Transforms and image into another shape

Documentation

Algorithms

crop

Crops the image to the given rectanglular area

x

Left edge of image

y

Top edge of image

width

Width of image

height

Height of image

padding

Adds a padding to an image

x

If positive, amount of padding added on the left side. If negative the amount of padding added on the right side.

y

If positive, amount of padding added on the top.If negative the amount of padding added on the bottom.

k

Constant value used in padded areas

add alpha

Adds an alpha with value 1.0 inside image, 0.0 outside

rescale

Rescales an image by a given factor

interpolation degree

Degree of polynomial (0 - 5) used for interpolation. 0 - no interpolation, 1 - bi-linear interpolation, 3 - bi-cubic interpolation

scale x

Scale factor along X direction (horizontal)

scale y

Scale factor along Y direction (vertical)

resize

Resizes an image to match the given dimensions

width

The new width of the image

height

The new height of the image

padding

Adds padding to fill out full width/height after aspect-correct scaling

aspect

Preserve aspect ratio (gives smaller size on one axis)

interpolation degree

Degree of polynomial (0 - 5) used for interpolation. 0 - no interpolation, 1 - bi-linear interpolation, 3 - bi-cubic interpolation

More info: http://scikit-image.org/docs/0.13.x/api/skimage.transform.html#skimage.transform.resize

rotate

Rotates an image

angle

Angular degrees to rotate counterclockwise

resize

If true new image dimensions are calculated to exactly fit the image
