All Implemented Interfaces:

GlyphDescription

public class GlyfCompositeDescript
extends GlyfDescript

Glyph description for composite glyphs. Composite glyphs are made up of one or more simple glyphs, usually with some sort of transformation applied to each. This class is based on code from Apache Batik a subproject of Apache XMLGraphics. see http://xmlgraphics.apache.org/batik/ for further details.

Constructor Detail

GlyfCompositeDescript

GlyfCompositeDescript(TTFDataStream bais,
                      GlyphTable glyphTable,
                      int level)
               throws java.io.IOException

Constructor.

Parameters:

bais - the stream to be read

glyphTable - the Glyphtable containing all glyphs

level - current level

Throws:

java.io.IOException - is thrown if something went wrong

Method Detail

resolve

public void resolve()

Resolve all parts of an composite glyph.

Specified by:

resolve in interface GlyphDescription

Overrides:

resolve in class GlyfDescript

getEndPtOfContours

public int getEndPtOfContours(int i)

Returns the index of the ending point of the given contour.

Parameters:

i - the number of the contour

Returns:

the index of the ending point of the given contour

getFlags

public byte getFlags(int i)

Returns the flags of the given point. To decode these bit flags, use the static elements of GlyfDescript. See also "Outline flags" in The 'glyf' table in the TrueType Reference Manual.

Parameters:

i - the given point

Returns:

the flags value for the given point

getXCoordinate

public short getXCoordinate(int i)

Returns the x coordinate of the given point.

Parameters:

i - the given point

the x coordinate value for the given point

getYCoordinate

public short getYCoordinate(int i)

Returns the y coordinate of the given point.

Parameters:

i - the given point

Returns:

the y coordinate value for the given point

isComposite

public boolean isComposite()

Returns whether this point is a composite or not.

Returns:

true if this point is a composite

getPointCount

public int getPointCount()

Returns the number of points.

Returns:

the number of points

getContourCount

public int getContourCount()

Returns the number of contours.

Specified by:

getContourCount in interface GlyphDescription

Overrides:

getContourCount in class GlyfDescript

Returns:

the number of contours

getComponentCount

public int getComponentCount()

Get number of components.

Returns:

the number of components

getComponents

public java.util.List<GlyfCompositeComp> getComponents()
