TFontCache.FontHeight

property FontHeight: double;

FontHeight is the font's height in pixels. It's left up to the user to scale font heights appropriately with respect to the target screen's resolution.

When fontHeight = 0, glyphs will be returned according to the font's design height. The font's design height is specified as UnitsPerEm (typically >= 1000) that can be found in the TFontReader's FontInfo property.

Note 1: FontHeight is different to LineHeight. (LineHeight is usually about 25% larger than FontHeight.)

Note 2: changing this property will empty the cache. Consequently, if it's likey that this font and height will be reused, it's advisable to create and use an extra TFontCache.
