Package rez provides image resizing in pure Go and SIMD.

Featuring:

```

- YCbCr, RGBA, NRGBA & Gray resizes

- YCbCr Chroma subsample ratio conversions

- Optional interlaced-aware resizes

- Parallel resizes

- SIMD optimisations on AMD64

```

The easiest way to use it is:

```

err := Convert(output, input, NewBicubicFilter())

```

However, if you plan to convert video, where resize parameters are the same for

multiple images, the best way is:

```

cfg, err := PrepareConversion(output, input)

converter, err := NewConverter(cfg, NewBicubicFilter())

for i := 0; i < N; i++ {

    err := converter.Convert(output[i], input[i])

}

```

Note that by default, images are resized in parallel with GOMAXPROCS slices.

Best performance is obtained when GOMAXPROCS is at least equal to your CPU

count.
