# Download

```groovy
implementation 'io.mhssn:colorpicker:1.0.0'
```
# Usage

```kotlin
ColorPicker {
    color = it
}
```

You can provide a type for the color picker as the following.

```kotlin
ColorPicker(
    type = ColorPickerType.Classic()
) {
    color = it
}
```
#### Color picker types
- Classic
  
  ```kotlin
  ColorPickerType.Classic(
      showAlphaBar = true
  )
  ```
  
- Circle

```kotlin
  ColorPickerType.Circle(
      showBrightnessBar = true,
      showAlphaBar = true,
      lightCenter = true
  )
  ```

- Ring

```kotlin
  ColorPickerType.Ring(
      ringWidth = 10.dp,
      previewRadius = 80.dp,
      showLightColorBar = true,
      showDarkColorBar = true,
      showAlphaBar = true,
      showColorPreview = true
  )
  ```

- Simple Ring

```kotlin
  ColorPickerType.SimpleRing(
      colorWidth = 20.dp,
      tracksCount = 5,
      sectorsCount = 24
  )
  ```

## Color Picker Dialog

```kotlin
ColorPickerDialog(
    show = showDialog,
    type = colorPickerType,
    properties = DialogProperties(),
    onDismissRequest = {
    	showDialog = false
    },
    onPickedColor = {
    	color = it
    },
)
```

## Useful Extensions

- ```kotlin
  val color = Color(0xffe1a1c1)
  val alpha = color.alpha() //return alpha value as integer => 255
  val red = color.red() //return red value as integer => 225
  val green = color.green() //return green value as integer => 161
  val blue = color.blue() //return blue value as integer => 193
  val hex = color.toHex() //return argb color as hex string
  val (alpha, red, green, blue) = color.argb() //return an array for all color channels value
  ```

- add `Modifier.transparentBackground` to draw behind your composable element a transparent effect background

```kotlin
  Box(
      modifier = Modifier
      .width(205.dp)
      .height(300.dp)
      .clip(RoundedCornerShape(32.dp))
      .transparentBackground(verticalBoxesCount = 16)
      .background(Color.Cyan.copy(alpha = 0.2f))
  )
  ```
