\Zend_Pdf_Cmap_ByteEncoding_Static

Custom cmap type used for the Adobe Standard 14 PDF fonts.

Just like {@link Zend_Pdf_Cmap_ByteEncoding} except that the constructor takes a predefined array of glyph numbers and can cover any Unicode character.

Methods

methodpublic__construct( array $cmapData ) : void

Object constructor

Parses the raw binary table data. Throws an exception if the table is malformed.

Parameters
Name Type Description
$cmapData array Array whose keys are Unicode character codes and values are glyph numbers.
Throws
Exception Description
\Zend_Pdf_Exception
methodprotected_extractInt2( string $data, integer $index ) : integer

Extracts a signed 2-byte integer from a string.

Inherited from: \Zend_Pdf_Cmap::_extractInt2()

Integers are always big-endian. Throws an exception if the index is out of range.

Parameters
Name Type Description
$data string

&$data

$index integer Position in string of integer.
Returns
Type Description
integer
Throws
Exception Description
\Zend_Pdf_Exception
methodprotected_extractUInt2( string $data, integer $index ) : integer

Extracts an unsigned 2-byte integer from a string.

Inherited from: \Zend_Pdf_Cmap::_extractUInt2()

Integers are always big-endian. Throws an exception if the index is out of range.

Parameters
Name Type Description
$data string

&$data

$index integer Position in string of integer.
Returns
Type Description
integer
Throws
Exception Description
\Zend_Pdf_Exception
methodprotected_extractUInt4( string $data, integer $index ) : integer

Extracts an unsigned 4-byte integer from a string.

Inherited from: \Zend_Pdf_Cmap::_extractUInt4()

Integers are always big-endian. Throws an exception if the index is out of range.

NOTE: If you ask for a 4-byte unsigned integer on a 32-bit machine, the resulting value WILL BE SIGNED because PHP uses signed integers internally for everything. To guarantee portability, be sure to use bitwise or similar operators on large integers!

Parameters
Name Type Description
$data string

&$data

$index integer Position in string of integer.
Returns
Type Description
integer
Throws
Exception Description
\Zend_Pdf_Exception
methodpubliccmapWithTypeData( integer $cmapType, mixed $cmapData ) : \Zend_Pdf_Cmap
static

Instantiates the appropriate concrete subclass based on the type of cmap table and returns the instance.

Inherited from: \Zend_Pdf_Cmap::cmapWithTypeData()

The cmap type must be one of the following values:

  • {@link Zend_Pdf_Cmap::TYPE_BYTE_ENCODING}
  • {@link Zend_Pdf_Cmap::TYPE_BYTE_ENCODING_STATIC}
  • {@link Zend_Pdf_Cmap::TYPE_HIGH_BYTE_MAPPING}
  • {@link Zend_Pdf_Cmap::TYPE_SEGMENT_TO_DELTA}
  • {@link Zend_Pdf_Cmap::TYPE_TRIMMED_TABLE}
  • {@link Zend_Pdf_Cmap::TYPE_MIXED_COVERAGE}
  • {@link Zend_Pdf_Cmap::TYPE_TRIMMED_ARRAY}
  • {@link Zend_Pdf_Cmap::TYPE_SEGMENTED_COVERAGE}

Throws an exception if the table type is invalid or the cmap table data cannot be validated.

Parameters
Name Type Description
$cmapType integer Type of cmap.
$cmapData mixed Cmap table data. Usually a string or array.
Returns
Type Description
\Zend_Pdf_Cmap
Throws
Exception Description
\Zend_Pdf_Exception
methodpublicgetCoveredCharacters( ) : array

Returns an array containing the Unicode characters that have entries in this character map.

Inherited from: \Zend_Pdf_Cmap_ByteEncoding::getCoveredCharacters()
Returns
Type Description
array Unicode character codes.
methodpublicglyphNumberForCharacter( integer $characterCode ) : integer

Returns the glyph number corresponding to the Unicode character.

Inherited from: \Zend_Pdf_Cmap_ByteEncoding::glyphNumberForCharacter()

If a particular character doesn't exist in this font, the special 'missing character glyph' will be substituted.

See also {@link glyphNumbersForCharacters()} which is optimized for bulk operations.

Parameters
Name Type Description
$characterCode integer

Unicode character code (code point).

Returns
Type Description
integer Glyph number.
methodpublicglyphNumbersForCharacters( array $characterCodes ) : array

Returns an array of glyph numbers corresponding to the Unicode characters.

Inherited from: \Zend_Pdf_Cmap_ByteEncoding::glyphNumbersForCharacters()

If a particular character doesn't exist in this font, the special 'missing character glyph' will be substituted.

See also {@link glyphNumberForCharacter()}.

Parameters
Name Type Description
$characterCodes array

Array of Unicode character codes (code points).

Returns
Type Description
array Array of glyph numbers.
