Top-level functions summary

Bitmap	createBitmap(width: Int, height: Int, config: Config = Bitmap.Config.ARGB_8888) Returns a mutable bitmap with the specified width and height.
Bitmap	createBitmap(width: Int, height: Int, config: Config = Bitmap.Config.ARGB_8888, hasAlpha: Boolean = true, colorSpace: ColorSpace = ColorSpace.get(ColorSpace.Named.SRGB)) Returns a mutable bitmap with the specified width and height.
Matrix	rotationMatrix(degrees: Float, px: Float = 0.0f, py: Float = 0.0f) Creates a rotation matrix, defined by a rotation angle in degrees around the pivot point located at the coordinates (px, py).
Matrix	scaleMatrix(sx: Float = 1.0f, sy: Float = 1.0f) Creates a scale matrix with the scale factor sx and sy respectively on the x and y axis.

Extension functions summary

For android.graphics.Bitmap
Bitmap	Bitmap.applyCanvas(block: Canvas.() -> Unit) Creates a new Canvas to draw on this bitmap and executes the specified block on the newly created canvas.
operator Boolean	Bitmap.contains(p: Point) Returns true if the specified point is inside the bitmap.
operator Boolean	Bitmap.contains(p: PointF) Returns true if the specified point is inside the bitmap.
operator Int	Bitmap.get(x: Int, y: Int) Returns the value of the pixel at the specified location.
Bitmap	Bitmap.scale(width: Int, height: Int, filter: Boolean = true) Creates a new bitmap, scaled from this bitmap, when possible.
operator Unit	Bitmap.set(x: Int, y: Int, @ColorInt color: Int) Writes the specified color int into the bitmap (assuming it is mutable) at the specified (x, y) coordinate.
