I found out https://yeschat.ai for html canvas

makes good explination about ZIM
To create a gradient page with ZIM on a Canvas, you can utilize ZIM’s built-in gradient methods. ZIM (a framework for HTML5 Canvas built on CreateJS) makes it simple to add gradients, shapes, and interactive elements to a canvas.
Here's how to create a gradient background for a ZIM page step-by-step:
1. Set up your HTML file:
Include the ZIM library in your project. You can link it directly from a CDN:
<!DOCTYPE html>
<html>
<head>
<title>ZIM Gradient Page</title>
<script src="https://zimjs.org/cdn/zim.10.9.0.js"></script>
</head>
<body>
<script>
// Your JavaScript goes here
</script>
</body>
</html>
2. Initialize the ZIM Frame:
The Frame
is the ZIM container for all your canvas content. You can specify its size and color.
// Initialize the ZIM frame
const frame = new zim.Frame("fit", 1024, 768); // "fit" makes it responsive
frame.on("ready", () => {
const stage = frame.stage; // The canvas stage
const canvas = frame.canvas; // The HTML5 canvas
3. Create the Gradient:
ZIM provides a new zim.Rectangle()
or new zim.Shape()
to which you can apply gradients. Use zim.makeGradient()
for easy gradient creation.
// Create a rectangle to cover the entire stage
const gradientRect = new zim.Rectangle(1024, 768)
.center(stage)
.fill(zim.makeGradient({
colors: ["#ff7eb3", "#ff758c", "#ff4a69"], // Gradient colors
ratios: [0, 0.5, 1], // Position of colors (start, middle, end)
x1: 0, y1: 0, // Start point of gradient
x2: 1024, y2: 768, // End point of gradient
alpha: 1 // Gradient opacity
}));
// Add the gradient to the stage
stage.update();
4. Finalize the Script:
Complete the script by closing the frame.on("ready")
block.
// Close the ready function
});
5. Full Example:
Here’s the complete example code:
<!DOCTYPE html>
<html>
<head>
<title>ZIM Gradient Page</title>
<script src="https://zimjs.org/cdn/zim.10.9.0.js"></script>
</head>
<body>
<script>
const frame = new zim.Frame("fit", 1024, 768); // Set up ZIM canvas
frame.on("ready", () => {
const stage = frame.stage;
// Create a gradient rectangle
const gradientRect = new zim.Rectangle(1024, 768)
.center(stage)
.fill(zim.makeGradient({
colors: ["#ff7eb3", "#ff758c", "#ff4a69"], // Gradient colors
ratios: [0, 0.5, 1], // Gradient positions
x1: 0, y1: 0, // Gradient start point
x2: 1024, y2: 768 // Gradient end point
}));
// Update the stage
stage.update();
});
</script>
</body>
</html>
Key Features:
- Responsive Frame: Use
"fit"
in zim.Frame()
for dynamic resizing.
- Gradient Control: Modify
colors
, ratios
, and the x1, y1, x2, y2
coordinates to customize the gradient's appearance.
- Additional Elements: Add more shapes, text, or animations to make the page interactive.
Feel free to expand this with buttons, animations, or text elements to enhance the canvas! Let me know if you need further guidance.
