Re: [flexcoders] Embedding fonts at runtime

Wed, 30 Aug 2006 12:54:08 -0700

I figured out how to use the textformat object.  The textformat object does actually work, but a TextField will only retrieve the embeded font if it's parent has previously been sent set the font as a style.  So for any component that uses a UITextField, set the fontFamily style of the parent UIComponent to the newly loaded font and then the UITextField should be able to use the font even if fontFamily is subsequently reset.  I have no idea why this works, so there may be some improvements to this method.

One addition to this, which is that we always include the space character when you specify the unicode range.  I'm not sure the original reasoning for this, but I just noticed it in the code.  Also, you can specify multiple ranges, separated by commas.  -Brian

Yes, this is possible:
 
[Embed(source="Arial.ttf", fontName="myArial", unicodeRange="U+0041-U+005A" )]
public var myClass:Class;

Awesome! I'll definitely have to check this out.

On a related note, I wonder if its possible to embed fonts with a
specific unicode range via this syntax.  It doesn't appear to be.

[Embed(systemFont='Symbol', fontName='mySymbol',
mimeType='application/x-font')]
var myFont:Class;

I know you can use @font-face, which appears to automatically generate a
variable in the class, but its not a consistently named variable. I am
sure a utility function in the class could be used to ferret out that
variable name.
