PyQt4 and PySide

Qt 4 reached end-of-life on 2015-12-19. Its Python bindings are also EOL: PyQt4 since 2018-08-31 and PySide since 2015-10-14.

Support for PyQt4 and PySide has been removed from ImageQt. Please upgrade to PyQt5 or PySide2.

Setting the size of TIFF images

Setting the size of a TIFF image directly (eg. im.size = (256, 256)) throws an error. Use Image.resize instead.

API Additions

Custom unidentified image error

Pillow will now throw a custom UnidentifiedImageError when an image cannot be identified. For backwards compatibility, this will inherit from IOError.

Other Changes

Image.__del__

Implicitly closing the image’s underlying file in Image.__del__ has been removed. Use a context manager or call Image.close() instead to close the file in a deterministic way.

Previous method:

im = Image.open("hopper.png")
im.save("out.jpg")

Use instead:

with Image.open("hopper.png") as im:
    im.save("out.jpg")
