Routines / Enabling Fractional Glyph Widths

SetFractEnable

The SetFractEnable procedure enables or disables fractional glyph widths.

PROCEDURE SetFractEnable (fractEnable: Boolean);

fractEnable

Specifies whether fractional widths or integer widths are to be used to determine glyph measurements. A value of TRUE indicates fractional glyph widths; a value of FALSE indicates integer glyph widths.

DESCRIPTION

The SetFractEnable procedure establishes whether or not the Font Manager provides fractional glyph widths to QuickDraw, which then uses them for advancing the pen during text drawing. If you set the fractEnable parameter to TRUE, the Font Manager provides fractional glyph widths. If you set it to FALSE, the Font Manager provides integer glyph widths.

The SetFractEnable procedure assigns the value that you specify in the fractEnable parameter to the global variable FractEnable.

The Font Manager defaults to integer widths to ensure compatibility with existing applications.
