Constructor Detail

Type1FontLoader

public Type1FontLoader(FontUris fontUris,
                       boolean embedded,
                       EmbeddingMode embeddingMode,
                       boolean useKerning,
                       InternalResourceResolver resourceResolver)
                throws java.io.IOException

Constructs a new Type 1 font loader.

Parameters:

fontUris - the URI to the PFB file of a Type 1 font

embedded - indicates whether the font is embedded or referenced

useKerning - indicates whether to load kerning information if available

resourceResolver - the font resolver used to resolve URIs

Throws:

java.io.IOException - In case of an I/O error

Method Detail

getPFMURI

private java.lang.String getPFMURI(java.lang.String pfbURI)

read

protected void read()
             throws java.io.IOException

Reads/parses the font data.

Specified by:

read in class FontLoader

Throws:

java.io.IOException - In case of an I/O error

buildFont

private void buildFont(AFMFile afm,
                       PFMFile pfm)

handleEncoding

private void handleEncoding(AFMFile afm,
                            PFMFile pfm)

toGlyphSet

private java.util.Set<java.lang.String> toGlyphSet(java.lang.String[] glyphNames)

addUnencodedBasedOnEncoding

private void addUnencodedBasedOnEncoding(AFMFile afm)

Adds characters not encoded in the font's primary encoding. This method is used when we don't trust the AFM to expose the same encoding as the primary font.

Parameters:

afm - the AFM file.

addUnencodedCharacter

private static void addUnencodedCharacter(SingleByteFont font,
                                          AFMCharMetrics metrics)

addUnencodedBasedOnAFM

private void addUnencodedBasedOnAFM(AFMFile afm)

Adds characters not encoded in the font's primary encoding. This method is used when the primary encoding is built based on the character codes in the AFM rather than the specified encoding (ex. with symbolic fonts).

Parameters:

afm - the AFM file

handleFontName

private void handleFontName(AFMFile afm,
                            PFMFile pfm)

handleMetrics

private void handleMetrics(AFMFile afm,
                           PFMFile pfm)

buildCustomEncoding

private CodePointMapping buildCustomEncoding(java.lang.String encodingName,
                                             AFMFile afm)
