NAME

Bio::Graphics::Glyph::Factory - Factory for Bio::Graphics::Glyph objects

SYNOPSIS

See Bio::Graphics::Panel.

DESCRIPTION

This class is used internally by Bio::Graphics to generate new Glyph objects by combining a list of features with the user's desired configuration. It is intended to be used internally by Bio::Graphics.

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with an "_" (underscore).

new

  Title   : new
  Usage   : $f = Bio::Graphics::Glyph::Factory->new(
                     -stylesheet => $stylesheet,
		     -glyph_map  => $glyph_map,
		     -options    => $options);
  Function : create a new Bio::Graphics::Glyph::Factory object
  Returns  : the new object
  Args     : $stylesheet is a Bio::Das::Stylesheet object that can
                 convert Bio::Das feature objects into glyph names and
                 associated options.
             $glyph_map is a hash that maps primary tags to glyph names.
             $options is a hash that maps option names to their values.
  Status   : Internal to Bio::Graphics

clone

Title    : clone
Usage    : $f2 = $f->clone
Function : Deep copy of a factory object
Returns  : a deep copy of the factory object
Args     : None
Status   : Internal to Bio::Graphics

stylesheet

Title    : stylesheet
Usage    : $stylesheet = $f->stylesheet
Function : accessor for stylesheet
Returns  : a Bio::Das::Stylesheet object
Args     : None
Status   : Internal to Bio::Graphics

glyph_map

Title    : glyph_map
Usage    : $map = $f->glyph_map
Function : accessor for the glyph map
Returns  : a hash mapping primary tags to glyphs
Args     : None
Status   : Internal to Bio::Graphics

option_map

Title    : option_map
Usage    : $map = $f->option_map
Function : accessor for the option map
Returns  : a hash mapping option names to values
Args     : None
Status   : Internal to Bio::Graphics

global_opts

Title    : global_opts
Usage    : $map = $f->global_opts
Function : accessor for global options
Returns  : a hash mapping option names to values
Args     : None
Status   : Internal to Bio::Graphics

This returns a set of defaults for option values.

panel

Title    : panel
Usage    : $panel = $f->panel
Function : accessor for Bio::Graphics::Panel
Returns  : a Bio::Graphics::Panel
Args     : None
Status   : Internal to Bio::Graphics

This returns the panel with which the factory is associated.

scale

Title    : scale
Usage    : $scale = $f->scale
Function : accessor for the scale
Returns  : a floating point number
Args     : None
Status   : Internal to Bio::Graphics

This returns the scale, in pixels/bp for glyphs constructed by this factory.

font

Title    : font
Usage    : $font = $f->font
Function : accessor for the font
Returns  : a font name
Args     : None
Status   : Internal to Bio::Graphics

This returns a GD font name.

map_pt

Title    : map_pt
Usage    : @pixel_positions = $f->map_pt(@bp_positions)
Function : map bp positions to pixel positions
Returns  : a list of pixel positions
Args     : a list of bp positions
Status   : Internal to Bio::Graphics

The real work is done by the panel, but factory subclasses can override if desired.

map_no_trunc

Title    : map_no_trunc
Usage    : @pixel_positions = $f->map_no_trunc(@bp_positions)
Function : map bp positions to pixel positions
Returns  : a list of pixel positions
Args     : a list of bp positions
Status   : Internal to Bio::Graphics

Same as map_pt(), but it will NOT clip pixel positions to be within the drawing frame.

translate_color

Title    : translate_color
Usage    : $index = $f->translate_color($color_name)
Function : translate symbolic color names into GD indexes
Returns  : an integer
Args     : a color name in format "green" or "#00FF00"
Status   : Internal to Bio::Graphics

The real work is done by the panel, but factory subclasses can override if desired.

glyph

Title    : glyph
Usage    : @glyphs = $f->glyph($level,$feature1,$feature2...)
Function : transform features into glyphs.
Returns  : a list of Bio::Graphics::Glyph objects
Args     : a feature "level", followed by a list of FeatureI objects.
Status   : Internal to Bio::Graphics

The level is used to track the level of nesting of features that have subfeatures.

feature_to_glyph

Title    : feature_to_glyph
Usage    : $glyph_name = $f->feature_to_glyph($feature)
Function : choose the glyph name given a feature
Returns  : a glyph name
Args     : a Bio::Seq::FeatureI object
Status   : Internal to Bio::Graphics

set_option

Title    : set_option
Usage    : $f->set_option($option_name=>$option_value)
Function : set or change an option
Returns  : nothing
Args     : a name/value pair
Status   : Internal to Bio::Graphics

options

Title    : options
Usage    : @option_names = $f->options
Function : return all configured option names
Returns  : a list of option names
Args     : none
Status   : Internal to Bio::Graphics
