Detailed Description

Typedef Documentation

typedef struct PDCMap* PDCMapRef

A CID mapping.

CID mappings are currently used to deal with ToUnicode streams but have more functionality in PDFs beyond this.

typedef struct PDFontDictionary* PDFontDictionaryRef

A font dictionary.

Font dictionaries are convenience-dictionaries for dealing with font dictionaries in PDF files.

typedef struct PDFont* PDFontRef

A font.

Fonts are objects which contain information on how to convert text to unicode (among other things), necessary to perform text extraction.

typedef void(* PDHashIterator) (char *key, void *value, void *userInfo, PDBool *shouldStop)

Hash iterator signature.

An iterator will walk over all inserted items in a hash map. For each item, the iterator is called with the key and value pair as arguments, as well as an optional user info object.

If *shouldStop is set to true, iteration will end even if there are more items.

typedef struct PDSplayTree* PDSplayTreeRef

A binary splay tree implementation.
