They can be specified in any order and are described below. Bar line padding One optional directive is padding. It can be used to force Mup to place extra white space to the left of the bar line. It is also possible to associate a location tag with a bar line. The y coordinate of a bar line is not very useful.
Special rules apply if a bar line happens to be placed at the end of a score.
Any locations taken relative to the bar that would be to the right of the bar are treated as if the bar line were at the beginning of the following score, just beyond the clef and time and key signatures, if any. Endings First and second endings, etc. If you change font or size or include special characters in the ending label, the output is not likely to be aligned properly. Endings cannot start at or cross over a restart bar. Rehearsal marks Rehearsal letters or numbers can be specified on any bar line.
