A drawing view for your android application							



### Download

For information : checkout [Sample App Code](https://github.com/divyanshub024/AndroidDraw/tree/master/app) in repository.



## Dependency

*Step 1*. Add the JitPack repository to your build file

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.divyanshub024:AndroidDraw:v0.1'

	}

  

  ```

## Usage

There are two ways to use this library.

### 1. Use Activity

You can call the `Drawing Activity` using `startActivityForResult` which will return you bitmap in byteArray. By using this method you will have all the features like change strokeWidth, change strokeColor, change Alpha, erase, redo, undo.

```kotlin

val intent = Intent(this, DrawingActivity::class.java)

startActivityForResult(intent, REQUEST_CODE_DRAW)

// Get bitmap in onActivityResult

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {

        if (data != null && resultCode == Activity.RESULT_OK) {

            when(requestCode){

                REQUEST_CODE_DRAW -> {

                    val result= data.getByteArrayExtra("bitmap")

                    val bitmap = BitmapFactory.decodeByteArray(result, 0, result.size)

                    saveImage(bitmap)

                }

            }

        }

    }

```

### 2.Use DrawView

#### Declaration

```xml

```

- To clear canvas

```

draw_view.clearCanvas()

```

- To set stroke width

```kotlin

// takes input as Float

draw_view.setStrokeWidth(strokeWidth)

```

- To set stroke alpha

```kotlin

// takes input as Int

draw_view.setAlpha(progress)

```

- To set stroke color

```

draw_view.setColor(color)

```

- To undo

```

draw_view.undo()

```

- To redo

```

draw_view.redo()

```
