Parameters:

gid - the glyph id of the glyph

consumer - the OutlineConsumer to receive the outline

Throws:

getOutline

public void getOutline(int gid,
 Type2OutlineParser parser,
 OutlineConsumer consumer)
                throws InvalidFontException,

getFontMatrix

public Matrix getFontMatrix()

Specified by:

getFontMatrix in class CFFFont

getFontMatrix

public Matrix getFontMatrix(int component)

Allows recover of concatenated font matrix from a CID component.

getHorizontalAdvance

public double getHorizontalAdvance(int gid)
                            throws InvalidFontException,
UnsupportedFontException

Get the horizontal advance of a glyph. The returned value is in metric space.

Specified by:

                                   throws UnsupportedFontException,
InvalidFontException

Emulates the CoolType API CTFontDict:GetHorizontalMetrics CoolType API.

The metrics are expressed in the design space of the font, i.e. they need to be converted through the metrics matrix.

This methods never returns null.

See also the FontData.getLineMetrics() method.

Specified by:

getCoolTypeLineMetrics in class FontData

Throws:

UnsupportedFontException
