https://www.w3.org/Bugs/Public/show_bug.cgi?id=23404 Bug ID: 23404 Summary: Redesign line position settings Product: TextTracks CG Version: unspecified Hardware: PC OS: All Status: NEW Severity: normal Priority: P2 Component: WebVTT Assignee: silviapfeiffer1@gmail.com Reporter: silviapfeiffer1@gmail.com QA Contact: dave.null@w3.org CC: mike@w3.org, public-texttracks@w3.org In bug 20037 we've redesigned text position settings. This bug is about the "line" cue setting. "line" settings position lines of text off the top of the video. With snap-to-lines set (i.e. non-percentage values) the video viewport is divided into lines and the positioning is by line number. With percentage, users expect 0% to refer to the top of the cue box, 50% refer to the center of the cue box, and 100% refer to the bottom of the cue box. Right now the rendering algorithm does so by positioning the x% point of the cue box at x% of the video viewport's height (for horizontal cues; width for vertical cues). However, this leads to hard to authoring content, e.g. to position the top of a cue box exactly 20% down the video viewport, an author needs to make complicated calculations to determine the "line" value that position equates to. -- You are receiving this mail because: You are on the CC list for the bug.
