deco name type func h wl wr [str]

Define a decoration.

This command assumes a good knowledge of the txtmus/abc2svg/abcm2ps internals.

The arguments are:

• name: name of the decoration.
  If it is the name of an existing decoration, this one is redefined.
  When this name begins with 'head-', the note head is not drawn.
• type: type of the decoration.
  The possible types are:
  • 0, 1, 2: the decoration goes near the note, possibly inside the staff.
    • 0: 'dot', 'tenuto'...
    • 1: 'slide' or decoration on a note stem (not abcm2ps)
    • 2: 'arpeggio'
  • 3, 4: the decoration goes near the note but outside the staff. It is usually printed above the staff.
    • 3: general
    • 4: below the staff
  • 5, 6, 7: the decoration is tied to the staff. It is generally printed below the staff.
    • 5: above the staff (not abcm2ps)
    • 6: dynamic marks
    • 7: below the staff (not abcm2ps)
  • 8: glissendo
  • 9: alternate head
  • 10: color of the note head (not abcm2ps). The color is the name of the decoration and func is ignored
• func: with abcm2ps, postscript definition, with txtmus and abc2svg, glyph name, javascript function or SVG <defs>.
• h: decoration height.
  It is the minimum height for !arpeggio!.
  With txtmus and abc2svg, h may contain two values separated by a comma. The first value is the ascent, the second value is the descent.
• wl and wr: left and right widths.
• str: text to display (for some functions - see code).
  The text may begin with '@' (at sign) followed by x and y coordinates as in annotations.
  With abcm2ps, func is not used. The default font is the annotationfont.

  With txtmus and abc2svg, func is mandatory. Some function are already internally defined. These are crdc (italic 14px - default definition) and dacs (bold 15 px). @ as the class is accepted for compatibility and replaced by at.
