Gradient | SuperCollider 3.13.0 Help

Description

NOTE: The use of Gradient is not supported yet. When Gradient is used in place of Color, the average gradient color will be used instead.

Class Methods

Gradient.new(color1, color2, direction: 'h', steps: 64)

Arguments:

color1	An instance of Color.
color2	An instance of Color.
direction	`\h` or `\v` for horizontal and vertical respectively. Default value is `\h`.
steps	The resolution of the gradient. Default value is 64.

Instance Methods

.at(pos)

Retrieve the colour at position pos, typically a value between zero and one. at(0) is color1, and at(1) is color2.

Arguments:

pos

.fill(rect)

From extension in /Library/Application Support/SuperCollider/downloaded-quarks/wslib/wslib-classes/GUI/Extensions/extGradient-fill.sc

.penFill(rect, alpha: 1.0)

From extension in /Library/Application Support/SuperCollider/downloaded-quarks/wslib/wslib-classes/GUI/Extensions/extGradient-fill.sc

Examples

// basic usage
(
w = Window.new.front;
w.view.background = Gradient(Color.yellow,Color.white);
)

// change direction and resolution
(
w = Window.new.front;
w.view.background = Gradient(Color.red,Color.white,\v, 5);
)

// almost unnoticeable variations can be pleasant
(
w = Window.new.front;
v = CompositeView(w, Rect(50,50,300,300));
c = Color.rand;
d = c.vary(0.15);
v.background = Gradient(c, d, \v);
[c, d].postln
)

(
var w, k, c, d, e, c1, c2, f, g;
w = Window.new.front;
k = Slider2D(w, Rect(50,50,300,300));
f = {
    c = Color.rand;
    d = c.vary(0.5);
    e = d.vary(0.5);
};
g = {
    c1 = d.hueBlend(e, k.y).round(0.01);
    c2 = c.hueBlend(e, k.x).round(0.01);
    k.background = Gradient(c1, c2, \v)
};
f.value; g.value;
k.action = g;
k.mouseUpAction = { [c1, c2].postln };
k.keyDownAction = f; // hit any key for new color
)

// an example using gradient indirectly to update window colour
(
w=Window.new.front;
g = Gradient(Color.red,Color.green);
Task{
    (0, 0.01 .. 1).do{|pos|
        w.view.background = g.at(pos);
        0.01.wait;
    };
}.play(AppClock)
)
