Objects belonging outside the staff include things such as rehearsal marks, text and dynamic markings (from now on, these will be called outside-staff objects). LilyPond's rule for the vertical placement of outside-staff objects is to place them as close to the staff as possible but not so close that they collide with another object. <p>LilyPond uses the <code>outside-staff-priority</code> property to determine whether a grob is an outside-staff object: if <code>outside-staff-priority</code> is a number, the grob is an outside-staff object. In addition, <code>outside-staff-priority</code> tells LilyPond in which order the objects should be placed. <p>First, LilyPond places all the objects that do not belong outside the staff. Then it sorts the outside-staff objects according to their <code>outside-staff-priority</code> (in increasing order). One by one, LilyPond takes the outside-staff objects and places them so that they do not collide with any objects that have already been placed. That is, if two outside-staff grobs are competing for the same space, the one with the lower <code>outside-staff-priority</code> will be placed closer to the staff. <blockquote> <pre class="verbatim"> c4_"Text"\pp r2. \once \override TextScript #'outside-staff-priority = #1 c4_"Text"\pp % this time the text will be closer to the staff r2. % by setting outside-staff-priority to a non-number, % we disable the automatic collision avoidance \once \override TextScript #'outside-staff-priority = ##f \once \override DynamicLineSpanner #'outside-staff-priority = ##f c4_"Text"\pp % now they will collide </pre> <p> <a href="../0b/lily-bfb92213.ly"> <img align="middle" border="0" src="../0b/lily-bfb92213.png" alt="[image of music]"> </a> </p> </blockquote> <p>The vertical padding between an outside-staff object and the previously-positioned grobs can be controlled with <code>outside-staff-padding</code>. <blockquote> <pre class="verbatim"> \once \override TextScript #'outside-staff-padding = #0 a'^"This text is placed very close to the note" \once \override TextScript #'outside-staff-padding = #3 c^"This text is padded away from the previous text" c^"This text is placed close to the previous text" </pre> <p> <a href="../3c/lily-7a69aac1.ly"> <img align="middle" border="0" src="../3c/lily-7a69aac1.png" alt="[image of music]"> </a> </p> </blockquote> <p>TODO: this example doesn't work any more ? <p>By default, outside-staff objects are placed without regard to their horizontal distance from the previously-positioned grobs. This can lead to situations in which objects are placed very close to each other horizontally. Setting <code>outside-staff-horizontal-padding</code> causes an object to be offset vertically so that such a situation doesn't occur. <blockquote> <pre class="verbatim"> % the markup is too close to the following note c2^"Text" c''2 % setting outside-staff-horizontal-padding fixes this R1 \once \override TextScript #'outside-staff-horizontal-padding = #1 c,,2^"Text" c''2 </pre> <p> <a href="../bf/lily-d122a587.ly"> <img align="middle" border="0" src="../bf/lily-d122a587.png" alt="[image of music]"> </a> </p> </blockquote> <!-- footer_tag --><br><hr> <div class="node"> <p> Previous: <a rel="previous" accesskey="p" href="Two_002dpass-vertical-spacing.es.html#Two_002dpass-vertical-spacing">Two-pass vertical spacing</a>, Up: <a rel="up" accesskey="u" href="Vertical-spacing.es.html#Vertical-spacing">Vertical spacing</a> </div> <div style="background-color: #e8ffe8; padding: 2; border: #c0ffc0 1px solid;"> <p> <font size="-1"> Esta página corresponde a LilyPond-2.11.57 (rama de desarrollo). <br> <address> Informe de los fallos a través de la lista en español <a href="http://es.groups.yahoo.com/group/lilypond-es/">lilypond-es</a>, o en inglés a través de <a href="http://post.gmane.org/post.php?group=gmane.comp.gnu.lilypond.bugs">http://post.gmane.org/post.php?group=gmane.comp.gnu.lilypond.bugs</a>. </address> <br> Se agradecen las <a href="http://lilypond.org/web/devel/participating/documentation-adding">sugerencias para la documentación</a>. </font> </p> </div> </BODY></html>
