| * Note that the viewer shows transparency, not opacity, and it shows it in percentage. To convert from viewer transparency to an alpha value suitable for use with this function, use this formula: alpha=(100-transparency)/100. For example, a transparency of 35% is an alpha value of 0.65. | * Note that the viewer shows transparency, not opacity, and it shows it in percentage.
