The PIL.ImageTransform Module


AffineTransform (class)  [ #PIL.ImageTransform.AffineTransform-class# ]

Define an affine image transform.


matrix

A 6-tuple (
a, b, c, d, e, f) containing
   the first two rows from an affine transform matrix.


For more information about this class, see #PIL.ImageTransform.AffineTransform-classThe AffineTransform Class .


ExtentTransform (class)  [ #PIL.ImageTransform.ExtentTransform-class# ]

Define a transform to extract a subregion from an image.


bbox

A 4-tuple (
x0, y0, x1, y1) which specifies
   two points in the input image's coordinate system.


For more information about this class, see #PIL.ImageTransform.ExtentTransform-classThe ExtentTransform Class .


MeshTransform (class)  [ #PIL.ImageTransform.MeshTransform-class# ]

Define an mesh image transform.


data

A list of (bbox, quad) tuples.


For more information about this class, see #PIL.ImageTransform.MeshTransform-classThe MeshTransform Class .


QuadTransform (class)  [ #PIL.ImageTransform.QuadTransform-class# ]

Define an quad image transform.


xy

An 8-tuple (
x0, y0, x1, y1, x2, y2, y3, y3) which
  contain the upper left, lower left, lower right, and upper right
  corner of the source quadrilateral.


For more information about this class, see #PIL.ImageTransform.QuadTransform-classThe QuadTransform Class .



The AffineTransform Class 


AffineTransform (class)  [ #PIL.ImageTransform.AffineTransform-class# ]

Define an affine image transform.

This function takes a 6-tuple (
a, b, c, d, e, f) which
contain the first two rows from an affine transform matrix. For
each pixel (
x, y) in the output image, the new value is
taken from a position (a 
x + b y + c,
d 
x + e y + f) in the input image, rounded to
nearest pixel.

This function can be used to scale, translate, rotate, and shear the
original image.


matrix

A 6-tuple (
a, b, c, d, e, f) containing
   the first two rows from an affine transform matrix.




The ExtentTransform Class 


ExtentTransform (class)  [ #PIL.ImageTransform.ExtentTransform-class# ]

Define a transform to extract a subregion from an image.

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 (
x0, y0)
in the input image will end up at (0,0) in the output image,
and (
x1, y1) at size.

This method can be used to crop, stretch, shrink, or mirror an
arbitrary rectangle in the current image. It is slightly slower than
crop, but about as fast as a corresponding resize
operation.


bbox

A 4-tuple (
x0, y0, x1, y1) which specifies
   two points in the input image's coordinate system.




The MeshTransform Class 


MeshTransform (class)  [ #PIL.ImageTransform.MeshTransform-class# ]

Define an mesh image transform.  A mesh transform consists of one
or more individual quad transforms.


data

A list of (bbox, quad) tuples.




The QuadTransform Class 


QuadTransform (class)  [ #PIL.ImageTransform.QuadTransform-class# ]

Define an quad image transform.

Maps a quadrilateral (a region defined by four corners) from the
image to a rectangle of the given size.


xy

An 8-tuple (
x0, y0, x1, y1, x2, y2, y3, y3) which
  contain the upper left, lower left, lower right, and upper right
  corner of the source quadrilateral.
