Ace::Graphics::Glyph::anchored_arrow - The "anchored_arrow" glyph


  See L<Ace::Graphics::Panel> and L<Ace::Graphics::Glyph>.


This glyph draws an arrowhead which is anchored at one or both ends (has a vertical base) or has one or more arrowheads. The arrowheads indicate that the feature does not end at the edge of the picture, but continues. For example:

    |-----------------------------|          both ends in picture
 <----------------------|                    left end off picture
         |---------------------------->      right end off picture
 <------------------------------------>      both ends off picture


In addition to the standard options, this glyph recognizes the following:

  Option         Description                Default
  -tick          draw a scale               0
  -rel_coords    use relative coordinates   false
                 for scale

The argument for b<-tick> is an integer between 0 and 2 and has the same interpretation as the b<-tick> option in Ace::Graphics::Glyph::arrow.

If b<-rel_coords> is set to a true value, then the scale drawn on the glyph will be in relative (1-based) coordinates relative to the beginning of the glyph.


Please report them.
