Design Choice - Opinion Required: To Alpha Blend Or Not?

I would like opinion on whether to utilize alpha blending or not.

Say I have skin with a complex background shape, and complex alpha channel, that looks really good when the user has alpha blending on but looks pretty naff with alpha blending off. What should I do: carry on and don't worry about non-alpha users or bin it and go with a simpler shape that looks ok with or without alpha?

I don't know what percentage of users use alpha blending? If it was 75% I would go with the complex shape, less than that and I'm not sure.

I have read the thread about coding a warning if alpha is disabled, not sure if that option is enough to sway me.

Any ideas/opinion appreciated.


PS. When alpha is disabled, Winamp takes any 'non-255' pixel value in the alpha channel as a 100% transparent area, yeah?

I think you can avoid that problem by making it use different images when desktop alpha is off but I'm not 100% sure.

i dont use alpha on, its too much on the CPU on my system. i dont know about other systems. and alpha blending is not supported on all OS.

its not 'non-255', i think it comes with a threshold (maybe 128) or something.

mmm... most people do their skins with alpha blending (i guess) .... the smallest part of them cares how it'll look without desktopalpha. good skins though, have a second backgroundimage for no dta. (i don'T say a skin without that is a bad skin!)
making a nice and clean no-dta version of a backgroundimage isn't that easy in freeform, and many people fail here.
try it, it'S worth the effort

if a skin has rounded edges, and no antialiasing in the alpha channel, i won't use it. unless if the rounded edge is really small like winamp modern.

It is right that alphablending isn´t supported on all OS but today most users have WinXP. Even when you bought your computer at a supermarket you get it with WinXP. So...

But if my OS wouldn´t support it and I would try out this skin and see every pixel on the "round" edge ...

So if it is possible to create an acceptable non-alpha shape, do it and include it in the skin.
