Setting region to calculate palette from a specified area doesn't work

[amitkma]

When we specify a region using the setRegion method of palette builder, the region internally is always set as a full bitmap.

I think the issue is this code

public fun setRegion(left: Int, top: Int, right: Int, bottom: Int): Builder {
            val bitmap = imageBitmap
            if (bitmap != null) {
                if (region == null) {
                    region = Rect(0f, 0f, bitmap.width.toFloat(), bitmap.height.toFloat())
                }

                // Now just get the intersection with the region
                val other = Rect(left.toFloat(), top.toFloat(), right.toFloat(), bottom.toFloat())
                if (!region!!.overlaps(other)) {
                    throw IllegalArgumentException("The given region must intersect with "
                        + "the Bitmap's dimensions.")
                }
            }
            return this
        }

When we set a region, it should be initialised as region = Rect(left, top, right, bottom)

Let me know if I am incorrect or if there is a way to fix it.

Any ideas?
