ISSUE-357: Add support for horizontal in vertical (tate-chu-yoko).

horizontal in vertical

Add support for horizontal in vertical (tate-chu-yoko).

State:

CLOSED

Product:

TTML2

Raised by:

Glenn Adams

Opened on:

2014-11-18

Description:

In order to support Japanese subtitle and caption requirements, it is necessary to support horizontal in vertical layout 縦中横 'tate-chu-yoko'. The previously added tts:textOrientation is not sufficient to handle all use cases involving mixtures of horizontal and vertical text.

One solution is to define a textCombine style property based the text-combine-upright property defined by CSS Writing Modes Level 3 [1].
