This operation will destroy the image core and release its memory.

The image data will be unusable afterward.

This function is required to close images that have multiple frames or

have not had their file read and closed by the

:py:meth:`~PIL.Image.Image.load` method. See :ref:`file-handling` for

more information.

Base class for stub image loaders.

certain format, but relies on external code to load the file.

|
Reads large blocks in a safe way. Unlike fp.read(n), this function
|
doesn't trust the user. If the requested size is larger than
|
SAFEBLOCK, the file is read block by block.
|
|
:param fp: File handle. Must implement a <b>read</b> method.
|
:param size: Number of bytes to read.
|
:returns: A string containing <i>size</i> bytes of data.
|
|
Raises an OSError if the file is truncated and the read cannot be completed
