One is "Alpha Channel" and the another one is "Mask". I have few questions regarding these two. As per the language reference, Quote:A Picture that is created with the constructor that omits the Depth parameter has an alpha channel. You will need to enable GDI+ on Windows for this to work. Otherwise you will get an PlatformNotSupportedException raised. I also get PlatformNotSupportedException in Mac for carbon build. One question, Why only a picture that is created with the constructor that omits the Depth parameter has an alpha channel? not a picture which created with depth value? What is the depth value actually indicate? For a picture that has a depth value, we can have a mask to control the transparency. we can't use alpha channel for that. So, I just can't relate these three thing. Someone can please help to understand the concept?
