Detailed Description

Helper implementation of album_art_extractor - reads album art from arbitrary file formats that comply with APEv2 tagging specification.

Definition at line 53 of file album_art_helpers.h.

Constructor & Destructor Documentation

album_art_extractor_impl_stdtags::album_art_extractor_impl_stdtags ( const char *  exts )

inline

Parameters

exts	Semicolon-separated list of file format extensions to support.

Definition at line 56 of file album_art_helpers.h.

                                                        {
        pfc::splitStringSimple_toList(m_extensions,';',exts);
    }

Member Function Documentation

bool album_art_extractor_impl_stdtags::is_our_path ( const char *  p_path, const char *  p_extension  )

inlinevirtual

Returns whether the specified file is one of formats supported by our album_art_extractor implementation.

Parameters

p_path	Path to file being queried.
p_extension	Extension of file being queried (also present in p_path parameter) - provided as a separate parameter for performance reasons.

Implements album_art_extractor.

Definition at line 60 of file album_art_helpers.h.

                                                                   {
        return m_extensions.have_item(p_extension);
    }

album_art_extractor_instance_ptr album_art_extractor_impl_stdtags::open ( file_ptr  p_filehint, const char *  p_path, abort_callback &  p_abort  )

inlinevirtual

Instantiates album_art_extractor_instance providing access to album art stored in a specified media file.
Throws one of I/O exceptions on failure; exception_album_art_not_found when the file has no album art record at all.

Parameters

p_filehint

Optional; specifies a file interface to use for accessing the specified file; can be null - in that case, the implementation will open and close the file internally.

Implements album_art_extractor.
