Package: Zend_Pdf\Fonts

Abstract factory class which vends {@link Zend_Pdf_Resource_Font} objects.

Font objects themselves are normally instantiated through the factory methods {@link fontWithName()} or {@link fontWithPath()}. This class is also the home for font-related constants because the name of the true base class ({@link Zend_Pdf_Resource_Font}) is not intuitive for the end user.

Methods

_extractTrueTypeFont(\Zend_Pdf_FileParserDataSource $dataSource, integer $embeddingOptions) : \Zend_Pdf_Resource_Font_OpenType_TrueType

static

Attempts to extract a TrueType font from the data source.

If the font parser throws an exception that suggests the data source simply doesn't contain a TrueType font, catches it and returns null. If an exception is thrown that suggests the TrueType font is corrupt or otherwise unusable, throws that exception. If successful, returns the font object.

Parameters

Name	Type	Description
$dataSource	\Zend_Pdf_FileParserDataSource
$embeddingOptions	integer	Options for font embedding.

Returns

Type	Description
\Zend_Pdf_Resource_Font_OpenType_TrueType	May also return null if the data source does not appear to contain a TrueType font.

Throws

Exception	Description
\Zend_Pdf_Exception

fontWithName(string $name, integer $embeddingOptions = 0) : \Zend_Pdf_Resource_Font

static

Returns a {@link Zend_Pdf_Resource_Font} object by full name.

This is the preferred method to obtain one of the standard 14 PDF fonts. The result of this method is cached, preventing unnecessary duplication of font objects. Repetitive calls for a font with the same name will return the same object. The $embeddingOptions parameter allows you to set certain flags related to font embedding. You may combine options by OR-ing them together. See the EMBED_ constants defined in {@link Zend_Pdf_Font} for the list of available options and their descriptions. Note that this value is only used when creating a font for the first time. If a font with the same name already exists, you will get that object and the options you specify here will be ignored. This is because fonts are only embedded within the PDF file once. If the font name supplied does not match the name of a previously instantiated object and it is not one of the 14 standard PDF fonts, an exception will be thrown.

Parameters

Name	Type	Description
$name	string	Full PostScript name of font.
$embeddingOptions	integer	(optional) Options for font embedding.

Returns

Type	Description
\Zend_Pdf_Resource_Font

Throws

Exception	Description
\Zend_Pdf_Exception

fontWithPath(string $filePath, integer $embeddingOptions = 0) : \Zend_Pdf_Resource_Font

static

Returns a {@link Zend_Pdf_Resource_Font} object by file path.

The result of this method is cached, preventing unnecessary duplication of font objects. Repetitive calls for the font with the same path will return the same object. The $embeddingOptions parameter allows you to set certain flags related to font embedding. You may combine options by OR-ing them together. See the EMBED_ constants defined in {@link Zend_Pdf_Font} for the list of available options and their descriptions. Note that this value is only used when creating a font for the first time. If a font with the same name already exists, you will get that object and the options you specify here will be ignored. This is because fonts are only embedded within the PDF file once. If the file path supplied does not match the path of a previously instantiated object or the font type cannot be determined, an exception will be thrown.

Parameters

Name	Type	Description
$filePath	string	Full path to the font file.
$embeddingOptions	integer	(optional) Options for font embedding.

Returns

Type	Description
\Zend_Pdf_Resource_Font

Throws

Exception	Description
\Zend_Pdf_Exception
