Meziantou.FrameworkFontResourceLimits Class
The limits that bound the work of the font code on untrusted input: the bytes read and kept, the work of decoding a glyph and the glyphs of a shaped text. Exceeding a limit throws a FontResourceLimitException.

Properties
| Name | Description |
|---|---|
| Default | Gets the default limits. |
| MaxCollectionFaces | Gets the maximum number of faces of a font collection. Each face is read when the collection is loaded. |
| MaxEncodedBytes | Gets the maximum number of bytes read from a font file. |
| MaxFontBytes | Gets the maximum number of bytes a font keeps in memory, after a compressed container is expanded. |
| MaxGlyphComplexity | Gets the maximum number of elementary operations (outline points, components, operators) to produce one glyph. |
