Ace::Graphics::Glyph::toomany - The "too many to show" glyph

SYNOPSIS

Top

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

DESCRIPTION

Top

This glyph is intended for features that are too dense to show properly. Mostly a placeholder, it currently shows a filled oval. If you choose a bump of 0, the ovals will overlap, to give a cloud effect.

OPTIONS

There are no glyph-specific options.

BUGS

Top

Please report them.
