Because the JPEG format lacks an alpha transparency channel, transparent PNG pixels must be matted against a solid color.
Softnag creates a canvas element, paints the selected background matte color (defaulting to clean white), and composite-renders the PNG image on top.
The composite buffer is then encoded into standard JPEG format using your chosen compression quality factor.
