I want to fade a picture, but it`s slow. Anyone know an
effective way to do this so the fading gets smooth?

I tried this code but it`s just to slow.

It is very slow - If you want to fade the screen, the easiest way is to get the screen as a sprite and fade that. Why, I've got just a routine on my web site.

If you just want to fade a bitmap, then you'll have to wait to see if they can speed it up.

Good news everyone! I really am THAT good...

Doesn't work on all machines, although that would be the prefered solution.

how about making lots of frames of the same pic with diferents colors and draw them to the front buffer in sequence creating a fake hard coded fade

i'd make a DLL and use that instead ... infact if you download 1.13 Extras for DB then there is one in there for use

Rogue: Gamma is a solution, but i have to know what cards it works on. It worked on my Geforce 2 mx.
But i also wanna have the possibility to have effects above the picture that should not be faded when the picture fades.

Raven Vegeta: Where can i download 1.13 Extras for DB?


Happy new year folks!

Hi guys just a lil piece of related info for you, sorry I'm late the set gamma commands worked well full screen in DB1 so long as it was in full screen. It didn't work in windowed mode which I attributed to being to do with not changing the gamma of the entire windows desktop. Thats probably also why it only works in DBPro under Full screen exclusive mode NOT full screen windowed. Unfortunately most people I think use the full screen windowed version as it is far more efficient, so therefore the easiest way to do it without an external plugin is to capture the screen, make a sprite, and fade that out as has been explained above

Would be good if we could set the refresh rate for full screen exclusive mode - that way it would be as fast as the windowed mode.

Unfortunately, I think its a DX9 only..

i don't understand why people use that Fullscreen Desktop mode, it looks horrible on my puter cause like i run at 1280x960 and the default render mode is 640x480
which doesn't come up pretty at all

Hey i reckon i could make a nice simple TPF for ya'll to achieve this - just setup a fade to the BackBuffer based on a time given, i dunno.
If anyone wants it i'll make it but lemme know how you'd want to control it.
