HP 5961-0509 Variety UB, Or Threshold UI, Global Italic Angle SI, Global Intellifont Data Size UI

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 215 (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.)
