__init__()¶

static get_global_ptr()¶: Returns a pointer to the global PNMFileTypeRegistry object.

get_num_types()¶: Returns the total number of types registered.

get_type()¶: Returns the nth type registered.

get_type_by_handle()¶: Returns the PNMFileType instance stored in the registry for the given TypeHandle, e.g. as retrieved by a previous call to get_type() on the type instance.

get_type_from_extension()¶: Tries to determine what the PNMFileType is likely to be for a particular image file based on its extension. Returns a suitable PNMFileType pointer, or NULL if no type can be determined.

get_type_from_magic_number()¶: Tries to determine what the PNMFileType is likely to be for a particular image file based on its magic number, the first two bytes read from the file. Returns a suitable PNMFileType pointer, or NULL if no type can be determined.

get_types() → list¶

property types → Sequence[PNMFileType]¶: Returns the nth type registered.

write()¶: Writes a list of supported image file types to the indicated output stream, one per line.
