# dxt

DXT decompression library written in Go. It supports DXT1, DXT3 and DXT5 decompression to RGBA

# Installation

```

go get -u github.com/mauserzjeh/dxt

```

# Tests

```

go test -v

```

# Usage

```go

// import the library

import "github.com/mauserzjeh/dxt"

var dxtBytes []byte

var width uint

var height uint

// ...read the DXT encoded data...

// ...and also obtain the width and height of the image...

// decompress DXT1 to RGBA

rgbaBytes, err := dxt.DecodeDXT1(dxtBytes, width, height)

// or

// decompress DXT3 to RGBA

rgbaBytes, err := dxt.DecodeDXT3(dxtBytes, width, height)

// or

// decompress DXT5 to RGBA

rgbaBytes, err := dxt.DecodeDXT5(dxtBytes, width, height)

// check for errors

if err != nil {

    log.Fatal(err)

}

// rgbaBytes should hold the decompressed RGBA data if no error happened

//             R    G   B    A    R   G    B  ...

// ie. []byte{123, 23, 234, 212, 21, 128, 52, ...}

```
