Need some help with rendering raster images in a different way

[kennethmjones]

Hello,

I want to make raster images not display pixels that have certain color values. I guess this is similar to making the background color of bitonal images transparent...

Has anyone ever done this?

Can anyone please offer some advice as to how I can go about coding this in arx, if indeed it is even possible. Right know I don't know where to start looking for ways to imlement this. I would really appreciate any advice that will make my journey shorter.

Many thanks in advance.

Ken
