See

get()

Get a font object by an indirect reference.

The needed font object class is automatically resolve via the Subtype value of the font dictionary.

Parameters
$indirectObjectOrDictionary : SetaPDF_Core_Type_IndirectObjectInterface
 
Exceptions

Methods

__construct()

_getEncodingTable()

protected array SetaPDF_Core_Font_Type3::_getEncodingTable ( void )

Get the encoding table based on the Encoding dictionary and it's Differences entry (if available).

_getWidths()

protected void SetaPDF_Core_Font_Type3::_getWidths ( void )

Resolves the width values from the font descriptor and fills the $_width-array.

getAvgWidth()

public integer|float SetaPDF_Core_Font::getAvgWidth ( [ boolean $calculateIfUndefined = false ] )

Get the average glyph width.

Parameters
$calculateIfUndefined : boolean
 

getBaseEncodingTable()

Get the base encoding of the font.

If no BaseEncoding entry is available we use the Standard encoding for now. This should be extended to get the fonts build in encoding later.

Get the final character code of a single character.

Parameters
$char : string

The character

$encoding : string

The output encoding

getCharCodes()

public array SetaPDF_Core_Font::getCharCodes ( string $chars [, string $encoding = 'UTF-16BE' ] )

$encoding : string

The output encoding

getCharsByCharCodes()

public string|array SetaPDF_Core_Font_Type3::getCharsByCharCodes ( string $charCodes [, string $encoding = 'UTF-8' [, bool $asArray = true ]] )
