为什么精简字体在FireMonkey中无法正确显示？

Question

（我该怎么办？）

如果我在VCL中创建两个标签并设置一个使用Arial和另一个Arial Narrow，我会看到预期的结果。

如果我在Firemonkey中执行相同操作，则第二个标签不会显示在Arial Narrow中。它甚至没有在Arial中显示（我的圆点是圆的，'s'的形状都是错的等等。）

有人知道为什么FM（我用Delphi XE4进行测试）没有正确显示字体吗？我有什么可以做的吗？

Answer 1

这似乎只会影响系列中的字体 - 如果字体文件夹中的字体不存在于其自己的系列名称下。例如，Arial Narrow是“Arial”字体文件中的一种字体（它存在于一个家庭中，本身并不是一个家族）。

通常，字体系列仅包含四种样式

Arial （天真地包含）

• Arial Regular
• Arial Bold
• Arial Italic
• Arial Bold Italic

然而，“Arial Narrow”存在于“Arial”系列中，与标准风格一致 - 即：

Arial （实际上包含）

• Arial Regular
• Arial Bold
• Arial Italic
• Arial Bold Italic
• Arial Narrow
• Arial Narrow Bold
• Arial Narrow Italic
• Arial Narrow Bold Italic
• Arial Black

似乎FMX只在任何给定的字体系列中看起来只有一个级别，并且没有查看任何偏离严格的GDI +样式定义的样式变体（Regular，Bold，Italic，Bold Italic）。

通过检查，这也会影响Arial Black - 通过运行fonts文件夹很容易找到其他示例。 Franklin Gothic Demi，Gill Sans Ultra Bold等......任何遵循上述模式的东西。遇到这些字体时，字体似乎会在默认的Segoe UI中呈现。

权宜之计解决方案是使用Arial并将Scale属性设置为X=0.82 - 它并不完美，但它与Arial Narrow非常接近。

这可能是一个错误，应该是QC'd。
