Class Type2OutlineParser

java.lang.Object

com.adobe.fontengine.font.cff.Type2OutlineParser

public final class Type2OutlineParser
extends java.lang.Object

Extract the unhinted bezier outlines from a Type2 charstring. A Type2OutlineParser offers a single method, parse which is given a charstring and an OutlineConsumer. As the lines and curves of the charstring are parsed, the OutlineConsumer is called.

The same Type2OutlineParser object can be used repeatedly to extract outlines. The successive invocations do not need to be for the same font (not even in the same fontset), nor do they need to use the same consumer.

The consumer must not call parse on the Type2OutlineParser that invoked it.

Synchronization

This class is not synchronized. Multiple instances can safely coexist without threadsafety issues, but each must only be accessed from one thread (or must be guarded by the client). The parse method invokes the OutlineConsumer on the thread on which it is called.

Constructor Detail

Type2OutlineParser

public Type2OutlineParser(boolean hintedOutlines)

Create a new Type2OutlineParser.

Parameters:

hintedOutlines - True if the outlineConsumers passed to parse will be implementations of HintedOutlineConsumer. False if they will be implementations of OutlineConsumer.

Method Detail

parse

public void parse(CharStrings charStrings,
                  int index,
                  CharStrings localSubrs,
                  CharStrings globalSubrs,
                  OutlineConsumer outlineConsumer,
                  Matrix m,

           throws InvalidFontException,
                  UnsupportedFontException

Parse the outlines of a Type2 charstring.

Parameters:

charStrings - the CharStrings containing the charstring

index - the index of the charctstring in charStrings

localSubrs - the local subroutines

globalSubrs - the global subroutines

outlineConsumer - the OutlineConsumer to alert of the parsing events

m - the Matrix to be applied to the outlines in order to get to a 1 ppem outline

font - the font to use to resolve seac operators

Throws:

InvalidFontException - the charstring is malformed

UnsupportedFontException
