在Silverlight中新增了对OpenType字体属性的支持，它主要通过Typography类的相关属性来控制。下面我们来看看它增加了哪些属性。
注意：必须使用系统的OpenType字体才行，所以FontFamily="Gabriola"。
一、连笔字
在"ft"之间相连起来，如下图绿色框内所示主要通过 Typography.StandardLigatures的True或者False来决定是否连笔：
然后我们看代码如下：
- <TextBlock FontFamily="Gabriola" FontSize="100" HorizontalAlignment="Center"
- Margin="33,304,142,114" Text="NewsftepSet-"
- Typography.StandardLigatures="False" Width="525" />
- <TextBlock FontFamily="Gabriola" FontSize="100" HorizontalAlignment="Center"
- Margin="33,406,142,12" Text="NewsftepSet-"
- Typography.StandardLigatures="True" Width="525" />
二、分数字
将1/5、4/13等分数按照数学上的分数字来显示，通过设置Typography.Fraction属性为Normal、Slashed、Stacked来控制。
其代码如下：
- <TextBlock Text="5/152 Normal" HorizontalAlignment="Center"
- FontFamily="Gabriola" FontSize="50" Height="100"
- Typography.Fraction="Normal" Margin="487,313,12,187" />
- <TextBlock Text="5/152 Slashed" HorizontalAlignment="Center"
- FontFamily="Gabriola" FontSize="50" Height="100"
- Typography.Fraction="Slashed" Margin="487,373,31,0" VerticalAlignment="Top" />
- <TextBlock Text="5/152 Stacked" HorizontalAlignment="Center"
- FontFamily="Gabriola" FontSize="50" Height="100"
- Typography.Fraction="Stacked" Margin="487,419,9,81" />
三、上下标字
比如化学里的三氧化二铁等，通过设置Typography.Variants属性为Subscript、Superscript来实现上下标。如下图：
其具体代码如下：
- <TextBlock FontFamily="Gabriola" FontSize="50" Height="100"
- HorizontalAlignment="Center" Margin="487,488,117,12" >
- <Run Text="Fe" Typography.Variants="Normal" />
- <Run Text="2" Typography.Variants="Subscript" />
- <Run Text="O" Typography.Variants="Normal" />
- <Run Text="3" Typography.Variants="Superscript" />
- </TextBlock>
四、手写字
在生活中我们需要一些比较漂亮的手写字，在Silverlight 5 RC版本中准备了7种样式的手写字，通过设置Typography.StylisticSet*的True、False来实现，其中*号是从1到7的整数 字来代替，8以上的数字设置是无效的。如下图：
其代码如下所示：
- <TextBlock Text="NewsftepSet-" HorizontalAlignment="Center" FontSize="50"
- Height="100" FontFamily="Gabriola" Margin="20,12,484,488" />
- <TextBlock Text="NewsftepSet1" HorizontalAlignment="Center" FontSize="50" FontFamily="Gabriola"
- Typography.StylisticSet1="True" Height="100" Margin="245,12,255,488" />
- <TextBlock FontFamily="Gabriola" FontSize="50" Height="100" HorizontalAlignment="Center"
- Margin="471,12,28,488" Text="NewsftepSet2" Typography.StylisticSet2="True" />
- <TextBlock FontFamily="Gabriola" FontSize="50" Height="100" HorizontalAlignment="Center"
- Margin="20,118,478,382" Text="NewsftepSet3" Typography.StylisticSet3="True" />
- <TextBlock FontFamily="Gabriola" FontSize="50" Height="100" HorizontalAlignment="Center"
- Margin="246,118,246,382" Text="NewsftepSet4" Typography.StylisticSet4="True" />
- <TextBlock FontFamily="Gabriola" FontSize="50" Height="100" HorizontalAlignment="Center"
- Margin="471,118,25,382" Text="NewsftepSet5" Typography.StylisticSet5="True" />
- <TextBlock FontFamily="Gabriola" FontSize="50" HorizontalAlignment="Center" Width="221"
- Margin="20,224,459,253" Text="NewsftepSet6" Typography.StylisticSet6="True" />
- <TextBlock FontFamily="Gabriola" FontSize="50" HorizontalAlignment="Center" Width="218"
- Margin="247,224,235,253" Text="NewsftepSet7" Typography.StylisticSet7="True" />
