rotate(image, angle, resize=False, center=None, order=None, mode='constant', cval=0, clip=True, preserve_range=False)
Modes 'reflect' and 'symmetric' are similar, but differ in whether the edge pixels are duplicated during the reflection. As an example, if an array has values [0, 1, 2] and was padded to the right by four values using symmetric, the result would be [0, 1, 2, 2, 1, 0, 0], while for reflect it would be [0, 1, 2, 1, 0, 1, 2].
The order of the spline interpolation, default is 0 if image.dtype is bool and 1 otherwise. The order has to be in the range 0-5. See skimage.transform.warp
for detail.
Points outside the boundaries of the input are filled according to the given mode. Modes match the behaviour of numpy.pad
.
Used in conjunction with mode 'constant', the value outside the image boundaries.
Whether to clip the output to the range of values of the input image. This is enabled by default, since higher order interpolation may produce values outside the given input range.
Whether to keep the original range of values. Otherwise, the input image is converted according to the conventions of img_as_float
. Also see https://scikit-image.org/docs/dev/user_guide/data_types.html
Input image.
Rotation angle in degrees in counter-clockwise direction.
Determine whether the shape of the output image will be automatically calculated, so the complete rotated image exactly fits. Default is False.
The rotation center. If center=None
, the image is rotated around its center, i.e. center=(cols / 2 - 0.5, rows / 2 - 0.5)
. Please note that this parameter is (cols, rows), contrary to normal skimage ordering.
Rotated version of the input.
Rotate image by a certain angle around its center.

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
