Enclosing class:

public static class XtfGPOSSingleTable.SingleTableFormat1
extends XtfGPOSSingleTable
implements XMLWriterConvertible

SingleTable for format 1.

Single Adjustment Positioning: Format 1

A SinglePosFormat1 subtable applies the same positioning value or values to each glyph listed in its Coverage table. For instance, when a font uses old-style numerals, this format could be applied to uniformly lower the position of all math operator glyphs.

The Format 1 subtable consists of a format identifier (PosFormat), an offset to a Coverage table that defines the glyphs to be adjusted by the positioning values (Coverage), and the format identifier (ValueFormat) that describes the amount and kinds of data in the ValueRecord.

The ValueRecord specifies one or more positioning values to be applied to all covered glyphs (Value). For example, if all glyphs in the Coverage table require both horizontal and vertical adjustments, the ValueRecord will specify values for both XPlacement and Yplacement.

SinglePosFormat1 subtable: Single positioning value

Value	Type	Description
uint16	PosFormat	Format identifier-format = 1
Offset	Coverage	Offset to Coverage table-from beginning of SinglePos subtable
uint16	ValueFormat	Defines the types of data in the ValueRecord
ValueRecord	Value	Defines positioning value(s)-applied to all glyphs in the Coverage table
