Fields| Name | Description | |
|---|---|---|
 | _dictDescriptionStringToGdiFont | Corresponds the font's invariant description string with the Gdi+ font instance. Key is the invariant description string, value is the Gdi font instance with the specific style and size. |
| _dictWin32FamilyNameToGdiFontFamilyAndPresence | Dictionary of the Gdi font families. Key is the Win32FamilyName, value is an array[4] of FontFamily with represent the styles regular, bold, italic, and bold-Italic. For system fonts, the 4 font family instances will be identical, but due to a bug in Windows 10, to create a private font family we need to load each font file in a separate PrivateFontCollection, thus creating a separate FontFamily for each style. |
| _gdiFontReferenceCounter | Corresponds the font's invariant description string with a reference counter. It counts the number of FontX instances with this description string. When the reference counter falls down to zero, the Gdi+ font instance can be released. |
| _instanceCached | The instance used by the static methods of this class. Is not neccessarily of type GdiFontManager, but could also be a derived type. |
