RealFont

The RealFont function determines whether a font is available or is intended for use in a specified size.

FUNCTION RealFont (fontNum: Integer; size: Integer): Boolean;

fontNum

The font family ID.

size

The font size requested.

DESCRIPTION

The RealFont function returns TRUE if the requested size of a font is available. RealFont first checks for a bitmapped font from the specified family. If one is not available, RealFont checks next for an outline font. If neither kind of font is available, RealFont returns FALSE.

If an outline font exists for the requested font family, RealFont normally considers the font to be available in any requested size; however, the font designer can include instructions in the font that outlines should not be used at certain point sizes, in which case the RealFont function will consider the font unavailable and return FALSE. The Font Manager determines whether the size is valid by testing the value of the smallest readable size element of the font family header table, which is described in "The Font Header Table," beginning on page 4-74.
