Summary

Static Properties

$cmapDirectory

static public Cmap::$cmapDirectory = '/app/library/SetaPDF/Core/Font/Cmap/_cmaps'

$namedInstances

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

Cache for named instances.

Properties

$_cidMap

protected Cmap Cmap::$_cidMap

A separate CMAP instance of only CID mappings.

$_codeSpaceRanges

protected array Cmap::$_codeSpaceRanges = array()

Code space ranges.

$_lookUps

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

Resolved data for an optimization of a reverse lookup.

$_mappings

protected array Cmap::$_mappings = array(...)

CID and Unicode mappings.

$_name

protected string Cmap::$_name

The name resolved from the CMAP file.

Static Methods

_ensureCMapInstance()

protected static Cmap::_ensureCMapInstance (

mixed &$cmap

): void

Helper method that ensures an instance of self.

Parameters

$cmap : mixed

_readValue()

protected static Cmap::_readValue (

\setasign\SetaPDF2\Core\Tokenizer $tokenizer

): array|string|false

Read the next value via the tokenizer instance.

Parameters

$tokenizer : \setasign\SetaPDF2\Core\Tokenizer

cleanUpNamedInstanceCache()

public static Cmap::cleanUpNamedInstanceCache (

?string $name = null

): void

Remove named cmap instances from the local cache.

Parameters

$name : ?string: The name or null for all cached instances

create()

public static Cmap::create (

\setasign\SetaPDF2\Core\Reader\ReaderInterface $reader

): ?Cmap

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

Parameters

$reader : \setasign\SetaPDF2\Core\Reader\ReaderInterface

Exceptions

Throws \setasign\SetaPDF2\Core\Font\Exception

createNamed()

public static Cmap::createNamed (

string $name,
bool $cache = false

): mixed|null|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 Cmap ::cleanUpNamedInstanceCache().

Parameters

$name : string
$cache : bool: This parameter will write a serialized version into the cmaps folder.

Exceptions

Throws \setasign\SetaPDF2\Core\Font\Exception
