The help line has offset problems in some cases

[zhwei8090]

These are the two scores I tested. I tried to find the problem, but I haven't broken through.. test.zip

The guido library is adapted according to which notation software, because I found that the effects presented by different software are a little different

[arshiacont]

@zhwei8090 Guido Library is dependent by itself and is a renderer of the Guido Language. If you are talking about LibMusicXML, then the answer is Finale XML Export.

I believe in your case, it is best to submit the GUIDO score for debugging. If you believe the problem is on LibMusicXML then create a ticket on the corresponding GitHub.

I just looked at test1 and it looks like a rendering issue (rendered on GuidoEditor online):

@arshiacont Yes, I think there is a problem with the offset calculated in the OnDraw method of GRSingleNote, but I still don’t know how to change it.

@dfober thank you very much
