Description

Functions

PopplerMediaSaveFunc ()

gboolean
(*PopplerMediaSaveFunc) (const gchar *buf,
                         gsize count,
                         gpointer data,
                         GError **error);

Specifies the type of the function passed to poppler_media_save_to_callback(). It is called once for each block of bytes that is "written" by poppler_media_save_to_callback(). If successful it should return TRUE. If an error occurs it should set error and return FALSE, in which case poppler_media_save_to_callback() will fail with the same error.

Parameters

buf

buffer containing bytes to be written.

[array length=count][element-type guint8]

count

number of bytes in buf .

 

data

user data passed to poppler_media_save_to_callback().

[closure]

error

GError to set on error, or NULL

 

Returns

TRUE if successful, FALSE (with error set) if failed.

Since: 0.14


poppler_media_get_filename ()

const gchar *
poppler_media_get_filename (PopplerMedia *poppler_media);

Returns the media clip filename, in case of non-embedded media. filename might be a local relative or absolute path or a URI

Parameters

poppler_media

a PopplerMedia

 

Returns

a filename, return value is owned by PopplerMedia and should not be freed

Since: 0.14


poppler_media_get_mime_type ()

const gchar *
poppler_media_get_mime_type (PopplerMedia *poppler_media);

Returns the media clip mime-type

Parameters

poppler_media

a PopplerMedia

 

Returns

the mime-type, return value is owned by PopplerMedia and should not be freed

Since: 0.14


poppler_media_is_embedded ()

gboolean
poppler_media_is_embedded (PopplerMedia *poppler_media);

Whether the media clip is embedded in the PDF. If the result is TRUE, the embedded stream can be saved with poppler_media_save() or poppler_media_save_to_callback() function. If the result is FALSE, the media clip filename can be retrieved with poppler_media_get_filename() function.

Parameters

poppler_media

a PopplerMedia

 

Returns

TRUE if media clip is embedded, FALSE otherwise

Since: 0.14


poppler_media_save ()

gboolean
poppler_media_save (PopplerMedia *poppler_media,
                    const char *filename,
                    GError **error);

Saves embedded stream of poppler_media to a file indicated by filename . If error is set, FALSE will be returned. Possible errors include those in the G_FILE_ERROR domain and whatever the save function generates.

Parameters

poppler_media

a PopplerMedia

 

filename

name of file to save

 

error

return location for error, or NULL.

[allow-none]

Returns

TRUE, if the file successfully saved

Since: 0.14


poppler_media_save_to_callback ()

gboolean
poppler_media_save_to_callback (PopplerMedia *poppler_media,
                                PopplerMediaSaveFunc save_func,
                                gpointer user_data,
                                GError **error);

Saves embedded stream of poppler_media by feeding the produced data to save_func . Can be used when you want to store the media clip stream to something other than a file, such as an in-memory buffer or a socket. If error is set, FALSE will be returned. Possible errors include those in the G_FILE_ERROR domain and whatever the save function generates.

Parameters

poppler_media

a PopplerMedia

 

save_func

a function that is called to save each block of data that the save routine generates.

[scope call]

user_data

user data to pass to the save function.

 

error

return location for error, or NULL.

[allow-none]

Returns

TRUE, if the save successfully completed

Since: 0.14
