ndarray-resample
================
Resamples an ndarray by an arbitrary (rational) factor using a sinc kernel.

[![build status](https://secure.travis-ci.org/scijs/ndarray-resample.png)](http://travis-ci.org/scijs/ndarray-resample)

## Example
Here is a simple example showing how to downsample an image:

```javascript
var baboon = require("luminance")(require("baboon-image"))
var x = require("zeros")([256,256])
require("ndarray-resample")(x, baboon)
require("save-pixels")(x, "png").pipe(process.stdout)
```

#### Output
![Output](example/baboon2.png)

##Install
Install using [npm](https://www.npmjs.com/):

    npm install ndarray-resample

## API
#### `require("ndarray-resample")(output, input[, clamp_lo, clamp_hi])`
Resamples input by a factor of `output.shape/input.shape`, storing the result in output (this also means the factor can differ per dimension).

* `output` gets the result of resampling
* `input` is the array that gets resampled
* `clamp_lo` is a threshold placed on the pixels
* `clamp_hi` is an upper threhsold placed on the pixels

**Note** that the pixel at the "origin" in the output corresponds to the pixel at the origin in the input. Also, the boundary conditions are periodic (for now).

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.
