## How to use?

OpenJpegDotNet provides **OpenJpeg APIs** and **Auxiliary APIs**. Auxiliary APIs allows developers to decode/encode jpeg 2000 data easily.

### :warning: Warning

Auxiliary APIs only wraps native OpenJpeg APIs. 

Auxiliary APIs may be changed in the future.

### Read

````csharp

byte[] image = System.IO.File.ReadAllBytes("test.j2k");

using OpenJpegDotNet.IO.Reader reader = new OpenJpegDotNet.IO.Reader(image);

bool result = reader.ReadHeader();

System.Drawing.Bitmap bitmap = reader.ReadData();
