It would be great if - the modification applies uniformly to all the elements of the visualisation. - Control the modification using a button or a key combination (increase/decrease) I dont know if this possible but anyway, your solution looks fine to me :) Abdelghani > > Alexandre > > > >> On Feb 21, 2018, at 8:38 AM, abdelghani ALIDRA wrote: >> >> Hi Alex and thanks for your answer, >> By playing with the contrast I mean to change (dynamically) how visible >> lighter colors are from darker ones.

Re: [Pharo-users] Roassal : Playing with the contrast
I should remove it. And we should introduce this package in Pharo and I should do a pass on the image color initialize.

Re: [Pharo-users] Roassal : Playing with the contrast
Yes, I had a look at it. Indeed, it provides a nice set of utility methods. By the way, what the class ColorChecker does? I will make a plugin for it in Roassal.

Re: [Pharo-users] Roassal : Playing with the contrast
Well… you can change the color of any element (even if the visualization is open). Simply goes to the canvas and change the trachel shape. I can provide an example if you wish.

Re: [Pharo-users] Roassal : Playing with the contrast
--- Begin Message --- Hi Alex and thanks for your answer,By playing with the contrast I mean to change (dynamically) how visible lighter colors are from darker ones. And by dynamically, I mean I dont want to re-build the visu. To be more specific, I can have for a certain visu, a shape coloured with Color red and bordered with Color red slightlyDarker.At some point I would like to see the difference between these two colours and at some other point I dont. So for instance, I increase the contrast and I see the border of the shape them I decrease it then I see the shape uniformaly coloured. So, is there a way to do so?Thanks,Abdelghani De : Alexandre Bergel À : abdelghani ALIDRA ; Any question about pharo is welcome Envoyé le : Mercredi 21 février 2018 2h19 Objet : Re: [Pharo-users] Roassal : Playing with the contrast Hi!

Re: [Pharo-users] Roassal : Playing with the contrast
Hi! What do you mean with contrasts? You mean the colors? Currently, there is no way to automatically assign colors to a visualization, although you can use a color palette (look at the class RTPalette).
