## Install
**Step 1.** Add it in your root build.gradle at the end of repositories:

``` gradle
allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}
````
**Step 2.** Add the dependency

``` gradle
dependencies {
    implementation 'com.github.SirLYC:ImageLabelView:{latest version}'
}
```
## Use
> You can check [sample code](https://github.com/SirLYC/ImageLabelView/tree/master/sample) here

**Step1.** Add to your layout

**Step2.** Set a LabelCreator
The labelCreator is used when you draw a new label. It can create a new label via its createLabel() method.
First, you need to implement a 
```
ImageLabelView#LabelCreator. 
```
There is a simple implementation in sample code for rect label:
```kotlin
label.labelCreator = object : ImageLabelView.LabelCreator {
            override fun createLabel(): RectLabel {
                return RectLabel()
            }
        }
```
**Remember to set it to set it to ImageLabelView's labelCreator.**
> You can create any type of Label which may return different kinds of data.

**Step3.** Set an image to the view

Set a bitmap to the ImageLabelView, and it will start to show this phone like a imageView with **center inside mode**. The bitmap can be null, which will let the view clear old labels...
```kotlin
val bitmap: Bitmap? = ... // download or read from disk
label.setBitmap(bitmap)
```

**Step4.** Do your job in different mode

When a nonnull bitmap is present, there are 4 modes to operate a image.
- PREVIEW<br>
This is default mode. Everytime a new bitmap is set to this view, the mode will change to it.
In this mode, you can move or scale the image to the perfect position and size for labelling.
- DRAW<br>
In this mode, you can draw a new label. Take rectangle for example. When your finger touch the screen and move, there will be a rectangle right on the image whose left and top is your start posintion and right and bottom is your end position.
After your finger up, the view will immediately change to SELECT mode.
- UPDATE<br>
In this mode, you can resize or change label's position. Take rectangle for example, you can drag a regtangle' vertext or a egde to resize it, or move the whole of the rectange (when your finger down right in the rectangle).
- SELECT<br>
When click or long press, a rectangle at your finger's position will be selected (if drawing end, the new-created label will be selected automatically.). When a label is selected, you can get it by
``` kotlin
label.selectingLabel()
```
At this time, you may let user to input or do other things to change the message of the label or just delete it.

**Step5.** Export your data
Just get the label and call it's **getData()** or get its **message property**!

## Todo/Fix
- [x] fix multi-selection problem when tap once
- [ ] fix state loss after config changes (such as screen orientation, languages...)
- [ ] circle label
- [ ] triangle label
- [ ] other polygon label...
