Linear color normalizer

Alexandre Bergel
Hi!

I executed the following scripts:




I would actually expect the same node colors.
Apparently, the colors given by the normalizer are focused on 0. Is this what you would expect?

Cheers,
Alexandre

Re: Linear color normalizer

In my naive view this behavior looks OK. First example shows the last 5 colors in the progression, second example shows the first 5. I dont know how the color normalizer is expected to be used though ...

Re: Linear color normalizer

Actually, I think that the (faulty?) behavior Alex wants to demonstrate is this one:

|l|
l := MONColorLinearNormalizer inContext: (10 to: 15) lowColor: Color white highColor: Color blue.
view shape rectangle size: 20;
        fillColor: [ :n | l moValue: n ].
view nodes: (10 to: 15)

Sorry, my email did not make the point. Consider the following two examples:

Re: Linear color normalizer

jfabry

OK now I get it. Yes, for me both cases should show a range of 5 colors from white to blue. So it's a bug. But that's just my naive point of view of course ;-)

This is what I thought as well.
Simon told me he is fixing this.
He will ping us

Cheers,
Alexandre

Re: Linear color normalizer

In reply to this post by Alexandre Bergel
Simon proposed a fix for this problem. 3 tests were turned yellow.

With Simon fix:



Without Simon fix:



If you are a user of the color linear normalizer, please try your code and check if everything is alright. System complexity is not significantly impacted.

Cheers,
Alexandre
