Constructor and Description
CMapAwareDocumentFont(PdfDictionary font)
CMapAwareDocumentFont(PRIndirectReference refFont) Creates an instance of a CMapAwareFont based on an indirect reference to a font.

Method Summary

Modifier and Type	Method and Description
String	decode(byte[] cidbytes, int offset, int len) Decodes a string of bytes (encoded in the font's encoding) into a unicode string This will use the ToUnicode map of the font, if available, otherwise it uses the font's encoding
String	encode(byte[] bytes, int offset, int len) Deprecated. method name is not indicative of what it does. Use decode instead.
int	getWidth(int char1) Gets the width of a char in normalized 1000 units.

Parameters:

refFont - the indirect reference to a font

Method Detail

getWidth

public int getWidth(int char1)

Description copied from class: DocumentFont

Gets the width of a char in normalized 1000 units.

Overrides:

getWidth in class DocumentFont

Parameters:

char1 - the unicode char to get the width of

Returns:

the width in normalized 1000 units

Parameters:

cidbytes - the bytes that need to be decoded

Returns:

the unicode String that results from decoding

Since:
