How to convert RGB to background colors?

Hello,

I notice the setdefault background colors are between 0 and 1. How do I convert the three rgb colors to this? Not sure why they changed this…

Thanks,

Warren

In Graphics 2.0, all colors are now 0…1 instead of 0…255 (unless there is something we missed).  The easiest thing is to simply do a divide by 255.   25/255, 83/255, 240/255 if your previous colors were 25, 83, 240.

Thanks. Was there a big reason for making this change? I mean most graphics software reports the color in rgb still don’t they?

There is a thread running around in the Advanced Graphics section where this was discussed in some detail, but the short summary is:

0.255 limits us from doing more high-def graphics.  0…1 will allow us to support not only 8bit per channel graphics, but 16 and 32 bit as well.  We have to make the jump at some point to allow these higher dynamic range images to be used, so now seemed like the right time.
