CMap

private String CMap

The CMap name associated with this font

Constructor Detail

CJKFont

CJKFont(String fontName, String enc, boolean emb)

Creates a CJK font.

Parameters: fontName the name of the font enc the encoding of the font emb always false. CJK font and not embedded

Method Detail

charExists

public boolean charExists(int c)

Checks if a character exists in this font.

Parameters: c the character to check

Returns: true if the character has a glyph, false otherwise

convertToHCIDMetrics

static String convertToHCIDMetrics(int[] keys, IntHashtable h)

convertToVCIDMetrics

static String convertToVCIDMetrics(int[] keys, IntHashtable v, IntHashtable h)

createMetric

static IntHashtable createMetric(String s)

Gets all the entries of the names-table. If it is a True Type font each array element will have {Name ID, Platform ID, Platform Encoding ID, Language ID, font name}. The interpretation of this values can be found in the Open Type specification, chapter 2, in the 'name' table.
For the other fonts the array has a single element with {"4", "", "", "", font name}.

Returns: the full name of the font

getDescNumber

private float getDescNumber(String name)

getFamilyFontName

public String[][] getFamilyFontName()

Gets the family name of the font. If it is a True Type font each array element will have {Platform ID, Platform Encoding ID, Language ID, font name}. The interpretation of this values can be found in the Open Type specification, chapter 2, in the 'name' table.
For the other fonts the array has a single element with {"", "", "", font name}.

Returns: the family name of the font

getFontBaseType
