deco name type func h wl wr [str]

Define a decoration.

This command assumes a good knowledge of the abcm2ps/abc2svg 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'
    • 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 (abc2svg only). The color is the name of the decoration and func is ignored
• func: with abcm2ps, postscript definition with abc2svg, glyph name or javascript function.
• h: decoration height.
  It is the minimum height for !arpeggio!.
  With abc2svg, h may contain two values separated by a comma. The first value is the ascent, the second one is the descent.
• wl and wr: left and right widths. These values are actually used for general dynamic marks only.
• 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 abc2svg, func is mandatory. It may not be a function in which case it is seen as a class name that defines the font. Some classes 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.
