\draw-hline

Draws a line across a page, where the property span-factor controls what fraction of the page is taken up.

  \column {
    \draw-hline
    \override #'(span-factor . 1/3)
    \draw-hline
  }

\filled-box xext (pair of numbers) yext (pair of numbers) blot (number)

Draw a box with rounded corners of dimensions xext and yext. For example,

\filled-box #'(-.3 . 1.8) #'(-.3 . 1.8) #0

creates a box extending horizontally from -0.3 to 1.8 and vertically from -0.3 up to 1.8, with corners formed from a circle of diameter 0 (i.e., sharp corners).

\markup {
  \filled-box #'(0 . 4) #'(0 . 4) #0
  \filled-box #'(0 . 2) #'(-4 . 2) #0.4
  \filled-box #'(1 . 8) #'(0 . 7) #0.2
  \with-color #white
  \filled-box #'(-4.5 . -2.5) #'(3.5 . 5.5) #0.7
}

\hbracket arg (markup)

Draw horizontal brackets around arg.

\markup {
  \hbracket {
    \line {
      one two three
    }
  }
}

\parenthesize arg (markup)

Draw parentheses around arg. This is useful for parenthesizing a column containing several lines of text.

\markup {
  \line {
    \parenthesize {
      \column {
        foo
        bar
      }
    }
    \override #'(angularity . 2) {
      \parenthesize {
        \column {
          bah
          baz
        }
      }
    }
  }
}

Used properties:

  • width (0.25)
  • thickness (1)
  • size (1)
  • padding
  • angularity (0)
\path thickness (number) commands (list)

Draws a path with line thickness thickness according to the directions given in commands. commands is a list of lists where the car of each sublist is a drawing command and the cdr comprises the associated arguments for each command.

Line-cap styles and line-join styles may be customized by overriding the line-cap-style and line-join-style properties, respectively. Available line-cap styles are 'butt, 'round, and 'square. Available line-join styles are 'miter, 'round, and 'bevel.

The property filled specifies whether or not the path is filled with color.

There are seven commands available to use in the list commands: moveto, rmoveto, lineto, rlineto, curveto, rcurveto, and closepath. Note that the commands that begin with r are the relative variants of the other three commands.

The commands moveto, rmoveto, lineto, and rlineto take 2 arguments; they are the X and Y coordinates for the destination point.

The commands curveto and rcurveto create cubic Bézier curves, and take 6 arguments; the first two are the X and Y coordinates for the first control point, the second two are the X and Y coordinates for the second control point, and the last two are the X and Y coordinates for the destination point.

The closepath command takes zero arguments and closes the current subpath in the active path.

Note that a sequence of commands must begin with a moveto or rmoveto to work with the SVG output.

samplePath =
  #'((moveto 0 0)
     (lineto -1 1)
     (lineto 1 1)
     (lineto 1 -1)
     (curveto -5 -5 -5 5 -1 0)
     (closepath))

\markup {
  \path #0.25 #samplePath
}

Used properties:

  • filled (#f)
  • line-join-style (round)
  • line-cap-style (round)
\postscript str (string)

This inserts str directly into the output as a PostScript command string.

ringsps = #"
  0.15 setlinewidth
  0.9 0.6 moveto
  0.4 0.6 0.5 0 361 arc

rings = \markup {
  \with-dimensions #'(-0.2 . 1.6) #'(0 . 1.2)
  \postscript #ringsps
}

\relative c'' {
  c2^\rings
  a2_\rings

\rounded-box arg (markup)

Draw a box with rounded corners around arg. Looks at thickness, box-padding and font-size properties to determine line thickness and padding around the markup; the corner-radius property makes it possible to define another shape for the corners (default is 1).

c4^\markup {
  \rounded-box {
    Overtura
  }
}
c,8. c16 c4 r

Used properties:

  • box-padding (0.5)
  • font-size (0)
  • corner-radius (1)
  • thickness (1)
\scale factor-pair (pair of numbers) arg (markup)

Scale arg. factor-pair is a pair of numbers representing the scaling-factor in the X and Y axes. Negative values may be used to produce mirror images.

\markup {
  \line {
    \scale #'(2 . 1)
    stretched
    \scale #'(1 . -1)
    mirrored
  }
}

  \hspace #2
  \triangle ##f
}

Used properties:

  • baseline-skip (2)
  • font-size (0)
  • thickness (0.1)
\with-url url (string) arg (markup)

Add a link to URL url around arg. This only works in the PDF backend.

\markup {
  \with-url #"http://lilypond.org/" {
    LilyPond ... \italic {
      music notation for everyone
    }
  }
}
