Method Detail

checkCharProcsAndMetrics	back to summary
private void checkCharProcsAndMetrics() CharProcs is a dictionary where the key is a character name and the value is a Stream which contains the glyph representation of the key. This method checks that all characters codes defined in the Widths Array exist in the CharProcs dictionary. If the CharProcs doesn't know the Character, it is mapped with the .notdef one. For each character, the Glyph width must be the same as the Width value declared in the Widths array.

private void checkCharProcsAndMetrics()

CharProcs is a dictionary where the key is a character name and the value is a Stream which contains the glyph representation of the key. This method checks that all characters codes defined in the Widths Array exist in the CharProcs dictionary. If the CharProcs doesn't know the Character, it is mapped with the .notdef one. For each character, the Glyph width must be the same as the Width value declared in the Widths array.

checkEncoding	back to summary
protected void checkEncoding() Overrides org.apache.pdfbox.preflight.font.FontValidator.checkEncoding. For a Type3 font, the mapping between the Character Code and the Character name is entirely defined in the /Encoding entry. The /Encoding Entry can be a Name (For the 5 predefined encodings) or a dictionary. If it is a dictionary, the /Differences array contains the correspondence between a character code and a set of character name which are different from the encoding entry of the dictionary. This method checks that the encoding is : An existing encoding name. A dictionary with an existing encoding name (the name is optional) and a well formed "Differences" array (the array is optional) Annotations @Override
