libdcp/src/subtitle_asset.cc, branch v1.8.69

Add SubtitleAsset::ensure_font().

2023-05-11T23:35:26Z

Remove xmlns:xs namespace from subtitle XML (DoM #2498).

2023-04-19T10:59:37Z

Change how whitespace in subtitles is handled.

2023-02-16T20:56:22Z

Previously we would discard any whitespace subtitle content we found. This had the side-effect of making a verification test fail (checking that at least one subtitle is in each reel; blank subtitles are often used to avoid this warning). Here we take any subtitle content, whitespace or not, inside a or node which I think is a little more correct.

Add Z position to subtitles; existing tests pass.

Better subtitle comparisons in tests.

2022-09-26T17:44:32Z

Nearly pretty-print subtitle XML (though not in nodes).

2022-03-20T20:20:58Z

This is an attempt to fix DoM bug #2205.

Order subtitles in the XML according to their vertical position (DoM bug #2106).

2021-10-24T18:52:11Z

Basic implementation of tag in subtitles.

2021-10-13T20:18:59Z

Remove some unused using commands.

Improve handling of image subtitle IDs in XML (DoM bug #1965)

2021-04-14T14:20:53Z

When reading/writing the XML for image subtitles, we assumed that the content of the tag is just the ID of the PNG in the MXF, without any prefix. DoM bug #1965 mentions a DCP where this is not the case, and SMPTE 429-5-2009 has an example where there is urn:uuid: in the XML. This change makes DoM write this urn:uuid: prefix, and accept it if it's present (but not complain if it's not). If the urn:uuid: _is_ required in the field, it's a bit surprising that nobody has complained up to this point. Maybe nobody noticed, or nobody reported it.
