Hi,

i have a pictureBox with a BackgroundImage and a
Bitmap (Image) with some Transparent stuff and pixels
but no palette, because there're are more colors needed
although i could use less color, it doesn't seem to
work right to Initialize a Bitmap with PixelFormat
options.

So do you know who to implement a fade in/out effekt ?

Thanks,

Doint this with a PictureBox is nott a particularly good idea because PB
paints it's background before it displays the picture which would cause
flashing.

I suggest creating a control with two image properties and a timer. The
timer can be set to invalidate the control at a certain interval and the
images drawn so that the background is opaque and the foreground is
semi-transparent by using an ImageAttributes and a ColorMatrix set for
transparency adjustment.

See the GDI+ FAQ for articles on how to draw semi-transparent images.
