joeyparrish has just created a new issue for https://github.com/w3c/ttml-webvtt-mapping: == tts:origin to VTTCue position/line looks backwards == This text in the mapping spec looks backward to me: > To convert tts:origin to WebVTT cue settings: > ... > - If the block progression direction is top to bottom: > - The value of the "line" cue setting is the percentage value for the second coordinate of the origin attribute. > - The value of the "position" cue setting is the percentage value for the first coordinate of the origin attribute. > - If the block progression direction is left to right: > - The value of the "line" cue setting is the percentage value for the first coordinate of the origin attribute. > - The value of the "position" cue setting is the percentage value for the second coordinate of the origin attribute. The VTT spec says: > The position defines the indent of the cue box in the direction defined by the writing direction. For horizontal text (left to right), the x coordinate (first coordinate) should be used to indent the text horizontally. Therefore the first coordinate should set position, not line. Is this a mistake, or do I misunderstand the specs? Please view or discuss this issue at https://github.com/w3c/ttml-webvtt-mapping/issues/25 using your GitHub account
