👀 Usage

Basic Example

val cloud = Cloudy.with(this) // context
    // source view (any view) isPreBlur If you specify true, it starts immediately.
    .from(imageView, isPreBlur = true) 
    // recommend argb (@ColorInt)
    .color(Color.parseColor("#50ffffff")) 
    // set radius
    .radius(200f)
    // target view (any view)
    .into(textView) 

Lazy start blur

cloud.blur() // start blur

Lazy change Color

cloud.color(Color.CYAN) // @ColorInt

Lazy change Radius

cloud.radius(25f) // range is 0f .. 200f

Scroll Changed Listener

// vertical
verticalScrollView.setOnScrollChangeListener { _, _, scrollY, _, _ ->
    cloud.onVerticalScroll(scrollY)                                      
}
// horizontal 
horizontalScrollView.setOnScrollChangeListener { _, scrollX, _, _, _ ->
    cloud.onHorizontalScroll(scrollX)                                      
}

Clear

// target view background = null
cloud.clear()

Get blurred bitmap

cloud.get() // nullable bitmap
