| float FTSize::Height | ( | ) | const |
Gets the global face height for the face.
If the face is scalable this returns the height of the global bounding box which ensures that any glyph will be less than or equal to this height. If the font isn't scalable there is no guarantee that glyphs will not be taller than this value.

| float FTSize::Width | ( | ) | const |
Gets the global face width for the face.
If the face is scalable this returns the width of the global bounding box which ensures that any glyph will be less than or equal to this width. If the font isn't scalable this value is the max_advance for the face.
