A library for image manipulation with power of renderScript

Pixl

Pixl is a library for image manipulation with power of renderScript which is faster than other ordinary solutions, currently it includes three basic scripts, brightness, contrast, saturation.

Installation

Add Jitpack to your project build.gradle file

  allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
		jcenter()
	}
}

}

Then add this dependency to your app build.gradle file.

  dependencies {
        implementation 'com.jibraniqbal.pixl:pixl:0.0.1'
}

Usage

You can see the example with brightness, contrast, saturation with seekbar, given the value 0-100%

Add support for API-19 add this to you build.gradle

android {
	defaultConfig {
		...
		renderscriptTargetApi 19
    		renderscriptSupportModeEnabled true
	}
}

Intialization

  val pixl = Pixl(context)

Brightness

  brightnessSeek.setOnSeekBarChangeListener(object : SeekBar.OnSeekBarChangeListener {
        override fun onProgressChanged(p0: SeekBar?, p1: Int, p2: Boolean) {
            val input = originalBrightnessImage
            val output = Bitmap.createBitmap(input.width, input.height, input.config)
            pixl.setBrightness(input, output, p0?.progress?.toFloat() ?: 0f)
            postImage(brightnessImage, output)
        }
        override fun onStartTrackingTouch(p0: SeekBar?) {}
        override fun onStopTrackingTouch(p0: SeekBar?) {}
    })

Contrast

contrastSeek.setOnSeekBarChangeListener(object : SeekBar.OnSeekBarChangeListener {
        override fun onProgressChanged(p0: SeekBar?, p1: Int, p2: Boolean) {
            val input = originalContrastImage
            val output = Bitmap.createBitmap(input.width, input.height, input.config)
            pixl.setContrast(input, output, p0?.progress?.toFloat() ?: 0f)
            postImage(contrastImage, output)
        }
        override fun onStartTrackingTouch(p0: SeekBar?) {}
        override fun onStopTrackingTouch(p0: SeekBar?) {}
    })

Saturation

 saturationSeek.setOnSeekBarChangeListener(object : SeekBar.OnSeekBarChangeListener {
        override fun onProgressChanged(p0: SeekBar?, p1: Int, p2: Boolean) {
            val input = originalSaturationImage
            val output = Bitmap.createBitmap(input.width, input.height, input.config)
            pixl.setSaturation(input, output, p0?.progress?.toFloat() ?: 0f)
            postImage(saturationImage, output)
        }
        override fun onStartTrackingTouch(p0: SeekBar?) {}
        override fun onStopTrackingTouch(p0: SeekBar?) {}
    })
