GuidoGetMap returns rects for many elements.

It would be nice if:

• Key placement was returned
• Dynamics placement was returned
• Text placement was returned
• Lyrics placement was returned
• Articulation placement was returned

Best.

I'm afraid I won't have time to extend the mapping for a while.
If you'd like to try your hand at it, I can show you how. It's not necessarily difficult, but it does take a bit of time.
The mapping is based on the elements bounding boxes and one of the problems that can occur is that the bounding boxes are not exact (when the elements are adjusted manually e.g. dx, dy, size...). That's what can take time.

Yes, tell me how.
Happy new Year also.

Happy new year too !

Here are some indications:
all graphic objects (GR) have a mMapping field, computed from the bounding box (mBoundingBox) that stores mapping information (which may be slightly different from the bounding box)
see GObject.h

to extend the mapping:

• extend GuidoElementSelector and GuidoElementType with you target types (GuidoScoreMap.h)
• make sure that the mMapping field is set by the target object type
  mMapping is computed by GR objects, generally by the updateBoundingBox method, but for a set of objects it is set by the setHPosition method (objects that don't implement updateBoundingBox)
• the target object must override the GetMap method (defined in GObject)

That's basically the way the extend the mapping (not sure that I didn't forget a point)
Keep me informed and I'll be happy with a PR at the end.
