Ok, Thanks a lot for that information - If we ignore Alpha channel, then how we can apply the transparency on converting ARGB to RGB. How we can make use of Alpha?
I have ARGB value which I need to convert to RGB and paint it on a Grid.
Can anyone provide a VC sample which illustrates ARGB to RGB conversion ?

Many Thanks,

Solution 1

AFAIK, you can't convert ARGB to RGB without ignoring the Alpha channel: it provides supplementary information (namely the transparency) to the color defined by the RGB component.

That is like trying to convert a painting into a canvas without removing any paint...

You cannot do that. The alpha channel contains independent info used when combining the image with a background.
The only way to convert is removing such a info.
