我有一个 VB.NET Windows 窗体项目,它在运行时将文本直接绘制到窗体上。不过,在我用字体绘画之前,我想确保字体和字体大小存在于用户的机器上。如果他们不这样做,我会尝试其他一些类似的字体,最终默认使用 Arial 或其他字体。
在用户计算机上测试和验证字体的最佳方法是什么?
从题为“如何:枚举已安装字体”的 MSDN 文章中,我找到了以下代码:
InstalledFontCollection installedFontCollection = new InstalledFontCollection();
// Get the array of FontFamily objects.
FontFamily[] fontFamilies = installedFontCollection.Families;
这是一个解决方案,在 c# 中:
public partial class Form1 : Form
{
public Form1()
{
SetFontFinal();
InitializeComponent();
}
/// <summary>
/// This method attempts to set the font in the form to Cambria, which
/// will only work in some scenarios. If Cambria is not available, it will
/// fall back to Times New Roman, so the font is good on almost all systems.
/// </summary>
private void SetFontFinal()
{
string fontName = "Cambria";
Font testFont = new Font(fontName, 16.0f, FontStyle.Regular,
GraphicsUnit.Pixel);
if (testFont.Name == fontName)
{
// The font exists, so use it.
this.Font = testFont;
}
else
{
// The font we tested doesn't exist, so fallback to Times.
this.Font = new Font("Times New Roman", 16.0f,
FontStyle.Regular, GraphicsUnit.Pixel);
}
}
}
这是VB中的一种方法:
Public Function FontExists(FontName As String) As Boolean
Dim oFont As New StdFont
Dim bAns As Boolean
oFont.Name = FontName
bAns = StrComp(FontName, oFont.Name, vbTextCompare) = 0
FontExists = bAns
End Function
另请参阅导致此代码的相同问题:
private bool IsFontInstalled(string fontName) {
using (var testFont = new Font(fontName, 8)) {
return 0 == string.Compare(
fontName,
testFont.Name,
StringComparison.InvariantCultureIgnoreCase);
}
}
Arial Bold Italic 不太可能是一种字体。它是 Arial 家族的一个子类。
尽量保持简单并测试“Arial”。
