Transform image

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
