check it out...
I have two art programs
they both use RGB sliders.
however....
one of these slides from 0 to 255
the other slides from -100 to 100
meaning pure black on the first scale is R0 G0 B0
but the same color on the other is R-100 G-100 B-100
see the problem?
I figure I need to make some kind of scale conversion thing.
like how thermometers have both the Fahrenheit and Celcius
I'm really hoping I don't have the draw this thing out on paper tho.
anybody know of an quick and easy way to set something like that up?
fucking scales!
Who would of thought you'd need algebra
Joe is correct. I substituted the numbers in to check his equations and they work.
If you didn't want to have to make the equations all over again you could probably plug them into Excel or a simaler spread sheet and get it done that way to use as a reference.
EDIT...
I thought it would be simplier then i'm finding it to do. It took literally 30 seconds to type in the two equations into my graphics calculator and get the values but my excel is very rusty.
It's a challenge for my poor befuddled mind,so i'm going to go and do it until i work it out. I'll email you a file of it
EDIT V1.2
Fuck it... i can't be fucked, i can't remember how to set parameters/field boundaries... it's all just a hell of a lot easier on my clunky ti82
