Constructor Detail

GlyphIterator

public GlyphIterator(AttributedCharacterIterator aci,
                     GVTGlyphVector gv)

GlyphIterator

public GlyphIterator(GlyphIterator gi)
Method Detail

copy

public GlyphIterator copy()

copy

public GlyphIterator copy(GlyphIterator gi)

getGlyphIndex

public int getGlyphIndex()
Returns:
The index into glyph vector for current character.

getChar

public char getChar()
Returns:
the current character.

getACIIndex

public int getACIIndex()
Returns:
The index into Attributed Character iterator for current character.

getAdv

public float getAdv()
Returns:
The current advance for the line, this is the 'visual width' of the current line.

getOrigin

public Point2D getOrigin()
Returns:
The origin of the glyph vector (the point all glyphs are layed out with respect to).

getAdj

public float getAdj()
Returns:
The current adjustment for the line. This is the ammount that needs to be subracted from the following line to get it back to the start of the next line.

getMaxFontSize

public float getMaxFontSize()

getMaxAscent

public float getMaxAscent()

getMaxDescent

public float getMaxDescent()

isLastChar

public boolean isLastChar()

done

public boolean done()

isBreakChar

public boolean isBreakChar()

isPrinting

protected boolean isPrinting(char tstCH)

getLineBreaks

public int getLineBreaks()

nextChar

public void nextChar()
Move iterator to the next char.


addLeftShift

protected void addLeftShift(int idx,
                            float chAdv)

updateLineMetrics

protected void updateLineMetrics(int end)

newLine

public LineInfo newLine(Point2D.Float loc,
                        float lineWidth,
                        boolean partial,
                        Point2D.Float verticalAlignOffset)

isPrinting

public boolean isPrinting()

getCharAdvance

public float getCharAdvance()
Get the advance associated with the current glyph


getCharWidth

public float getCharWidth()
Get the visual advance associated with the current glyph. This is the distance from the location of the glyph to the rightmost part of the glyph.


getCharAdvance

protected float getCharAdvance(int gvIdx)
Get the advance associated with any glyph


getCharWidth

protected float getCharWidth(int gvIdx)
Get the visual advance associated with the current glyph. This is the distance from the location of the glyph to the rightmost part of the glyph.
