typedef enum { GMIME_BEST_ENCODING_7BIT, GMIME_BEST_ENCODING_8BIT, GMIME_BEST_ENCODING_BINARY, } GMimeBestEncoding;
GMimeFilter* g_mime_filter_best_new (unsigned int flags);
Creates a new GMimeFilterBest filter. flags are used to determine which information to keep statistics of. If the GMIME_FILTER_BEST_CHARSET bit is set, the filter will be able to compute the best charset for encoding the stream of data filtered. If the GMIME_FILTER_BEST_ENCODING bit is set, the filter will be able to compute the best Content-Transfer-Encoding for use with the stream being filtered.
Note: In order for the #g_mime_filter_best_charset() function to work, the stream being filtered MUST already be encoded in UTF-8.
flags : | filter flags |
Returns : | a new best filter with flags flags. |
const char* g_mime_filter_best_charset (GMimeFilterBest *best);
Calculates the best charset for encoding the stream filtered through the best filter.
best : | best filter |
Returns : | a pointer to a string containing the name of the charset best suited for the text filtered through best. |
GMimePartEncodingType g_mime_filter_best_encoding (GMimeFilterBest *best, GMimeBestEncoding required);
Calculates the best Content-Transfer-Encoding for the stream filtered through best that fits within the required encoding.
best : | best filter |
required : | encoding that all data must fit within |
Returns : | the best encoding for the stream filtered by best. |
