Class CharStringsWidths

java.lang.Object

org.verapdf.pd.font.cff.CharStringsWidths

public class CharStringsWidths
extends Object

This class handles obtaining glyph widths from cff charStrings. If font is a subset, then all charstrings are parsed at initialization, else each charstring is parsed separately in getter.

CharStringsWidths

public CharStringsWidths(boolean isSubset,
                         int charStringType,
                         org.verapdf.pd.font.cff.CFFCharStringsHandler charStrings,

                         CFFIndex[] localSubrIndex,
                         CFFIndex globalSubrs,
                         int[] bias,
                         int[] defaultWidths,
                         int[] nominalWidths,
                         int[] fdSelect)

Initializes handler with given values.

Parameters:

isSubset - is true if font is subset. In this case all widths will be parsed during handler initialization.

charStringType - is type of charstring.

charStrings - is charstring handler with charstring data.

fontMatrices - is array of font matrix for each FDArray element.

localSubrIndex - is array of local subrs for each FDArray element.

globalSubrs - is array of global subrs for each FDArray element.

bias - is array of bias values for each FDArray element.

defaultWidths - is array of default widths for each FDArray element.

nominalWidths - is array of nominal widths for each FDArray element.

fdSelect - is fd select array as specified in CFF font.

                         int defaultWidth,
                         int nominalWidth)

Initializes handler with given values.

Parameters:

isSubset - is true if font is subset. In this case all widths will be parsed during handler initialization.

charStringType - is type of charstring.

charStrings - is charstring handler with charstring data.

fontMatrix - is font matrix for this charstrings.

localSubrIndex - is CFFIndex with local subrs.

globalSubrs - is CFFIndex with global subrs.

bias - is bias value that depends on local subrs size.

defaultWidth - is a default width for this font program.

nominalWidth - is a nominal width for this font program.
