<dt><b>AffineTransform</b> (class)  [<a href='#PIL.ImageTransform.AffineTransform-class'>#</a>]</dt>
<dd>
<p>Define an affine image transform.
</p><p>
This function takes a 6-tuple (<i>a, b, c, d, e, f</i>) which
contain the first two rows from an affine transform matrix. For
each pixel (<i>x, y</i>) in the output image, the new value is
taken from a position (a <i>x</i> + b <i>y</i> + c,
d <i>x</i> + e <i>y</i> + f) in the input image, rounded to
nearest pixel.
</p><p>
This function can be used to scale, translate, rotate, and shear the
original image.

<dt><b>ExtentTransform</b> (class)  [<a href='#PIL.ImageTransform.ExtentTransform-class'>#</a>]</dt>
<dd>
<p>Define a transform to extract a subregion from an image.
</p><p>
Maps a rectangle (defined by two corners) from the image to a
rectangle of the given size.  The resulting image will contain
data sampled from between the corners, such that (<i>x0, y0</i>)
in the input image will end up at (0,0) in the output image,
and (<i>x1, y1</i>) at <i>size</i>.
</p><p>
This method can be used to crop, stretch, shrink, or mirror an
arbitrary rectangle in the current image. It is slightly slower than
<b>crop</b>, but about as fast as a corresponding <b>resize</b>
operation.
