1. try to convert the picture to grayscale. You will get a nice gray gradient in 8 bit. Set a grayscale palette.
2. Use a better programm, which can downsample images from 24-bit to 8 bit web-palette (or Windows-palette, which I use always) with dithering.
3. Write your own dithering algorithm.
4. Switch to 16-bit mode

I must not be explaining my problem correctly. I keep getting replies telling me this is in the PILRC docs. But what I'm after isn't covered in those docs. Syntax and such is covered just fine but that's not what I'm asking about.
I'm having problem creating 3D buttons that don't have banding.
I have explained this here, since it has an embedded image that I wanted to show as an example.
http://www.msdsite.com/temp/button.html
Everytime I try to create a 3D image using PSP and reduce it to 8 bits, I get banding. I know the cause, but not the solution to fix this. I can only do 3D buttons in PSP using 24 bit mode. My images have far fewer than 256 colors.
I'd like hearing from those that create these high resolution 3D buttons that can explain the process.
Thanks,
