1. 256 colors
Content-type: text/plain; charset=us-ascii

Hi Colin, or anybody else with interest in colors and/or bitmaps,
I need your help. Colors again: I want to combine the three attached clips in a
single screen, all of them, simultaneously, using just 256 colors.
I can convert each to a 256 color bitmap, no problem, with acceptable quality.
But when I attempt to get them down to about 85 colors each, the degradation is
just too great. There must be a way to force the bastards to share the same
palette - some sort of compromise, which would give a better result. Any ideas,
suitable tools?
BTW, don't just tell me to use Neil or TrueColor or similar. Please!
Thanks. jiri

Use one suitable 256-color palette and convert all 3 images to the same
palette. I got pretty good results using Photoshop to convert the images=
to the Mac palette with error diffusion dithering. I'll send you the pic=
s
privately.

I usualy use paint shop pro to do that kind of thing.
First load all the images and change them to 24bit true color,
then enlarge the canvas area of one of them and paste the others into the
new space. Then you can reduce the color depth to 256 colors and you will
have a common palette to use for the original images. you just have to load
the new palette for each of the original images.
hope that helps.

Thanks, Mark. I will certainly try your recipe later this week.
BTW, why do I have to change the format to 24bit first?

You don't. JPG's are always 24bit color.
The point was to ensure that the exact image colors where kept.
So that when you converted it to 256 color you would be starting
from the highest color quality.
