============

Mip map generator for tiled texture atlases.

## Example

```javascript

var fs = require("fs")

var ndarray = require("ndarray")

var savePixels = require("save-pixels")

require("get-pixels")("./painterly.png", function(err, image) {

  //Cut 256x256x4 array into 16x16 tiles of width 16x16x4

  var tilemap = ndarray(image.data,

    [16, 16, 16, 16, 4],

    [16*16*16*4, 16*4, 16*16*4, 4, 1],

    0)

    

  //Compute mip pyramid

  var mipmap = require("tile-mip-map")(tilemap)

  //Save levels to images

  for(var i=0; i

## Install

    npm install tile-mip-map

    

### `require("tile-mip-map")(tilemap[, pad])`

Constructs a mip pyramid for the given tile map

* `tilemap` is a 5d array where the first two dimenions are the number of tiles, the next two are the width of each tile, and the last dimension is the number of channels.

* `pad` the number of times to pad each tile by.  default 1x

**Returns** A list of mip pyramids.
