NAME

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

SYNOPSIS

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

DESCRIPTION

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

OPTIONS

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.

BUGS

Please report them.
