You can use set ascept ratio method on GPUImageView
gpuImageView.setRatio(getDecimalEquivalent(bitmap.width,bitmap.height))
gpuImageView.setImage(bitmap)

private fun getDecimalEquivalent(width: Int, height: Int): Float {
val factor = greatestCommonFactor(width, height)
val widthRatio: Float = width / factor
val heightRatio: Float = height / factor
return widthRatio / heightRatio
}

private fun greatestCommonFactor(width: Int, height: Int): Float {
    return if (height == 0) width.toFloat() else greatestCommonFactor(height, width % height)
}
