This constant refers to the transparent color in a picture or push button bitmap. For example, assume you have a push button that contains a bitmap that is blue, red, and green. If you set COLOR_IndexTransparent to COLOR_Blue, the blue portions of the bitmap become transparent; this allows the color of the form window underneath the push button to show through. Use this constant with the SalColorGet and SalColorSet functions. Value = 101
