Method Detail

getCOSObject

public COSStream getCOSObject()

Description copied from interface: COSObjectable

Convert this standard java object to a COS object.

Specified by:

getCOSObject in interface COSObjectable

Returns:

The cos object that matches this Java object.

getFont

public PDType3Font getFont()

getContentStream

public PDStream getContentStream()

getContents

public java.io.InputStream getContents()
                                throws java.io.IOException

Description copied from interface: PDContentStream

Returns this stream's content, if any.

Specified by:

getContents in interface PDContentStream

Returns:

An InputStream or null.

Throws:

java.io.IOException - If the stream could not be read

getContentsForRandomAccess

public RandomAccessRead getContentsForRandomAccess()
                                            throws java.io.IOException

Description copied from interface: PDContentStream

Returns this stream's content, if any.

Specified by:

getContentsForRandomAccess in interface PDContentStream

Returns:

A RandomAccessRead or null.

Throws:

java.io.IOException - If the content could not be read

getResources

getWidth

public float getWidth()
               throws java.io.IOException

Get the width from a type3 charproc stream.

Returns:

the glyph width.

Throws:

java.io.IOException - if the stream could not be read, or did not have d0 or d1 as first operator, or if their first argument was not a number.
