# Unitils
Library containing multiple Unity utilities function and workflows.
## Steganography
This utility namespace implements a simple [steganography](https://en.wikipedia.org/wiki/Steganography) algorithm allowing a user to "hide" data inside a Unity `Texture2D`. Basically it uses the least significant bits of the color channels to hier data.
A quick example can be found in `SteganoCtrl.cs` (used in the `Steganography` scene):
```csharp
void Start () {
sr = gameObject.GetComponent();
// Encode secretMsg in a texture. This returns a copy of the texture
encodedTex = Steganography.Encode(sr.sprite.texture, secretMsg);
// Set the new texture in our Sprite component
sr.sprite = Sprite.Create(encodedTex, new Rect(0.0f, 0.0f, encodedTex.width, encodedTex.height), new Vector2(0.5f, 0.5f));
}
private void OnGUI()
{
GUILayout.BeginHorizontal();
isDecoded = GUILayout.Toggle(isDecoded, "Decode");
if (isDecoded)
{
// Decode the secretMsg from the texture
var decodedMsg = Steganography.DecodeAsString(sr.sprite.texture);
GUILayout.Label(decodedMsg);
}
else
{
GUILayout.Label("**********************");
}
GUILayout.Button(encodedTex);
GUILayout.EndHorizontal();
}
```
### More details
We support multiple ways to encode data depending on how you want to store the data and affect image quality:
```csharp
public enum Format
{
RGB1,
RGB2,
RGBA1,
RGBA2,
A1,
A2
}
```
Each stream of data has a 8 bytes header that contains the format the data is written with and the size of the written data.
