Enclosing class:

XtfGSUBSingleTable

public static class XtfGSUBSingleTable.SingleTableFormat1
extends XtfGSUBSingleTable

SingleTable for format 1.

Format 1 calculates the indices of the output glyphs, which are not explicitly defined in the subtable. To calculate an output glyph index, Format 1 adds a constant delta value to the input glyph index. For the substitutions to occur properly, the glyph indices in the input and output ranges must be in the same order. This format does not use the Coverage Index that is returned from the Coverage table. The SingleSubstFormat1 subtable begins with a format identifier (SubstFormat) of 1. An offset references a Coverage table that specifies the indices of the input glyphs.

DeltaGlyphID is the constant value added to each input glyph index to calculate the index of the corresponding output glyph.
