Member Enumeration Documentation

◆ FontFlagsEnum

enum Aspose::Font::TtfTables::TtfHeadTable::FontFlagsEnum : uint16_t

strongprotected

Font flags enumeration.

Enumerator
Bit0	Bit 0: Baseline for font at y=0.
Bit1	Bit 1: Left sidebearing point at x=0 (relevant only for TrueType rasterizers) — see the note below regarding variable fonts.
Bit2	Bit 2: Instructions may depend on point size.
Bit3	Bit 3: Force ppem to integer values for all internal scaler math; may use fractional ppem sizes if this bit is clear. It is strongly recommended that this be set in hinted fonts.
Bit4	Bit 4: Instructions may alter advance width (the advance widths might not scale linearly).
Bit5	Bit 5: This bit is not used in OpenType, and should not be set in order to ensure compatible behavior on all platforms. If set, it may result in different behavior for vertical layout in some platforms. (See Apple’s specification for details regarding behavior in Apple platforms.)
Bit6	Bits 6–10: These bits are not used in Opentype and should always be cleared. (See Apple’s specification for details regarding legacy used in Apple platforms.)
Bit7	Bits 6–10: These bits are not used in Opentype and should always be cleared. (See Apple’s specification for details regarding legacy used in Apple platforms.)
Bit8	Bits 6–10: These bits are not used in Opentype and should always be cleared. (See Apple’s specification for details regarding legacy used in Apple platforms.)
Bit9	Bits 6–10: These bits are not used in Opentype and should always be cleared. (See Apple’s specification for details regarding legacy used in Apple platforms.)
Bit10	Bits 6–10: These bits are not used in Opentype and should always be cleared. (See Apple’s specification for details regarding legacy used in Apple platforms.)
Bit11	Bit 11: Font data is “lossless” as a result of having been subjected to optimizing transformation and/or compression (such as e.g. compression mechanisms defined by ISO/IEC 14496-18, MicroType Express, WOFF 2.0 or similar) where the original font functionality and features are retained but the binary compatibility between input and output font files is not guaranteed. As a result of the applied transform, the DSIG table may also be invalidated.
Bit12	Bit 12: Font converted (produce compatible metrics).
Bit13	Bit 13: Font optimized for ClearType™. Note, fonts that rely on embedded bitmaps (EBDT) for rendering should not be considered optimized for ClearType, and therefore should keep this bit cleared.
Bit14	Bit 14: Last Resort font. If set, indicates that the glyphs encoded in the 'cmap' subtables are simply generic symbolic representations of code point ranges and don’t truly represent support for those code points. If unset, indicates that the glyphs encoded in the 'cmap' subtables represent proper support for those code points.
Bit15	Reserved, set to 0.
