Re: Background Colour

[darkijah]

Found the snippet and changed the colors so better to point it out - 
yet... that is as far as I can help.

\paper {
  indent = 0\mm
  line-width = 160\mm
  % offset the left padding, also add 1mm as lilypond creates cropped
  % images with a little space on the right
  line-width = #(- line-width (* mm  3.000000) (* mm 1))
}

\layout {

}

制限: PDF でのみ動作します。

リンクされたオブジェクトに色が付いているのは、別のコマンドによるものです。

La fonction @code{add-link}, telle que définie ci-dessous, permet
d'ajouter un lien au stencil d'un objet graphique.  Elle s'emploie
au sein d'un @code{\\override} ou d'un @code{\\tweak}.

À noter que le fonctionnemment du @code{point-and-click} est perturbé
sur les objets ainsi liés.

Cette fonction n'est opérationnelle que pour une sortie PDF.

La coloration des objets liés s'obtient par une commande séparée.

To add a link to a grob-stencil you could use @code{add-link} as
defined here. Works with @code{\\override} and @code{\\tweak}.

Drawback: @code{point-and-click} will be disturbed for the linked
grobs.

Limitation: Works for PDF only.
