\Zend_Pdf_Cmap_ByteEncoding_Static

Package: Zend\Pdf\Fonts
Custom cmap type used for the Adobe Standard 14 PDF fonts.

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

Properties

>VPropertyprotectedarray $_glyphIndexArray = array()
inherited
Glyph index array.
Inherited from: \Zend_Pdf_Cmap_ByteEncoding::$$_glyphIndexArray

Stores the actual glyph numbers. The array keys are the translated Unicode code points.

Methods

methodpublic__construct(array $cmapData) : void

Object constructor

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

Parameters
NameTypeDescription
$cmapDataarray

Array whose keys are Unicode character codes and values are glyph numbers.

Throws
ExceptionDescription
\Zend_Pdf_Exception
methodprotected_extractInt2(string $data, integer $index) : integer
inherited

Extracts a signed 2-byte integer from a string.

Inherited from: \Zend_Pdf_Cmap::_extractInt2()\Zend_Pdf_Cmap_ByteEncoding::_extractInt2()

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

Parameters
NameTypeDescription
$datastring

&$data

$indexinteger

Position in string of integer.

Returns
TypeDescription
integer
Throws
ExceptionDescription
\Zend_Pdf_Exception
methodprotected_extractUInt2(string $data, integer $index) : integer
inherited

Extracts an unsigned 2-byte integer from a string.

Inherited from: \Zend_Pdf_Cmap::_extractUInt2()\Zend_Pdf_Cmap_ByteEncoding::_extractUInt2()

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

Parameters
NameTypeDescription
$datastring

&$data

$indexinteger

Position in string of integer.

Returns
TypeDescription
integer
Throws
ExceptionDescription
\Zend_Pdf_Exception
methodprotected_extractUInt4(string $data, integer $index) : integer
inherited

Extracts an unsigned 4-byte integer from a string.

Inherited from: \Zend_Pdf_Cmap::_extractUInt4()\Zend_Pdf_Cmap_ByteEncoding::_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
NameTypeDescription
$datastring

&$data

$indexinteger

Position in string of integer.

Returns
TypeDescription
integer
Throws
ExceptionDescription
\Zend_Pdf_Exception
methodpubliccmapWithTypeData(integer $cmapType, mixed $cmapData) : \Zend_Pdf_Cmap
staticinherited

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

Inherited from: \Zend_Pdf_Cmap::cmapWithTypeData()\Zend_Pdf_Cmap_ByteEncoding::cmapWithTypeData()
Parameters
NameTypeDescription
$cmapTypeinteger

Type of cmap.

$cmapDatamixed

Cmap table data. Usually a string or array.

Returns
TypeDescription
\Zend_Pdf_Cmap
Throws
ExceptionDescription
\Zend_Pdf_Exception
methodpublicgetCoveredCharacters() : array
inherited

Inherited from: \Zend_Pdf_Cmap_ByteEncoding::getCoveredCharacters()
Returns
TypeDescription
arrayUnicode character codes.
methodpublicglyphNumberForCharacter(integer $characterCode) : integer
inherited

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 glyphNumbersForCharacters() which is optimized for bulk operations.

Parameters

inherited

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 glyphNumberForCharacter().

Parameters
