+\wxheading{Alpha channel support}
+
+Starting from wxWidgets 2.5.0 wxImage 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
+\helpref{GetAlpha}{wximagegetalpha} you should check if this image contains
+an alpha channel with \helpref{HasAlpha}{wximagehasalpha}. Note that currently
+only the PNG format has full alpha channel support so only the images loaded
+from PNG files can have alpha and, if you initialize the image alpha channel
+yourself using \helpref{SetAlpha}{wximagesetalpha}, you should save it in PNG
+format to avoid losing it.
