|
-----
|
|
|
|
This release fixes regressions in 5.4.0.
|
|
|
|
Installation on Termux
|
|
^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
A change to the way Pillow detects libraries during installed prevented
|
|
installation on Termux, which does not have ``/sbin/ldconfig``. This is now
|
|
fixed.
|
|
|
|
PNG: Handle IDAT chunks after image end
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Some PNG images have multiple IDAT chunks. In some cases, Pillow will stop
|
|
reading image data before the IDAT chunks finish. A regression caused an
|
|
:py:exc:`EOFError` exception when previously there was none. This is now fixed, and
|
|
file reading continues in case there are subsequent text chunks.
|
|
|
|
PNG: MIME type
|
|
^^^^^^^^^^^^^^
|
|
|
|
The addition of limited APNG support to the PNG plugin also overwrote the MIME
|
|
type for PNG files, causing "image/apng" to be returned as the MIME type of
|
|
both APNG and PNG files. This has been fixed so the MIME type of PNG files is
|
|
"image/png".
|
|
|
|
File closing
|
|
^^^^^^^^^^^^
|
|
|
|
A regression caused an unsupported image file to report a
|
|
``ValueError: seek of closed file`` exception instead of an :py:exc:`OSError`. This
|
|
has been fixed by ensuring that image plugins only close their internal ``__fp``
|
|
if they are not the same as ``ImageFile``'s ``fp``, allowing each to manage their own
|
|
file pointers.
