ISSUE-24: subscript and superscript support
script
subscript and superscript support
- State:
- CLOSED
- Product:
- TTML2
- Raised by:
- Pierre-Anthony Lemieux
- Opened on:
- 2008-12-05
- Description:
- Interoperability with current practice in US captioning has been expressed as a desirable goal, however CEA 708 offers text subscript/ out - no equivalent mechanism exists in DFXP for intermediate animation. Could set font height in a span, but no way to accurately move baseline of character.
Should subscript and superscript be added to DFXP (possibly by a baseline attribute on span)?
