The CairoHintMetrics class

INTRODUCTION

	Specifies  whether to hint font metrics; hinting font metrics means quantizing them so that they are integer values in device space. Doing
       this improves the consistency of letter and line spacing, however it also means that text will be laid out differently  at  different  zoom
       factors.

CLASS SYNOPSIS

PREDEFINED CONSTANTS

	      o CairoHintMetrics::METRICS_DEFAULT -Hint metrics in the default manner for the font backend and target device

NAME

       Graphics::Primitive::Font - Text styling

DESCRIPTION

       Graphics::Primitive::Font represents the various options that are available when rendering text.  The options here may or may not have an
       effect on your rendering.  They represent a cross-section of the features provided by various drivers.  Setting them should not break
       anything, but may not have an effect if the driver doesn't understand the option.

SYNOPSIS

	 use Graphics::Primitive::Font;

	 my $font = Graphics::Primitive::Font->new({
	   family => 'Arial',
	   size => 12,
	   slant => 'normal'
	 });

METHODS

   Constructor
Attributes
   antialias_modes
       Set the antialiasing mode for this font. Possible values are default, none, gray and subpixel.

   family
       Set this font's family.

   hint_metrics
       Controls whether to hint font metrics.  Hinting means quantizing them so that they are integer values in device space.  This improves the
       consistency of letter and line spacing, however it also means that text will be laid out differently at different zoom factors.	May not be
       supported by all drivers.

   hint_style
       Set the the type of hinting to do on font outlines.  Hinting is the process of fitting outlines to the pixel grid in order to improve the
       appearance of the result. Since hinting outlines involves distorting them, it also reduces the faithfulness to the original outline shapes.
       Not all of the outline hinting styles are supported by all drivers.  Options are default, none, slight, medium and full.

   size
       Set/Get the size of this font.

   slant
       Set/Get the slant of this font.	Valid values are normal, italic and oblique.

   subpixel_order
       Set the order of color elements within each pixel on the display device when rendering with subpixel antialiasing.  Value values are
       default, rgb, bgr, vrgb and vbgr.

   variant
       Set/Get the variant of this font.  Valid values are normal or small-caps.

   weight
       Set/Get the weight of this font.  Value valies are normal and bold.

METHODS

   new
       Creates a new Graphics::Primitive::Font.

   derive
       Clone this font but change one or more of it's attributes by passing in a hashref of options:

	 my $new = $font->derive({ attr => $newvalue });

       The returned font will be identical to the cloned one, save the attributes specified.
