u5.js is a minimalist and lightweight canvas animation library

When calling fill() and stroke() in the setup(), the fill and stroke styles are overridden after a canvas resize.
Example to reproduce
<!DOCTYPE html>
<html>
<body>
<div id="container"></div>
<script type="module">
import u5 from "https://www.unpkg.com/[email protected]/index.js";
const example = (sketch) => {
sketch.setup = function () {
sketch.createCanvas(sketch.windowWidth, sketch.windowHeight);
sketch.stroke("red");
sketch.fill("blue");
};
sketch.windowResized = function () {
sketch.resizeCanvas(sketch.windowWidth, sketch.windowHeight);
};
sketch.draw = function () {
sketch.rect(100, 100, sketch.width - 200, sketch.height - 200);
};
};
new u5(example, document.getElementById("container"));
</script>
</body>
</html>
Actual result: After resize, the rectangle is filled black with a black stroke
Expected result: After resize, the rectangle should be filled filled blue with a red stroke
When calling background()
after fill()
the fill style is overridden with the background style.
Example to reproduce
<!DOCTYPE html>
<html>
<body>
<div id="container"></div>
<script type="module">
import u5 from "https://www.unpkg.com/[email protected]/index.js";
const example = (sketch) => {
sketch.setup = function () {
sketch.createCanvas(sketch.windowWidth, sketch.windowHeight);
sketch.fill("blue");
};
sketch.draw = function () {
sketch.background("red");
// sketch.fill("blue");
sketch.rect(100, 100, sketch.width - 200, sketch.height - 200);
};
};
new u5(example, document.getElementById("container"));
</script>
</body>
</html>
Currently the ellipse
function is using parameters as radiuses of X/Y instead of width/height as in p5.js.
this.ellipse = function (x, y, rx, ry)
This should be
this.ellipse = function (x, y, w, h)
As a result, ellipses are drawn twice larger with u5.js.
Sketches which have a low framerate defined and resize the canvas when the window id resized, show some flickering behaviour.
Here is an example:
<!DOCTYPE html>
<html>
<body>
<div id="container"></div>
<script type="module">
import u5 from "https://www.unpkg.com/[email protected]/index.js";
const example = (sketch) => {
sketch.setup = function () {
sketch.createCanvas(sketch.windowWidth, sketch.windowHeight);
sketch.frameRate(25);
};
sketch.draw = function () {
sketch.background("white");
sketch.fill("black");
sketch.noStroke();
const d = Math.min(sketch.width, sketch.height) / 2;
sketch.ellipse(sketch.width / 2, sketch.height / 2, d, d);
};
sketch.windowResized = () => {
sketch.resizeCanvas(sketch.windowWidth, sketch.windowHeight);
};
};
new u5(example, document.getElementById("container"));
</script>
</body>
</html>
Actual result: Canvas flickers when resized
Expected result: Canvas should not flicker when resized
