加载字体文件本身的方法，假设用户上传了字体文件，我如何在应用程序本身中使用该字体文件？
谢谢， 费萨尔·阿比德
While there are ways to load fonts as swf files, what I am more looking at is a way to load the font file itself, say the user uploads a font file , how can i use that font file in the application itself?
Thanks,
Faisal Abid

不幸的是，我很确定这是不可能的，至少以任何正常的方式都是不可能的。
您无法加载 ttf 文件的字节数组并将其传递给 Font.registerFont()，需要调用该方法才能使用该字体。
然而，尽管我不具备做到这一点的所有知识，但我知道这绝对不是不可能的。
正如您所说，字体可以从 swf 加载，并且 swf 可以动态创建为 byteArray 并加载。
我不知道这是否适合您，我'我不确定这到底有多难。
我会阅读此处提供的 swf 文件格式规范：

然后研究空swf的字节码，然后研究嵌入单一字体的swf的字节码，并找到字体的数据在哪里，这就是必须用用户提供的字体替换的内容。
我想知道嵌入 swf 中时是否所有文件内容都未受影响。 在这种情况下，实际上只需将字体数据插入模板 swf 的正确位置即可，这应该不会太难。 但它可能比这更难一点，而且我怀疑它也会被压缩......
如果你用谷歌搜索，可能会有一些关于以编程方式创建 swf 的信息。
抱歉，我无法给你一个更方便的答案 =)
Unfortunately I am quite sure this is not possible, in any normal way at least.
You can't load in a bytearray of a ttf-file and pass it to Font.registerFont(), which needs to be called in order to use the font.
However, even though I do not possess all of the knowledge to do it, I know it is definitely not impossible.
As you said, fonts can be loaded from swf's, and swf's can be created dynamically as a byteArray and loaded in.
I don't know if this would be an option at all for you, and I'm not sure how hard it would really be.
I would read up on the swf file format spec available here:
http://www.adobe.com/devnet/swf/
Then study the bytecode of an empty swf, and then the bytecode of a swf with a single font embedded, and find where the data of the font is, that's what has to be replaced with the font supplied by the user.
I wonder if all of the file-content is untouched when embedded in the swf. In that case it's practically just a matter of inserting the font-data in the right place of the template swf, which shouldn't be too hard. But it probably be a bit harder than that, and I suspect it gets compressed as well...
There might be some info about creating swf's programmatically if you google around..
Sorry I couldn't give you a more convenient answer =)
