Static Methods

freeCache()

WARNING: This method is marked as deprecated!

Call SetaPDF_Core_Document::clearCache() with the type SetaPDF_Core_Document::CACHE_FONT instead.

public static SetaPDF_Core_Font::freeCache (): void

Release font instances by a document instance.

Parameters
$document : SetaPDF_Core_Document
 

freeFontCache()

WARNING: This method is marked as deprecated!

public static SetaPDF_Core_Font::freeFontCache (): void

Release font instances by a document instance.

Parameters

See

get()

public static SetaPDF_Core_Font::get (): SetaPDF_Core_Font|SetaPDF_Core_Font_Cid

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|SetaPDF_Core_Type_Dictionary
 
Exceptions

Throws SetaPDF_Exception_NotImplemented

Calculates the underline thickness.

This method is only used if no underline thickness is provided by the font implementation (e.g. through an already embedded font).
