Implements the "byte encoding" character map (type 0).
This is the (legacy) Apple standard encoding mechanism and provides coverage for characters in the Mac Roman character set only. Consequently, this cmap type should be used only as a last resort.
The mapping from Mac Roman to Unicode can be found at {@link http://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/ROMAN.TXT}.

__construct(
string $cmapData
)
:
void
Object constructor
Parses the raw binary table data. Throws an exception if the table is malformed.
Name | Type | Description |
---|---|---|
$cmapData | string | Raw binary cmap table data. |
Exception | Description |

\Zend_Pdf_Exception |

_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.
Name | Type | Description |
---|---|---|
$data | string | &$data |
$index | integer | Position in string of integer. |
Type | Description |
---|---|
integer |
Exception | Description |
---|---|
\Zend_Pdf_Exception |

_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.
Name | Type | Description |
---|---|---|
$data | string | &$data |
$index | integer | Position in string of integer. |
Type | Description |
---|---|
integer |
Exception | Description |

\Zend_Pdf_Exception |

_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!
Name | Type | Description |
---|---|---|
$data | string | &$data |
$index | integer | Position in string of integer. |
Type | Description |
---|---|
integer |
Exception | Description |

\Zend_Pdf_Exception |

cmapWithTypeData(
integer $cmapType, mixed $cmapData
)
:
\Zend_Pdf_Cmap
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:
Throws an exception if the table type is invalid or the cmap table data cannot be validated.
Name | Type | Description |
---|---|---|
$cmapType | integer | Type of cmap. |

getCoveredCharacters(
)
:
array
Returns an array containing the Unicode characters that have entries in this character map.
Type | Description |
---|---|
array | Unicode character codes. |

glyphNumberForCharacter(
integer $characterCode
)
:
integer
Returns the glyph number corresponding to the Unicode character.
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.

integer | Glyph number. |

glyphNumbersForCharacters(
array $characterCodes
)
:
array
Returns an array of glyph numbers corresponding to the Unicode characters.
If a particular character doesn't exist in this font, the special 'missing character glyph' will be substituted.
See also {@link glyphNumberForCharacter()}.
Name | Type | Description |
