Thanks for the rapid response. I am working on a new version of my old
spatium issues - I worked with you on those two years ago. I'll be
asking you soon about how you feel about changing the units for these
page sizes and margins from inches to points, as in PostScript points
@72dpi and QPageSize::Point. I'm using QPageLayout, QPageSize, and
QMarginsF, and they handle all the unit conversions. I can provide you
with solid rationale for using points, but it's also not a big deal to
continue storing these settings in inches, especially with these Qt
classes to handle all the conversions. The one that must change is the
spatium. It really must change to be stored in points so that the
default can be stored as a whole number 5, and there are no more
floating point issues and excess scaling operations.
I don't necessarily want to have that discussion on the mailing list,
but I want to keep raising this spatium issue, as I've gotten very
little feedback on it. I know that everyone is busy with the beta, so I
understand. This issue impacts my development in a serious enough way
that I'm sticking with it.
Thanks!

Hi,
Sure. As you guessed, the JSON functions are only for a separate
storage mechanism. They are mainly used by the MuseScore.com backend
in order to extract information about the score and display them to
the user.

I just encountered the JSON storage implementation for page settings:
QJsonObject jsonPageformat;
It's part of 3 new functions at the bottom of mscore/file.spp -
saveMetadataJSON() (plus an overloaded version) and
exportAllMediaFiles().
Is there a plan to move page settings out of XML and into JSON? Or is
this simply a separate storage mechanism for page settings and a few
select styles?
I hate to name names, but I think I've seen @lasconic as being the
author of these function - are you available to comment, sir?
Can you explain the context and purpose of these JSON settings? I
see
no mention of JSON in the forum post/discussion about the 3.0 beta
release.
Thanks!
