Methods

__init__(self, Bitmap, XY, Height, Width=None, Position = 'tl', InForeground = False)

Default class constructor.

Parameters:

• Bitmap (wx.Bitmap) – the bitmap to be drawn

• XY – the (x, y) coordinate of the corner of the scaled bitmap, or a 2-tuple, or a (2,) NumPy array

  a two character string indicating where in relation to the coordinates the bitmap should be oriented

  1st character	Meaning
  t	top
  c	center
  b	bottom

  2nd character	Meaning
  l	left
  c	center
  r	right

• InForeground (boolean) – should object be in foreground
