# Miscellaneous routines (`scipy.misc`)

Various utilities that don’t have another home.

Note that Pillow (https://python-pillow.org/) is not a dependency of SciPy, but the image manipulation functions indicated in the list below are not available without it.

`ascent`() | Get an 8-bit grayscale bit-depth, 512 x 512 derived image for easy use in demos
`bytescale`(data[, cmin, cmax, high, low]) | Byte scales an array (image).
`central_diff_weights`(Np[, ndiv]) | Return weights for an Np-point central derivative.
`comb`(N, k[, exact, repetition]) | The number of combinations of N things taken k at a time.
`derivative`(func, x0[, dx, n, args, order]) | Find the n-th derivative of a function at a point.
`face`([gray]) | Get a 1024 x 768, color image of a raccoon face.
`factorial`(n[, exact]) | The factorial of a number or array of numbers.
`factorial2`(n[, exact]) | Double factorial.
`factorialk`(n, k[, exact]) | Multifactorial of n of order k, n(!!...!).
`fromimage`(im[, flatten, mode]) | Return a copy of a PIL image as a numpy array.
`imfilter`(arr, ftype) | Simple filtering of an image.
`imread`(name[, flatten, mode]) | Read an image from a file as an array.
`imresize`(arr, size[, interp, mode]) | Resize an image.
`imrotate`(arr, angle[, interp]) | Rotate an image counter-clockwise by angle degrees.
`imsave`(name, arr[, format]) | Save an array as an image.
`imshow`(arr) | Simple showing of an image through an external viewer.
`info`([object, maxwidth, output, toplevel]) | Get help information for a function, class, or module.
`lena`() | Function that previously returned an example image
`logsumexp`(a[, axis, b, keepdims, return_sign]) | Compute the log of the sum of exponentials of input elements.
`pade`(an, m) | Return Pade approximation to a polynomial as the ratio of two polynomials.
`toimage`(arr[, high, low, cmin, cmax, pal, ...]) | Takes a numpy array and returns a PIL image.
`source`(object[, output]) | Print or write to a file the source code for a NumPy object.
`who`([vardict]) | Print the NumPy arrays in the given dictionary.
