how to mask desaturation over color, fade in

Christoph Hart

Well, then I will endorse the attempt of playing ScriptPanel programming in god mode. Here is a little help:

/** This namespace contains a few helper functions. */
namespace ColourOps
{    
    /** Takes the colour and saturates / desaturates it (saturation = 1.0 means no change). */
    inline function withMultipliedSaturation(colour, saturation)
    {
        // Commencing bit fiddling sequence
        local a = (colour & 0xFF000000);
        local r = (colour & 0x00FF0000) >> 16;
        local g = (colour & 0x0000FF00) >> 8;
        local b = (colour & 0x000000FF);
        
        // If you want to lower the saturation, you have
        // to fill up the colour values to the max colour
        local max = Math.max(r, Math.max(g, b));
        
        local rDiff = max - r;
        local gDiff = max - g;
        local bDiff = max - b;
        
        local invSat = 1.0 - saturation;
        
        r = parseInt(r + invSat * rDiff);
        g = parseInt(g + invSat * gDiff);
        b = parseInt(b + invSat * bDiff);
        
        // ending bit fiddling sequence...
        return a | (r << 16) | (g << 8) | b;
    }
}


Panel1.setPaintRoutine(function(g)
{
    var c = this.get("itemColour");
    
    // make it 2px wide so that it doesn't flicker with odd zoom ratios...
    var area = [0, 0, 6.0, this.getHeight()]; 
    
    // create the array before the loop to save a few CPU cycles
    var gradientData = [undefined, undefined, 0.0, Colours.black, undefined, this.getHeight()];
    
    // we update the saturation every 4px, that's enough
    for(var x = 0; x < this.getWidth(); x += 4)
    {
        gradientData[0] = ColourOps.withMultipliedSaturation(c, x / this.getWidth());
        gradientData[1] = x;
        gradientData[4] = x;
        
        area[0] = x;
        
        g.setGradientFill(gradientData);
        g.fillRect(area);
    }
});

@Christoph-Hart great information from a great guy :)
Thank you!

Christoph Hart

Oh wow I didn‘t see it was a GIF. You‘re actually making AfterEffects in HISE. Thats even more badass!!!

Now you need to implement rLottie export!

Haha...absolutely, would it be possible? That would really be awesome

A Former User

@ulrik Man this is completely out of this world! Awesome stuff!

MikeB

@ulrik I already thought that you can probably do things with HISE that don't have to do with music.
But this is awesome - great work
It would be nice if you keep us informed about the progress.
In any case, you are now my master of PaintRoutines :-)

ulrik

@MikeB @UrsBollhalder thank you :)
I will keep you updated

ulrik

@UrsBollhalder @MikeB
I promised to keep you updated so...
this is my journey to the panels & paint routines promised land, well at least some of it :)

@ulrik sick!

@ulrik Great!

This shows that Hise is not only an audio plugin development framework, it can be used for lot's of things :)

A Former User

@ulrik Insane.

Now someone make Super HISE Bros quick!

MikeB

@ulrik wow - absolutely fantastic

You must have worked on that for a minute or two? :-)
Awesome

A Former User

@ulrik Man this is something else really! That must have taken you a fair bit of work as well... Crazy good... I love it. Also... what's the background music? It's not Jarrett, it's probably not Bobo Stenson or Iiro Rantala... who is it?

ulrik

@UrsBollhalder thank you!
Yes I've spend a lot hours figuring out how to accomplish what I had in mind :)
the music is me

A fellow jazz pianist then! Love it!
