Variety (UB)

The interpretation of this field depends on the value of the preceding

(Font Scaling Technology) byte. For TrueType fonts, this field must be

set to zero.

OR Threshold (UI)

Formerly called the “LRE Threshold,” this is the pixel size in design

units above which the missing pixel recovery process is switched on

in Intellifont scaling and rasterization.

Note The size of a pixel (in design units) increases as point size and device

resolution decrease.

Global Italic Angle (SI)

The Global Italic Angle field contains the tangent of the italic angle

times 2

(relative to the vertical). Set this field to zero for upright

fonts. For detailed information on Global Italic Angle, refer to Intellifont

Scalable Typeface Format.

Global Intellifont Data Size (UI)

The Global Intellifont Data Size identifies the size of the Global

Intellifont data block. For detailed information about Global Intellifont

Data Size, refer to Intellifont Scalable Typeface Format.

Global Intellifont Data

For detailed information on Global Intellifont Data refer to Intellifont

Scalable Typeface Format.

Character Complement (Array of UB)

This 8-byte field qualifies the compatibility of a type 10 or 11 font with

various character sets. Each bit is independently interpreted with the

exception of the least significant three bits. (Bit 63 refers to the most

significant bit of the first byte, and bit 0 refers to the least significant bit

of the eighth byte.)
