Problem description:
I am working on a new interface after coming across some post I saw and was like why not try something new. Doing this I came across something that I didn't know if it was possible to do yet. Would I be able to make a rounded, irregular shape window by fading the background of the window or threw another method. Thanks.
I told him I know there's a library available, but I couldn't seem to find it. He wants a rounded interface, rather than a regular looking window.
It /might/ be doable, but as I recall, windows with transparent sections don't always work too well. You should be able to find your answers in the skin reference.

Ok thanks this seems to show how to do it from what I can tell I just have to match the background color of the image to what I want gone under the blend part.
Keep in mind, doing this will force your game into software rendering mode, which heavily limits the graphical power you have to utilize and is generally slower than hardware rendering mode.

This is a Windows limitation, not a BYOND limitation.
