# jxlatte

Work-in-progress pure java JPEG XL decoder

## Compiling

JXLatte is built with the [Meson build system](https://mesonbuild.com/).

To build, create a build directory, for example, with `mkdir build && cd build`.

Then run `meson setup ../` to set up the build directory, and `ninja` to compile JXLatte.

## Running

JXLatte can be executed just like any normal jar file:

```sh

java -jar jxlatte.jar samples/art.jxl output.png

```

The JAR can also be used as a library. To use it, add it to your application's classpath.

```java

InputStream input = someInputStream;

OutputStream output = someOutputStream;

JXLDecoder decoder = new JXLDecoder(input);

JXLImage image = decoder.decode();

PNGWriter writer = new PNGWriter(image);

writer.write(output);

```
