static public array SetaPDF_Core_Font_Cmap::$namedInstances = array()

Cache for named instances.


Properties

$_cidMap

A separate CMAP instance of only CID mappings.

$_codeSpaceRanges

protected array SetaPDF_Core_Font_Cmap::$_codeSpaceRanges = array()

Code space ranges.

$_lookUps

protected array SetaPDF_Core_Font_Cmap::$_lookUps = array(...)

Resolved data for an optimization of a reverse lookup.

CID and uncidoe mappings.

$_name

protected string SetaPDF_Core_Font_Cmap::$_name

The name resolved from the CMAP file.


Static Methods

_ensureCMapInstance()

protected static SetaPDF_Core_Font_Cmap::_ensureCMapInstance (
mixed &$cmap
): void

Helper method that ensures an instance of self.

Parameters
$cmap : mixed
 
Exceptions

Throws SetaPDF_Core_Font_Exception

_readValue()

protected static SetaPDF_Core_Font_Cmap::_readValue (): array|string

Read the next value via the tokenizer instance.

Parameters
$tokenizer : SetaPDF_Core_Tokenizer
 

cleanUpNamedInstanceCache()

public static SetaPDF_Core_Font_Cmap::cleanUpNamedInstanceCache (
[ string|null $name = null ]
): void

Remove named cmap instances from the local cache.

Parameters
$name : string|null

The name or null for all cached instances

create()

Create an instance based on CMAP data through an reader instance.

Parameters
$reader : SetaPDF_Core_Reader_ReaderInterface
 

createNamed()

public static SetaPDF_Core_Font_Cmap::createNamed (
$name [, bool $cache = false ]
): mixed|null|SetaPDF_Core_Font_Cmap

Creates an instance of an existing CMAP.

Existing CMAPs can be found in /SetaPDF/Font/Cmap/_cmaps/. A named instance will be cached. To remove it from memory you will need to call SetaPDF_Core_Font_Cmap::cleanUpNamedInstanceCache().

Parameters
$name
 
$cache : bool

Lookup by a type.

Parameters
$type : string
 
$src : string
 

_reverseLookup()

protected SetaPDF_Core_Font_Cmap::_reverseLookup (
string $dest, string $type
): bool|number|string

Do a reverse lookup by a specific type.

Parameters
$dest : string
 
$type : string

integer $src1, integer $src2, string $dst, integer $size
): void

Add a cid range mapping.

Parameters
