Saucy
=====

Dynamic Text Rendering Plugin for Rails. Like sIFR but without the hassle/flash/javascript.

* Automatic caching
* SEO friendly
* render any TTF font

Examples
--------

  <%= saucy_tag("Hi there") %>
  <%= saucy_tag("I am red", :style => {:font => {:color => 'red' }}) %>
  <%= saucy_tag("I am a red/blue sprite", 
                  :style => {:font => {:color => 'red'}}, 
                  :highlight => {:font => {:color => 'blue'}}
                ) %>
  
Use
---

In a view:

  <%= saucy_tag(text, options) %>

* text: your own text. Note it can contain newlines which will be interpreted as multiline text.
* options: html attributes to be inserted


Available options
-----------------

# Style needs to be a hash - see the 'Styles' heading below
{:style => {}}

# Highlight option is for sprites, the styles passed in override
# the styles that were passed in for :style. This can be used for hover or focus effects
{:highlight => {}}

# The html style needs to be a hash
# The html class needs to be a array of classNames
{:html => {:style => {}, :class => []}}

# Tag needs to be symbol (default is :a)
{:tag => :p}

# Transparent needs to be a boolean - 
# this defaults to true 
{:transparent => false}

Styles
------

The style has has several options and the default style is: 

  { 
    :background => "transparent",
    :font       => {
      :size     => 18, 
      :color    => "#000", 
      :font     => "arial", 
      :stretch  => "normal"
    },
    :stroke => {
      :width    => 0, 
      :color    => "#000", 
      :inner    => true 
    },
    :spacing    => {
      :letter   => 0, 
      :word     => 0
    },
    :rotate => 0,
    :shadow => {
      :color => "#000", 
      :opacity => 0.6, 
      :top => 2, 
      :left => 2, 
      :blur => 5.0, 
      :render => false 
    }
  }

The style that's passed in will be merged over the top of this. 

Internet Explorer
-----

Saucy will apply an AlphaFilter if you the background color is "transparent" (or absent since this is the default)

Fonts
-----

Fonts are loaded from the /plugins/saucy/fonts directory.

Sprites
-------

If you set an highlight style Saucy will render a sprite consisting of 2 images, the normal and the highlight.
To set a sprite to be at the highlight style, simply set the top margin to 0. E.g. the following is for a hover effect:

  <style type="text/css" media="screen">
    .saucySprite:hover {
      margin-top: 0 !important;
    }
  </style>

You need to pass in a :highlight option which is in the same format as the :style option.
The :highlight option overrides the :style option (you don't need to pass in all the styles again).
