# Download Library 

### Gradle:
For __androidWM__ supports the invisible digital watermarks (package size: 1Mb):

```gradle
implementation 'com.huangyz0918:androidwm:0.2.3'
```

For __androidWM-light__ only supports the visible watermarks (package size: 28Kb):

```gradle
implementation 'com.huangyz0918:androidwm-light:0.1.2'
```

# Quick Start
### Build a Watermark
After downloading the library and adding it into your project, You can create a `WatermarkImage` or `WatermarkText` and do some pre-settings with their instance.

```java
    WatermarkText watermarkText = new WatermarkText(inputText)
            .setPositionX(0.5)
            .setPositionY(0.5)
            .setTextColor(Color.WHITE)
            .setTextFont(R.font.champagne)
            .setTextShadow(0.1f, 5, 5, Color.BLUE)
            .setTextAlpha(150)
            .setRotation(30)
            .setTextSize(20);
```

There are many attributes that can help you to make a customization with a text watermark or an image watermark. You can get more information from the documentation section that follows.

After the preparation is complete, you need a `WatermarkBuilder` to create a watermark image. You can get an instance from the `create` method of `WatermarkBuilder`, and, you need to put a `Bitmap` or an int `Drawable` as the background image first.

```java
    WatermarkBuilder
            .create(context, backgroundBitmap)
            .loadWatermarkText(watermarkText) // use .loadWatermarkImage(watermarkImage) to load an image.
            .getWatermark()
            .setToImageView(imageView);
```

![](https://i.loli.net/2018/09/01/5b8aa948a2020.png)

### Select the Drawing Mode
You can select normal mode (default) or tile mode in `WatermarkBuilder.setTileMode()`:

```java
    WatermarkBuilder
            .create(this, backgroundBitmap)
            .loadWatermarkText(watermarkText)
            .setTileMode(true) // select different drawing mode.
            .getWatermark()
            .setToImageView(backgroundView);
```

Boom! the watermark has been drawed now:

### Get the Output
You can create both text watermark and image watermark, and load them into your `WatermarkBuilder`. If you want to get the result bitmap, we also have a `.getOutputImage()` method for you after getting the watermark:

```java
    Bitmap bitmap = WatermarkBuilder
            .create(this, backgroundBitmap)
            .getWatermark()
            .getOutputImage();
```

### Build Multiple Watermarks
And if you want to add many watermarks at the same time, you can use a `List<>` to hold your watermarks. You can add the `List<>` into the background image by ` .loadWatermarkTexts(watermarkTexts)`, the same as watermark images:

```java
    WatermarkBuilder
            .create(this, backgroundBitmap)
            .loadWatermarkTexts(watermarkTexts)
            .loadWatermarkImages(watermarkImages)
            .getWatermark();
```

### Ways of Loading Resources
If you want to load a watermark image or a watermark text from a view or resources, you can use those methods:

```java
WatermarkText watermarkText = new WatermarkText(editText); // for a text from EditText.
WatermarkText watermarkText = new WatermarkText(textView); // for a text from TextView.
WatermarkImage watermarkImage = new WatermarkImage(imageView); // for an image from ImageView.
WatermarkImage watermarkImage = new WatermarkImage(this, R.drawable.image); // for an image from Resource.
```

The background loaded in `WatermarkBuilder` can be created from resources or `ImageView` too: 

```java
    WatermarkBuilder
            .create(this, backgroundImageView) // .create(this, R.drawable.background)
            .getWatermark()
```

If you didn't load a watermark ,the default value is as the same as background, nothing will be changed.

### Invisible Watermarks (beta)

In this library, we also support the invisible watermark and the detection of them. We can use two ways to build an invisible watermark: the LSB (spatial domain) and the wavelet transform (Frequency domain). All you need to do is to use a boolean (isLSB) to distinguish them. __(PS. the watermark in frequency domain is under developing)__

You can create a new invisible watermark by the `WatermarkBuilder`'s `.setInvisibleWMListener`:

```java
     WatermarkBuilder
            .create(this, backgroundBitmap)
            .loadWatermarkImage(watermarkBitmap)
            .setInvisibleWMListener(true, new BuildFinishListener<Bitmap>() {
                @Override
                public void onSuccess(Bitmap object) {
                    if (object != null) {
                       // do something...
                    }
                }

                @Override
                public void onFailure(String message) {
                      // do something...
                }
            });
```
The first paramter of `setInvisibleWMListener` is `isLSB`, if false, the invisible algorithm will change to the frequency domain. 

To detect the invisible watermark, you can use `WatermarkDetector`, you need to put a boolean parameter in `.create` method, since we have two kinds of invisible watermarks, if `isLSB` is true, the detector can detect LSB watermarks, if not, the detector can detect the watermarks in the frequency domain.

```java
     WatermarkDetector
            .create(inputBitmap, true)
            .detect(false, new DetectFinishListener() {
                @Override
                public void onSuccess(DetectionReturnValue returnValue) {
                       Bitmap watermarkImage = returnValue.getWatermarkBitmap();
                       String watermarkString = returnValue.getWatermarkString();
                 }

                @Override
                public void onFailure(String message) {
                       // do something...
                }
            });
```
