Specified by:

getType in class FontSourceBase

Returns:

The type of the font source. The returned value is one of FontSourceType constants.

getFontDataInternal

public java.lang.Iterable getFontDataInternal()

Overrides:

getFontDataInternal in class FontSourceBase

getSystemFontFolders

public static java.lang.String[] getSystemFontFolders()
                                               throws java.lang.Exception

Returns system font folders or empty array if folders are not accessible.

Remarks:

On some platforms Aspose.Words could search system fonts not only through folders but in other sources too. For example, on Windows platform Aspose.Words search fonts also in the registry.
