var fill = require("ndarray-fill")

var zeros = require("zeros")

var x = zeros([512, 512])

fill(x, function(a,b) {

  return a*a + b*b

})

imshow(colorize(x))

```

# Install

```

npm install apply-colormap

```

# API

### `require("apply-colormap")(array[, options])`

Applies a colormap to an ndarray

* `array` is an ndarray

* `options` is an object containing a list of properties to apply to the array

    + `colormap` determines the colormap to use (default "jet").  Names are consistent with the [`colormap`](https://www.npmjs.org/package/colormap) package.

    + `min` determines the lowest color in the image 

    + `max` determines the highest color in the image

    + `outBuffer` is an optional buffer into which the output is written

**Returns** An ndarray representing the colorized image or volume
