 - PNG images with an alpha channel can be saved using this function. To do this, create
 8-bit (or 16-bit) 4-channel image BGRA, where the alpha channel goes last. Fully transparent pixels
 should have alpha set to 0, fully opaque pixels should have alpha set to 255/65535 (see the code sample below).
