if not how to build cff table with the glyf and loca table of the ttf font in as3...

thanks

Simon,

makeOTF can't convert between font formats. There's no FDK tool that you can use for that.

Also, keep in mind that if these are fonts that you licenced, you should make sure that the license allows you to do such conversions.

hi Miguel,

i work for a book editor who have built the font licence for all support (print, web...), do you know a way to create the cff table with the glyf and loca table ?

thanks

You'll need to use a font editor or a font converter app.

i need to do that  in runtime with as3... it seems to be hard to do that in pure as3 code but i can use a exe file and communicate with it with NativeProcess class, but i can't find a font converter standalone exe... do u know one ?

thanks

I guess I didn't quite understand what you're trying to do.

You want to convert a whole TT font to OT/CFF font at runtime? Why do you need to do that?

TLF supports both TTF and OTF. What it doesn't support is Type 1 fonts.

tlf dont support ttf because ttf doesn't have cff table, tlf need a definefont 4 font definition with the cff table, otf (opentype) have cff table but ttf (truetype) doesn't have this table, the glyph is describe in ttf with glyf and loca table....

I'll admit that my knowledge on DefineFont4 and using fonts in Flash is a bit rusty, but I think you're wrong. I'm 99% sure that TLF supports TrueType fonts.

Have you considered embedding the fonts?

Here's a code example: Embedding fonts in ActionScript

The part of most importance to you is probably this one:

[Embed(source='../assets/MyriadWebPro.ttf',
fontName='myMyriadFont',
mimeType='application/x-font',
embedAsCFF='true' )]
// You do not use this variable directly. It exists so that
// the compiler will link in the font.
private var font1:Class;

The embedAsCFF value is what will determine if the font is embedded as DefineFont3 (false) or DefineFont4 (true). As you may know, TLF components require DF4. This is valid for TrueType (.ttf) and OpenType (.otf) fonts alike, despite the 'CFF' letters in the keyword.

you're right but when you embed a font like that in flex, it convert the font in swf with flex-fontkit.jar, that create the cff table with java. I can't use this because i need to convert the font when the air application run and not when i create the air application. if you got an idea...

thanks

OK, I guess you're looking for a way to generate low-level font data in AS3. I can tell you that there's no native solution. You may be able to find a library somewhere that does it, but I don't know of any.

If you want to pursue the approach of running a font converter from the command line, I think you could try FontForge.

Good luck!
