"Embed" a font at runtime about adobe-runtime-support HOT 3 OPEN

You can now load in a TTF file at runtime, and then use this to render text via the Flash Text Engine classes, see the update to FontDescription:
https://airsdk.dev/reference/actionscript/3.0/flash/text/engine/FontDescription.html#createFromByteArray()
(It actually seems to work with font files that have true-type outlines too..)

But to do the same for TextField and 'normal' Font objects, we would need to adapt some Java code from the Adobe build tools (that we don't (yet) have source code for) so we are hoping to provide this but it's not going to be soon..

TextField isn't going to help with RTL languages though .. all of the complex rendering with combining of glyphs and handling accented marks etc, all sits within the text component used by Flash Text Engine. So for any advanced stuff, it may be that you won't be able to solve it just with TextField.

But yes .. in terms of that font embedding, we will see where we get. It's actually just a translation that's required from the outline mechanisms that are possible within TTF files, to the 'shape' definitions that are used in the SWF files for non-CFF embedded font data. All open source / open spec but probably a very large job, hence trying to get the Java source code that's used within the compiler so that we can translate that to C++ and put it in the runtime..

It's sad to say that the Flash Text Engine is too complex to use compared to TextField. To use FTE with TextField-like features, I need something like the Text Layout Framework (that has been deprecated). I'm building a framework to implement the Adobe Spectrum to AS3. I had spent over 1 month tried to build something like the TLF but had to give up. Then I came back to the old friend TextField and successfully implemented almost all features I need (undoable, skinable, text coloring...) using a wrapper. Now everything is ok except some issues with the font embedding, RTL languages, paragraph spacing, superscript, subscript (that I can't do by myself). Hope to see font embedding on TextField in the not too far future...

Thank you!
