WebP.jl is a Julia library for handling [WebP](https://developers.google.com/speed/webp) images. WebP provides both lossy and lossless compression of images, and may offer smaller file sizes compared to JPEG and PNG.

The core functionality of this package is supported by the [libwebp](https://developers.google.com/speed/webp/docs/api) C library.

## Usage

This package provides functions for reading and writing WebP image files,

* `WebP.read_webp`

* `WebP.write_webp`

as well as functions for decoding and encoding WebP image data,

* `WebP.decode`

* `WebP.encode`

### Reading and writing

An image may be written,

```julia

using TestImages

using WebP

image = testimage("lighthouse")

WebP.write_webp("lighthouse.webp", image)

```

and subsequently read,

```julia

image = WebP.read_webp("lighthouse.webp")

```

### Decoding and encoding

An image may be encoded,

```julia

using TestImages

using WebP

image = testimage("lighthouse")

data = WebP.encode(image) # data is a Vector{UInt8}

```

and subsequently decoded,

```julia

image = WebP.decode(data)

```
