fontParser

private Type1Parser fontParser

characterSet

private String characterSet

kernPairs

private Map<Long,Integer> kernPairs

Represents the section KernPairs in the AFM file. Key is uni1 << 32 + uni2. Value is kerning value.

PFB_TYPES

private static final int[] PFB_TYPES

Types of records in a PFB file. ASCII is 1 and BINARY is 2. They have to appear in the PFB file in this sequence.

fontStreamBytes

private byte[] fontStreamBytes

fontStreamLengths

private int[] fontStreamLengths

initializeGlyphs

public void initializeGlyphs(FontEncoding fontEncoding)

Fills missing character codes in codeToGlyph map.

Parameters:

fontEncoding - to be used to map unicode values to character codes.

isBuiltInFont

public boolean isBuiltInFont()

getPdfFontFlags

public int getPdfFontFlags()

Specified by:

getPdfFontFlags in class FontProgram

getCharacterSet

public String getCharacterSet()

hasKernPairs

public boolean hasKernPairs()

Checks if the font has any kerning pairs.

Overrides:

hasKernPairs in class FontProgram

Returns:

true if the font has any kerning pairs.

getKerning

public int getKerning(Glyph first,
 Glyph second)

Description copied from class: FontProgram

Gets the kerning between two glyphs.

Specified by:

getKerning in class FontProgram

Parameters:

first - the first glyph

second - the second glyph

Returns:
