+"A platform-independent image class.  An image can be created from
+data, or using `wx.Bitmap.ConvertToImage`, or loaded from a file in a
+variety of formats.  Functions are available to set and get image
+bits, so it can be used for basic image manipulation.
+
+A wx.Image cannot be drawn directly to a `wx.DC`.  Instead, a
+platform-specific `wx.Bitmap` object must be created from it using the
+`wx.BitmapFromImage` constructor. This bitmap can then be drawn in a
+device context, using `wx.DC.DrawBitmap`.
+
+One colour value of the image may be used as a mask colour which will
+lead to the automatic creation of a `wx.Mask` object associated to the
+bitmap object.
+
+wx.Image supports alpha channel data, that is in addition to a byte
+for the red, green and blue colour components for each pixel it also
+stores a byte representing the pixel opacity. An alpha value of 0
+corresponds to a transparent pixel (null opacity) while a value of 255
+means that the pixel is 100% opaque.
+
+Unlike RGB data, not all images have an alpha channel and before using
