notes with colored="true" and dur="2" get rendered in without the note head color inversion (CMN) #3605

Open fernandoherreradelasheras opened 9 months ago

in CMN colored="true" is reflected by inverting the note head fill / void. This works fine for all note durations but for dur="2" that remains as a normal half note (and it should look like a quarter note).

currently renders to:

and it should be:

note-012

note@colored is intended for mensural music, is that related to why you are using it in CMN?

In white mensural notation, the minim is being colored properly:

By coloring a semibreve that should be perfect (according to some rules) it is forced to be imperfect and last 2 minimas instead of 3.</p> <p><img src="https://github.com/rism-digital/verovio/assets/20201639/8e8f0f16-5549-4056-8dbf-ed4013acfd6c" alt="Screenshot from 2024-02-24 17-12-58" /></p> <p>Notice in the example above that when forcing a semibreve to be imperfect you not only color the semibreve itself but also the surrounding notes. On those, the coloring has no effect at all in terms of duration changes and was intended only as a visual clue for performers about the rythm "alteration"</p> </div> </div> <div class="comment"> <div class="user"> <a rel="noreferrer nofollow" target="_blank" href="https://github.com/craigsapp"><img src="https://avatars.githubusercontent.com/u/3487289?v=4" />craigsapp</a> commented <strong> 9 months ago</strong> </div> <div class="markdown-body"> <p>Thanks, so you are encoding in an intermediate format with performance durations interpreted later, and you use <code>note@colored</code> for analytic information are part of this process.

Usually this diplomatic transcription has no real interest for anyone other than the 3 or 4 musicologists working around that music. </p> <p>However on a couple of projects I am working on some parts of the manuscripts are in bad conditions with ink bleed-through, corroded paper and all the usual suspects. So every time I have to go back to the original implies a lot of time spent "deciphering" again the obscure parts.
