public class FontConfigSubstitutionRule : FontSubstitutionRule
Properties
Name | Description |
---|---|
override Enabled { set; } | Specifies whether the rule is enabled or not. |
Methods
Name | Description |
---|---|
IsFontConfigAvailable() | Check if fontconfig utility is available or not. |
ResetCache() | Resets the cache of fontconfig calling results. |
Remarks
This rule uses fontconfig utility on Linux (and other Unix-like) platforms to get the substitution if the original font is not available.
If fontconfig utility is not available then this rule will be ignored.
Examples
Shows operating system-dependent font config substitution.
FontSettings fontSettings = new FontSettings();
FontConfigSubstitutionRule fontConfigSubstitution =
fontSettings.SubstitutionSettings.FontConfigSubstitution;
bool isWindows = new[] {PlatformID.Win32NT, PlatformID.Win32S, PlatformID.Win32Windows, PlatformID.WinCE}
.Any(p => Environment.OSVersion.Platform == p);
// The FontConfigSubstitutionRule object works differently on Windows/non-Windows platforms.
// On Windows, it is unavailable.
if (isWindows)
{
Assert.False(fontConfigSubstitution.Enabled);
Assert.False(fontConfigSubstitution.IsFontConfigAvailable());
}
bool isLinuxOrMac =
new[] {PlatformID.Unix, PlatformID.MacOSX}.Any(p => Environment.OSVersion.Platform == p);
// On Linux/Mac, we will have access to it, and will be able to perform operations.
if (isLinuxOrMac)
{
Assert.True(fontConfigSubstitution.Enabled);
Assert.True(fontConfigSubstitution.IsFontConfigAvailable());
fontConfigSubstitution.ResetCache();
}
