Method Detail

getSyllabizerClass

protected java.lang.Class<? extends org.apache.fop.complexscripts.scripts.GurmukhiScriptProcessor.GurmukhiSyllabizer> getSyllabizerClass()

Description copied from class: IndicScriptProcessor

Get script specific syllabizer class.

Overrides:

getSyllabizerClass in class IndicScriptProcessor

Returns:

a syllabizer class object or null

findPreBaseMatra

protected int findPreBaseMatra(GlyphSequence gs)

Description copied from class: IndicScriptProcessor

Find pre-base matra in sequence.

Overrides:

findPreBaseMatra in class IndicScriptProcessor

Parameters:

gs - input sequence

Returns:

index of pre-base matra or -1 if not found

findPreBaseMatraTarget

protected int findPreBaseMatraTarget(GlyphSequence gs,
                         int source)

Description copied from class: IndicScriptProcessor

Find pre-base matra target in sequence.

Overrides:

findPreBaseMatraTarget in class IndicScriptProcessor

Parameters:

gs - input sequence

source - index of pre-base matra

Returns:

index of pre-base matra target or -1

findReph

protected int findReph(GlyphSequence gs)

Description copied from class: IndicScriptProcessor

Find reph in sequence.

Overrides:

findReph in class IndicScriptProcessor

Parameters:

gs - input sequence

Returns:

index of reph or -1 if not found

findRephTarget

protected int findRephTarget(GlyphSequence gs,
                 int source)

Description copied from class: IndicScriptProcessor

Find reph target in sequence.

Overrides:

findRephTarget in class IndicScriptProcessor

Parameters:

gs - input sequence

source - index of reph

Returns:

index of reph target or -1

reorderCombiningMarks

public GlyphSequence reorderCombiningMarks(GlyphDefinitionTable gdef,
                                  GlyphSequence gs,
                                  int[][] gpa,
                                  java.lang.String script,
                                  java.lang.String language)

Description copied from class: ScriptProcessor

Reorder combining marks in glyph sequence so that they precede (within the sequence) the base character to which they are applied. N.B. In the case of RTL segments, marks are not reordered by this, method since when the segment is reversed by BIDI processing, marks are automatically reordered to precede their base glyph.

Overrides:

reorderCombiningMarks in class DefaultScriptProcessor

Parameters:

gdef - the glyph definition table that applies

gs - an input glyph sequence

gpa - associated glyph position adjustments (also reordered)

script - a script identifier

language - a language identifier

Returns:

the reordered (output) glyph sequence
