(I edited my first posting in order to be more precise)
In “Engraving Options/Staves” one can set the Staff line thickness.
It is possible to choose between some values expressed in division, for example 1/8 or 1/4.
It is also possible to write your own values like 1/10 (for 0.1) or 3/20 (for 0.15)
It is also possible to directly write 0.1 and Dorico converts it to 1/10.
At first sight it seems also that Dorico converts 0.125 correctly to 1/8.
But hovering with the mouse on the arrow Dorico shows the decimal value 0.13 for 1/8
It seems as if Dorico can only use only two decimal after the comma.
-
Why does Dorico shows divisions if they cannot be calculted exactly?
-
It is possible to set the value 0.
The score changes then and the staff lines are quite thin, but what is the spaces value when 0 is choosed?
Hovering with the mouse over the arrows shows nothing. -
It is possible to set negative values.
-1/8 changes the thickness to something like + 9/50
-1/4 seems to be similar to -1/8
From -3/8 each new negative value shortens the bar line!
Is it the way it is supposed to be?
All these questions are essentially out of curiosity, I can live with what Dorico offers in this field, I am just trying to understand what the program does.
